Abstract
An adhesion barrier is comprised of, consists of, or consists essentially of a sheet having a top surface and a bottom surface. The sheet includes either (i) interconnected links or (ii) interconnected, vertically aligned, partitions. The links form pores or the partitions form pores, with the pores extending from the top surface through the bottom surface. The sheet is comprised of, consists of, or consists essentially of a flexible or elastic polymer.
Claims25
An adhesion barrier comprising a sheet having a top surface and a bottom surface,
- said sheet comprising interconnected, vertically aligned, partitions,
- said partitions forming pores, said pores extending from said top surface through said bottom surface,
- wherein said sheet is comprised of a flexible or elastic polymer,
- wherein said sheet is produced from a light polymerizable resin by an additive manufacturing process,
- wherein said sheet has a thickness of at least 1 millimeter,
- wherein said flexible or elastic polymer comprises a bioresorbable polyester, and wherein:
- said sheet has a length (X) dimension, a width (Y) dimension, and a depth (or vertical) (Z) dimension, said length and width dimensions together comprising lateral dimensions;
- and
- said sheet is stiffer in said vertical dimension than in said lateral dimensions.
