Abstract
Abstract A catheter having an elongate body including a central lumen adapted to slidably receive a therapeutic catheter. The catheter includes a soft tip adapted to lodge in the ostium of the right coronary artery. The elongate body is formed near the distal end to impinge against the wall of the aorta opposite the ostium of the coronary artery.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
A catheter comprising: an elongate catheter body having a proximal end and a distal end and having a central lumen from the proximal end to the distal end adapted to slidably receive a therapeutic catheter; a soft tip fixedly attached to the elongate catheter body adapted to removably lodge in the ostium of the coronary artery; and the elongate catheter body being bendably formed near the distal end to include a bend having a radius dimensioned to substantially continuously impinge against the wall of the aorta opposite the ostium including continuously impinging at least a portion of each of the ascending aorta, aortic arch, and descending aorta.
Claim 2
Dependent Claim
107 words
A catheter comprising: an elongate catheter body having a proximal end and a distal end and having a central lumen from the proximal end to the distal end adapted to slidably receive a therapeutic catheter; a soft tip fixedly attached to the elongate catheter body adapted to removably lodge in the ostium of the coronary artery; and the elongate catheter body being bendably formed near the distal end to include a bend having a radius dimensioned to substantially continuously impinge against the wall of the aorta opposite the ostium including continuously impinging at least a portion of each of the ascending aorta, aortic arch, and descending aorta.
Claim 3
Dependent Claim
24 words
A catheter in accordance with claim 1 , wherein the elongate catheter body includes a generally straight proximal portion and a curved distal portion.
