Publication number: 20220313267Abstract: An implant can be placed into an aneurysm sac that includes a bioabsorbable coiled fiber having a coiled shape similar to a metallic embolic coil. The implant can have an absorption rate long enough so that the aneurysm can become sufficiently occluded and sufficiently healed as the implant is absorbed. The implant can include crossing microfibers to initiate thrombosis within the aneurysm and/or a stretch-resistant member extending through a lumen of the coiled shape to inhibit elongation of the coiled shape. The crossing microfibers can be attached to the coiled fiber by friction fit between coil windings, heat bonding to the coiled fiber, and/or securement to the stretch-resistant member. The coiled fiber, crossing microfibers, and stretch-resistant member can have rates of absorption that differ to promote an accelerated sequence of occlusion and healing of the aneurysm.Type: ApplicationFiled: March 31, 2021Publication date: October 6, 2022Applicant: DePuy Synthes Products, Inc.Inventor: Robert SLAZAS
