  • Publication number: 20030181928
    Abstract: A method for placing a splint assembly transverse a heart chamber includes providing an elongate member having a first end and a second end and a deployable heart-engaging assembly connected to at least the first end. The method includes advancing the elongate member through vasculature structure and into the heart chamber such that the first end of the elongate member extends through a first location of a wall surrounding the heart chamber and the second end extends through a second location of the heart chamber wall substantially opposite the first location. A deployable heart-engaging assembly is deployed such that it engages with a first exterior surface portion of the heart chamber wall adjacent the first location. The elongate member is secured with respect to the heart with a second heart-engaging assembly connected to the second end. The second heart-engaging assembly engages with a second exterior surface portion of the heart chamber wall adjacent the second location.

  • Patent number: 6537198
    Abstract: A splint assembly for placement transverse a heart chamber to reduce the heart chamber radius and improve cardiac function has a tension member formed of a braided cable with a covering. A fixed anchor assembly is attached to one end of the tension member and a leader for penetrating a heart wall and guiding the tension member through the heart is attached to the other end. An adjustable anchor assembly can be secured onto the tension member opposite to the side on which the fixed pad assembly is attached. The adjustable anchor assembly can be positioned along the tension member so as to adjust the length of the tension member extending between the fixed and adjustable anchor assemblies. The pad assemblies engage with the outside of the heart wall to hold the tension member in place transverse the heart chamber. A probe and marker delivery device is used to identify locations on the heart wall to place the splint assembly such that it will not interfere with internal heart structures.

  • Patent number: 6267782
    Abstract: A variety of new ways can be used for associating antimicrobial elemental metal with a medical article. The associated antimicrobial metal reduces the risk of infection associated with the medical use of the medical article. New medical articles are produced by some of these new approaches. Some of the methods involve ways of adjusting the dissociation rate of associated elemental metal such that desired degrees of antimicrobial activity can be achieved over selected periods of time.

  • Patent number: 6254635
    Abstract: Medical articles can include biocompatible material with a deposit of anticalcific elemental metal. The biocompatible material can be tissue, fabric or the like. The biocompatible material can be configured on the medical article such that when the medical article is positioned for its intended use, the biocompatible material is substantially removed from blood flow or is in a low blood flow area effectively removed from vascular blood flow. Gas phase or solution phase methods can be used to deposit the anticalcific elemental metal.

  • Patent number: 5958669
    Abstract: Crosslinking to prepare fixed tissue or to crosslink modification molecules to tissue is carried out with an apparatus and method wherein diffusion through a semipermeable is used to provide a selected molecular weight distribution of oligomers of a crosslinking compound that polymerizes spontaneously in solution to produce oligomers such as glutaraldehyde. The membrane has a molecular weight exclusion limit that prevents oligomers above a certain molecular weight from passing. Tissues treated with the size selected oligomers have improved properties. In the apparatus, the membrane separates a solution containing the crosslinking compound and oligomers from a solution in which crosslinking is carried out. The selected molecular weight distribution of oligomers diffuses through the membrane into the solution where tissue is crosslinked or a beneficial molecule is crosslinked to tissue.
