Biodegradable anastomosis device for small lumen structures

Drexel University
posted on 02/04/2010

Drexel University’s surgeons and biomedical engineers have designed the biodegradable anastomosis device (AD) to simplify and accelerate connecting small lumen structures and reduce the time a surgeon spends on a given procedure. Currently, small lumen (such as bile duct) anastomosis is performed by hand suturing, which is very time consuming and is associated with complications rate in the range of 18% to 24%. Drexel’s AD is designed to shorten the anastomosis procedure time to 1-2 minutes. The AD has fixed diameter opening guaranteeing the passage of fluids carried by the small lumen structure and preventing obstruction of the lumen at anastomosis site. In addition to AD a dedicated Applicator was designed to facilitate the placement of AD. The design of the Applicator can enable the use of AD in laparoscopic surgery.

Suggested Uses

- Anastomosis of small lumen structures such as bile duct and small blood vessels

- Laporoscopic and robotic surgery

- Anastomosis of large lumen structures

- Pancreatic and liver cancer surgeries, liver transplantaion


- Significantly shortened time of anastomosis procedure, down to about 1-2 min

- Replaces hand suturing with a simple installation procedure

- Potentially reduced morbidity at anastomosis site

- Optional drug delivery capability can further accelerate healing and reduce anastomosis-related complications
