Claims
- 1. A catheter assembly for performing intraluminal ultrasound procedures within a patient's coronary artery, comprising:
a) guiding catheter having proximal and distal ends which is adapted to be disposed within a patient's cardiovascular system with the distal end seated within an ostium of the patient's coronary artery and the proximal end extending out of the patient; b) a guidewire with proximal and distal ends which is adapted to be disposed within the guiding catheter with the distal end of the guidewire extending out the distal end of the guiding catheter into the coronary artery of the patient and the proximal end of the guidewire extending out the proximal end of the guiding catheter which extends out of the patient; and c) an elongated ultrasound imaging catheter having an elongated catheter body with a proximal end adapted to extend out of the patient, a distal end, a first elongated inner lumen within the catheter body extending from the proximal end to the distal end, and a second much shorter inner lumen which is fixed with respect to said catheter body and which is defined at least in part by a tubular member extending substantially within the catheter body which is adapted to slideably receive the guidewire, the second inner lumen having a distal port located in the distal end of the catheter body and a proximal port extending through the catheter body.
- 2. The catheter assembly of claim 1, wherein the proximal port of the imaging catheter is located at least 10 centimeters from the distal end of the catheter body.
- 3. The catheter assembly of claim 1, wherein the proximal port of the imaging catheter is located a substantial distance from the proximal end of the catheter body.
- 4. The catheter assembly of claim 1, wherein the proximal port of the imaging catheter is located in a position relative to the distal end of the catheter body that allows the proximal guidewire port to remain within the guiding catheter when the ultrasound imaging catheter is advanced into the patient's artery
- 5. A catheter assembly for performing intraluminal ultrasound procedures within a patient's cardiovascular system, comprising:
a) guiding catheter having proximal and distal ends, the distal end seated within an ostium of an artery and the proximal end extending out of the patient; b) a guidewire with proximal and distal ends slideably insertable in the guiding catheter, the distal end of the guidewire extending out the distal end of the guiding catheter into the artery and the proximal end of the guidewire extending out the proximal end of the guiding catheter; and c) an elongated ultrasound imaging catheter having an elongated catheter body with a proximal end, a distal end, a first elongated inner lumen within the catheter body extending from the proximal end to the distal end, and a second shorter inner lumen which is fixed with respect to said catheter body and which is defined at least in part by a tubular member extending substantially within the catheter body which is adapted to slideably receive the guidewire, the second inner lumen having a distal port located in the distal end of the catheter body and a proximal port extending through the catheter body
- 6. The catheter assembly of claim 5, wherein the proximal port of the imaging catheter is located at least 10 centimeters from the distal end of the catheter body.
- 7. The catheter assembly of claim 5, wherein the proximal port of the imaging catheter is located a substantial distance from the proximal end of the catheter body.
- 8. The catheter assembly of claim 5, wherein the artery is the coronary artery.
- 9. The catheter assembly of claim 5, wherein the proximal port of the imaging catheter is located a sufficient distance from the distal end of the catheter body to allow the proximal guidewire port to remain within the guiding catheter when the ultrasound imaging catheter is advanced into the patient's artery.
