Abstract

A melt extruded catheter of thermoplastic elastomeric hydrophilic polyurethane synthesized from a diisocyanate, polyethyleneoxide glycol of high molecular weight and a chain extender expands to a larger lumen size when contacted with an aqueous liquid. The catheter may include an antithrombogenic agent, antiinfective agent and radiopaque agent. The hydrophilic polyurethane may be synthesized by one-shot bulk polymerization, and may be melt extruded into the catheter tubing. [CA2017951C]
