ABSTRACT:
An intra aortic balloon pumping device comprises a pumping balloon, an attached inflation catheter, a supporting member which is disposed within and extends from the catheter into the balloon. The balloon membrane of the invention resists the formation of membrane folds in the tail section of the balloon. This characteristic of the balloon membrane is believed to result from the addition of tension to the balloon membrane. Tension may be applied to the membrane by ensuring that the portion of the support member which is disposed within the balloon is equal to the length of the outer curve of the balloon wall such that it resides on an outer curve of the wall. Alternatively, tension may be applied by extending the support member within the balloon.
