An integrated surgical anchor/localization sensor is disclosed. The anchor is adapted to be secured to an anatomical structure and contains a sensor housing. A receiver is located within the sensor housing and is adapted to sense reference signals generated by a surgical guidance system. A transmitter, connected to the receiver, conveys to a processor signals received by the receiver, so that the signals transmitted by the receiver are indicative of a current position of the anchor. Various other structures and methods are also disclosed.

One or more anchors being disposed in a substantially closed pre-deployment configuration inside the tubular body are configured for being delivered and deployed into a target tissue while remaining in a substantially closed configuration, and assuming its open anchoring properties only once embedded in tissue.

Embodiments of the present invention relate to systems and methods for assisting a user during delivery of a labral anchor. For example, one embodiment provides a labral anchor delivery system that includes a drill sleeve having a proximal end and a distal end that is cannulated therebetween. At least a portion of the drill sleeve proximate to the distal end is curved such that the distal end is configured to be positioned substantially perpendicular to a surface of a glenoid. The labral anchor delivery system includes a drill bit having a proximal end and a distal end and configured to be positioned within the cannulated drill sleeve and into engagement with the surface of the glenoid. In addition, at least a portion of the drill bit between the proximal and distal ends of the drill bit is flexible for conforming to the curved portion of the drill sleeve.

A surgical anchor inserter is equipped to receive or hold two or more bone anchors or the like. A corresponding number of ejection mechanisms can be actuated in concert to simultaneously deploy the anchors.

A first extruded member in joined to a molded member to form an integrated component. In one exemplary form, a surgical anchor is overmolded onto the end of an extruded suture to form a suture/anchor system.

A suture anchoring system having an anchor structure through which at least one suture can extend, the anchor being compressible or deformable to anchor the suture, and a method for using the suture anchoring system by attaching one end of a suture to a muscle, ligament or bone; threading the suture through an osteal tunnel; providing a surgical anchor comprising a cuff of deformable material suitably shaped to receive a suture, wherein said cuff, when compressed, tightly grips a suture and forms a point of support, whereby said deformed anchor prevents a suture from being pulled through a drilled osteal tunnel; threading the other end of the suture through the anchor; and deforming said anchor tightly about the suture to form a point of support.

A surgical anchor is provided with one or more anchor holes distributed around the head of the anchor. Each anchor hole is inclined to allow attachment of one or more sutures to the anchor either before, during or after the anchor is seated in a bone. The upper and lower apertures of each anchor hole are chamfered, and the chamfered areas from the anchor hole to the outside edge shall be polished or somehow smoothed to remove sharp edges and rough areas which may cause friction and abrasion to soft tissue or suture material. The lower surface of the anchor head may be angled to further simplify the task of feeding a surgical needle through the anchor hole after the anchor is seated into the bone.

The present invention relates to a surgical anchor delivery system (10) including a delivery device (11) having a shaft (14) and a handle (13), an advancer (15) for advancing a surgical anchor (12) distally along the shaft (14); and a plurality of surgical anchors (12) loaded upon the shaft (14).

Surgical anchors can be utilized to approximate and hold soft tissue in, at, or near a boney insertion site. In some examples, the surgical anchors include a receiving body and a fixation member such as, for example, a fixation screw. The receiving body may include an elongated connecting member and an aperture defined at a distal end of the elongated connecting member. The aperture may be configured to receive a surgical attachment element. Depending on the configuration, the receiving body may be connected to the fixation member via the elongated connecting member such that the fixation member can move relative to the receiving body. Movement of the fixation member relative to the receiving body may allow a user to control and adjust the amount of tension placed on the surgical attachment element, which may enhance the mechanics of a repair operation.

A high aspect ratio surgical anchor comprises a body defined in part along a major longitudinal axis, a fin coupled to the body, and a channel in the body along the longitudinal axis. The channel is configured to receive and removably secure a tip of an introducer therewithin. A slot is provided through the body that is generally parallel to the longitudinal axis, with the slot being configured to receive and pass implantable material therethrough and to secure a portion of the implantable material therein.

During a sEEG (stereo-electroencephalography) intervention into the skull of a patient, there is requirement to drill a large number of trajectories. Typically, instrument stabilisation platforms and robots for protocols requiring only one or two trajectories are rigidly fixed to the skull using surgical anchor members fixed into the skull around the one or two trajectories. However, because sEEG interventions require a large number of trajectories, an impractical number of surgical anchor members need to be fixed into the skull resulting in patient discomfort. Attachment of an intervention platform to all surgical anchor members is not required at once. Accordingly, it is proposed to search for intersection points of the maximum extent of an intervention platform between at least two trajectory entry points on an object of interest of patient, so that at least one surgical anchor member can be shared when the intersection point is at first and the second trajectories. Any reduction in the number of surgical anchor members inserted into a patient reduces risk and discomfort. The positioning of the shared anchor members can be optimised to enable good mechanical stability, and/or optical registration performance. Furthermore, the number of surgical anchor members required for intervention can be reduced. Because the surgical anchor members are sterilised and made from high quality metal, a cost for performing the procedure can also be reduced.

The present disclosure describes surgical anchors and related devices and methods that can be used for surgical bone fracture fixation. Some implementations use a polymeric cored braided suture held in place by anchors on each side of a fracture. In some implementations, the anchors are secured into bone while maintaining high tension (e.g., relative to certain prior art methods) in the suture during the deployment process. Some implementations provide for tensioning (e.g., using a polymeric cored braided suture) to compress the fracture and hold the bone in place, functioning as though the suture has sewn the bone (e.g., fragments or portions) together. This can, for example, provide rigid fixation of a fracture which may be important for healing to occur. The tension preload can provide compression to maintain fixation in the face of tensile and shear loads applied to the bone (e.g., as a result of movement and weight bearing).

Surgical anchor assemblies and method of tissue repair using the same. The surgical anchor assemblies have a cannulated fixation device, an implant configured to be coupled to the fixation device, and a stop mechanism for preventing relative movement between the fixation device and the implant, such that the fixation device and the implant are configured to rotate together, and a flexible strand winds up to reduce any slack in the flexible strand used for the repair.
