SELF-VENTING ELASTOMERIC BALLOON CATHETER

摘要

A balloon catheter comprises a catheter body having an elastomeric balloon at its distal end. The balloon has a small diameter vent hole disposed near its distal end. The balloon catheter may be prepared by flushing an inflation lumen and the interior of the balloon with a suitable liquid flushing medium, where the balloon is inflated by the flushing medium beginning at its proximal end and moving toward its distal end.
