  • 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: 20150289877
    Abstract: A coupling system includes an applicator tool, an anastomotic prosthesis mounted on the applicator tool, and an engagement device. The applicator tool deploys a securement through the prosthesis and tissue which leaves the prosthesis attached to the tissue. The engagement device selectively engages the applicator tool onto the tissue, with the use of suction, in order to facilitate accurate placement of the prosthesis on the tissue and facilitate deployment of the securement into the tissue. The applicator tool and the tissue are able to move together while the engagement device prevents or inhibits relative movement between the applicator tool and the tissue. A method for securing an anastomotic prosthesis to tissue includes applying of suction to engage an applicator tool to the tissue while a securement is deployed out of the applicator tool and into the prosthesis and the tissue.
