Abstract
A vascular occlusion device that includes a central support member that has at least one mesh embolic ribbon extending outwardly from the central support member in the generally radial direction is provided. The mesh embolic ribbon has a collapsed and an expanded configuration.
Claims32
An occlusion device comprising:
- a central support member having a length and a cross-sectional width, the central support member is wound into a helically shaped coil;
- and
- at least one embolic ribbon extending from the central support member in a generally radial direction, said at least one embolic ribbon also extending at least partially along the length of the central support member, wherein the at least one embolic ribbon is shaped into a spiral pattern around the central support member.
A vascular occlusion device, comprising:
- an embolic coil formed from a support wire of a selected length wound into a helical shape;
- and
- a pair of opposed mesh embolic ribbons located on the support wire, said pair of mesh embolic ribbons extending along at least a portion of the length of the support wire and extending outwardly from the support wire, wherein the mesh embolic ribbons are shaped into a spiral around the support wire.
An occlusion device, comprising:an embolic mesh ribbon, said ribbon twisted into a spiral-like pattern as a spiraled ribbon length;
- and said spiraled ribbon length is helically coiled into the occlusion device.
A method of making an occlusion device, comprising;
- winding a support wire around a mandrel in a helical fashion to form adjacent coils;
- coating the support wire and the mandrel with a thin metal film;
- cutting the thin metal film between the adjacent coils to create at least one embolic ribbon extending from the support wire;
- perforating the pair of opposed embolic ribbons;
- separating the support wire and thin metal film from the mandrel;
- shaping the support wire and the pair of opposed embolic ribbons into a desired shape;
- twisting the support wire relative to a longitudinal axis of the support wire to form the at least one embolic ribbon into a spiral shape;
- and
- winding the support wire into a helical shape.
