Intraintestinal bypass graft
First Claim
1. A bypass graft suitable for attachment in the lumen of a resectioned intestine or duct upstream of the anastomosis thereof comprisingan elongated tube having proximal and distal ends and formed of a thin water-impervious wall material having sufficient flexibility to conform to the natural movements of the intestine or duct surrounding it, andreinforcing means extending around the proximal end of said tube for rendering said end stronger than said thin wall material but still sufficiently flexible to conform to said natural movements,with said elongated tube abruptly terminating at its distal end in a relatively short nipple of substantially reduced cross-section.

Abstract
An improved intraintestinal bypass graft for attachment in the lumen of a resectioned intestine or duct upstream of the anastomosis site in order to protect the healing anastomosis comprises an elongated tube formed of a thin, highly flexible, water-impervious wall material terminating at its distal end in a short, reduced diameter nipple. The surgical procedure for implanting the bypass graft can be simplified and shortened in time by readily fitting the distal nipple over one end of an elongated pliable leader, or alternatively over the terminal anvil nut of a circular anastomosis surgical stapler, and then drawing the leader or stapler body through the patient'"'"'s anus to pull the distal end of the bypass graft out of the anus. The need to tie the distal end of the bypass graft to the leader or surgical stapler is eliminated.
