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: A syringe that includes an adapter section and a barrel having a chamber that holds a fluid. The adapter section includes outer and inner walls that form a first groove. The inner wall includes barrel threads and the outer wall includes a first projection. A cap having cap threads engages the barrel threads to removably attach the cap to the adapter section. A locking element having a sidewall that includes a second projection is received in the first groove and removably attached to the cap by an interference fit. Rotation of the cap causes upward movement of the cap that overcomes the interference fit thereby removing the cap. The locking element is prevented from being removed from the first groove due to contact between the first and second projections. Presence of the locking element in the first groove after the cap is removed provides evidence of tampering.

Abstract: Medical devices incorporate four-lead thread, male or female Luer connectors, also referred to as four-start thread, Luer connectors. The Luer connector comprises a monolithic, molded-polymer, tubular body having inner and outer wall circumferential surfaces and four-lead helical threads formed on one of the wall circumferential surfaces. The helical threads circumscribe a nested, concentrically aligned, frusto-conical, Luer-tapered, mating surface. The four-lead thread configuration reduces axial, cross-sectional area of each thread, which facilitates more uniform mold filling and cooling while injection molding the medical device, more uniform finished product and material savings, compared with traditional two-lead thread Luer connectors.

The closed cell foam structure may have a polygonal or star shape, wherein fluid can flow through a gap formed between the closed cell foam structure and the inner surface of the cavity. The open cell foam structure may be impregnated with disinfectant, whereby compression of the open cell foam structure causes excretion of the disinfectant upon insertion of a luer connector.

Abstract: A medication injection pen comprises a dose set knob rotatable with respect to a housing to set a desired injection dose. The dose set knob comprises at least one internal thread. A leadscrew includes a thread element for advancing in a first direction via a corresponding thread engagement. A driver is rotationally fixed to the leadscrew and is rotatable in a first direction to rotate and advance the leadscrew in the first direction. The setback member is rotationally fixed to the driver. The dose stop member is rotationally coupled to the setback member and is axially movable relative to the dose set knob when the dose set knob is rotated relative to the setback member. Axial movement of the dose stop member limits the user from setting a dose that is greater than an injectable volume of medication remaining in a cartridge.
