INTRALUMINALLY DIRECTED ANVIL APPARATUS AND RELATED METHODS AND SYSTEMS

摘要

Anastomosis procedures are achieved through the use of an intraluminally directed anvil apparatus (200). The apparatus (200) is inserted at a cathete r site (140') and is then positioned through the lumen of the blood vessel (20 ) to a remote anastomosis site. The intraluminally directed anvil apparatus (200) has an anvil pull (230') extending from an anvil (210'). At the anastomosis site, the anvil (210') is extended through the wall of the vesse l at an initial piercing (15). The anvil (210') is too large to pass through t he initial piercing (15) so the anvil pull (230') can be used to pull the anvil (210') against the wall of the vessel and distend the vessel wall in preparation for being cut to form an opening. The apparatus (200) is used wi th a cutter to form openings in a wall of a blood vessel. After the opening is formed then the vessel is joined with another vessel.
