Balloon catheter and method of use

摘要

A balloon catheter includes an elongate support member defining first and second openings therein, open proximal and distal ends, and an axial lumen; and a balloon disposed on the elongate support member, the balloon defining a balloon interior through which the support member extends, where the balloon interior has a proximal end region, a middle region, and a distal end region, with the first opening located in the middle region, and the second opening located in the distal end region, such that the support member lumen is in communication with the balloon interior through each of the first and second openings, and such that a pressurized liquid introduced through the open proximal end of the support member will enter the balloon interior through the first opening, and subsequently exit the balloon interior through the second opening, back into the lumen, and out the open distal end of the support member.

1. A balloon catheter, comprising:
an elongate support member comprising a tubular wall defining first and second openings therein, open proximal and distal ends, and an axial lumen in communication with the first and second openings and the open proximal and distal ends; and a balloon disposed on the elongate support member, the balloon defining a balloon interior through which the elongate support member extends, wherein the balloon interior has a proximal end region, a middle region, and a distal end region, with the first opening located in the middle region, and the second opening located in the distal end region, such that the support member lumen is in communication with the balloon interior through each of the first and second openings, and such that a pressurized liquid introduced through the open proximal end of the support member will enter the balloon interior through the first opening, and subsequently exit the balloon interior through the second opening, back into the lumen, and out the open distal end of the support member, and wherein a radipaque marker is disposed on the elongate support member in the distal end region of the balloon interior, proximal of the second opening.
