AN ANASTOMOSIS DEVICE FOR A CHOLECYSTO-ENTEROSTOMY

摘要

An anastomosis device (11) for a cholecystoenterostomy comprises a first ring portion (14) intended to be placed inside a gallbladder (8), a second ring portion (15) intended to be placed inside a target portion (12) of an intestine, wherein the anastomosis device (11) is shaped to determine a passage hole (16) in the gallbladder wall and intestinal wall at the cholecystoenterostomy (13) and at least the first ring portion (14) is time-dependently shape changeable such that the bulk of individual pieces of the first ring portion (14) becomes smaller than the passage hole (16).
