The transparent window is mounted for movement between a first position in general alignment with the longitudinal axis of the obturator sleeve and a second position radially displaced from the longitudinal axis to thereby expose the longitudinal bore of the obturator sleeve to permit passage of the surgical instrumentation. The transparent window may include a cutting blade, or alternatively two cutting blades, adapted to penetrate tissue.

  • Patent number: 11540917
    Abstract: A system for fracturing a frame of a deployed prosthesis with ultrasonic vibration includes a shaft, a tip assembly, an ultrasonic electric generator, and an ultrasonic transducer. The shaft includes a proximal portion and a distal portion. The tip assembly is coupled to the distal portion of the shaft. The tip assembly includes a cutting edge. The ultrasonic transducer is electrically coupled to the ultrasonic generator. Ultrasonic vibration generated by the ultrasonic transducer is translated to the tip assembly. The cutting edge of the tip assembly is configured to focus the vibration of the tip assembly onto a frame of a deployed prosthesis to fracture the frame of the prosthesis. The ultrasonic transducer may be coupled to the proximal portion or the distal portion of the shaft.

  • Patent number: 11534179
    Abstract: Described herein is an anti-skid surgical instrument for use in preparing holes in bone tissue. The disclosed surgical instrument provides the ability to prepare a precise hole in bone tissue during surgery (e.g., spinal surgeries and pedicle screw placement, intramedullary screw placement). The disclosed surgical instrument accomplishes precise hole placement regardless of whether the angle between the drill axis and surface of the bone tissue is perpendicular. The disclosed technology includes a flat drilling surface which is perpendicular to the surface of the body of the surgical instrument. This reduces the likelihood of the surgical instrument skidding on the surface of the bone tissue and thereby increases the precision of the hole.

  • Patent number: 11523837
    Abstract: A method and device for perforating an aortic valve to remove excessive calcium deposits on aortic valve leaflets improves the implantation of TAVI replacement valves in patients. By removing excessive calcium deposits, the radial pressure exerted by implanted TAVI replacement valves is reduced, such that there is less blood leakage around the valve and less stress on the cardiac conductive system. A device with a collapsible punch is inserted into the aortic valve. The punch is separable such that the aortic valve leaflets are positioned between at least two elements of the punch. The two elements then compress together with the leaflets between them, causing the aortic valve to be perforated. A circumferential ring of the remaining aortic valve and calcium deposits are left to provide stability for the TAVI replacement valve.

  • Patent number: 11517447
    Abstract: An apparatus for releasably holding a surgical tool having a body, the body having a longitudinal axis, a monolithic construction, and a shape apportioned to be grasped by a human hand, with body further having a tool engaging portion, a hand receiving portion, and a button pressing portion. A longitudinal bore is disposed along the longitudinal axis of the body, and on one end. A transverse bore is disposed through the body into the longitudinal bore, with the transverse bore disposed such that the longitudinal axis of the transverse bore intersects the longitudinal axis of the longitudinal bore. A button disposed on and pivotably attached at a resilient member to the button pressing portion of the exterior of the body, with the button being proximal to the tool engaging portion. The button has a button bore and a boss extending from the button bore into the transverse bore which is alignable with the longitudinal bore.

  • Patent number: 11497519
    Abstract: A bone cutting surgical instrument includes features to mitigate heat generation during use. Excessive heat can be detrimental to bone health as well as to the instrument itself. In one example a liquid dispensing feature provides a flow of cooling liquid to an ultrasonic blade via a lumen in a waveguide of the instrument. In another example, the blade has a serrated edge with a plurality of teeth arranged in a pattern to provide dimension and space during cutting actions. In another example, the blade has an oversize distal portion that creates an oversize slot when cutting to avoid excessive contact between the cut bone and proximal portions of the blade. In another example the blade includes an irrigation slot and also a micro slot in a distal end of the blade that connects with the irrigation slot.
