Abstract

A catheter for use with a medical infusion or other fluid system. The catheter may include a flexible elongate tubular core that is resistant to radial collapse, and a separate tubular tip member forming the catheter distal tip. The catheter may further include a flexible, e.g., elastomeric, jacket that surrounds at least a portion of the tubular core. The jacket may have a radial compliance that is greater than that of the tubular core. The jacket may further define an outer diameter that is about 4 to about 6 times greater than an outer diameter of the core.
