Patent ID: 8771294

Claim:
An occlusion device for occluding a cerebral aneurysm comprising a member comprising a porous, explosively reticulated, elastomeric matrix, wherein the porous, explosively reticulated elastomeric matrix has at least partially removed cell walls between adjoining pores of the porous, explosively reticulated elastomeric matrix, and at least one longitudinally extending reinforcing filament, wherein the porous, explosively reticulated elastomeric matrix comprises a cross-linked, biodurable, reticulated, resilient elastomeric matrix comprising interconnected and intercommunicating networks of pores, channels, and voids, configured to permit ingrowth of tissue into the interconnected and intercommunicating networks of pores, channels, and voids, wherein the elastomeric matrix comprises polycarbonate polyurethane-urea, polycarbonate polyurea-urethane, polycarbonate polyurethane, polycarbonate polysiloxane polyurethane, or polysiloxane polyurethane, or a copolymers thereof, or any mixture thereof, wherein the elastomeric matrix is at least partially hydrophobic, wherein the device is configured to assume a non-linear shape that conformally fills a targeted vascular site, and wherein the device is configured to prevent recanalization and migration after tissue ingrowth has taken place in the reticulated matrix.
