Abstract
A reduced size IAB catheter system comprising an IAB catheter disposed within a tube serving both as a insertion sheath and as a reinforcement tube. The tube is preferably disposed about the entire catheter up to the balloon membrane. The catheter remains disposed within the tube during therapy.
Claims29
An intra-aortic balloon catheter comprising an inner tube, a tip, and an outer tube, said inner tube being connected on a distal end to a proximal end of a balloon membrane, a distal end of the balloon membrane being connected to the tip, said outer tube being at least partially disposed about the inner tube during inflation and deflation of the balloon membrane and having a length that is shorter but within 4 inches (10 cm) of the length of the inner tube, said inner tube defining a lumen having a valveless communication with an area enveloped by the balloon membrane.
An intra-aortic balloon catheter comprising an inner tube, a tip, and an outer tube, said inner tube being connected on a distal end to a proximal end of a balloon membrane, a distal end of the balloon membrane being connected to a tip, said outer tube being at least partially disposed about the inner tube during inflation and deflation of the balloon membrane and having a length that is shorter but within 4 inches (10 cm) of the length of the inner tube, a proximal end of the inner tube terminates in a connector which is connectable to a connector on a proximal end of the outer tube, a proximal end of the inner tube terminates in a connector which is connectable to a connector on a proximal end of the outer tube.
An intra-aortic balloon catheter comprising an inner tube, a first outer tube, a second outer tube, a balloon membrane, and a tip, a distal end of the first outer tube is connected to a proximal end of the balloon membrane, a distal end of the balloon membrane is connected to the tip, the inner tube is disposed within an outer surface of the first outer tube, the second outer tube being at least partially disposed about the first outer tube during inflation and deflation of the balloon membrane and having a length that is shorter but within 4 inches (10 cm) of the length of the first outer tube.
A method for inserting and operating an intra-aortic balloon catheter comprising an inner tube, a tip, and an outer tube, said inner tube being connected on a distal end to a proximal end of a balloon membrane, a distal end of the balloon membrane being connected to the tip, said method comprising the steps of:
- (a) inserting a guide wire into a blood vessel of a patient;
- (b) advancing the outer tube over the guide wire into the blood vessel, a proximal portion of the outer tube remaining outside the blood vessel;
- (c) removing the guide wire from the blood vessel;
- (d) advancing the inner tube through the outer tube such that the balloon membrane projects from a distal end of the outer tube a distance no greater than approximately 4 inches (10 cm), a proximal portion of the inner tube remains outside the blood vessel;
- and
- (e) initiating inflation and deflation of the balloon membrane while the outer tube is disposed about the inner tube.
