PC 7170 BAIL-OUT CATHETER Abstract A catheter for maintaining the patency of a blood vessel damaged during the course of angiography or angioplasty procedures comprising a toroidal coil whose adjacent turns are tightly wound and in contact with one another over a majority of the length thereof but which are separated from one another over a predeter- mined longitudinal dimension near the distal end thereof. The tightly wound touching coils may be covered with a Teflon coating and when the catheter must be used to maintain patency in a coronary artery, it is advanced along the guide wire of an angiography or angioplasty catheter until the open turn portion of the bail-out catheter bridges the site of the damaged vessel. After the angiographic or angioplasty catheter and its guide wire are removed, the bail-out catheter remains in position so that blood can flow through the open turns of that catheter and beyond until such time as surgical repair can be made.
