20120016482 | PROSTHETIC KNEE VOID FILERS WITH SPLINED FIXATION - Disclosed herein are systems and methods for filling bone voids which may be present at the time of surgery. The systems disclosed herein generally include a baseplate component, a spacer component, and void filler component. The spacer component is generally assembled to the baseplate component with a taper or press-fit, for example, in one of a plurality of selected axial positions. The void filler component is then generally assembled to the spacer component in one of a plurality of selected axial positions. The void filler component preferably has an outer surface with portions having varying diameters such that the outer surface thereof can be received within a canal of a bone and contact the bone forming the canal at different locations in order to aid in stabilizing the assembled components in the canal. | 01-19-2012 |
20120191137 | PERCUTANEOUS COMPRESSION AND DISTRACTION SYSTEM - A compression and distraction shaft assembly applies compression and distraction to bones including vertebrae. Shaft A assembly and shaft B assembly are attached together via a polyaxial fulcrum. The polyaxial fulcrum allows all rotational degrees of freedom between shaft A assembly and shaft B assembly. Such fulcrum, during compression and distraction, does not impart ancillary stresses or motion to vertebrae. An hourglass-shaped bore for engaging pliers is formed in approximately middle of both the shaft A assembly and the shaft B assembly. Distraction pliers having cylindrical tips are used to apply distraction to vertebrae. Once handles are pressed to impart an appropriate amount of distraction to the vertebrae, they are locked in this position. Compression pliers having cylindrical tips are used to apply compression to vertebrae. Once handles are pressed to impart an appropriate amount of compression to the vertebrae, they are locked in this position. | 07-26-2012 |
20120197282 | Methods for facilitating tissue puncture - A method is disclosed for facilitating tissue puncture of a portion of biological tissue using a device, the device comprising a tissue supporting member that is adapted to be placed in a proximal position relative to a portion of the biological tissue and a tissue puncturing member that is adapted to be placed in a distal position relative to the portion of the biological tissue, so that the portion of biological tissue is between the tissue supporting member and tissue puncturing member, the method comprising: supporting the portion of biological tissue using the tissue supporting member; and advancing the tissue puncturing member in a distal direction such that the tissue puncturing member passes through the portion of the biological tissue, thereby puncturing the portion of biological tissue. | 08-02-2012 |
20130046319 | Medical Device Having a Position Indicator - A medical device is described, the medical device comprising a moveable member, moveable between a first position and a second position; an actuating member coupled to the moveable member, directly or indirectly, for manipulating the moveable member, that is for causing the movement of the moveable member; and an indicator coupled, directly or indirectly, to the actuating member, said indicator having a first state and a second state; the indicator and actuating member being cooperatively operable such that the indicator automatically transitions between the first state and the second state to indicate advancement of the member to the second position from the first position upon a predetermined actuation of the actuating member. | 02-21-2013 |
20130150858 | SURGICAL REAMING INSTRUMENT FOR SHAPING A BONE CAVITY - Disclosed herein are systems and methods for shaping bone voids during revision procedures of total knee replacements. The systems disclosed herein generally include a cannulated reamer assembly, a reaming guide assembly, a guide tube assembly, a trial stem assembly, and an optional insertion/removal tool. Metaphyseal reconstruction devices can be used to fill the bone voids in conjunction with the systems and methods disclosed herein. | 06-13-2013 |
20130178898 | TISSUE APPROXIMATION - Systems and methods for approximating tissue using suture are described. The systems include at least one suture with a locking portion that is integral to the suture. The locking portion may be an expanded portion of the suture body. The locking portion may receive a plurality of snares that work to carry the at least one end of the suture through the locking portion. The systems may also include suture anchors and external locking mechanisms such as a tubular sheath. The systems may be used to approximate two soft tissue portions together, or a soft tissue and a bone portion together. | 07-11-2013 |

20140180313 | Suture Passing Instrumentation and Methods of use Thereof - The instant disclosure is directed to methods and devices for passing suture bi-directionally using a hybrid approach. Embodiments of a method described herein include steps of advancing a suture at least partially through tissue; and retrieving the suture; wherein one of the steps of advancing and retrieving comprises manipulating the suture directly, and wherein the other step of advancing and retrieving comprises manipulating a suture trap to which the suture is coupled. Embodiments of a device that may be used to practice the method embodiments include a bi-directional suture passer having a proximal portion for holding a portion of a suture therein; a distal tip coupled to the proximal portion and defining a tissue receiving gap there-between; a reciprocally moveable suture passing member housed within the proximal portion for translating the suture portion between the proximal portion and the distal tip; and a suture trap operable to be detachably coupled to the distal tip for capturing the suture passed by the suture passing member. | 06-26-2014 |
