SUTURE PASSER DEVICES AND METHODS

Devices, systems and methods for passing a suture. In general, described herein are suturing devices, such as suture passers, as well as methods of suturing tissue. These suture passing devices may include dual deployment suture passers in which a first distal jaw member is moveable at an angle with respect to the longitudinal axis of the elongate body of the device and the second distal jaw member is retractable proximally to the distal end region of the elongate body and/or the first jaw member.

VALVE LEAFLET TREATMENT SYSTEMS AND METHODS

An implant comprises a leaflet-augmentation patch, a patch anchor, and a cord. The patch comprises a flexible sheet, and a frame that supports the flexible sheet. The frame defines a spring configured to tension the cord. The cord couples the patch anchor to the patch in a manner in which anchoring the patch anchor to a first leaflet of a heart valve of a subject positions the patch to coapt with a second leaflet of the valve during ventricular systole. Other embodiments are also described.

Apparatus and methods for Achilles tendon repair

Apparatus and methods for Achilles tendon repair are described where an elongate tendon repair assembly may be introduced into a single incision to access the damaged tissue. The assembly may define a channel for receiving a portion of the tendon and which may provide support to the tissue during repair. One or more retractable needles each carrying a length of suture may be deployed within the channel for piercing through the tendon and a cinching member may secure each of the suture lengths for tensioning the suture against the damaged tendon. Once the suture lengths have been deployed, the needles may be retracted and the device removed from the incision.

SURGICAL TOOLS WITH OCCLUDED BLADE

Surgical tools that are capable of both manipulating a needle and cutting surgical thread during a suturing operation can sometimes be problematic due to inadvertent severing of the surgical thread. Surgical tools capable of exposing a bladed cutting surface only when severing of surgical thread is desired can substantially alleviate this issue. Such surgical tools may comprise an end effector comprising an end effector axle, a first jaw and a second jaw rotatably mounted to the end effector axle, and a first cutting body having a first blade and second cutting body having a second blade. The first cutting body is configured to move in tandem with the first jaw and the second cutting body is configured to move in tandem with the second jaw, such that the first and second blades are occluded when the first and second jaws are closed or partially opened.

Devices are provided for a suturing device used during laparoscopic surgical procedures. A suturing needle includes a shaft forming a rod axis; a curved body having a piercing tip at a first end and a base at a second end; and an arm extending radially from the shaft to the base of the curved body such that the curved body is positioned in a plane orthogonal to the rod axis of the shaft and rotatable about the shaft in the plane orthogonal to the rod axis. The suturing device includes a housing, a suturing needle, one or more sutures, a suture magazine configured to hold the one or more sutures, and a drive system, whereby the drive system may actuate the suturing needle to rotate in the plane orthogonal to the drive system, allowing the suturing needle to drive in to and out of tissue to apply a suture.

PURSESTRING SUTURE RETRACTOR AND METHOD OF USE
20210085310 · 2021-03-25 ·

Systems, devices, and methods for endoscopically retracting a target tissue. The device includes a first shaft and a second shaft slidably coupled thereto. An internal member extends in a transverse direction from the first shaft and is configured for advancement through a penetration in the target tissue to atraumatically engage a distal surface of the target tissue after being advanced therethrough. A pair of external members extend from the second shaft generally parallel to the transverse direction. The external members are spaced apart and are configured to atraumatically engage a proximal surface of the target tissue when the internal member is moved longitudinally relative to the external members. The internal member applies traction to the target tissue when retracted past the pair of external members, which apply counter-traction to the target tissue on opposing lateral sides of the internal member, to re-shape the target tissue and enable subsequent suture placement.

FIXATION DEVICES, SYSTEMS AND METHODS FOR ENGAGING TISSUE

System for fixation of leaflets of a heart valve including a delivery catheter having an elongated shaft, a proximal end portion and a distal end portion configured to be positioned proximate native leaflets of a heart valve from a remote vascular access point, the delivery catheter further includes a rotatable actuator rod having a threaded fastener at a distal end thereof, and a fixation device releasably coupled by a threaded connection to the threaded fastener of the actuator rod. The fixation device includes a first arm moveable between a closed position and an open position, a second arm moveable between a closed position and an open position. The fixation device further includes a first gripping element movable relative to the first arm in the open position, the first gripping element biased toward the first arm to capture a first leaflet of the heart valve therebetween, and a second gripping element movable relative to the second arm in the open position, the second gripping element biased toward the second arm to capture a second leaflet of the heart valve therebetween. The first gripping element and the second gripping element each includes a plurality of barbs extending therefrom, the plurality of barbs of each of the first gripping element and the second gripping element being aligned transversely in at least one row. The fixation device further includes a covering disposed on each of the first gripping element and the second gripping element, wherein the plurality of barbs of the first gripping element and the second gripping element, respectively, protrude through the covering.
