Estimating the term…
A bioresorbable drug-eluting biopolymer suture-free blood vessel anastomosis devices can be deployed to join two blood vessels and resorbed by the body over a predetermined time period after the blood vessel has become joined. The anastomosis device can include a hollow tube that is inserted interconnect the two vessels to be jointed. A non-piercing suture is wrapped around the vessel to secure the anastomosis. The anastomosis device can include hollow tube that extends along an axis from a first end to a second end. The ends can be fitted with elements that facilitate mechanical attachment of the vessel to the anastomosis device and provide for a secure seal.
A biopolymer anastomosis device for connecting a first blood vessel to a second blood vessel, the biopolymer anastomosis device comprising:
The biopolymer anastomosis device according to claim 5 wherein the non-piercing suture is formed from a material including dextrose rods and HFIP solubilized silk fibroin.
A method for joining a first blood vessel to a second blood vessel, the method comprising inserting a first end of a hollow tube into the first blood vessel and a second end of the hollow tube into the second blood vessel and wherein the hollow tube is formed of a blend that includes silk fibroin and a plasticizer.
