  • Patent number: 7963973
    Abstract: A tissue connector assembly comprising a multiple loop fastener movable between an open configuration and a closed configuration and a restraining device attached to the fastener for restraining the fastener in its open configuration provides for a self-closing, multiple suture fastener. A needle may be releasably attached to the fastener. A method for connecting tissues is also disclosed. The method includes inserting a fastener through tissue with the fastener being biased in an open position by a restraining device secured to the fastener, threading the fastener through more than one stitch, and removing the restraining device from the fastener.

  • Publication number: 20030014073
    Abstract: This is an implant for placement in the human body and an assembly for so placing that implant. Most desirably, it is an implant for use in the vasculature of the human body and is used to occlude some space in that vasculature as a portion of a treatment regimen. The implant itself is preferably a component of a deployment device using an electrolytically severable joint. The implant is electrically isolated from the electrolytically severable joint by a highly resistive or insulative layer. Such isolation and minimization of the conductive pathway from the placement apparatus to the body's fluids appears to enhance the susceptibility of the electrolytic joint to quick erosion and detachment of the implant from the deployment media. Although the implant itself is preferably a vaso-occlusive device, it may instead be a stent, a vena cava filter, or other implant which may be installed in this manner.

  • Patent number: 5669931
    Abstract: An occlusive implant includes an elongated member having an end, a portion proximal to that end, and a portion distal to that end. The proximal portion is sufficiently flexible so that it can be folded upon itself and maintain that configuration without further restraint. At least a portion of the distal portion is preformed to have a first configuration when in a first state and a second configuration when in a second state. The distal portion second configuration has a flow resistance substantially greater than that of the proximal portion. When discharged in the region to be occluded, the proximal portion is forced into a mass around at least a portion of the distal portion secondary structure. As the mass builds in size, it is believed to frictionally engage the surrounding vasculature wall and anchor the implant thereto. The occlusive implant preferably is provided in an introducer cartridge for delivery in vivo.
