发明名称 Method of molding silicone elastomer drug carrier in an endocardial lead
摘要 A drug-eluting endocardial lead and method of manufacture. The silicone elastomer of the present invention is ideally suited to a manufacturing environment due to its extended pot life and decreased curing time. A preferred silicone elastomer is comprised of a multi-part mixture having at least a base portion and a curing portion. Additionally, since curing does not begin until the base and curing portions are combined, the mixing can be physically undertaken closer to the location of the endocardial lead and the curing "clock" does not start until the mixing occurs and external heat is applied. Since the silicone elastomer formed by base and curing components have improved the pot life and curing characteristics, the mixture is suitable for mixing with a steroid and then dispensing into an endocardial lead tip thus eliminating current design limitations imposed by current art while concomitantly minimizing manufacturing costs.
