Abstract
An apparatus and method for making an occlusion device for occluding a body vessel. The apparatus and method include providing a frame and a mandrel. The frame has a hub extending along a longitudinal axis from a proximal end to a distal end. A plurality of arcuate legs are attached to the hub and extend distally. The arcuate legs are flexible and have inner surfaces defining an inner profile in an unconstrained state. The mandrel has an outer surface corresponding to the inner profile of the occlusion device. A base layer of a biocompatible material is disposed on the outer surface of the mandrel. The frame is placed on the outer surface with the base layer between the frame and the mandrel. The frame is attached to the base layer such that the biocompatible material forms a membrane extending along and between the arcuate legs.
