METHOD OF DELIVERING AN INTRAGASTRIC DEVICE FOR TREATING OBESITY
First Claim
1. An intragastric device for the treatment of obesity, the intragastric device comprising:
- an intragastric member comprising a generally tubular sheet of material, the intragastric member partitioned into a first bundle and a second bundle disposed distal of the first bundle, the first and the second bundles formed by a first retaining member and a second retaining member, the second retaining member disposed distal of the first retaining member, the first and second bundles extending circumferentially to form a lumen;
a first suture tie and a second suture tie, the first suture tie comprising a first proximal end and a first distal end, the first proximal end being a first free end that extends within the lumen and the first distal end affixed to the first retaining member, the second suture tie comprising a second proximal end and a second distal end, the second proximal end being a second free end that extends within the lumen and the second distal end affixed to the second retaining member;
wherein the first suture tie comprises a first ratcheted element and the second suture tie comprises a second ratcheted element, the first and the second ratcheted elements adapted to cinch the first and the second bundles.

Abstract
An intragastric member and method of delivery thereof are described. Delivery of the intragastric member is enabled by partitioning the intragastric member into discrete bundles with retaining members that are circumferentially disposed along the longitudinal length of the intragastric member. Formation of the intragastric member into bundles facilitates controlled delivery into the gastric lumen. The use of suture ties enables deployment of the intragastric member into the gastric lumen. The distal ends of the suture ties are affixed to the bundles. Pulling on the proximal free end of each of the suture ties enables the corresponding bundles to be advanced distally along a delivery tube. The suture ties are pulled until each of the bundles slide off from the delivery tube and enter into the gastric lumen

16. A method of treatment of obesity in mammals, the method comprising the steps of:
-
(a) providing an intragastric member comprising a generally tubular sheet of material; (b) securing the intragastric member onto a delivery tube with a retaining member, the retaining member extending circumferentially about the intragastric member to partition the intragastric member into a first and a second bundle, the second bundle positioned proximal of the first bundle; (c) securing the retaining member with a suture tie comprising a proximal and a distal end, the proximal end being a free end that extends within a lumen and the distal end affixed to the retaining member, and (d) pulling the proximal end of the suture tie in a proximal direction through the lumen so as to advance the first and the second bundles distally along the delivery tube. - View Dependent Claims (17, 18, 19, 20)
