Suture passer devices and methods

Suture passer devices and methods of using the devices having one or more protective interlocks preventing or limiting operation of the suture passer when deployment of the needle may damage the apparatus or harm the patient. For example, described herein are suture passer devices that include an interlock preventing deployment of the tissue penetrator (needle) when the jaws are not clamped onto a tissue. Also described herein are interlocks preventing retraction of a jaw axially until the needle is retracted.

Apparatus and Method for Passing Suture Through Soft Tissue
20220387018 · 2022-12-08 ·

A system for passing suture through biological tissue using a cannula, introducer or other minimally invasive means, to approximate, ligate, fixate, and/or close biological tissue. The system includes a hand actuator mechanism, an elongated tubular member housing a deformable tubular needle therein in operative communication with the hand actuator mechanism, and a jaw mechanism disposed on the tubular member distal end. The jaw mechanism having top and bottom members and a floating pivot mechanism, the top and bottom members in operative communication with the floating pivot mechanism. The floating pivot mechanism providing pivotal and axial articulation of the top member with respect to the bottom member.

Surgical tool and method of use
11517301 · 2022-12-06 · ·

A surgical tool incorporates a suture guide with and ananchor driver supporting an anchor where the anchor is maintained at a distance from the suture guide until release of a detent mechanism. Thereafter, the anchor is allowed to move into proximity to the suture guide, fixing a suture supported by the suture guide to a substrate, the entire procedure being achievable with a single hand.

SELF KNOTTING SUTURING INSTRUMENT
20220378413 · 2022-12-01 ·

An aspect of the present disclosure provides a suturing instrument comprising: a plurality of hollow tubes; at least two stitching arms coupled to first end of the plurality of hollow tubes, the at least two stitching arms capable of moving between an open position and a closed position, wherein in the open position the at least two stitching arms are away from each other, and in the closed position the at least two arms are closer to each other; a needle coupled to at least one of the at least two stitching arms, wherein a suture is looped through the needle to enable suturing when the both arms are moved to the closed position; and a handle comprising at least two members coupled to a second end of the plurality of hollow tubes such that first member of the at least two members is fixed and a second member is movably coupled to the first member, wherein when the at least two members are closer the at least two stitching arms are in closed position, and when the at least two handles are moved away the at least two arms move from the closed position to the open position.

Method and apparatus for treating a hip joint, including the provision and use of a novel suture passer

A suture passer comprising: a shaft having an axis; a first jaw mounted to the shaft in alignment with the axis, the first jaw being configured to releasably support a length of suture thereon; a second jaw movably mounted to the shaft; and a needle movably mounted to the shaft, the needle having a hook and being configured to reciprocate in alignment with the axis so that the hook can selectively pass by the second jaw and engage suture releasably supported on the first jaw; wherein the first jaw comprises a spring for selectively binding the suture to the first jaw, and further wherein the spring comprises a recess for receiving the suture therein.

Surgical end effector assembly including a connector strip interconnecting a plurality of staples

A surgical staple cartridge is disclosed comprising a plurality of staples removably stored within the surgical staple cartridge. The staples comprise staple legs which extend from a staple base portion. The staple legs comprise staple tips configured to pierce tissue and contact a corresponding forming pocket of an anvil of surgical stapling instrument. The staples further comprise zones having different hardnesses.

Methods and devices for papillary suturing
11591554 · 2023-02-28 · ·

A minimally invasive device and method for suturing papillary muscles includes drawing a suture through a first papillary muscle using a needle, drawing the suture through a second papillary muscle, and tightening the suture to move at least one of the first papillary muscle and the second papillary muscle towards the other of the first papillary muscle and the second papillary muscle.

Implant placement systems and one-handed methods for tissue fixation using same

Described herein is a simplified placement system and method for a tissue graft anchor by which a surgeon may introduce one or more sutures into a hole in a boney tissue, apply a precise amount of tension to the sutures to advance a soft tissue graft to a desired location, and then advance the anchor into the bone, preferably while maintaining the requisite pre-determined suture tension and without introducing spin to the suture. Particularly preferred embodiments allow for the one-handed operation. To that end, embodiments in which relative axial movement between the inner tensioning device and outer driver device is optionally physically constrained, for example by means of cooperating and/or compressive elements disposed in the respective hub and handle portions, are described herein.

MEDICAL SYSTEMS, DEVICES AND METHODS ADAPTED FOR TISSUE FIXATION AND APPROXIMATING TISSUE DEFECTS

A medical device for approximating and securing tissue without requiring knots includes a lock-head, a strap section, distal protuberance, and a leader section. The device also includes a transition section between the leader and the strap section and a stiffening section proximal to the protuberance. The leader section is used to draw the strap section into the body through small apertures in tissue and the transition section provides a gradual transition in stiffness and size between the leader and the strap section. Tensioner and cutter and a threading tool configured to be slidably removed from a lumen of the tensioner and cutter is provided. A blade within the lumen of the tensioner and cutter is provided to cut excess leader and/or strap when the procedure is completed.

Suture passing device
11583269 · 2023-02-21 · ·

A suture passing device includes a jaw assembly that is moved to an open configuration after exiting a hollow needle distal tip and moved to a closed configuration when retracted into the needle tip. The jaw assembly may include a pair of jaw members biased to a default diverging configuration. A suture capturing mechanism formed on the jaw members securely captures suture to both push and pull the captured when the jaw assembly is retracted into the hollow distal tip. The jaw members have configurations of teeth that may be staggered axially and vertically.
