MEDICAL CANNULAE, DELIVERY SYSTEMS AND METHODS

摘要

The disclosure relates to cannulae, delivery systems, methods of mak¬ ing cannulae, and methods of making delivery systems. A delivery system comprises an elongate outer tubular member defining an outer tubular mem¬ ber lumen, a cannula having a circumferential wall extending between a prox¬ imal end and a distal end and defining an interior lumen, and an intraluminal medical device disposed within the outer tubular member lumen distal to the cannula and not about the cannula. A pattern of openings arranged in an in¬ terrupted spiral extends circumferentially along the cannula.
