  • Publication number: 20230363771
    Abstract: A cannulated retrograde reamer that is adjustable to create tunnels of multiple different diameters. The cannulated retrograde reamer substantially reduces the risk of tunnel malposition and/or misalignment, and can be adjusted to create a range of tunnel diameters, thereby allowing inventory levels to be reduced for a surgical case.

  • Patent number: 11751888
    Abstract: A cannulated retrograde reamer is adjustable to create tunnels of multiple different diameters. The cannulated retrograde reamer has a first tubular shaft and a second tubular shaft disposed about the first tubular shaft. A cutting member is pivotably coupled to the distal end of the first tubular shaft. The distal end of the second tubular shaft is configured to engage and disengage the proximal end of the cutting member by the rotation and axial movement of the second tubular shaft relative to the first tubular shaft to open and close the cutting member. The cannulated retrograde reamer substantially reduces the risk of tunnel malposition and/or misalignment, and can be adjusted to create a range of tunnel diameters, thereby allowing inventory levels to be reduced for a surgical case.

  • Patent number: 11375988
    Abstract: The present invention provides a device for occluding an anatomical aperture, such as an atrial septal defect (ASD) or a patent foramen ovale (PFO). The occluder includes two sides connected by a central tube. In some embodiments, the occluder is formed from filaments that are joined together to define a substantially cylindrical form with openings defining struts. Upon the application of force, the struts deform into loops. The loops may be of various shapes, sizes, and configurations, and, in at least some embodiments, the loops have rounded peripheries. The occluder further includes a catch system that maintains its deployed state in vivo. When the occluder is deployed in vivo, the two sides are disposed on opposite sides of the septal tissue surrounding the aperture and the catch system is engaged so that the occluder closes the aperture.

  • Patent number: 10758252
    Abstract: A retro guidewire reamer includes a cutting member, and a mechanism for moving the cutting member from a closed position to a deployed position in a single manual motion. Once a desired size of a bone tunnel is established, a surgeon uses the reamer to create a primary bone tunnel over a guidewire from the outside in. The surgeon retracts the guidewire, and activates the mechanism to deploy the cutting member within the bone joint to conform to the size of a tendon graft. The surgeon uses the deployed cutting member to create a counter bore through the bone in a retrograde manner. Once the counter bore is drilled, the surgeon activates the mechanism to close the cutting member, allowing the reamer to be withdrawn through the primary tunnel. The retro guidewire reamer can be used to provide more accurate bone tunnel placement during ligament reconstruction surgery.

  • Patent number: 10537320
    Abstract: An arthroscopic needle having partial cuts or serrations along one side of a circular, hollow needle shaft allows the needle to bend, or articulate, by drawing a pull strip bar, defined by a thin strip along the interior side closet to the serrations in the hollow shaft, for compressing along the cuts to draw uncut segments into closer arrangement for curving the needle in the direction of the compressed side. The selectively articulating, or “bendable” needle that curves in response to a rotating knob provides for insertion of surgical attachment anchors in difficult-to-reach areas of meniscal tissue. The disclosed articulating needle has the ability to bend and access more anterior and posterior zones of meniscal repairs than conventional rigid needle approaches.

  • Patent number: 10219872
    Abstract: A thickness gage including a transparent measurement tube configured to receive and be slidingly engaged over a tubular shaft of a retrograde reamer. The tubular shaft has linear graduation marks on its surface for identifying linear measures for use in measuring a thickness of a bridge bone gap. The linear graduation marks are located on the tubular shaft surface such that at least some of the linear graduation marks can be observed through the transparent measurement tube. Each linear graduation mark, when aligned with a proximal end of the measurement tube, provides a linear measure of the distance between a distal end of the measurement tube and a cutting member of the retrograde reamer positioned so that its central axis is disposed at a non-zero angle relative to a longitudinal axis of the tubular shaft. Such a distance corresponds to the thickness of the bridge bone gap.
