Abstract
Reaction product of an aliphatic organic diisocyanate, a high molecular weight polyether polyol (poly tetra methylene ether glycol) and 1,4 butane diol. The resulting polymers have thromboresistant properties, a long flexural life and are extrudable. The polyurethane polymer is ideal for forming transvenous cardiac pacemaker leads, blood bags, intravenous and intra-arterial catheters and tubing, and other shaped devices which must be formed of a blood compatible material.
