Abstract

Various methods and devices are described for retaining a medical implant within a body cavity. According to one aspect, at least a portion of a medical implant is positioned within a body cavity, and a wall of the body cavity is re-shaped such that the re-shaped wall prevents migration of the medical implant out of the body cavity. The re-shaped body wall may form a tissue pocket, tunnel, or other barrier against migration of the implant.

Claims

1-157. -157. (canceled)

158. A method of treating obesity in a patient, the method comprising the steps of:

forming a tissue fold in a wall of stomach tissue;

creating a perforation through the tissue fold; and

coupling an implant to the tissue fold by passing a portion of the implant through the perforation, the implant causing restriction of food consumption by the patient.

159. The method according to claim 158, wherein the tissue fold includes at least two layers of stomach wall tissue, and wherein the method further includes the step of securing the tissue layers to one another.

160. The method according to claim 159, wherein the securing step includes securing the tissue layers using sutures.

161. The method according to claim 159, wherein the securing step includes securing the tissue layers using staples.

162. The method according to claim 159, wherein the perforation includes edges and wherein the securing step includes securing the tissue layers around the edges.

163. The method according to claim 158, wherein the forming step includes the step of drawing a portion of the stomach wall inwardly to form the tissue fold, the tissue fold including layers of serosal tissue positioned in contact with one another.

164. The method according to claim 159, further including the step of positioning a reinforcing material between the tissue layers.

165. The method according to claim 159, wherein the forming step causes tissue adhesions to form between the tissue layers.

166. The method according to claim 159, further including the step of promoting adhesion between the tissue layers.

167. The method according to claim 164, wherein the promoting step includes positioning an in-growth promoting material between the tissue layers.

168. The method according to claim 167, wherein the in-growth promoting material includes structural features for receiving tissue growth.

169. The method according to claim 167, wherein the in-growth promoting material comprises an in-growth promoting substance.

170. The method according to claim 165, wherein the passing step is performed after adhesions have formed between the tissue layers.

171. The method according to claim 165, wherein the passing step is performed before adhesions have formed between the tissue layers.

172. The method according to claim 158, wherein the method includes forming a second tissue fold and creating a second perforation in the second tissue fold, and wherein the coupling step couples an implant to the second tissue fold by passing a portion of the medical device through the second perforation.

173. The method according to claim 172, wherein the step of coupling an implant to the first tissue fold and the step of coupling an implant to the second tissue fold include coupling the same implant to the first and second tissue folds.

174. The method according to claim 172, wherein the step of coupling an implant to the first tissue fold and the step of coupling an implant to the second tissue fold include coupling separate implants to the first and second tissue folds.

175. The method according to claim 172, wherein the method includes forming second and third tissue folds and second and third perforations in the second and third tissue folds respectively, and wherein the coupling step includes passing an implant through the first, second, and third perforations.
