Anastomosis member for anastomosis of blood vessels and anastomosis method using the anastomosis member

摘要

An anastomosis member has a generally cylindrical body comprising a plate member to be brought into contact with first and second blood vessels. The plate member is arranged in contact with the first and the second blood vessels at an anastomosed site where the first and the second blood vessels are anastomosed to each other. The plate member is provided with a plurality of protrusions formed on at least one of opposite surfaces thereof. The protrusions are engaged with at least one of the first and the second blood vessels to avoid the dislocation of the first and the second blood vessels at the anastomosed site.
