TISSUE FIXATION SYSTEM AND METHOD
A tissue fixation system is provided for dynamic and rigid fixation of tissue. A fastener connected with an elongate fastening member, such as a cable, wire, suture, rod, or tube, is moved through a passage between opposite sides of tissue. The fastener is provided with a groove that accommodates at least a portion of the fastening member to reduce the profile during the movement through the passage. The fastener is then pivoted to change its orientation. A second fastener can then be connected with the fastening member. While tension is maintained in the fastening member, the fasteners are secured against relative movement. This may be done by deforming the fastening member, either the first or second fasteners, or a bushing placed against the second fastener.
Suture securing instrument
A suture securing instrument can include a cylindrical body that has an inner circumferential surface, and a securing portion configured to secure a suture. The securing portion can include an outer circumferential surface supported by the inner circumferential surface of the cylindrical body by moving along a longitudinal axis relative to the cylindrical body, and a holding portion configured to hold the suture between the cylindrical body and the securing portion. The holding portion can also include a groove for the suture.
Mechanical suturing device for automated closure of the linea alba of the abdominal wall post midline laparotomy incision
Surgical instruments for surgical suturing, for the purpose of enabling direct vision access, abdominal wall suturing and procedures of minimum invasion of abdominal structure from the surface thereof to deeper layers.
SURGICAL FASTENING DEVICE
Devices and methods for delivering surgical fasteners to a controlled, specific depth in tissue and locking the fasteners closed to provide a secure and reliable attachment. Devices includes a body with a handle with a trigger extending therefrom; a shaft extending from the body; a delivery tip at a distal end of the shaft; a driver member disposed within the shaft; and a fastener with no points, barbs, or sharp edges held at the delivery tip. The fastener is inserted into a fixed depth and locks into a closed loop.
MULTIPLE-FIRING SUTURE FIXATION DEVICE AND METHODS FOR USING AND MANUFACTURING SAME
A multiple-firing clip device includes a hollow shaft defining a lateral opening communicating with an environment and a distal shaft portion between the lateral opening and a distal end opening. A shuttle longitudinally moves on the shaft and comprises a shuttle body defining a lumen surrounding the shaft, a snare, and a snare-extender slide defining a snare track to form a snare travel path in which the snare is disposed from the body and through the track and a portion of the body. The slide moves along a given extent defining a slide distance and a distal end and movement of the slide to the distal end shortens the snare travel path to extend the snare portion through the lateral opening, through the distal shaft portion, and distally out from a distal side of the body longer than the given extent to secure a suture with the snare.
ENDOSCOPIC TISSUE GRASPING SYSTEMS AND METHODS
An endoscopic tissue grasper device includes a flexible tubular member, a flexible shaft extending through the tubular member, a proximal handle for moving the shaft and tubular member relative to each other, and a distal helical coil having a sharpened end for engaging tissue. The tissue grasper is advanced through a working channel of an endoscope, engaged relative to tissue, and retracted to pull tissue into a path of a movable needle coupled at a distal end of the endoscope so that the needle can be passed through the tissue. The needle is preferably provided with a suture so that as the needle is passed through the tissue a stitch is formed.
Clips, Appliers, and Cartridges
A medical device forming method, an applier for manipulating clips, and a cartridge for holding clips are disclosed herein.
SECURING BIDIRECTIONAL SUTURE LOOPS USING COAXIAL FASTENERS
A method and apparatus for securing separate loops of suture with a coaxial mechanical fastener. Separate loops of suture extend from opposite ends of the mechanical fastener. A wire snare facilitates pulling the suture through the fastener. A suturing instrument provides for the infusion of pressurized physiologic solutions into the left ventricle so that the proper replacement suture length can be demonstrated real time prior to crimping the fastener. The instrument incorporates a slotted release site so that the fastener and suture can be released from the device tip once the fastener is secured. A method of securing suture coming from cardiac valve leaflets and or other structures like papillary muscles permits a more atraumatic orientation of the fastener coaxial with the suture strands.
LOCKING DEVICE WITH LOCKING FEEDBACK FUNCTION AND HEART VALVE REPAIR SYSTEM
A locking device is provided. The locking device includes a locking assembly, a handle, and a locking feedback element. The locking assembly is configured to lock a target object. The locking assembly is coupled with the handle. The handle comprises a movable portion and a fixed portion. The movable portion is configured to move relative to the fixed portion to drive the locking assembly to lock the target object. The locking feedback element is movably disposed in the fixed portion, and is configured to cooperate with the movable portion of the handle to feed back whether the target object is locked. The disclosure further provides a heart valve repair system.
Suture clip
Disclosed suture clips include a generally disk-shaped body having an annular outer body, first and second tabs extending radially inwardly from opposing sides of the annular outer body, first and second slots passing through a thickness of the suture clip and separating the annular outer body from lateral sides of the first and second tabs, and the first and second slots include stepped portions configured to align the suture clip on a rail of a clip deployment device. The stepped slots create bracketing surfaces that interface with the rail on which the clips are mounted, such that the bracketing surfaces prevent or limit the freedom of the clips from tilting or shifting relative to the rail. The disclosed clips can also include rounded edges on engagement surfaces of the tabs to minimize particulate formation.
