Method of Attaching a Mesh to a Coated Loop Member of a Surgical Snare Device

This specification describes methods 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, placing the mesh over 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 methods include 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.
