Abstract
In one aspect, the present invention relates to a medical device, such as a medical electrical lead, comprising a biomaterial formed from a polymer comprising urethane groups and saturated linear polyethylene moieties wherein the saturated linear polethylene moieties have greater than 12 carbon atoms per moiety. In another aspect, the present invention relates medical devices comprising a biomaterial formed from segmented polymers or polymers having an elongation of greater than 50%. Exemplified polymers contain compounds of the formula HO—(CH2)n—OH wherein n is greater than 12.
