Method and apparatus for retrieving an embolized implant

Abstract

A retrieval portion is attached to an implantable device to facilitate retrieval of the implantable device in the unlikely event of embolization. The retrieval portion may comprise one or more loops, or a plurality of extensions. Methods of retrieving an implantable device are disclosed. Various adapters are disclosed for use with a conventional snare for grasping an implantable device.

What is claimed is: 
     
         1 . An apparatus for facilitating removal of an implantable device from an opening within a patient, comprising: a support structure having a proximal end and a distal end, the support structure being expandable to an enlarged configuration and collapsible to a reduced configuration; and a retrieval portion extending distally from the distal end of the support structure, the retrieval portion comprising at least one loop.
