Abstract

There is provided herein, a method of attaching a mesh to a loop member, which includes covering a wire with a layer, manipulating the wire along with the layer to form the loop member, wherein the loop member has a shape, placing the mesh over the loop member, wherein portions of the mesh extend beyond a circumference of the loop member, transferring heat to the layer to cause it to partially melt and become tacky, allowing the mesh to fuse with the tacky layer and form a secure bond on cooling, and trimming portions of the mesh extending beyond the circumference of the loop member. A retrieval device formed by the method includes the loop member and attached mesh positioned and longitudinally movable within a tubular sheath. The loop member and mesh are deployed to capture a target object and partially retracted for removal of the object.
