Bioactive components for incorporation with vaso-occlusive members
View Patent ↗A vaso-occlusive device is disclosed. The device includes a vaso-occlusive member having a coating disposed thereon. In accordance with one embodiment, the coating comprises a polyacrylic material. In accordance with another embodiment, the coating comprises a polyvinyl alcohol-based material. In accordance with other embodiments, various other materials and coatings are applied to at least a portion of a vaso-occlusive device.
1. An implantable medical device for at least partially obstructing a neck portion of a vascular aneurysm, comprising:
an occlusion subassembly comprising a central member and a loop of wire having first and second ends connected to the central member, said loop of wire and the central member being of a size and overall flexibility to lodge at the neck portion of the vascular aneurysm; and a coil attached to and radially disposed about a portion of the loop of wire; and
the occlusion subassembly further comprises a fibrous woven tubular member extending coaxially over at least a portion of the coil, the tubular member comprising a material for encouraging a cellular response.
2. The implantable medical device of claim 1 , wherein the tubular member comprises a biodegradable material.
3. The implantable medical device of claims 1 , wherein the tubular member comprises a polymeric material.
4. The implantable medical device of claim 1 , wherein the tubular member comprises polyglycolic acid.
5. The implantable medical device of claim 1 , wherein the tubular member comprises polylactic acid.
6. The implantable medical device of claim 1 , wherein the tubular member comprises a mixture of polyglycolic acid and polylactic acid.
7. The implantable medical device of claim 1 , wherein the tubular member comprises a copolymer of polyglycolic acid and polylactic acid.
8. The implantable medical device of claim 1 , wherein the tubular member is braided.
9. The implantable medical device of claim 1 , further comprising a marker coil radially disposed about a portion of the loop of wire.
10. An implantable medical device for at least partially obstructing a neck portion of a vascular aneurysm, comprising:
an occlusion subassembly comprising a central member and a loop of wire having first and second ends connected to the central member, said loop of wire and the central member being of a size and overall flexibility to lodge at the neck portion of the vascular aneurysm; and a coil attached to and radially disposed about a portion of the loop of wire; and
the occlusion subassembly further comprises a fibrous woven tubular member extending coaxially over at least a portion of the coil, the tubular member comprising a biodegradable material for encouraging a cellular response.
11. The implantable medical device of claim 10 , wherein the tubular member comprises a polymeric material.
12. The implantable medical device of claim 10 , wherein the tubular member comprises polyglycolic acid.
13. The implantable medical device of claim 10 , wherein the tubular member comprises polylactic acid.
14. The implantable medical device of claim 10 , wherein the tubular member comprises a mixture of polyglycolic acid and polylactic acid.
15. The implantable medical device of claim 10 , wherein the tubular member comprises a copolymer of polyglycolic acid and polylactic acid.
16. The implantable medical device of claim 10 , wherein the tubular member is braided.
17. The implantable medical device of claim 10 , further comprising a marker coil radially disposed about a portion of the loop of wire.
