Abstract
A method of extracting an implant from a vessel includes inserting an extraction device into the vessel. The extraction device includes a hollow body having a cylindrical portion and a bellowed portion. An inner diameter of the bellowed portion increases toward an end of the hollow body. The method also includes sliding the extraction device over an outer surface of the implant such that the hollow body slides between a vessel wall and the implant to move the implant from a deployed position to a non-deployed position within the hollow body. The method can also include removing the extraction device and the implant from the vessel.
