  • Patent number: 8945179
    Abstract: Described are method and device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart, and related methods of using such closure devices for closing the passageway. The method includes locating a distal end of a closure device adjacent to the passageway. The closure device may include a closure line with proximal and distal ends, an expandable tissue anchor located along the distal end of the closure line, and an expandable occluder member located along the proximal end of the closure line. The expandable tissue anchor is deployed into tissue adjacent to the passageway. The expandable occluder member is deployed adjacent to the passageway such that the expandable occluder member substantially covers the second opening to the passageway.

  • Patent number: 8876860
    Abstract: The present invention provides a porous structure that works very effectively to seal a puncture site with optimum porosity, absorbent capacity and perfect anatomical fit. The plug density and other fiber properties/geometry (total denier; number of filaments; etc) have provided an efficient structure that allows instantaneous absorption of blood during deployment. The final size of the plug with absorbed fluids provides an anatomical fit and seals the puncture site within few minutes after deployment.

  • Patent number: 8834562
    Abstract: The present invention relates to a delivery system for delivering a device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart. The delivery system has an elongate member having a proximal and distal end. A deflectable needle assembly having luminal and abluminal surfaces is slideably engaged within the elongate member. An actuator is slideabley engaged within the elongate member and attached to the needle tip assembly such that translational movement of the actuator causes deflection of the deflectable needle assembly.

  • Patent number: 8777984
    Abstract: A device and method for deploying a mechanical closure device for closing a passageway in a body, for example a patent foramen ovale (PFO) in a heart. The deployment device has a first tubular structure having proximal and distal ends. A second tubular structure is substantially coaxial to and slideably engaged within the first tubular structure. The second tubular structure has a first substantially linear shape when constrained within the first tubular structure, and a second curvilinear shape when telescopically extended from the distal end of the first tubular structure. A third tubular structure is substantially coaxial to and slideably engaged within the second tubular structure. The third tubular structure is configured to provide sufficient rigidity to push the mechanical closure device from the distal end of the second tubular structure, and provide sufficient flexibility to assume a curvilinear shape when deflected by the second tubular structure.
