  • Patent number: 10966842
    Abstract: Devices and methods for the removal of bone implant tips from within a bony structure in a body. The device or method includes a shaft with an internal grasping feature capable of being inserted while remaining in an un-expanded, un-deployed state. This permits a surgeon or operator to insert the device while in a small profile state, avoiding or reducing damage to adjacent bone tissue during insertion. Upon insertion of the shaft to the proper position within a patient's bone, the grasping feature may then be expanded or deployed from the distal end of the shaft by a surgeon or operator using an actuator in a handle attached to the proximal end of the shaft. Following deployment, the grasping feature may be used to manipulate and/or remove a bone implant tip from a patient's bone tissue. Embodiments of the grasping feature include one or more hooks, wires, articulating fingers, and/or net-based designs formed of metal, polymer, composite, or a combination thereof.

  • Patent number: 10555732
    Abstract: Described herein are reusable surgical needles having a resiliently collapsible rear loop that captures a suture as it is passed through an object and resiliently expands upon exiting the object to release the suture. Also described are suture spool assemblies that include a rigid housing and a rotatable spool of suture material suspended within the housing so that a plurality of sutures can be dispensed from the assembly in succession during a surgery. Also described are annular pledgets having diametrical dimensions similar to an outer ring of a cardiac implant such that a single annular pledget can be used with a plurality of sutures that secure the cardiac implant to native tissue around the perimeter of the cardiac implant. Related methods of suturing cardiac implants are also disclosed.

  • Patent number: 10537447
    Abstract: Spinal implant trials are provided having various configurations and sizes that aid the selection of spinal implants having similar configurations and sizes. A surgeon during surgery can insert various configurations and sizes of the spinal implant trials into a disc space between two adjacent vertebral bodies of a patient to enable the selection of a spinal implant configured and sized to fit the patient's disc space. Fluoroscopic images can be used in aiding the selection of an appropriately configured and sized spinal implant corresponding to one of the spinal implant trials. The spinal implant trials include features that reveal on the fluoroscopic images whether the spinal implant trials are properly located and oriented in the disc space and include features corresponding to different sizes of spinal implants also revealed on the fluoroscopic images.

  • Patent number: 10524842
    Abstract: Methods, systems and apparatuses are provided for torsionally stabilizing a spinal motion segment. One or more implants are placed between two vertebrae to provide torsional stabilization. In particular, one or more implants may be fixed between a superior vertebral body, such as at the spinous process, and an inferior vertebral body. The implants may be connected to the superior vertebral body using a fixation device such as a turnbuckle, an outrigger, a thimble, an endobutton, a suture plug or combinations thereof. The implant may also be connected to the inferior vertebral body using various types of hardware, including staples, screws and anchors. The implant may be kept in tension to provide torsional stabilization and may be comprised of one or more sutures. A multi-functional instrument having one or more arms having holes can be used to clamp onto the superior vertebral body and guide one or more implants to various locations for fixation in accordance with the methods described herein.

  • Patent number: 10524925
    Abstract: A system for fusing together opposing vertebra of a spine that defines a disc space therebetween. The system comprises a disc preparation instrument and an inserter assembly for use in the interbody fusion procedure. Disc preparation instrument comprises an elongate handle supporting a trial device at one end thereof. Inserter assembly comprises an elongate inserter supporting at one end thereof an interbody cage implant for insertion into the disc space. Disc preparation instrument provides a scoring element that scribes vertebral endplates at an appropriate scored location for anchor blades on the cage implant to engage the vertebral bodies. Inserter is used to introduce cage implant with anchor blades into the disc space to an appropriate depth so that the blades will be precisely positioned at the scored location created by the scoring element for penetration into the vertebral endplates.

  • Patent number: 10492927
    Abstract: A cup impactor (1, 1?, 1?) is provided, adapted to assist a surgeon in controlling implantation of a cup prosthesis (9). The impactor has an impactor body (8), a drive train assembly (71), an impactor nose (38), and a clamping handle (5). The impactor body (8) has on its proximal end, an impaction plate (7) connected thereto, and an impactor handle (6) formed thereon for handling by the surgeon and, on the distal end, an impactor cup support portion (8a) having a receiver recess (8b) therein. A drive train assembly (71) has a prosthesis engaging interface (11) at a distal end thereof, and a proximal end on which a positioning knob (2) is formed. The assembly (71) received and rotatably mounted in the receiver recess (8b) of the body (8) so as to expose the prosthesis engaging surface (11). An impactor nose (38) mounts on the distal end of the impactor body (8), through which the prosthesis engaging interface (11) extends.

  • Patent number: 10449031
    Abstract: An implant delivery system for delivering a sheet-like implant is disclosed. The device includes an implant spreader assembly disposed proximate the distal end of a delivery shaft. The implant spreader assembly includes a first arm and a second arm. The arms are coupled to the delivery shaft such that the first arm and second arm are moveable between a closed position and an open position. When the first and second arms are in the closed position, the arms extend generally in the longitudinal direction. When pivoting to the open position the distal end of each arm travels in a generally transverse direction to spread a sheet-like implant.

  • Patent number: 10433972
    Abstract: An adjustable implant includes a telescopic body with first and second portions in sliding engagement, and a deflectable linkage formed from a first linking segment, an intermediate segment and a second linking segment pivotally interconnected so that adjustment of a length of the telescopic body causes a corresponding deflection of the deflectable linkage. The first linking segment and the second linking segment are formed with projecting features that provide a partial gear engagement between the first and second linking segments such that, during adjustment of a length of the telescopic body and corresponding deflection of the deflectable linkage, pivotal motion of the first and second linking segments relative to the intermediate segment about the first and second pivot axes occurs in a fixed ratio defined by the partial gear engagement.
