ENHANCED BALLOON DILATATION SYSTEM

摘要

A balloon dilatation system (1) is comprised of an elongated flexible advancement member (5) which terminates in a tubular tracking member (7) slidable over a guidewire (9). An inflatable balloon (10) has proximal (12), and distal ends (14), the proximal end (12) communicating with an inflation channel (15), and the distal end (14) attaching to the tracking member (7). The balloon portion (10) is coextensive with but not attached to the advancement member (5).
