Abstract:
A preshaped tubular catheter for percutaneous transradial approach to catheterization, comprising:a distal bridge portion having a distal portion defining a primary curve, a top defining a secondary curve, and a proximal portion defining a tertiary curve, wherein said proximal portion is connected to a distal end of a generally straight shaft, and wherein said bridge portion has a more flexible portion extending at least up to the primary curve and a portion less flexible than the flexible portion extending at least up to said tertiary curve; means for advancing the bridge portion through either a radial artery or a femoral artery to a region adjacent a coronary artery of a patient; wherein the bridge portion includes a generally straight distal region disposed distal to the primary curve; and means for co-axially aligning the distal region within the coronary artery when the catheter is advanced through either the radial artery or the femoral artery.
