Ultrathin PLLA Nanosheet to Surpass Conventional Suture Treatment

In an initial report on the fabrication of free-standing nanosheets for biomedical applications, scientists at Tokyo's Waseda University in Japan have developed a biodegradable thin film of only about 20 nanometers thickness that could replace surgical stitches.

Applying nanosheets with poly-L-lactide (PLLA) to the incisions of mouse stomachs, the team found that these centimeter-long biodegradable nanosheets healed the incisions without scarring or tissue adhesion.

Students embed stem cells in sutures to enhance healing

ScienceDaily (July 26, 2009) — Johns Hopkins biomedical engineering students have demonstrated a practical way to embed a patient's own adult stem cells in the surgical thread that doctors use to repair serious orthopedic injuries such as ruptured tendons. The goal, the students said, is to enhance healing and reduce the likelihood of re-injury without changing the surgical procedure itself.

Laser skin welding the suture of future for surgery

Doctors of the future may be able to trade their needle and thread for high-tech laser "skin welding."

 

Scientists at Tel Aviv University are testing use of laser beams to seal surgical incisions, allowing skin and internal tissue to heal more quickly after operations and accidents.

 

"The technique of sewing the human body with needle and thread is an old one that has existed for thousand of years," said Prof. Abraham Katzir.

Antimicrobial sutures reduce infections in brain shunt surgery

Children born with hydrocephalus, or "water on the brain" must have shunts implanted to drain the fluid away from the brain to reduce harmful pressure. While shunts do their job well, the rate of shunt infection in children is very high for a variety of reasons, which requires putting the child through another surgery to replace the shunt, bringing with it more hospital time, potential additional neurological complications and an increased risk of death.
