IMPLANTABLE EMBOLIC SCAFFOLDS THAT PROMOTE HEALING

摘要

Implant devices and structures that reduce inflammation and promote healing of the area of implant. Specifically, the use of shape memory open cell biocompatible polymer foams for implants that assist in and promote healing and especially in filling and sealing aneurisms.

主权项

1. An apparatus comprising:
a vascular implant comprising a shape memory polyurethane polymer foam scaffold having cell membranes opened by at least one of physical and chemical reticulation; wherein (a) the polymer foam includes membranes that are each partially reticulated so that a single membrane between two adjacent cells is partially removed yet still remains, (b) the polymer foam includes a first cell having a first percentage of its membrane reticulated and a second cell having a second percentage of its membrane reticulated, and (c) the second percentage is at least 50% and less than 100%.
