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.

The invention claimed is: 1. An intragastric device for the treatment of obesity, the intragastric device comprising:an intragastric member comprising a generally tubular sheet of material having a lumen extending there through, the intragastric member partitioned into a first bundle and a second bundle disposed proximal of the first bundle, the first and the second bundles formed by a first retaining member and a second retaining member, the first retaining member disposed between the first and second bundles, the second retaining member disposed proximal of the first retaining member and proximal of the second bundle, the first and second retaining members extending circumferentially about the 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 intragastric member comprise a meshed sock-like structure, and the first and the second retaining members are interwoven about the mesh;wherein the first and the second bundles are each movable from a longitudinally extended configuration to a longitudinally compressed configuration,wherein the first and second suture ties are configured to move the first and second bundles from the longitudinally extended configuration to the longitudinally compressed configuration, andwherein 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 secure the first and the second bundles in the longitudinally compressed configuration.
