Abstract:
1. A submucosal implant system, comprising: a gastric stimulator; a submucosal tunneling instrument having an elongate tubular member having proximal and distal ends and a lumen extending therethrough and an expandable member having proximal and distal ends wherein the proximal end of said expandable member is attached to the distal end of said tubular member and the distal end of said expandable member is everted and positioned within the lumen of said tubular member, said expandable member when expanded expanding substantially greater in a lengthwise dimension than in diameter, wherein the distal end of said elongate tubular member is adapted to enter an opening through the mucosal layer and into the submucosal layer of a mammal and adapted such that when said expandable member is positioned in the submucosal layer and expanded, said expandable member is adapted to longitudinally expand into the submucosal layer to form a submucosal elongate tunnel having a diameter and a length substantially greater than the diameter; and a submucosal dissecting instrument discrete from said tunneling instrument such that said tunneling instrument is adapted to be removed from the formed submucosal elongate tunnel and said dissecting instrument is adapted to be separately insertable into the formed submucosal elongate tunnel, said submucosal dissecting instrument having a distal end that when operated expands substantially greater in a lengthwise dimension than in diameter, wherein said distal end of said dissecting instrument is adapted to be inserted into the formed submucosal elongate tunnel and when expanded cause dissection of an area having a diameter substantially larger than the diameter of the formed submucosal elongate tunnel.
