ABSTRACT:
A distal tip for securing a plurality of spline elements to form a catheter basket assembly is formed from a flexible, resilient material, such as silicone. The distal tip includes a plurality of passages extending radially therethrough for receiving individual spline elements, the passages intersecting an axis and spaced apart circumferentially and axially from one another with respect to the axis. The distal tip may be formed by wrapping the spline elements around a tool, such that their midpoints intersect within a cavity in the tool. An uncured material is introduced into the cavity, and then cured to form the plurality of spline passages directly around the spline elements. During use, the spline elements may be directed between contracted and expanded conditions, with the distal tip resiliently yielding and thereby minimizing stress in the spline elements.
