Abstract
A device for positioning suture through tissue, the device including a proximal elongate member having a longitudinal axis, the proximal elongate member being configured to receive a needle, and a tissue locator disposed distal the proximal elongate member, the tissue locator being coupled to an elongate member extending through the proximal elongate member and including a leg with a needle receiving opening configured to accommodate the needle. Proximal movement of the elongate member compresses the tissue locator and folds the leg of the tissue locator, the leg transitioning from extending longitudinally to extending outwardly in relation to a position of the leg in a pre-compressed state.
Claims17
A device for positioning suture through tissue, the device comprising:
- a proximal elongate member having a longitudinal axis, the proximal elongate member being configured to receive a needle, the needle being inclined in relation to a longitudinal axis;
- and
- a tissue locator disposed distal the proximal elongate member, the tissue locator being coupled to an elongate member extending through the proximal elongate member and comprising a leg with a needle receiving opening configured to accommodate the needle, wherein proximal movement of the elongate member compresses the tissue locator and folds the leg of the tissue locator, the leg transitioning from extending longitudinally to extending outwardly in relation to a position of the leg in a pre-compressed state.
A device for positioning suture through tissue, the device comprising:
- a proximal elongate member having a longitudinal axis;
- and
- a tissue locator coupled to an elongate member extending through the proximal elongate member, the tissue locator comprising a tubular portion having slits with two through holes disposed between circumferentially adjacent slits,
- wherein proximal movement of the elongate member transitions a leg portion of the tubular portion disposed between the adjacent slits from extending longitudinally to a deployed state with the leg portion extending outwardly from the longitudinal axis, and
- wherein the tissue locator is configured to return to a predefined shape following removal of a force applied by the elongate member through the proximal movement.
A device for positioning suture through tissue, the device comprising:
- a proximal elongate member having a longitudinal axis, the proximal elongate member being configured to receive a needle;
- and
- a tissue locator disposed distal the proximal elongate member, the tissue locator being coupled to an elongate member extending through the proximal elongate member, the tissue locator comprising a tubular portion having slits and a through hole and a needle receiving opening disposed between circumferentially adjacent slits,
- wherein proximal movement of the elongate member compresses the tissue locator to a compressed state and folds four leg portions of the tubular portion disposed between the adjacent slits, the leg portions transitioning from extending longitudinally to extending outwardly in relation to a position of the leg portions in a pre-compressed state.
