Abstract:
1. An implantable biodegradable device to promote the healing of a laparoscopic wound, the device comprising: an inner button having a spherical convex contacting surface and a back surface, the contacting surface having a first longer diameter and a first shorter diameter whereby the first longer diameter is sufficiently smaller than the wound opening to enable one to insert it with the contacting surface perpendicular to the opening, and sufficiently large enough to cover a sufficient amount of the wound to promote healing; a cylindrical segment with an outer surface, an inner surface, a contacting end and an opposing end, the outer surface having a radial detent groove on the contacting end and the inner surface having inner threads on the opposing end, the cylindrical segment attachable to the center of the contacting surface of the inner button at the contacting end; and an outer button, having a second longer diameter, second shorter diameter, a spherically convex contacting surface and a back surface, the outer button having a hole through its center to allow the cylindrical segment to pass through the hole, the second longer diameter at least as long as the first longer diameter but sufficiently smaller than the wound opening to enable one to insert it with the contacting surface perpendicular to the opening; a spring retainment feature, consisting of a plurality of strips arranged in a radial fashion, the spring retainment feature attachable to the center of the contacting surface of the outer button at the base of the strips, the strips having ends bent radially inward, the spring retainment feature having sufficient radius that it slides over the cylindrical segment, the ends of the strips bent such that they can contact the detent groove and will resist movement.
