Abstract:
An embodiment includes a system comprising: a substrate of a medical device; an un-foamed polyurethane coating directly contacting the substrate and fixedly attached to the substrate; a thermoset polyurethane shape memory polymer (SMP) foam, having first and second states, which directly contacts the polyurethane coating and fixedly attaches to the polyurethane coating; wherein the polyurethane coating fixedly attaches the SMP foam to the substrate. Other embodiments are described herein.

Claim (Index 18):
A method comprising:\n coating a substrate of a medical device with an un-foamed polyurethane coating that directly contacts the substrate and fixedly attaches to the substrate; forming a mixture by combining N,N,N\u2032,N\u2032-tetrakis (2-hydroxypropyl) ethylenediamine (HPED), and at least two members selected from the group consisting of: triethanolamine (TEA), and hexamethylene diisocyanate (HDI), trimethylhexamethylenediamine (TMHDI), Glycerol, and pentanediol; locating the polyurethane coated substrate adjacent the mixture; foaming the mixture into a monolithic foam that expands towards the polyurethane coated substrate, directly contacts the polyurethane coated substrate, substantially surrounds the polyurethane coated substrate, and fixedly attaches to the polyurethane coated substrate; separating the monolithic foam into a first portion of the foam contacting the polyurethane coated substrate and a remaining bulk portion of the foam; and forming the first portion of the foam into a primary state and a programmed state to form a shape memory polymer (SMP) foam.
