Abstract
A tissue anchor applicator includes an end effector assembly having first and second jaw members. The first jaw member includes a pair of spaced-apart arms configured to releasably retain a fastening member thereon. The second jaw member is configured for releasably retaining an anchor member thereon. One (or both) of the first and second jaw members is moveable with respect to the other from a spaced-apart position to an approximated position for securing tissue between the fastening member and the anchor member.
Claims21
A tissue anchor applicator, comprising:
- an end effector assembly, the end effector assembly including:
- a first jaw member including a pair of spaced-apart arms, the first jaw member configured for releasably retaining a fastening member thereon;
- and
- a second jaw member configured for releasably retaining an anchor member thereon, wherein at least one of the first and second jaw members is moveable with respect to the other from a spaced-apart position to an approximated position for securing tissue between the fastening member and the anchor member.
A tissue anchor assembly, comprising:
- an anchor member, the anchor member including a ball portion, a base, and a shaft interconnecting the ball portion and the base, the anchor member positionable adjacent a face of tissue;
- and
- a fastening member positionable adjacent an opposite face of tissue, the fastening member having a pair of spaced-apart arcuate arms connected to each other at first ends thereof and having free second ends, at least one of the arms being moveable with respect to the other between an at-rest position defining a first gap distance therebetween and an expanded position defining a second gap distance therebetween, the second gap distance being greater than a diameter of the shaft for positioning the fastening member about the shaft, the first gap distance being smaller than the diameter of the shaft for fixedly securing tissue between the anchor member and the fastening member when the fastening member is disposed about the shaft.
A tissue anchor assembly, comprising:
- an anchor member, the anchor member including a ball portion, a base, and a shaft interconnecting the ball portion and the base, the anchor member positionable adjacent a face of tissue;
- and
- a fastening member defining an opening extending therethrough, the fastening member positionable about an opposite face of tissue, the fastening member being transitionable from an at-rest position to an expanded position for passing the ball portion through the opening, the fastening member being transitionable back to the at-rest position once the ball portion has passed therethrough for retaining the fastening member about the shaft between the ball portion and the base to fixedly secure tissue between the anchor member and the fastening member.
A tissue anchor assembly, comprising:
- an anchor member, the anchor member including a ball portion, a base, and a shaft interconnecting the ball portion and the base, the anchor member positionable adjacent a face of tissue;
- and
- a fastening member, the fastening member positionable adjacent an opposite face of tissue, the fastening member including:
- a ring structure defining an opening extending therethrough;
- a suture coupled to the ring structure, the suture being moveable between a first position for passing the ball portion through the opening of the ring structure and a second position for retaining the fastening member about the shaft between the ball portion and the base to fixedly secure tissue between the anchor member and the fastening member.
