摘要： A medical electrical lead with a tip-ring assembly optimized to resist damage during extraction. The lead includes an elongated plastic tube and at least two elongated conductors mounted in the plastic tube. A tip-ring assembly is mounted to the distal end of the tube, the tip-ring assembly including a ring electrode coupled to one of the conductors, a tip electrode located distal to the ring electrode and coupled to another of the conductors and two molded plastic components separately fabricated of a plastic harder than the plastic tube, adhered to one another and together defining a circumferential groove in which the ring electrode is located and mechanically coupled to the tip electrode. The tip electrode may be provided with a proximally extending electrode shank covered by a tine sleeve which is fabricated of a plastic softer than the molded plastic components and is adhered to more distally located molded plastic component. The more distally located molded plastic component preferably overlaps the electrode shank to provide a stronger structure.

摘要： Coating an implantable device, such as micro electromechanical devices, is highly desirable to protect the implantable device from corrosion. A coating method includes depositing, preferably by plasma glow discharge, a reactant monomer on at least one surface of an implantable device, preferably at ambient temperature. The method will likely decrease the manufacturing time required for assembling such devices because completely assembled devices can be coated.

摘要： The present invention provides a method for modifying a pyrolytic carbon surface to improve adhesion between it and a subsequently added polymer and/or a bio-active compound. In particular, plasma depositing an oxygen-containing, silicon-containing film forming monomer on a pyrolytic carbon surface improves adhesion of a polymer thereto, wherein the modified pyrolytic carbon surface and silicone rubber has a wet adhesion peel force greater than the wet adhesion peel force between an unmodified pyrolytic carbon and silicone rubber as measured by ASTM D 903-49 after 28 days in an aqueous environment, typically, at least 10 times greater.

摘要： Antimicrobial compounds, such as silanol or alcohol, include a protecting or leaving group that can protect the compound from degradation during the process of preparing a medical device containing the compound or reduce the volatility of the compound relative to its counterpart without the leaving group. Nearly any hydrolysable leaving group may be employed. The leaving group may be an agent that may serve a therapeutic function in addition to protecting or retaining the antimicrobial agents.
