AN APPLIER AND A METHOD FOR ANCHORING A LINING TO A HOLLOW ORGAN

摘要

An endoluminal applier (1) for anchoring a tubular lining (9) to a hollow organ (10) comprises a staple fastening assembly (2) with an open arch shaped cartridge device (3) and an open arch shaped anvil (6) movable relative to the cartridge device (3) for clamping a tissue portion between first and second clamping surfaces (5, 7) and adapted to form the ends of staples exiting from the cartridge device (3), wherein the staple fastening assembly (2) comprises an open arch shaped lining seat (8) adapted to unilaterally holding the tubular lining (9) such that a ring shaped anchoring portion (12) of the lining (9) is constrained to overlap one of the clamping surfaces (5, 7) and the row of staples (4) along a first part (41) of a circumference of the anchoring portion (12), and the anchoring portion (12) extends outside said clamping surfaces (5, 7) along a second part (42) of its circumference.
