  • Publication number: 20180125470
    Abstract: The present invention relates to devices 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 introducing a mechanical closure device into an atrium of the heart and transeptally deploying the closure device across the interatrial septum to provide proximation of the septum secundum and septum primum.

  • 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.

  • Patent number: 8047982
    Abstract: A urethra support having an elongated mesh tape portion and a mesh extension affixed to the tape portion transverse thereto. In accordance with a method of the invention, the urethra support is inserted into the lower pelvic cavity of a patient with the tape portion forming a sling extending beneath and supporting the urethra of the patient. In this position, the tape portion is generally perpendicular to the urethra. The extension is inserted into the peri-urethral fascia along at least a portion of the length of the urethra. This induces the formation of scar tissue proximate the extension, with the scar tissue eventually contracting thereby compressing the urethra.

  • Patent number: 7967841
    Abstract: A method for repairing friable tissue having a defect therein includes providing a looped barbed suture having a plurality of barbs extending outwardly therefrom along at least a portion of a length thereof, and having first and second ends, first and second end portions and a middle portion therebetween. The first and second ends are fixedly coupled to a single needle, and the plurality of barbs extends outwardly away from the needle. The steps further include placing the looped barbed suture around an outer surface of the friable tissue in a spaced apart configuration and so as to extend across the defect, passing the needle through the friable tissue and around the middle portion of the looped barbed suture one or more times at the middle portion, and removing the needle from the looped barbed suture.

  • Publication number: 20080281357
    Abstract: A looped tissue-grasping device includes a looped suture having two ends swaged to a needle and a plurality of tissue-grasping elements provided on the looped suture. The device is used for joining bodily tissue in surgical applications and wound repair. The configuration of the tissue-grasping elements permit movement of the suture through the tissue in the direction the needle is pulled and, prevent slippage or movement of the suture in a direction opposite to the direction of movement of the needle.
