Abstract

A tube or ring-shaped, elastic cuff is used as a antimicrobial fitting for medical catheters. The fitting is manufactured from organic silicon/polyurethane elastomer including an antimicrobial agent. The fitting is annularly disposed on a catheter and held in place by radial tension. The fitting has very high tensile strength and resistance to tearing and preferably has a wall thickness of about 0.1 mm; may be cut into segments of 2 to 10 cm long; and can be drawn onto a catheter as individual segments.
