EDGE TO EDGE REPAIR OF THE MITRAL VALVE
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 mitral valve chord repair
Methods and devices for transvascular prosthetic chordae tendinae implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, the catheter can be anchored to a superior surface of a mitral valve leaflet and a leaflet anchor can be advanced into the mitral valve leaflet to secure the mitral valve leaflet to a leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.
Suture cinching device with cutter
Medical devices for cinch and cutting one or more suture, and methods for making and using such devices are disclosed. An example medical device may include a coupler, a sleeve releasably coupled to the coupler, a cutter slidably disposed within the sleeve, and a suture cinching member movable into and out of the sleeve. A wire may extend through and be longitudinally movable within the coupler to move the suture cinching member and cutter.
DISPOSABLE ARTHROSCOPIC SUTURE CUTTING DEVICE
A suture cutter that can easily load and retain a tensioned or un-tensioned in place for cutting. The cutter has a handle with a an integral lever and a shaft is coupled to and extending from the handle. A tip has a cutting channel with a cradle for entrapping a suture prior to cutting. A piston in the handle drives a blade pusher to cut the suture in response to movement of the lever. A guide assembly in the body is formed from a pair of members folded together via a living hinge to provide a slot for the head of the piston. The pusher is planar and oriented horizontally within the shaft, while the blade is planar and is oriented vertically at right angles to the pusher. The blade has a tab that is captured by a notch in the pusher to interlock the blade and the pusher.
JOINTED DEVICE FOR AUTOMATIC SUTURE AND METHOD FOR SAME
A device for automatic suturing includes a shaft having a longitudinal axis. The shaft has a joint rotatable about a joint axis which is at an angle>0° to the longitudinal axis. The device includes a clamp at a distal end of the shaft. The clamp is configured to be positioned over a length of tissue to be sutured. A driver is configured to engage with a screw of the shaft so that the driver translates along a length of the shaft when the driver is rotated. A helical needle is connected to the driver such that rotation of the driver causes rotation of the helical needle. In this way, the needle is advanced or retracted over a length of the clamp and over the joint of the shaft.
Patellar tendon graft and anterior cruciate ligament (ACL) reconstruction method using suture tape augmentation
The present disclosure generally pertains to methods and kits for preparing an ACL repair surgical implant, the method including drilling femoral and tibial bone plugs of a tendon graft to create medial to lateral holes, and passing a braided suture around the tendinous portion of the tibial end, through soft tissue, and out the tibial end. Next, an anterior to posterior femoral hole is drilled, and a flat-braided suture is passed through the femoral medial to lateral hole and, using a bent needle, passed through junctions of the femoral bone plug and the tendinous portion and out through junctions of the tibial bone plug and the tendinous portion on both sides of the graft. Ends of the flat-braided suture are crisscrossed through the medial to lateral tibial hole. A bone-to-bone fixation suture assembly is passed through the anterior to posterior femoral hole.
Suture clip deployment device
Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can then move distally to prepare to deploy the next suture clip.
Leaflet capture and anchor deployment system
Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, a leaflet connector carried by a distal end of the catheter can be anchored to a superior surface of a mitral valve leaflet. A needle is axially advanceable through the leaflet connector and through the leaflet. A leaflet anchor having a leaflet suture can be advanced out of the needle to secure the mitral valve leaflet to the leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.
MICRO NEEDLE HOLDER CAPABLE OF CUTTING SUTURES
A micro needle holder capable of cutting sutures, configured for holding needles and cutting sutures during microsurgeries, includes a needle holding unit and a suture cutting unit. The needle holding unit includes a pair of first plier bodies and a first shaft, where each of the first plier bodies has a needle holding end, a first shaft connecting part, and a first plier arm. The suture cutting unit includes a pair of second plier bodies and a second shaft, where each of the second plier bodies includes a suture cutting end, a second shaft connecting part, and a second plier arm. Moreover, the first plier arms are respectively connected with the second plier arms and are configured to elastically open and close corporately.
Purse suturing device for hollow viscus
A purse suturing device includes a circular stapler having a tubular stapler head adapted to be inserted inside a section of the hollow viscus to be sutured, a handle with an actuator connected to the stapler head, and an anvil against which the staples may be folded. The anvil has a pole adapted to be inserted into the tubular stapler head. A suturing thread is wound around the hollow viscus and tightened, causing a section of the hollow viscus to be tightened around the pole. The tightened section also includes a pursed, or folded, section of the wall of the hollow viscus, in which two layers of the wall of the hollow viscus are stapled together.
