A team of NIH-funded researchers has successfully regenerated rabbit joints using a cutting edge process to form the joint inside the body, or in vivo. Regenerative in vivo procedures are performed by stimulating previously irreparable organs or tissues to heal themselves. In this study, bioscaffolds, or three-dimensional structures made of biocompatible and biodegradable materials in the shape of the tissue, were infused with a protein to promote growth of the rabbit joint.

Minimally invasive surgery has experienced tremendous advances in the past decade. New systems incorporate robotics and increasing flexibility, but their size and cost limit widespread use. In addition, only a small percentage of surgeons undertake the steep learning curve required to master minimally invasive techniques. A new compact robotic system created by Columbia University researchers gives surgeons a highly flexible, user-friendly tool with three-dimensional imaging to operate in tight spaces

Taking advantage of the agility and inherent dexterity of the tongue, researchers at the Georgia Institute of Technology have developed a tongue-operated device that can help paralyzed people return to active, independent, and productive lives.

To treat deep vein thrombosis (DVT), a condition in which blood clots form in the veins of the lower legs, physicians currently have two options: systemic drug therapy or invasive clot removal. Both carry a risk of major bleeding and require a hospital stay. A new technique developed by University of Michigan researchers offers a noninvasive, localized treatment that nearly eliminates bleeding risk. The technique, called histotripsy, uses focused sound waves to break up clots and could make DVT treatment an outpatient procedure.

Using magnetic resonance imaging (MRI), clinicians can pinpoint potentially lethal plaques that accumulate in the main artery leading to the brain. However, MRI cannot predict which plaques may rupture and cause a stroke. A new computer model developed by researchers at Worcester Polytechnic Institute, Mass., Washington University, St. Louis, Mo., and the University of Washington, Seattle, provides such an assessment by calculating the structural stresses each plaque experiences. The model offers physicians a more precise way to evaluate each plaque and tailor treatment to individual patients.

Although current laboratory tests and imaging studies cannot predict whether a tumor will spread quickly, a new imaging technique – hyperpolarized carbon-13 MRI—developed by researchers at the University of California, San Francisco and GE Healthcare may provide new insights into how tumors use energy. The technique could help clinicians more precisely tailor therapies to slow or halt a tumor’s progress.

Researchers have designed a fist-like surgical tool the size of a dust particle that can open and close in response to chemicals or heat. The device, called a microgripper, does not require batteries or any electrical source and some day could be used to collect biopsy samples, remove blood clots, and deliver drugs to parts of the human body that wired tools cannot access.
