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

Benefits of technology

[0012] It is therefore an object of the present invention to improve the percutaneous transradial approach to catheterization by proposing a catheter specific to transradial catheterization. It is a further object of the invention to provide a catheter for transradial approach which avoids the drawbacks o

Problems solved by technology

Accordingly, the preshaped guiding catheters should have a configuration of lines, curves and/or angles which precisely match the environmental context in which they will have to be used and it is therefore practically impossible to simply foresee the effects of changes made to the catheter shape.
So far, the

Embodiment Construction

[0022] The catheter shown in FIGS. 1 and 2 is tubular and comprises a distal bridge shaped portion 1 having a distal arch 2 defining a primary curve 3, a top 4 defining a secondary curve 5, and a proximal arch 6 defining a tertiary curve 7. The proximal arch 6 is connected to a distal end 8 of a straight shaft 9 the proximal end of which is fitted with the usual handling connector (not shown). The shaft 9 is stiff and the bridge shaped portion 1 has a flexibility extending at least up to and including the primary curve 3 and a stiffness extending at least up to and including the tertiary curve 7.

[0023] More specifically, the bridge shaped portion 1 comprises a first distal straight portion 10, a first primary curve 3 extending from said first straight portion 10, which primary curve has a concavity oriented towards the proximal end 11 of the bridge shaped portion 1. A second straight portion 12 extends from primary curve 3 and is inclined towards the proximal end 11 of the bridge s...

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.

No. 6,620,150, which is a continuation of U.S. application Ser. No. 09 / 356,830, filed Jul. 19, 1999, now U.S. Pat. No. 6,273,881, which is a continuation of U.S. application Ser. No. 08 / 899,083, filed Jul. 23, 1997, which is a continuation of U.S. application Ser. No. 08 / 560,251, filed Nov. 21, 1995.BACKGROUND OF THE INVENTION [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 ...
