Abstract
Disclosed herein are detachment mechanisms for vaso-occlusive devices that allow for rapid operator-controlled release of the vaso-occlusive device into the selected site. Also disclosed are vaso-occlusive assemblies comprising these detachment mechanisms and methods of using these detachment mechanisms and vaso-occlusive assemblies.
Claims19
An assembly, comprising:
- an implantable device that includes a structure having a plurality of adjacent windings extending therefrom;
- and
- a detachment mechanism that includes a first electroactive polymer and a second electroactive polymer each configured to reversibly engage the structure between two of the adjacent windings;
- wherein the first and second electroactive polymers move from an expanded configuration to an unexpanded configuration such that the first and second electroactive polymers overlap each other, upon application of heat or electrical energy, to release the implantable device.

A method of delivering an implantable device, comprising:
- introducing an assembly into a lumen of a patient, the assembly comprising:
- an implantable device that includes a structure having a plurality of adjacent windings extending therefrom;
- and
- a detachment mechanism that includes a first electroactive polymer and a second electroactive polymer each configured to reversibly engage the structure between two of the adjacent windings;
- wherein the first and second electroactive polymers move from an expanded configuration to an unexpanded configuration such that the first and second electroactive polymers overlap each other, upon application of heat or electrical energy, to release the implantable device;
- and
- applying heat or electrical energy to the first and second electroactive polymers to release the implantable device.
