Right coronary catheter
First Claim
1. 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.

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.
