ABSTRACT:
An apparatus for removing and replacing a coronary balloon catheter during coronary angioplasty comprises a double catheter. A guiding catheter is inserted into the opening of a coronary artery. An auxiliary balloon catheter is disposed axially inside the guiding catheter, and is secured along the side wall of the guiding catheter. A balloon is secured near the distal end of the auxiliary balloon catheter.
A method for removing and replacing a coronary balloon catheter during coronary angioplasty comprises the steps of inserting a guiding catheter containing an auxiliary balloon catheter in the opening of a coronary artery; inserting a first coronary balloon catheter through the guiding catheter into the coronary artery; withdrawing the first coronary balloon catheter from the coronary artery into the guiding catheter until the first coronary balloon catheter is proximal to the balloon on the auxiliary balloon catheter; inflating the balloon on the auxiliary balloon catheter; removing the first coronary balloon catheter; and inserting a second coronary balloon catheter through the guiding catheter into the coronary artery.
