Catheter for percutaneous transradial approach

a tubular catheter and percutaneous transradial technology, which is applied in the direction of catheters, guide wires, guide needles, etc., can solve the problems of relative lack of backup and coaxiality with the artery, the inability to precisely predict the effects of changes in the shape of the catheter, and the inability to manufacture specific catheters for this technique, etc., to avoid unnecessary costs, improve the percutaneous transradial approach to catheterization, and avoid unnecessary costs

Abstract

A preshaped tubular catheter for percutaneous transradial approach to catheterization, comprises a distal bridge shaped portion having a distal arch defining a primary curve, a top defining a secondary curve, and a proximal arch defining a tertiary curve. The proximal arch is connected to a straight shaft. The shaft is stiff and the bridge shaped portion has a flexibility extending at least up to and including the primary curve and a stiffness extending at least up to and including the tertiary curve.

[0002] This invention relates to preshaped tubular catheters for percutaneous transradial approach to catheterization.

[0003] Preshaped catheters are commonly used for medical procedures such as diagnosis or such as coronary angioplasty or coronary stent implantation in which they serve to guide other catheters such as pressure measuring or balloon ...
