Wound

RevMedx's XStat syringe injects hemostatic sponges into deep wounds to control hemorrhage ...

Uncontrolled hemorrhage (bleeding out) is responsible for 80 percent of combat deaths. About the same proportion of those who die after being evacuated to a medical treatment facility also die of hemorrhage, usually associated with deep arterial wounds that cannot be treated using tourniquets – people die because we can't plug a simple hole. Now RevMedX, a small Oregon startup, has developed an alternative approach to treat such potentially survivable injuries.  Read More

One of the prototype ulcer-healing patches

Venous ulcers are nasty things, often found on the lower extremities of elderly or inactive people. They occur when high blood pressure causes the skin adjacent to the affected veins to break down, leaving open wounds that take months or even years to heal. Standard treatments include compression bandages, infection control and standard wound dressings, although these approaches don’t work in all cases. Now, however, scientists are getting good results using band-aid-like patches that emit ultrasound into the ulcers.  Read More

A material currently in development works in the same fashion as a scab, to accelerate the...

While you may think that standard bandages already serve as sort-of artificial scabs, the fact is that they mainly just compress and protect the wound – a scab, on the other hand, actually helps it heal. Now, however, scientists are working on a wound dressing that promotes healing in the same fashion as a scab.  Read More

Stitches and staples may be on their way to becoming a thing of the past, thanks to a developing technology known as laser tissue welding. Now, a new gold-based solder has been created, that could make tissue welds in regions such as the intestines much stronger and more reliable.  Read More

Animation still of the DARPA foam being injected

The Defense Advanced Research Projects Agency (DARPA) is developing a foam that can be injected into the body cavities of battlefield wounded to protect them from internal abdominal bleeding. The agency hopes that when perfected, this polyurethane polymer foam will help the wounded to survive the critical minutes needed to transport them to proper surgical facilities for treatment.  Read More

Sutures have come along way from the days of silk and catgut, but now they’re poised to make their biggest change in 3,000 years. They’re getting smart. John Rogers, professor of materials science and engineering at the University of Illinois at Urbana-Champaign has invented a “smart” suture that contains ultrathin sensors that can detect when a wound is infected and may one day be able to actively promote healing as well.  Read More

A solution containing skin cells and proteins has been shown to speed the healing of venou...

According the UK’s National Health Service, one person in 50 over the age of 80 will develop venous leg ulcers. The ulcers occur when high blood pressure in the veins of the legs causes damage to the adjacent skin, ultimately resulting in the breakdown of that tissue. While the ulcers can be quite resistant to treatment, a team of scientists is now reporting success in using a sort of “spray-on skin” to heal them.  Read More

ETH scientist have developed a specially contoured silicone that accelerates wound healing...

Even the smallest wound is potentially serious, so something as simple as a finger plaster and a little disinfectant can make the difference when it comes to preventing a nasty infection. But a dressing can do more than just keep out germs. That’s the idea behind work of the Laboratory of Thermodynamics in Emerging Technologies (ETH) in Zurich, Switzerland, where Prof. Dimos Poulikakos and his team of engineers and biologists are developing a new plaster that not only protects a wound from infection, it can also accelerate healing through the use of specially contoured silicone that promotes cell migration.  Read More

The growth of these blood vessels was caused and directed by the microvascular stamp

In the not-too-distant future, wounds may be covered not just with regular bandages, but with special "microvascular stamps" that promote and direct the growth of new blood vessels. A team of scientists from the University of Illinois have already created such a dressing, which could ultimately have applications far beyond the healing of cuts.  Read More

Third-degree burns typically require very complex treatment, and leave nasty scars once they've healed. Researchers at Johns Hopkins University, however, are reporting success at treating such burns on lab mice, using a new type of hydrogel that grows new skin (as opposed to scar tissue) over burn sites. The gel contains no drugs or biological components - it's made mainly from water and dissolved dextran, which is a sugar-like polymer.  Read More
