Abstract: Provided are conductive films including a heparin modified polymer. The heparin modified polymer comprises heparin covalently bound to a beta-substituted monomer having a conjugated backbone that is co-polymerized to its non-functionalized pair. The heparin modified polymer on a conductive film can be manufactured by co-polymerizing a beta-substituted monomer with a non-functionalized monomer to form a polymer on a conductive film. The polymer is reacted with N,N′-Dicyclohexylcarbodiimide (DCC) and acetic acid to form an anhydride of the polymer on the conductive film. The anhydride is then reacted with heparin to form the heparin modified polymer on the conductive film. Medical devices having a coating comprising the conductive film are also described.

Abstract: Provided herein is a prefilled syringe including a syringe barrel having a proximal end and a distal end and defining a chamber, the syringe barrel having an opening at the proximal end. The prefilled syringe also includes a plunger assembly inserted through the opening and axially movable within the chamber of the syringe barrel, with the plunger assembly further including a plunger rod having an elongated body extending between a proximal end and a distal end and a stopper attached to the distal end of plunger rod and positioned within the barrel chamber. The stopper is composed of a blended material including an elastomeric material and an intermixed material having a coefficient of thermal expansion lower than the elastomeric material.

Abstract: A medical device includes a container defined by walls and having a first end having an opening. The opening is sealed by a rubber component. The rubber component is formed from a self-lubricating rubber formed from a rubber composition including a halogenated isobutylene-isoprene co-polymer and at least one of (1) clay minerals or silica and (2) a liquid polyisoprene and butadiene homopolymer. A rubber component configured for use in a medical device and a rubber composition are also disclosed.
