Methods and devices for repairing and anchoring damaged tissue
Methods and devices are provided for anchoring suture to tissue, incorporating anchoring devices constructed substantially from suture. The anchoring devices are constructed as longitudinally extended, preformed knot configurations that upon deployment are reconfigured to form anchoring knots having an increased cross-section relative to the preformed knot configuration, for secure lodging in tissue. The anchoring devices are suitable for single and multi-anchor surgical procedures in soft tissue or bone, and multiple anchors can be delivered using a single delivery device.
Implant devices with a pre-set pulley system
The problem of positioning one or more nerve ends inside a sheathing implant is solved by the use of a pulley and cinching systems that pull a nerve end into an implant and that can adjust the diameter of an implant to conform the implant to the diameter of the nerve, respectively. The pulley system utilizes a suture that traverses the wall of an implant leaving one end outside the implant wall and another end that can be attached to a nerve. Pulling the suture end outside the wall pulls the nerve attached to the other end of the suture into the bore of the implant. A cinching system utilizes specially arranged sutures within the wall of an implant to tighten or cinch up the wall after a nerve is placed therein, so as to conform at least part of the implant to the diameter of the nerve. Methods are also disclosed by which such pulley systems can be formed during an intraoperative procedure.
Prosthetic incision device and methods thereof
A modular surgical apparatus is disclosed. Also disclosed is a modular incision apparatus. The modular incision apparatus may be used in a minimally invasive surgery. The modular incision apparatus includes a base having a pair of pivots, a pair of alignment tabs, a proximal opening, and at least one slide guide. The modular incision apparatus includes visual and cleaning access to the blade. The modular incision apparatus is suitable for safely, efficiently, and accurately making small incisions during surgical procedures. The modular incision apparatus provides a means of making small incisions of controlled depth, while reducing the chances of inadvertent exposure of surgical staff to sharp instrument.
Robotic surgery system including position sensors using fiber bragg gratings
An apparatus comprises a surgical instrument mountable to a robotic manipulator. The surgical instrument comprises an elongate arm. The elongate arm comprises an actively controlled bendable region including at least one joint region, a passively bendable region including a distal end coupled to the actively controlled bendable region, an actuation mechanism extending through the passively bendable region and coupled to the at least one joint region to control the actively controlled bendable region, and a channel extending through the elongate arm. The surgical instrument also comprises an optical fiber positioned in the channel. The optical fiber includes an optical fiber bend sensor in at least one of the passively bendable region or the actively controlled bendable region.
Adjustable suture-button construct for ankle syndesmosis repair
An adjustable, knotless button/loop construct for fixation of ankle syndesmosis tibio-fibular diastasis and an associated method of ankle repair using the same. The knotless construct comprises a pair of buttons attached to a flexible, continuous, self-cinching, adjustable loop integrated with two splices that are interconnected. The knotless construct is passed through fibular and tibia tunnels and the buttons are secured on the cortical surfaces of tibia and fibula. One of the buttons (for example, an oblong button) is secured on the medial side of the tibia by passing the button and the flexible, adjustable loop though the fibular and tibia tunnels and then flipping and seating the button outside the tibia. The length of the flexible adjustable loop is adjusted so that the second button (for example, a round button) is appropriately secured on the lateral fibula.
Apparatus and methods for Loading Suture
Various embodiments of a cartridge are disclosed, for loading a suture onto a suturing instrument and, in some embodiments, for loading a pre-tied knot formed from the suture onto the suturing instrument. The suturing instrument is typically of the type having a suture passing member defining a suture receiving passage therein. The cartridge may be operable to load the suture and/or the knot onto the suturing instrument at a point of use. In some embodiments, the cartridge defines a path for insertion thereto and withdrawal therefrom of the suturing instrument. The cartridge further comprises a seat for releasably holding a portion of a suture and a mechanism for transferring the suture from seat to the suturing instrument, various features of which are described herein.
Insertion instrument for anchor assembly
An insertion instrument is configured to eject a pair of anchor bodies across an anatomical gap so as to approximate the gap. The insertion instrument can include a single cannula that retains the pair of anchor bodies in a stacked relationship, or a pair of adjacent cannulas that each retain respective anchor bodies. The insertion instrument can be actuated so as to eject the anchor bodies into respective target anatomical locations.
Suture delivery system
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.
Anchored loop-in-loop suture anchor
A system and method for securing a target body to a bone mass with a loop-in-loop suture anchor. The system generally includes suture material passing through a substrate (e.g., suture anchor). The suture material includes a splice that allows the suture material to be passed through the splice and around a target body, ultimately creating three loops in the suture material. By tensioning the loops and/or ends of the suture material, the loops bring the target body into a desired position relative to the bone mass and secure it in that position.
ADJUSTABLE LOOP WITH LOCKING KNOT
Systems, devices, and methods for soft tissue repair are generally provided and they generally involve the use of surgical filaments that are configured in a variety of manners to minimize and/or eliminate the tying of knots during a surgical procedure. Moreover, systems and devices described herein can provide for a reversible locking knot, which allows for additional tension to be applied to the repair if adjustments are required after the construct has been locked. The reversible locking knot can be “flipped” or actuated without requiring the knot to be untied and then retied. Further, systems and devices described herein can additionally be used to associate implantable bodies and suture constructs within a bone to secure soft tissue while not restricting the relative movements of operative sutures once the implantable body has been deployed.
