Medical devices and connector assemblies for connecting medical devices are disclosed. An example connector assembly for connecting a robotic arm with a medical end effector may include a plate configured to be coupled to a robotic arm. The plate may have a connection region that includes a flange defining a circumferential groove. The connector assembly may also include an attachment assembly having an attachment region configured to be detachably secured to the connection region with a securing distance of less than 12 millimeters. The attachment region may include one or more engagement members that are configured to shift between an unsecured position and a secured position where the engagement members are secured to the connection region. An actuator may be coupled to the attachment assembly for shifting the one or more engagement members between the unsecured position and the secured position.

The present invention relates to an implantable anterior cervical plate having a stackable superior design, which deflects soft tissue.

A plate and cage assembly for stabilization of vertebral bodies. The assembly includes at least one fixation member, a cage having a proximal wall, a superior surface and an inferior surface (the superior surface and the inferior surface for engaging adjacent vertebrae), and a plate coupled to the cage and having at least one hole traversing the plate at an angle for insertion of the at least one fixation member into one of the vertebral bodies. The proximal wall of the cage has a blind hole, and the plate has a threaded screw hole aligned with the blind hole in the proximal wall of the cage.

A nuclear disc implant includes an inner fillable enclosure and an outer fillable enclosure. After insertion into a enucleated disc cavity, the inner enclosure is filled with a fluid and the outer fillable enclosure is filled with a curable material. The curable material is allowed to cure and the fluid is removed from the inner enclosure to leave an inner enclosure surrounded by an cured outer enclosure. A reinforcing band may be provided around the nuclear disc implant. An inflation tool to fill the nuclear disc implant is provided.

A method for implanting an intrafacet implant includes making an incision, advancing an instrument assembly through the incision and to a facet joint. The instrument assembly includes a guide having a lumen extending therethrough. The method includes anchoring the guide at the facet joint, advancing an intrafacet implant to the facet joint through the guide using an inserter, and countersinking the intrafacet implant within the facet joint using the inserter.

A multi-member prosthesis including first and second elongated members and a central member, said multi-member prosthesis adapted to be advanced into a pilot SI joint opening in said dysfunctional SI joint via a posterior approach, the pilot SI joint opening comprising a sacrum opening and an ilium opening and a sacrum opening. The first elongated member adapted to be press-fit into the sacrum opening and the second elongated member adapted to be press-fit into the ilium opening. The central member including first and second elongated member securing means adapted to secure the first and second elongated members thereto.

An interbody spinal cage comprising: a body portion comprising a superior side, an inferior side and at least one lateral side connecting the superior side and the inferior side; and at least one endplate portion coupled to the superior side or the inferior side of the body portion, the at least one endplate portion comprising a unibody structure and operable to be fixedly coupled to an anatomical structure of a patient and decoupled from the superior side or the inferior side of the body portion.

A system and method for providing a surgical instrument having a shaft with a proximal end, a distal end, a longitudinal axis, and a central lumen extending therethrough; and a tapered head at the distal end. The tapered head has a plurality of longitudinal channels, a plurality of threaded sections, and a plurality of lateral lumens. The plurality of longitudinal channels may form a plurality of flutes configured to cut bone, tissue, or both.

An inflatable and implantable balloon for treatment of degenerative disc disease, bones, lesions, spinal deformities and spinal motion segment instabilities. The balloon is comprised of adjustable and expandable volumes. Further disclosed are methods of forming, inserting, expanding, and implanting the multi-volume balloon for proper placement and stabilization of the spinal lesion or disease. Still further disclosed are kits for aligning and stabilizing elements of the spine.

A method and system for determining an extent of matter removed from a targeted anatomical structure are disclosed. The method includes acquiring an initial representation of a targeted anatomical structure and then removing matter from the targeted anatomical structure. An instrument is then navigated within the targeted anatomical structure. The instrument includes a tracking array, and a relative position of the instrument within the targeted anatomical structure is determined by the tracking array. The method includes recording the relative position of the instrument within the targeted anatomical structure to determine a final representation of the targeted anatomical structure. Finally, the method includes determining an extent of matter removed from the targeted anatomical structure by comparing the initial representation of the targeted anatomical structure with the final representation of the targeted anatomical structure. Indicators are provided to convey the extent of matter remaining within the targeted anatomical structure.
