<p>An inflatable working element is provided for a catheter device, the catheter device having an elongated flexible tubular shaft containing an inflation lumen therethrough. The working element includes a hollow bladder device selectively inflatable from a first condition to an expanded second condition. The bladder device defines an inflation passage extending from a proximal end opening to a distal end opening thereof. The proximal end opening is configured to cooperate with a distal portion of the elongated shaft such the inflation passage is in access communication with the shaft inflation lumen. The bladder device further includes an inverted tubular arm member configured to be disposed in the inflation passage. The tubular arm member includes a first end port accessible through the proximal end opening of the bladder device and an opposed second end port integrally formed with, and terminating at, a sidewall of the bladder device.</p> |
