    摘要: A method for the automated manufacture of defibrillation lead electrodes is disclosed. A metallic defibrillation electrode coil is first embedded in silicone rubber. The location of the coil is mapped using a machine vision system and then a CO.sub.2 laser is used to ablate the silicone overlying the coil to expose a controlled portion of the coil while leaving the remainder securely embedded in the silicone. The power density of the laser is below that which would affect the surface or bulk properties of the coil.

    摘要: Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. The band may be implanted via translumenal access or via thoracotomy.
