Abstract
A guiding catheter exchange device allows the exchange of a coronary guiding catheter while the coronary guide wire is left in place across an obstruction in the coronary artery. In performing percutaneous transluminal coronary angioplasty, a guiding catheter is placed selectively into either the right or left coronary artery. The guide wire is advanced down the coronary artery and across the obstruction. The exchange device of the present invention allows the guiding catheter to be exchanged and while the wire is still in position across the obstruction. The exchange device has a short bore at its distal end portion which allows the exchange device to be routed into the patient's artery upon the coronary guide wire. The exchange device then provides adequate structure and support for exchanging different size guiding catheters.
