Abstract
A catheter includes a tubular body, a ring member, and at least one elongate member. The tubular body has a distal region. The ring member encircles at least a portion of the circumference of the tubular member. The one elongate member has a proximal end and a distal end, the distal end of the elongate member being coupled to the distal region of the tubular body and the proximal end being attached to the ring member. Forming a loop in a distal end of a catheter includes pulling a ring that encircles at least a portion of the circumference of the catheter. The ring is attached to a proximal end of an elongate member, a distal end of the elongate member is attached to a distal end of the catheter, and the elongate member is positioned along the outside surface of the catheter.
