Provided is a system, a device, a cassette for use therein and method for suturing two tissue sections, for example two sections of a tissue, by using a plurality of consecutively-arranged anchoring units.

The present disclosure relates generally to the field of medical devices for delivering artificial chordae tendineae in a patient. A system for adjusting tension in an artificial chordae tendineae includes an artificial chordae tendineae coupleable between a clip and an anchor. The clip is engageable with a leaflet of a heart valve while the anchor is engageable with a papillary muscle or heart wall. The anchor includes a body portion, and a locking portion coupleable with the artificial chordae tendineae and configured to allow movement of the artificial chordae tendineae in a first direction while preventing movement of the artificial chordae tendineae in a second direction opposite the first direction. An actuator is coupled to the locking portion for selectively releasing the locking portion to enable selective movement of the artificial chordae tendineae in the second direction.

An anchor for attaching injured soft tissue to a bone and generating a therapeutic electromagnetic field at least in a part of the soft tissue when the soft tissue is sutured to the anchor, the anchor comprising: a) an affixing portion configured for affixing the anchor to the bone; b) a coil that generates the electromagnetic field when a current runs through it; c) an electronics module that controls the current in the coil; and d) an electric power source that provides electric power to the electronics module and the coil.

Syndesmosis fixation assemblies, systems, and methods thereof. A syndesmosis fixation assembly includes a suture retaining portion having a plurality of suture openings formed therein and a suture securing portion rotatably connected to the suture retaining portion. The suture securing portion is movable between a first position wherein a suture is moveable within the suture retaining portion and a second position wherein the suture is frictionally secured within the suture retaining portion. A bone insertion portion has a distal bone insertion end adapted for insertion into a bone, a proximal bone insertion end connected to the suture retaining portion, and a central longitudinal axis extending between the distal bone insertion end and the proximal bone insertion end.

Bone anchors and bone anchor insertion systems are provided that enable smaller bone holes for inserting a bone anchor by eliminating the need for a cannula. Smaller bone holes may help reduce patient recovery times. The provided bone anchor includes two flexible wings extending from a base portion that splay away from the base portion's central axis at rest, though may be bent towards or away from the central axis in response to an applied force. The bone anchor includes a drive feature that enables an inserter to couple and decouple to the bone anchor. A surgeon may drive the bone anchor through a bone hole via the coupled inserter while the bone hole maintains the bone anchor in a compressed state, and may decouple the inserter when the bone anchor is properly positioned, thereby eliminating the need for a cannula.

The present invention provides knotless suture anchor systems and devices for attaching soft tissue to bone. The systems and devices include suture anchors configured to engage and fasten sutures using set screws such that the locked sutures are free from frictional engagement with bone, screw threading, or internal walls of the anchors and set screws. Fastened sutures may also be re-tensioned by loosening a set screw to unfasten the sutures, adjusting the positioning of the sutures, and tightening the set screw to refasten the sutures. In some embodiments, the systems and devices enable the insertion of a suture anchor without preloading sutures, such that one or more sutures may be fastened to the suture anchor after implanting the suture anchor into a subject.

A catheter device is described. The device is for implanting a leaflet anchor (10) into the heart as part of a procedure for implanting an artificial chordae line (14). The catheter device comprises: a leaflet anchor (10) for attachment to the leaflet (12) of the heart; and a leaflet anchor deployment mechanism (6), (30), (38) for deploying the leaflet anchor (10). The leaflet anchor deployment mechanism (6), (30), (38) allows for retraction and repositioning of the leaflet anchor (10) after deployment of the anchor (10) into the leaflet (12) via an ejector unit (36) having a grasping device (50) with a first configuration arranged to permit deployment of the leaflet anchor (10) into the leaflet (12) without disengagement of the leaflet anchor (10) from the ejector unit (34), and a second configuration in which the leaflet anchor (10) is reversibly released from the ejector unit (36). In the first configuration the grasping device (50) of the ejector unit (36) grasps a proximal end of the leaflet anchor (10), whilst a distal end of the leaflet anchor (10) is unimpeded by the grasping device (50) to enable it to be implanted in the leaflet (12). In the second configuration the grasping device (50) is disengaged from the leaflet anchor (10).

A septal closure device includes a frame comprising one or more tissue anchor features, an occluding membrane, and a pressure sensor device attached to the occluding membrane.

A suture delivery system is described. The system includes an anchor and a cooperating driver, the driver facilitating a delivery of the anchor into the abdominal cavity. The system allows for the deployment of a suture internally into an abdominal wall.

A catheter device is described. The device is for implanting an artificial chordae line (14) in the heart. The catheter device comprises: a leaflet anchor (10) for placement in a leaflet (12) of a heart valve, wherein the leaflet anchor (10) is arranged to be coupled to the artificial chordae line (14); and a leaflet anchor deployment mechanism (6, 30, 38) for deploying the leaflet anchor (10), wherein the leaflet anchor deployment mechanism (6, 30, 38) comprises a mechanical gripper device (30, 32, 32′), for grasping the leaflet (12), wherein the gripper device (30, 32, 32′) comprises a leaflet anchor tube 38 for housing the leaflet anchor (10) in a folded configuration. The gripper device (6, 30, 38) and the leaflet anchor (10) are arranged such that when, in use, the gripper device (6, 30, 38) grasps the leaflet (12), the leaflet anchor (10) can be pushed out of the leaflet anchor tube (38) to pierce the leaflet (12) and form the leaflet anchor (10) into an unfolded configuration so that hooked formations of the leaflet anchor (10) can, in use, secure the leaflet anchor (10) in the leaflet (12). The mechanical gripper device (6, 30, 38) includes a first gripper arm (30) rotatably coupled to a main body (4) of the catheter device so that the gripper arm (30) can rotate relative to the catheter device to move an outer end (42) of the first gripper arm (30) away from the main body (4) of the catheter device and a second gripper arm (32, 32′) rotatably and/or slideably coupled to the main body (4) of the catheter device so that the second gripper arm (32, 32′) can rotate and/or slide relative to the main body (4) of the catheter device to move an outer end 46 of the second gripper arm (32, 32′) away from the main body (4). The first and second gripper arms (30, 32, 32′) are arranged so that they can move to come into contact with one another at a point spaced apart from the main body (4) of the catheter device.
