Abstract
Abstract A right coronary catheter for use in selective coronary arteriography using a femoral artery approach. The catheter is preformed to permit insertion of the catheter tip into the orifice of the right coronary artery without substantial rotation of the catheter body. In addition, the configuration of the catheter renders it adaptable to most coronary anatomies thereby avoiding the need to estimate and preselect a catheter geometry for each individual patient variation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
125 words
A preformed right coronary catheter for use in coronary arteriography of the human right coronary artery using a femoral artery approach, comprising a primary curve, a secondary curve, a tip portion, a substantially straight central body portion and a substantially straight rear body portion, said primary curve being disposed between said tip portion and said central body portion and defining a first angle therebetween of substantially less than 90°, said secondary curve being disposed between said central body portion and said rear body portion and defining a second angle therebetween of about 60°, this geometry of said catheter enabling direct engagement and insertion of said catheter tip into said right coronary artery by means of a femoral artery approach without the need for catheter rotation.
Claim 2
Dependent Claim
125 words
A preformed right coronary catheter for use in coronary arteriography of the human right coronary artery using a femoral artery approach, comprising a primary curve, a secondary curve, a tip portion, a substantially straight central body portion and a substantially straight rear body portion, said primary curve being disposed between said tip portion and said central body portion and defining a first angle therebetween of substantially less than 90°, said secondary curve being disposed between said central body portion and said rear body portion and defining a second angle therebetween of about 60°, this geometry of said catheter enabling direct engagement and insertion of said catheter tip into said right coronary artery by means of a femoral artery approach without the need for catheter rotation.
Claim 3
Dependent Claim
51 words
A preformed right coronary catheter according to claim 1 wherein said first angle is about 70°, and said substantially straight central body portion is about 2.increment. long such that said catheter conforms to substantially all anatomical variations in the size and configuration of the human coronary arch and right coronary artery.
Claim 4
Dependent Claim
19 words
A preformed right coronary catheter according to claim 1 wherein said catheter is comprised of a low temperature thermoplastic.
Claim 5
Dependent Claim
16 words
A preformed right coronary catheter according to claim 3 wherein said low temperature thermoplastic is polyurethane.
