Abstract

A method and device used for treating an aneurysm of a patient. A framework for supporting one or more embolization elements is introduced into the patient'"'"'s aneurysm. A stent, connected to the framework is introduced into a vessel leading into and communicating with the aneurysm, with the stent being compressed against the inner wall of the vessel for anchoring the framework. One or more embolization elements are introduced through the framework into the aneurysm, and in this manner the framework maintains the one or more embolization elements within the aneurysm. In the illustrative embodiment, the embolization element comprises an embolic coil, the stent comprises a helical coil, and the framework and helical coil are connected so as to be introduced into the patient simultaneously.

Claims

1. An aneurysm treatment device comprising:

an expandable anchoring element exhibiting the characteristic of expanding against the walls of a vessel when unrestrained and having proximal and distal ends;

a restraining framework attached to the distal end of said expandable anchoring element, said restraining framework having aperatures within said framework to permit the passage of embolic devices and adapted to be positioned within an aneurysm; and

,

at least one embolic device in contact with and retained by said framework to thereby hold the embolic device within the aneurysm.

2. An aneurysm treatment device as defined in claim 1, wherein the embolic device comprises an embolic coil.

3. An aneurysm treatment device as defined in claim 1, including a plurality of embolic devices.

4. An aneurysm treatment device as defined in claim 3, wherein said embolic devices include a plurality of embolic coils.

5. An aneurysm treatment device as defined in claim 1, wherein the restraining framework takes the form of a wire basket of a hemispherical configuration.

6. An aneurysm treatment device as defined in claim 5, including a plurality of embolic devices.

7. An aneurysm treatment device as defined in claim 6, wherein said embolic devices include a plurality of embolic coils.
