  • Patent number: 10772623
    Abstract: A coupling system includes an applicator tool and an attachment ring mounted on the applicator tool. Clips are contained within the applicator tool and are deployed through the attachment ring in order to anchor the attachment ring to biological tissue. When deployed, tips of the clips follow a curved trajectory through an annular cuff of the attachment ring and through the underlying tissue. The tips loop back out of the tissue and to a location where they are later trapped or clamped by the attachment ring. While the tips are trapped or clamped, the applicator tool cinches the clips by pulling rear segments of the clips. Thereafter, the applicator tool disconnects from the attachment ring which remains anchored to the tissue and serves as a coupling for a cannula. The cannula can have movable lock members that secure it to the attachment ring.

  • Publication number: 20130012969
    Abstract: Disclosed herein is a stent for connecting adjacent tissues of the organs of a patient. The stent includes a hollow cylindrical body which is formed by weaving a superelastic shape-memory alloy wire in an overlapping manner such that rhombic openings are formed, and wing parts which are provided by expanding respective opposite ends of the hollow cylindrical body outwards and turning the opposite ends inside out on bent portions. The wing parts face each other so that the wing parts are tensed in a longitudinal direction of the cylindrical body. Thereby, the wing parts can elastically move inwards or outwards with respect to the longitudinal direction to automatically adjust a distance between the wing parts in response to the distance between the adjacent tissues of the organs or thicknesses of walls of the organs, so that the wing parts are put into close contact with the adjacent tissues.

  • Patent number: 8187299
    Abstract: The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools which are introduced to a heart chamber. Preferably, the tissue structures will be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment.

  • Patent number: 8012164
    Abstract: An auger is axially fixed to and positioned within a cutter. The auger and cutter advance at the same time relative to a contact structure placed against a vessel, penetrating the wall of the vessel and cutting a tissue plug. When the auger and the cutter are retracted from the vessel wall, the tissue plug is retained by the auger and cutter and removed from the vessel wall. The auger and the cutter thus create an opening in the vessel wall, without the need for a prior incision in that wall.

  • Patent number: 7931662
    Abstract: A surgical marker/connector in the form of a ring made of a shape memory alloy such as NITINOL is suitable for laparoscopic installation in a patient's body. The ring preferably includes a plurality of small suture attachments in the form of loops that are disposed on the periphery of the ring and which lie in a plane that includes the ring itself. The loops are large enough to receive sutures which, in turn, can be used to connect the ring to a portion of a patient's body, or to connect separate portions of a patient's body to each other using the marker/connector as an intermediate connector. Prior to installation, the ring can be wrapped tightly about an elongate member such as a mandrel, which than can be inserted into the patient's body through a trochar or cannula. After insertion, the ring will change temperature and resume its original configuration where it can be sutured in place as desired.
