Abstract
Some aspects of the present disclosure pertain to spherical devices that comprise a wire having a memorized shape comprising a spherical outer wire layer and a spherical inner wire layer disposed within the spherical outer wire layer. Other aspects of the disclosure pertain to methods of forming such devices, mandrels for forming such devices, and methods of using such devices.
Claims20
A spherical mandrel for producing an occlusion device having a memorized spherical shape, comprising:
- a first groove extending about the spherical mandrel for a plurality of turns;
- and
- a second groove extending about the mandrel for a plurality of turns;
- wherein the first and second grooves intersect and wherein the second groove is shallower than the first groove.
A spherical mandrel for producing an occlusion device having a memorized spherical shape, comprising:
- a spherical body;
- a first anchor disposed on the spherical body;
- a first groove having a first end at the first anchor, the first groove extending about the spherical body for a plurality of turns;
- and
- a second groove having a first end coincident with a portion of the first groove, the second groove extending about the mandrel for a plurality of turns;
- wherein the second groove is shallower than the first groove.
A method of forming an occlusion device, comprising:
- temporarily coupling a first end of a wire to an anchor of a spherical body;
- winding the wire into a first plurality of turns about the spherical body along a first groove of the spherical body;
- and
- winding the wire along into a second plurality of turns about the first plurality of turns along a second groove of the spherical body.
