ROBOT TREATS BRAIN CLOTS WITH STEERABLE NEEDLES

est with phantom blood clot made out of gelatin. (Credit: Joe Howell / Vanderbilt) That is the basic premise of a new image-guided surgical system under development at Vanderbilt University. It employs steerable needles about the size of those used for biopsies to penetrate the brain with minimal damage and suction away the blood clot that has formed. The system is described in an article accepted for publication in the journal IEEE Transactions on Biomedical Engineering. It is the product of an ongoing collaboration between a team of engineers and physicians headed by Assistant Professor Robert J. Webster III and Assistant Professor of Neurological Surgery Kyle Weaver. The odds of a person getting an intracerebral haemorrhage are one in 50 over his or her lifetime. When it does occur, 40 percent of the individuals die within a month. Many of the survivors have serious brain damage. Operations to “debulk” intracerebral hemorrhages are not popular among neurosurgeons: They know their efforts are not likely to make a difference, except when the clots are small and lie on the brain’s surface where they are easy to reach. Surgeons generally agree that there is a clinical benefit from removing 25-50 percent of a clot but that benefit can be offset by the damage that is done to the surrounding tissue when the clot is removed. Therefore, when a serious clot is detected in the brain, doctors take a “watchful waiting” approach -administering drugs that decrease the swelling around the clot in hopes that this will be

enough to make the patient improve without surgery. For the last four years, Webster’s team has been developing a steerable needle system for “transnasal” surgery: operations to remove tumors in the pituitary gland and at the skull base that traditionally involve cutting large openings in a patient’s skull and/or face. Webster’s design, which he calls an active cannula, consists of a series of thin, nested tubes. Each tube has a different intrinsic curvature. By precisely rotating, extending and retracting these tubes, an operator can steer the tip in different directions, allowing it to follow a curving path through the body. The single needle system required for removing brain clots was actually much simpler than the multi-needle transnasal system.The brain-clot system only needs two tubes: a straight outer tube and a curved inner tube. Both are less than one twentieth of an inch in diameter. When a CT scan has determined the location of the blood clot, the surgeon determines the best point on the skull and the proper insertion angle for the probe. The angle is dialed into a fixture, called a trajectory stem, which is attached to the skull immediately above a small hole that has been drilled to enable the needle to pass into the patient’s brain. The surgeon positions the robot so it can insert the straight outer tube through the trajectory stem and into the brain. He also selects the small inner tube with the curvature that best matches the size and shape of the clot, attaches a suction pump to its external end and places it in the outer tube. Guided by the CT scan, the robot inserts the outer tube into the brain until it reaches the outer surface of the clot. Then it extends the curved, inner tube into the clot’s interior. The pump is turned on and the tube begins acting like a tiny vacuum cleaner, sucking out the material. The robot moves the tip around the interior of the clot, controlling its motion by rotating, extending and retracting the tubes. According to the feasibility studies the researchers have performed, the robot can remove up to 92 percent of simulated blood clots. “The trickiest part of the operation comes after you have removed a substantial amount of the clot. External pressure can cause the edges of the clot to partially collapse making it difficult to keep track of the clot’s boundaries,” said Webster. The goal of the future project is to add ultrasound imaging combined with a computer model of how brain tissue deforms to ensure that all of the desired clot material can be removed safely and effectively.


MEMS: SMARTPHONES AND PROSTHETICS AT A MICRO –SCALE…!!!

iny sensors and motors are ubiquitous, ranging from smart phone screens to cameras. A team of researchers at Tel Aviv University have devised a way to print biocompatible components for these micro-machines, making them ideal for use in medical devices, like bionic arms. Microelectromechanical Systems, better known as MEMS, are usually produced from silicon. The innovation of the TAU researchers has brought to fore a novel micro-printing process that works on a highly flexible and non-toxic organic polymer. The resulting MEMS components can be more comfortably and safely used in the human body .That they help conserve energy serves as an added advantage. As the name suggests, MEMS bridge the worlds of electricity and mechanics. Their applications encompass a wide gamut of fields, namely consumer electronics, automobiles and medicine. MEMS sensors, like the accelerometer that orients your Smartphone screen vertically or horizontally, are known to gather information from their surroundings by converting movement or chemical signals into electrical signals. MEMS actuator, which may focus your next Smartphone’s camera, performs the reverse operation, executing commands by converting electrical signals into movement. Both types of MEMS devices depend on micro- and nano-sized components, such as membranes, either to measure a parameter or produce the necessary movement. For years, MEMS membranes, like other MEMS components, were primarily fabricated from silicon using a set of processes used in the semiconductor industry. TAU’s innovative printing process, published in Microelectronic Engineering and presented at the AVS 59th International Symposium in Tampa, FL, yields rubbery, paper-thin membranes made of a particular kind of organic polymer. This material has some spectacular properties that yield a wide operational range from micro scale to nanoscale sensors and actuators. More importantly, the polymer membranes are more suitable for implantation in the human body than their silicon counterparts, which partially stems from the fact that they are hundreds of times more flexible than the conventional membranes. The unique properties of the polymer membranes have disclosed some unprecedented possibilities. Their flexibility helps make MEMS sensors more sensitive and MEMS motors more energy efficient. They could pave the way for better cameras and smart phones with a longer battery life. But the printing process may deliver the biggest jolt to the field of medicine, where

polymer membranes could be used in devices like diagnostic tests and smart prosthetics. There already exist bionic limbs that can respond to stimuli from an amputee’s nervous system and the external environment, and prosthetic bladders that regulate urination for people paralyzed below the waist. Switching to MEMS fabricated with the polymer membranes could help make such prosthetic organs more comfortable, efficient, and safer for use on or inside the body. “The use of new, soft materials in micro devices stretches both the imagination and the limits of technology,” says a member of the TAU research team, “but introducing polymer MEMS to industry can only be realized with the development of printing technologies that allow for low cost mass production. The team’s new polymer membranes can already be quickly and inexpensively produced. The polymer base for the membranes was supplied along with a grant by French chemical producer Arkema / Piezotech. “They just gave us the material and asked us to see what devices we could create with it. This field is like Legos for grown ups.” The next step, she says, is to use the printing process to make functional sensors and actuators almost entirely out of the polymer at the microand nano-scales. Such flexible machines could be put to use in things like artificial muscles and screens so flexible that you can roll them up and put them in your pocket. Quite a groundbreaking innovation, that one!!!

hen you successfully clear your semester exams, you end up getting a new phone. Maybe you trade in your old phone, or donate it. You might even just lock it away, but what if instead of any of those options, it simply dissolved? That’s the kind of future we could live in soon. Thanks to the development of “transient electronics.”They are devices meant to serve a specific function before completely dissolving into their environment over a predetermined span of weeks, months, or even years. In fact, your own body might be one of the first places these devices are deployed. “This message will self-destruct in five seconds” — it’s a scene straight out of Mission: Impossible that’s now becoming reality. University of Illinois engineering professor John A. Rogers is leading the development of “Transient ElectronicsOne of the major applications of “transient electronics” is in the medical field. The researchers involved have started off by designing a chip that dissolves when it hits water and so all your cell phone details are destroyed when you lose your phone; eventually, the team wants your entire phone to become electronic compost. This advancement could also introduce new design paradigms for medical implants, environmental monitors and other consumer devices. The current prototype chip is made out of magnesium, silicon and silk. According to scientists, the action of these elements dissolving in water occurs naturally in the environment and inside the human body — in other words, no harmful byproducts or chemicals are involved. The structure of the silk determines the rate of dissolution, which can range from minutes to years.

ope you all have spent at least some time juggling your brain on the previous edition of puzzles. This set is more promising and rejuvenating than ever. As always, the difficulty increases with number. I wish you good luck for the mental adventure you are about to plunge into.

1. Caesar simply replaced each letter in a message with the letter that is three places further down the alphabet. Cryptographers often think in terms of the plaintext alphabet as being the alphabet used to write the original message, and the cipher text alphabet as being the letters that are substituted in place of the plain letters. When the plaintext alphabet is placed above the cipher text alphabet, as shown below, it is clear to see that the cipher text alphabet has been shifted by three places. Hence this form of substitution is often called the Caesar Shift Cipher. A cipher is the name given to any form of cryptographic substitution, in which each letter is replaced by another letter or symbol Here, we have made slight modifications to the above idea and present you the encrypted word. Solve it. UGFYJSLMDSLAGFK 2. Two children, who were all tangled up in their reckoning of the days of the week, paused on their way to school to straighten matters out. “When the day after tomorrow is yesterday,” said Priscilla, “then ‘today’ will be as far from Sunday as that day was which was ‘today’ when the day before yesterday was tomorrow!”On which day of the week did this puzzling prattle occur? 3. There are 100 mathematicians (including you!) on an island. A booming voice comes down from the sky and says “In an hour, I am going to line you up and place a hat on each of your heads either black or white. You can see the hat colors of everyone in front of you in line, but you cannot see those behind you nor the one you are wearing. I will start at the back of the line (the person who can see everyone else) and ask your hat colors. If you get your hat color correct, you live. If not, you die. You may only guess black or white. If you communicate in any way, I will kill you all. However, you can hear the guesses of everyone behind you. You have an hour.” What scheme should you use to ensure that the most people survive? How many people can you guarantee you’ll save? For example, if the back person guesses the more common hat color that he sees and everyone else guesses the same color, at least 50 people will live. 4. During one meeting with a clan of ninjas, it has been noticed that more ninjas have turned up to the meeting than usual. The ninjas realized that these infiltrators must be the enemy of the ninjas (the pirates) dressed up as ninjas. Each person dressed as a ninja at the meeting made a statement. The cunning ninjas lied about their fellow ninjas in order to maintain secrecy and told the truth about the pirates. The pirates tried to mock the cunningness by lying about the pirates and telling the truth about the ninjas. From the following statements, can you identify the ninjas and pirates? Ninja A: Ninja B is a ninja Ninja B: Ninja C belongs to Ninja A’s group Ninja C: Ninja C doesn’t belong to Ninja F’s group Ninja D: Ninja A belongs to Ninja B’s group Ninja E: Ninja B belongs to Ninja C’s group Ninja F: Ninja E belongs to Ninja A’s group Remember, the ninjas and pirates will lie about individual ninjas or pirates, not groups of ninjas or pirates.

Medical microchipping is real

Scientists develop tiny electronics that dissolve inside your body f you thought the concept of medicallyinjectable microchips was something out of a science fiction novel, think again. A cohort of scientists from universities around the world have developed a new type of implantable microchip capable of performing various preprogrammed functions inside the body for a certain period of time, and later dissolving into oblivion. One example of this might be implantable chips designed to target open wounds with heat in order to prevent infection, particularly during patients’ time at hospitals, says a BBC piece on the subject. Another use might perhaps be to trigger an immune response that targets a potentially deadly infection, seeing as how conventional medicine has largely rejected the much more effective holistic and nutrition-based approaches for preventing and treating disease. According to reports, test chips have already been created that are composed of a combination of silicon and magnesium oxide, and coated in a protective layer of silk produced by extracting silk from silkworms, dissolving it, and reforming it into a crystallized coating. Depending on the intended lifespan of a particular chip, the thickness of the silk might be extremely thin to last for just a few hours, or slightly thicker to last for days or even weeks. While a cell phone that breaks down after two years might not sound that great, it could solve the problem of massive e-waste in landfills. Other benefits of self-destructing tech could be the security issues the medicinal field is concerned with, better temporary solutions for implantable medical devices that don’t require surgery to be removed. Considering it’s a relatively new category of electronics, researchers could also develop entirely new classes of devices that use the technology in some years.

“There will always be a frontier where there is an open mind and willing hand”

A little about my experience at University of South Florida. My journey through the master’s program here at USF was no easy task. Unfortunately i was among the few people who was at the wrong place at the wrong time. USF had just then decided to move all VLSI courses to the Computer science department and the consultancy that I applied through had no idea about this shift. So i was here in the wrong department looking out for the complete wrong course. Although I did end up taking the courses i wanted to from different departments and finally graduated, a

little guidance from someone before coming here would have helped and saved a lot of time and trouble. LESSON 1:So,contact your alumnis and get all the information before going for higher studies.Though the consultancy people will tell you everything, nothing helps like talking to someone who had an experience.The exposure to the american way of life while you are with people of your hometown is something truly awesome that one should experience. A little about my experience at MSEC. MSEC has been a great stepping stone for me. I personally have learnt a lot from my undergraduate years both academically and as a professional. It taught me how to survive outside of our concern zone.The various programs like E-CUBE and AVALANCHE helped me to meet like minded people among global diversities and communicate with them at ease. Some may say MSEC was a very strict college with many rules, but according to me they were for a reason and things worked out well for me.If I had been in some other college , I am not sure I would have made it this much in my life. I am honored to have MSEC as my alma mater.Thanks to principal madam for everything. AShanraam Sayeeram 2007-2011.
