Arthroscopic devices adapted for minimally invasive procedures, such as bone augmentations and reconstructive surgery, are provided. The arthroscopic devices include a drill guide adapted for efficiently and accurately positioning pilot holes and surgical instrumentation relative to the bone; a surgical cable, such as an elastomeric surgical cable, adapted for applying a compressive force across the bone fragments after the surgical repair to promote healing; and a tensioner and crimping device for applying tension to the surgical cable and securing the surgical cable in place. A surgical procedure is also disclosed where a cerclage is applied arthroscopically by passing a member such as an elastomeric ribbon through the glenoid and a bone graft, where the member is tensioned and fixed into place to hold the bone graft in firm contact with the glenoid to facilitate healing.

A method cinches a suture. The method provides a cinch having a suture capturing portion configured to capture a suture, a cinch lock coupled with the suture capturing portion, and a cinch anchor having a lumen. The suture capturing portion is extended out of the lumen to capture the suture. The suture is captured by the suture capturing portion. The suture capturing portion is retracted into the lumen of the cinch anchor. The suture is cinched between the cinch lock and the cinch anchor.

Systems and methods for anchoring an implant

The invention relates in some aspects to a device for use in anchoring an implant, including anchors, sutures, implants, clips, tools, lassos, and methods of anchoring among other methods. Anchors as disclosed herein could be utilized to secure a coaptation assistance device, an annuloplasty ring, an artificial valve, cardiac patch, sensor, pacemaker, or other implants. The implant could be a mitral valve ring or artificial mitral valve in some embodiments.

Heart valve repair method

The present disclosure provides a heart valve repair method, comprising: advancing a distal end of a suture implanting apparatus from an outside of a body through a transapical approach into a left ventricle or a right ventricle of a heart; holding each leaflet of a heart valve with the distal end of the suture implanting apparatus; implanting at least one suture into the leaflet; withdrawing the suture implanting apparatus from the body; advancing a distal end of a suture locking apparatus from the outside of a body through a transapical approach into the corresponding left ventricle or the corresponding right ventricle; using the suture locking apparatus to lock the plurality of sutures; and withdrawing the suture locking apparatus from the body. The heart valve repair method has a simple surgical procedure, a low degree of patient trauma, and a high success rate of surgery.

A SUTURING DEVICE

A suturing device (1) for suturing parts (5,6) together of a lumen (8) with one or more sutures (3) comprises an actuator (34) having a handle (33) and first and second operating elements (60,68) slideable longitudinally on the handle (33). A tubular shield (35) extends from the handle (33), and a cannula (40) slideable in the tubular shield (35) is connected to the first operating element (60) for urging the cannula (40) between a withdrawn state within the tubular shield (35) to an extended state extending from the tubular shield (35). An elongated push rod (52) slideable in the cannula (40) terminating in a distal hook (55) is coupled to and operated by the second operating element (68). Anchor elements (22) of the suture (3) are located in the cannula (40), and are sequentially urged therefrom by the push rod (52), as the cannula (40) sequentially pierces through the parts (5,6). A loop (26) of the suture (3) is engaged by the hook (55), which is then withdrawn into the tubular shield (35) for engaging the adjustment element (25) of the suture (3) against an abutment face (38) of the tubular shield (35) for in turn drawing the anchor elements (22), and in turn the parts (5,6) of the colon (8) together. The adjustment element retains the parts (5,6) together.

TRACTION TOOL, TRACTION SYSTEM, AND TRACTION METHOD AND SUTURING METHOD FOR SUTURE THREAD

A traction tool for performing traction, of a suture thread under a flexible endoscope is provided. The traction toot includes a first holder configured to hold the suture thread or a suture needle attached to the suture thread; a second holder having an engaging surface configured to engage the suture, thread such that the suture thread is capable of advancing and retracting and configured to release an engagement with the suture thread; and a guide member holding the first holder and the second holder such that the first holder and the second holder are relatively movable.

TRACTION TOOL, AND TRACTION METHOD FOR SUTURE THREAD AND SUTURING METHOD
20230200804 · 2023-06-29 ·

A traction tool for performing traction of suture thread under a flexible endoscope is provided. The tool includes a shaft, a first holder which is provided at a distal end of the shaft and is configured to hold the suture thread or a suture needle attached to the suture thread, and second holder which is provided closer to a proximal end side of the shaft than the first holder and to which the suture thread is hooked. The second holder is expandable in a radial direction of the shaft.

Methods of anchoring cardiac implants using knotless suture fasteners

Devices and methods for securing prostheses such as heart valves or annuloplasty rings with sutures and without using knots are disclosed. The devices are particularly well suited for traditional surgery or minimally invasive surgery, and improve the ease of implantation by eliminating surgical knots a clinician would normally tie in the limited space in and around the implant site. The devices have opposed the clamp halves surrounded by a coil spring. Sutures pass between the clamp halves and the coil spring has an inner coil diameter sufficient to compress the sutures between the clamp. A retention member positioned between the clamp halves maintains a minimum space and therebetween to enable the locking device to be slid along the sutures into position, and to adjust the tension of the sutures therethrough. A delivery tool may be used to deliver and deploy the locking devices.

EDGE TO EDGE REPAIR OF THE MITRAL VALVE
20230200994 · 2023-06-29 · ·

The present invention describes systems and methods for treating mitral valve regurgitation. The treatment includes a systems and method of modifying the mitral valve by attaching a device to each leaflet and pulling them toward each other to stop mitral valve regurgitation.

Method and apparatus for transvascular implantation of neo chordae tendinae

Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium, through the mitral valve, and into the left ventricle. A ventricular anchor is deployed from the catheter and into a wall of the left ventricle, leaving a ventricular suture attached to the ventricular anchor and extending proximally through the catheter. A leaflet anchor is deployed to secure a mitral valve leaflet to a leaflet suture, with the leaflet suture extending proximally through the catheter. The leaflet suture is secured to the ventricular suture to limit a range of travel of the leaflet in the direction of the left atrium. Also disclosed is an assembled in situ mitral valve leaflet restraint, having a neo papillary muscle and a neo chordae tendinea.
