8. An implantable medical device for at least partially obstructing a neck portion of a vascular aneurysm, wherein the implantable medical device is of a size and overall flexibility to lodge at the neck portion of the vascular aneurysm and is deliverable through a tubular delivery device, the device comprising:
-
an occlusion subassembly comprising a base section and at least one lateral protrusion fixedly attached to the base section, wherein said at least one lateral protrusion is a plurality of loop members that extend radially from the base section and include a plurality of ends that are fixedly attached to said base section;
a therapeutic agent disposed upon at least one portion of the occlusion subassembly, wherein the therapeutic agent is a bioactive material, and wherein the bioactive material is a biologically absorbable suture material that encourages cell growth. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. An implantable retainer bridge, deliverable via a vascular catheter, of a size and overall flexibility to lodge at the neck of a vascular aneurysm, and suitable for retaining at least a vaso-occlusive device in a vascular aneurysm, comprising:
-
an elongated tubular delivery member having a proximal end and a distal end;
a vaso-occlusion device retainer subassembly comprising a base section, a plurality of loops having ends fixedly attached to said base section, said retainer subassembly having a first delivery shape when within said vascular catheter and a second deployed shape, different than the first delivery shape, when said retainer subassembly is not retained within said vascular catheter, said base section being positioned coaxially about and adjacent to the distal end of said elongate tubular delivery member, said base section being detachable from said elongated tubular member upon severance of an electrolytically severable joint;
said electrolytically severable joint being between said retainer subassembly and said elongated tubular delivery member, severable upon application of a suitable current to said joint; and
a therapeutic agent disposed upon at least one portion of at least one of the plurality of loops, wherein the therapeutic agent is a bioactive material, and wherein the bioactive material is a biologically absorbable suture material that encourages cell growth. - View Dependent Claims (21, 22, 23)

24. An implantable retainer, deliverable via an elongate tubular delivery device, for retaining at least a vaso-occlusive device in a vascular aneurysm, comprising:
-
a core wire having a proximal end and a distal end;
a joint extending between the distal end of the core wire and at least one array element, said joint being electrolytically severable upon application of a suitable current to said joint, said joint being comparatively more susceptible to electrolytic severability than said core wire and said at least one array element;
a retainer assembly comprising said at least one array element, said retainer assembly having a first delivery shape when retained within said elongate tubular delivery device and a second deployed shape, different than the first delivery shape, when said retainer assembly is not retained within said tubular delivery device, said at least one array element extending outwardly from said joint in said second deployed shape, and wherein after an electrolytic severance from said core wire, said retainer assembly includes a residual joint; and
bioactive material disposed upon at least one portion of at least one array element, wherein the therapeutic agent is a bioactive material, and wherein the bioactive material is a biologically absorbable material. - View Dependent Claims (25, 26, 27)
