    摘要: Disclosed are devices and methods for delivering several sutures accurately and simultaneously around the perimeter of an annular prosthetic device (prosthetic heart valve, annuloplasty ring, etc.) to secure the prosthetic device within a native heart valve region. Devices can comprise a proximal handle portion including an actuator and a distal suturing portion including several curved and straight needles arrayed around the shaft axis. The straight needles and the curved needles are configured to simultaneously guide a plurality of sutures through the native tissue and through the annular prosthetic device. The actuator can cause the straight needles to move axially relative to the curved needles and can also cause the curved needles to rotate, such that the motions are coordinated to simultaneously place all the sutures.

    摘要: A suturing device includes a curved needle, a suture, an elongate body, an actuator and a curved needle holder. The suture connects with the curved needle. The actuator interacts with the elongate body and is operable between a first operating position and a second operating position. The curved needle holder extends away from a distal end portion or is provided as part of the distal end portion of the elongate body. The curved needle holder includes a distal end section having a distal-most tip. The curved needle holder includes an inner surface defining a needle passage for holding the needle and a distal opening. The curved needle has a curved needle radius and the curved needle passage has a curved needle passage radius that is different than the curved needle radius and the curved needle frictionally engages the inner surface when the needle is in a retracted position.

    摘要: A medical device includes a clevis, a first jaw, and a second jaw. The first jaw includes a first proximal gripping portion and a first distal gripping portion, and the first proximal gripping portion includes a first needle alignment portion. The second jaw is coupled to the clevis and includes a second proximal gripping portion and a second distal gripping portion, and the second proximal gripping portion includes a second needle alignment portion. The first and second needle alignment portions are located opposite each other when in the closed orientation. The first and second needle alignment portions define a clamp path when in the closed orientation within which the curved portion of the needle is received when the second jaw is in the open orientation. The first and second needle alignment portions are configured to rotate the needle when moving to the closed orientation.

    摘要: A tissue closure device includes a needle and a suture extending therefrom, a proximal head including a proximal slot and a proximal locking mechanism for releasably engaging a first end of the needle in the proximal slot in a first configuration, and a distal head movably coupled to the proximal head so that the proximal and distal heads are movable relative to one another between an open configuration, in which a target tissue is received therebetween, and a closed configuration, in which the target tissue gripped therebetween. The distal head includes a distal slot and a distal locking mechanism for releasably engaging a second end of the needle in the distal slot in a second configuration, the needle movable between the first and second configurations by rotating the needle, the needle alternatingly passed between the proximal and distal heads to thread the suture through the target tissue.

    摘要: A needle reload device includes a loading assembly including a needle holder pulley and a needle release arm. The needle holder pulley includes a base including first and second portions configured to receive a needle. The needle release arm is transitionable between an engaged state, in which the needle release arm engages the needle holder pulley to inhibit rotation of the needle holder pulley, and a disengaged state, in which the needle release arm is disengaged from the needle holder pulley such that the needle holder pulley is rotatable. When the needle release arm is in the engaged state, the first portion of the needle holder pulley is positioned between jaws of a stitching device, and when the needle release arm is in the disengage state, the second portion of the base of the needle holder pulley is positioned between the jaws.
