Tricuspid Valve Repair Using Tension

A method is provided that includes implanting a first tissue-engaging element in a first portion of tissue in a vicinity of a heart valve. A second tissue-engaging element, which is connected to a third tissue-engaging element by a longitudinal sub-member, is implanted in a second portion of tissue of an annulus, and the third tissue-engaging element is implanted in a third portion of tissue of the annulus. A fourth tissue-engaging element is implanted in a portion of a blood vessel that is in contact with an atrium. While the longitudinal sub-member engages the longitudinal member at a junction therebetween, at least a first leaflet of the heart valve is drawn toward at least a second leaflet of the heart valve by adjusting a distance between the portion of the blood vessel and the first portion of tissue in the vicinity of the heart valve. Other embodiments are also described.

DEVICES, SYSTEMS, AND METHODS FOR CLAMPING A LEAFLET OF A HEART VALVE

The present disclosure relates generally to the field of medical devices for clamping a leaflet of a heart valve. In particular, the present disclosure relates to medical devices, systems, and methods for delivering artificial chordae tendineae in a patient. In an embodiment, a system may include a clamp having a plurality of arms at a first end. The plurality of arms may have a closed configuration in which the arms are oriented toward each other, and an open configuration in which the arms are oriented away from each other. A spring portion may be coupled to the plurality of arms at a second end that is configured to bias the arms to the closed configuration. The arms of the clamp may be configured to fixedly engage with a leaflet of the heart valve. The second end of the clamp may be configured to couple to an artificial chordae tendineae.

A method comprises inserting a needle into a ventricle of a heart. The needle is configured to deliver a first anchoring element, a second anchoring element, and a tethering suture to the ventricle. The tethering suture is tethered between the first anchoring element and the second anchoring element. The method further comprises penetrating a first leaflet of a heart valve with the needle, penetrating a second leaflet of the heart valve with the needle, deploying the first anchoring element at a distal side of the second leaflet, retracting the needle from the first leaflet and the second leaflet, deploying the second anchoring element at a proximal side of the first leaflet, cinching the tethering suture to cause a desired amount of valve coaptation, and locking the tethering suture.

Knotless Methods and Constructs for Tissue Repairs and Reconstructions

Surgical constructs, assemblies, and methods for tissue reinforcement with a reinforcement (reinforcing) material.

Endoscopic suturing system

An endoscopic suturing system and method are disclosed as are devices for use with the system and method such as a suture dispenser, a cinch device, and a tissue grasper. In one embodiment the suturing system includes a cap assembly arranged at the distal end portion of an endoscope or guide member, with the cap assembly including a rotatable needle holder. The needle holder is actuated through a transmission element extending outside the endoscope or guide member. A needle capture device may be inserted through a channel of the endoscope or guide member in order to capture a needle held in the needle holder when the needle holder is rotated so that the needle punctures tissue.

Medical implant and method for heart valve repair

A sutureless implant for replacing damaged natural chordae tendineae of a human or possibly animal heart, the implant including a distal implant part, a proximal implant part, and an artificial chord. The distal implant part is configured to fit in a lumen of an implant delivery device and includes a self-spreading portion spreading radially outside when the distal implant part is released from the lumen, the self-spreading portion being capable of anchoring the distal implant part in human muscle tissue. The proximal implant part is configured to fit in the lumen of the implant delivery device and comprises a self-spreading portion spreading radially outside when the proximal implant part is released from the lumen, the self-spreading portion being capable of bearing on a tissue portion of leaflet tissue. The distal implant part and the proximal implant part are connected by the chord.

Knotless instability suture anchor construct and system

An anchor construct having an anchor having a length of suture material passing therethrough, the suture material having a loop strand terminating at a first end and a post strand terminating at a second end, a splice loop formed by first end, a sliding construct formed by the first end and the second end, wherein the sliding construct is configured to adjust the relative position of the splice loop and the anchor. The anchor construct can be deployed by passing the first end through a first body and through the splice, creating a locking loop of a first size around the first body, implanting the anchor into a bone hole, pulling the post strand to decrease the perimeter of the positioning loop to a second size smaller than the first size, and pulling the loop strand to decrease the perimeter of the locking loop to a smaller second size.

DEVICES, SYSTEMS, AND METHODS FOR REPAIRING SOFT TISSUE AND ATTACHING SOFT TISSUE TO BONE

Devices, systems and/or methods for fixating soft tissue to bone are provided. In one embodiment, a repair device for fixating soft tissue to bone with a bone anchor includes a soft tissue anchor and one or more flexible members. The soft tissue anchor includes a base with multiple legs extending from the base. The one or more flexible members are coupled to the base and configured to extend from the base to the bone anchor with a fixed length. With this arrangement, the fixed length of the one or more flexible members is configured to maintain a fixed distance between the soft tissue anchor and the bone anchor such that, as the bone anchor is seated into bone, the one or more flexible members pulls the soft tissue anchor down against the soft tissue to fixate the soft tissue to the bone.
