The clamp is a quick and effective way to slow the bleeding of traumatic wounds in the field. The plastic clamp includes long curved needles along its 'jaws'. The curved needles allow the wound to be drawn up into the device, where it is held with an even pressure that allows the blood underneath to form a clot and slow bleeding until further medical help is available.

A tiny new wireless sensor placed on a tooth will be able to monitor bacteria and transmit the data to an external sensor. The prototype sensor will be created by printing graphene onto water soluble silk, which will allow it to be transferred to the surfaces of biological materials. A resonator coil on the sensor will function as an antenna to allow wireless communication and provide power. The ability to detect bacterial contamination quickly will help to reduce the...

A new cannula system will dramatically increase patient comfort, automatically administering local anesthesia before the larger needle is inserted. The new cannula will look similar to conventional needles, but will include a tiny needle on the front that will deliver about 0.2 ml of local anesthesia. The design will decrease the steps involved in administering anesthesia while also reducing mistakes and infiltrated veins.

The environmentally friendly bandage will use nanobubbles to attack the protective surface of fungi and bacteria. The nanobubbles, which function similar to oil droplets, will operate in conjunction with a particular blend of polysaccharides, damaging the microbes' cell walls and causing them to dehydrate and die. The polysaccharides are less toxic and less expensive than the antibiotics and silver used in current germ fighting bandages.

A new method of using light and sound to detect circulating tumor cells could provide an early warning and allow the disease to be treated at an earlier stage. The photoacoustic melanoma detection device shines laser light into blood cell samples that possibly include cancer cells. The melanin inside the cancer cells absorb the light, which causes a high frequency acoustic response detected by sensors in the photoacoustic flow meter. This allows the cancer cells to be immediately...

A new method of stroke treatment is able to both restore circulation and remove clots with one insertion and has proven surprisingly effective. The device will be inserted into with a microcatheter. It will expand and trap the clot, and will be then retracted back to the catheter while the clot will be removed from the blood vessel by suction.

The new glasses will allow the user to change their refractive power, making it easier to provide corrective eyewear to people in developing nations. The inexpensive glasses will consist of a pair of fluid-filled lenses with flexible membranes. The wearer will use a small detachable pump to add or remove fluid from the lenses, adjusting their refraction to suit their need.

A gel will be able to speed the healing and regeneration of bones. The gel will be created by using the adult stem cells that will create a protein to promote bone healing. The stem cells will be incorporated into a gel which is supposed to be inserted into bone fractures in rats, which will help them heal completely in less than two weeks.

A new device will make it easier to monitor patients who are at risk for strokes without the need for invasive tests. Knows as near-infrared spectroscopy (NIRS), the small, thin device will attach to the patient's forehead like a sticker. It will measure blood oxygen levels in the brain using near-infrared light to penetrate the skin and reach the brain tissue, and readings can be taken simply by shining a light on the patient's brow. NIRS could replace the current methods of...

A new contact lens will be able to deliver anesthetic over an extended time in uniform doses, providing better comfort for post-eye surgery patients. The lenses will be created specifically with laser eye surgery patients in mind. The dosing them with vitamin E will extend the time of release of 3 common anesthetics from 2 hours to a whole day. The vitamin E will also function as a barrier, keeping the medication on the eye.
