摘要

An elongate medical device includes a tubular member extending between a proximal end and a distal end that has a wall defining a lumen extending therethrough. The elongate medical device also includes a loop portion comprising a plurality of wires having proximal portions embedded into the wall and distal portions which are connected together to form a loop that is distal the distal end of the tubular member.
