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.

Claims8

Dependent claims

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 defining a curving sidewall and a central point attached to the distal end of said expandable anchoring element, said restraining framework having apertures within said framework sidewall to permit the passage of embolic devices and adapted to be positioned with an aneurysm;
wherein the restraining framework takes the form of a wire basket of a hemispherical configuration;
said expandable anchoring element being capable of providing a radial force on the vessel to prevent movement and migration of said framework;
said expandable anchoring element permitting passage of embolic devices to and through said apertures within the sidewall of said framework;
and
at least one embolic device in contact with and retained by said framework to thereby hold the embolic device within the aneurysm.
