Miniature implantable sensor likely lifesaver for patients

...sors and associated electronics, which will enable surgeons to implant the sensor in the precise area of interest, either as a subdermal or deep-tissue implant. Ericson envisions the sensor remaining in the body, which would avoid additional surgery; however, that is an area that may require additional evalua...

Beyond patches and pills: the remarkable future of drug delivery

...lk again. The knot that ties itself -- Sometimes surgeons do operations in areas of the body that are very hard to access, making it almost impossible to tie a suture. To help them, scientists have manipulated tissue-engineering polymers to make materials that change shape upon a change in conditions -- suc...

Researchers develop 'natural bandages' that mimic body's healing process

...sometimes in surgery there are small bleeders that surgeons can't control," Bowlin says. "In this case, they can just take a small piece of this mat, slap it down, stop the bleeding and leave it. Similar to what people use when they cut themselves shaving just put a little dab on there and it's done." The re...

Study of living eye in real time now possible with optics technology

...orda's device might be microretinal surgery, where surgeons need a clear view of an area they would like to treat. "The way we use our laser to scan the retina to produce an image, it may be possible to use the technique for treatment. While you're imaging a microaneurysm, for example, if we could track that ...

While the risk may be low, the potential nevertheless exists that patients could develop allergies, or even disease, from the cosmetic injections. But that risk may soon be eliminate...

Research and development takes robots and automation into new territory

Dexterous, voice-controlled robots can facilitate efficient microscale operations by eliding hand tremors and offering visual magnifications. "Surgical robots ena...

New study: percentage of babies born with intestinal birth defect growing in U.S., N.C.

...mewhere between 3 percent and 8 percent. Pediatric surgeons replace the intestines during surgery, but since they don't work well at first, it takes babies a long time to recover, and many of them will spend an average of 30 to 40 days in the hospital." The UNC doctors and their colleagues decided to analyze ...
