The best doctors strive to relieve their patients' burdens. A physician in Houston asked Rice University students to help him do so in the most literal way. A team of bioengineering seniors built a prototype device to literally lift the weight from obese patients who, while undergoing surgical procedures, might otherwise have trouble breathing.

Frustrated
by the flimsy, disposable construction of typical trauma shears, Scott
Forman, an emergency room physician, teamed up with Sandia National
Laboratories engineer Mark Reece to design a better tool. The result is a
shear that handle tough materials like Kevlar without having to be
thrown away afterward. And it has a few other cool features as well.

Cochlear
implants have restored basic hearing to some 220,000 deaf people, but
the microphone and electronics can be cumbersome and can prevent them
from participating in certain activities like swimming. Engineers have
designed a tiny prototype microphone that can be implanted in the middle
ear, and its form factor has been tested on cadavers. Tests on live
humans are still a few years away.

The
mitotic spindle is an apparatus that segregates chromosomes during cell
division. But following some nanosurgery conducted by Harvard
University, its structure may be more complex than the standard textbook
picture suggests. Using a femtosecond laser, researchers have shown the
true structure of its protein strands.

Engineers
at the University of Sheffield have developed a method of making
medical devices called nerve guidance conduits. Based on laser direct
writing, which enables the fabrication of complex structures from
computer files via the use of CAD/CAM, the polymer-based material will
assist nerves damaged by traumatic accidents to repair naturally.

A
team of Rice University students has invented a machine designed to
improve the process of correcting bone deformities in children.
Typically, bone correction devices are manually operated, which children
must remember to use and which introduces the possibility of damaging
fragile tissues and nerves. The new automated linear lengthener avoids
these risks.

More
than a million Americans receive an artificial hip or knee prosthesis
each year, but tens of thousands of people need early replacements
because of loosening joints. To help minimize these operations, a team
of chemical engineers at Massachusetts Institute of Technology has
developed a thin, layered coating for implants that helps promote bone
growth.

Researchers
reported at a recent Orthopedic Research Society meeting that
orthopedic implants "dip-coated" with modular growth factors can
stimulate bone and blood vessel growth in sheep. This new modular
approach, the report suggests, might be able to stimulate bone formation
without side effects.

Robotics experts at the University of California, Santa Cruz and the University of Washington have completed a set of seven advanced robotic surgery systems for use by major medical research laboratories throughout the United States.

Some of the most important components of a pacemaker are the leads, the series of wires led through key veins into the heart and then connected to electrodes. This critical failure point has been addressed by Cambridge Consultants’ new WiCS system, which uses a leadless electrode powered wirelessly with ultrasonic pulses.
