Abstract

A delivery system for delivering an implant into a soft palate of a patient for treatment of snoring includes an implant and a delivery tool. The implant is formed from a sheet of flexible, bio-compatible material sized to be inserted into the soft palate. The delivery tool includes a penetrating member with a distal end for penetration into the soft palate through a small penetration wound. The implant is carried in the distal end of the penetrating member. A flattening tool is contained within the penetration member and constrained by the penetrating member against a bias for a distal tip of the tool to expand beyond a size of the penetration wound to approximately a width of the implant. The flattening tool is retractable between an extended position and a retracted position with the distal tip of the tool in the retracted position being smaller than the penetration wound. The penetrating member is retractable relative to the flattening tool when the flattening tool is in the extended position.

Claims

1. A delivery system for delivering an implant into a soft palate of a patient for treatment of snoring, said system comprising:

(A) an implant having;

(a) a sheet of flexible, bio-compatible material having a longitudinal length between a proximal edge and a distal edge, a transverse width and a thickness between upper and lower surfaces;

(b) said material sized to be inserted into said soft palate with said longitudinal length extending aligned with an anterior-posterior axis of said palate and with said thickness contained within a thickness of said soft palate

(B) a delivery tool having;

(a) a penetrating member with a distal end for penetration into said soft palate through a small penetration wound, said implant carried in said distal end of said penetrating member with said longitudinal dimension of said implant aligned with an axis of said penetration member;

(b) a flattening tool contained within said distal end of said penetration member and constrained by said penetration member against a bias for a distal tip of said tool to expand beyond a size of said penetration wound to approximately a width of said implant;

(c) said flattening tool retractable approximate to said implant length between an extended position and a retracted position with said distal tip of said tool in said retracted position smaller than said penetration wound;

(d) said penetrating member retractable relative to said flattening tool when said flattening tool is in said extended position.

2. A delivery system according to claim 1 wherein said flattening tool includes spaced apart spring members having distal tips biased to be spread apart a distance greater than an outer dimension of said penetrating member and retractable to a reduced dimension.
