摘要： A system, for use with a leaflet of a valve of a subject's heart, comprises a catheter, a cutting device, a helical needle, and a suture. The catheter is transluminally advanceable toward the heart. The cutting device is advanceable distally out of the catheter, and is adapted to cut through tissue of the leaflet to form cut tissue and cut edges at the cardiac valve. The helical needle defines a helical lumen, the helical needle configured to be advanced distally out of the catheter and to rotationally extend through, and secure together, two tissue segments of the leaflet. The suture extends through the helical lumen of the helical needle. The helical needle and the suture are configured to extend along the two tissue segments of the leaflet to suture the two tissue segments to each other. Other embodiments are also described.

摘要： Devices, systems and/or methods for repairing soft tissue adjacent a soft tissue repair site. In one embodiment, the repair device includes an anchor member having a base with at least four legs extending from the base. The base extends with a generally flat circular profile defining an upper surface and an underside surface with a central opening extending therethrough. Further, the at least four legs extend from the base with an elongated angled portion, the elongated angled portion being oriented at an angle less than seventy-five degrees relative to the underside surface of the base. With this arrangement, the anchor member may be fixated to soft tissue by rotating the base with a delivery tool so that the elongated angled portion of the at least four legs facilitates the anchor member sinking into the soft tissue and fixating thereto.

摘要： A system for repairing a meniscus includes a suture that includes a first anchor, a second anchor, and a flexible portion connecting the first anchor and the second anchor. The flexible portion includes a self-locking slide knot between the first anchor and the second anchor. The system also includes a needle having a longitudinal extending bore and an open end. The bore is configured to receive the first anchor and the second anchor. The system further includes a body portion operatively connected to the needle at a distal end of the body portion. The body portion has a lumen. The system also includes a pusher configured to rotate and slide within the lumen of the body portion and the longitudinal extending bore of the needle. The pusher has first and second stop surfaces, each of which is constructed and arranged to engage a proximal end of the body portion.

摘要： Apparatus and methods are provided, including a plurality of anchoring elements, each of the anchoring elements being an elongate element that is curved to define an opening. A housing holds each of the anchoring elements. A mandrel is reversibly disposable through the openings defined by the anchoring elements. The anchoring elements are configured such that, in response to removal of the mandrel from the openings, ends of the anchoring elements automatically move outwardly, and diameters of the openings decrease, due to elastic loading of the anchoring elements. Other embodiments are also described.

摘要： 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.

摘要： A method comprises advancing an elongate tube to a target implantation site, the elongate tube having a needle disposed at least partially therein that has a coiled sutureform wrapped around at least a portion thereof, contacting a distal end of the elongate tube to a target tissue, projecting a tip of the needle from the distal end of the elongate tube to pierce through the target tissue such that the tip of the needle and at least a portion of the coiled sutureform project through the target tissue, advancing a pusher device within the elongate tube and over the needle to push the at least a portion of the coiled sutureform off of the tip of the needle, and proximally pulling one or more suture tails associated with the coiled sutureform to form the coiled sutureform into a knot on a distal side of the target tissue.

摘要： Devices, systems and methods for compressing, cutting, incising, reconfiguring, remodeling, attaching, repositioning, supporting, dislocating or altering the composition of tissues or anatomical structures to alter their positional or force relationship to other tissues or anatomical structures. In some applications, the invention may be used to used to improve patency or fluid flow through a body lumen or cavity (e.g., to limit constriction of the urethra by an enlarged prostate gland).
