摘要
A retrieval snare for entrapping and retaining a foreign object located in a body and a method for manufacturing of the snare are provided. The snare comprises a structure having a proximal portion and a distal portion and includes a plurality of filaments. The filaments extend from an end of the proximal portion towards the distal portion and return to the end of the proximal portion to form a plurality of loops. The loops are not interconnected at the distal portion, but each side of each loop are connected to a side of an adjacent loop in the proximal portion at more than one point, thereby providing structural rigidity and dilatation ability to the snare.
