Abstract
A catheter tip that provides longitudinal flexibility, pushability and radial rigidity thereby improving deliverability is provided. The catheter tip includes a spring-like element to provide longitudinal flexibility and pushability to the catheter tip. The spring-like element may also provide radial support to the distal edge of the catheter tip. Alternatively, a radially rigid distal end may also be included distal of the spring-like element. The apparatus may be used with any interventional catheter system, but is particularly suitable for use with balloon-expandable stent systems and balloon-angioplasty systems, where flexibility of the catheter tip and minimal flaring of the distal edge of the catheter tip is desirable.
