Abstract: A modular driveline includes a modular portion including a cable and a connector, the cable having terminations, and a percutaneous portion including a cable and a connector, the cable having terminations. The percutaneous portion connector couples to the modular portion connector, and cable terminations at the connectors are captured in the connectors by potting. The cable can include an inner member, conductors disposed about the inner member, a covering about the conductors, a layer extruded onto the covering, an armor braid over the extruded layer, and an outer jacket extruded over the armor braid.

Abstract: A vascular graft, such as an AAA stent graft, includes a core zone of PET fabric with a non-porous coating comprising a polyurethane, such as Thoralon®, disposed on at least one surface. The coating provides a barrier to prevent short and long term leakage of fluids through the pores of the PET fabric core zone. A method for sealing the pores of a porous PET graft includes the step of coating at least one surface of said graft with at least one polyurethane, or mixtures and combinations thereof. Preferably, the coating is Thoralon®. A method for making a vascular prosthesis includes the steps of providing a core zone of PET fabric, and coating at least one surface of the core zone with at least one polyurethane, or mixtures and combinations thereof, such as Thoralon®. Finally, a method of repairing or treating a defective vessel includes the step of reinforcing or replacing the defective vessel with a graft according to the invention.

Abstract: A method for forming a kink resistant, blood impermeable graft comprises the steps of: providing a crimped substrate of polymer fabric; coating the outer surface of the substrate with a first solution comprising a first polymer and a particulate in a first solvent; allowing the first solution to dry, thereby forming a first coat on the substrate; coating the first coat with a second solution comprising a second polymer in a second solvent; and immersing the coated substrate in a third solvent to precipitate the second polymer from solution, thereby forming a porous second coat. The third solvent also dissolves the salt in the first coat to form pores in the first coat. The first and second polymer solutions do not penetrate to the interior surface of the substrate of the graft. Vascular prostheses made by this method are blood impermeable and kink resistant and are particularly useful as outflow cannulas for ventricular assist devices.

Abstract: The invention relates to epoxy-terminated polymers and copolymers derived from hydrosilyl-terminated hydrogenated polydienes and polyvinyl aromatics, and a process for preparing these polymers and copolymers. The epoxy-terminated polymers and copolymers are reactive with a variety of polymer functionalities such as carboxyl, hydroxyl, and amino groups to produce copolymers useful as molded articles and as compatibilizers for compositions containing polyesters and polyolefins.
