Abstract
A vessel closure device comprising a proximal end includes a first actuator, a distal end including a suturing mechanism, and first and second needles associated with the suturing mechanism. At least one of the first and second needles is coupled to the first actuator. The suturing mechanism is activated within the vessel through an opening in the wall of the vessel. The first and second needles are directed through the vessel wall adjacent to the opening to direct a tensile member adjacent to the opening for closing and sealing the opening.
Claims5
A method of closing an opening in a vessel, the method comprising:
- directing a suturing mechanism, the suturing mechanism including a pivotal element and being coupled to a distal end of an elongate shaft, through the opening and into the vessel;
- activating the pivotal element into a deployed orientation after the suturing mechanism is positioned within an interior of the vessel;
- directing a first needle through a vessel wall adjacent to the opening and coupling the first needle to a first end of a coupling member;
- directing a tensile member coupled to the first needle through the vessel wall adjacent to the opening using the first needle;
- directing a second needle through the vessel wall adjacent to the opening and coupling the second needle to a second end of the coupling member;
- retracting the first needle from the vessel wall;
- retracting the second needle from the vessel wall;
- pulling the tensile member through the vessel wall adjacent to the opening using the coupling member;
- deactivating the pivotal element;
- withdrawing the suturing mechanism from the vessel;
- and
- tightening the tensile member to close and seal the opening.
