Abstract
Exchange catheters which allow for the removal of a standard guidewire and replacement with a guidewire or catheter bearing an occlusive device during percutaneous transluminal angioplasty or related procedures. The elongate catheters have at least one lumen, and are preferably provided with a slit approximately 3-20 mm in length at the distal end of the lumen to allow the catheter to expand to accommodate the passage of the occlusive device while still maintaining a low profile. The catheters can also be used to provide aspiration and/or delivery of fluid.
