  • Patent number: 11406488
    Abstract: Systems and methods for providing fixation of soft tissue (for example, ligament) to bone by employing a novel multi-piece device. The novel multi-piece device is a ligament fixation system consisting of a larger collar that is initially impacted into a bone aperture, and a smaller plug/bullet-shaped part that is impacted into the larger collar. During ligament repair/reconstruction, the graft is inserted into a bone tunnel with sutures from the graft extending outside the tunnel. The sutures are passed through a collar of the multi-part device and the collar is then inserted into the bone tunnel. The graft suture strands may be tensioned. Subsequently, the smaller plug/bullet-shaped part is impacted into the collar thereby maintaining the tension on the graft sutures. The plug/bullet-shaped part is tightened after the desired tension on the suture is achieved.

  • Patent number: 11253297
    Abstract: A pin made of cortical bone may be inserted into adjoining bones of a toe to align and secure the bones. The pin may have barbs to prevent migration of the pin. The pin may include a shoulder to further prevent migration of the pin from the bones, to increase the strength of the pin, and to increase the surface area between the bone pin and the host bone. The pin may further include flattened portions on its circumference to aide in rotating the pin during insertion. The pin may be treated to reduce brittleness.

  • Patent number: 11253723
    Abstract: An osseointegrated fixture of a percutaneous osseointegrated prosthesis (POPs) anchors directly into a bone of a residual limb within an amputation stump. By anchoring directly into the bone, the POPs provides improved mobility, comfort, and function for an amputee, but an interface between an opening in the skin and the osseointegrated fixture, which allows the anchoring directly into the bone, is prone to infection by microbes. An anti-microbial device can be attached to and/or embedded within an extracorporeal portion of the osseointegrated fixture to irradiate at least a portion on the interface with at least one wavelength of light selected for its antimicrobial effects.

  • Patent number: 11246697
    Abstract: A method and apparatus is provided for creating an internal reconstruction tissue graft. Templates may be used to create a multitude of patterns in a variety of tissue reconstruction grafts. An apparatus may be used to create an internal tissue graft for reconstruction through either compression and/or removal of segments. An apparatus may be used, through either compression and or removal of segments of a preformed template made of synthetics and or metal that mirrors a template that can be used as an internal tissue graft for reconstruction. In a method, such as using software analysis and an apparatus, the physical properties of the tissue graft and its pre- and post-operative properties and appearance may be measured.

  • Patent number: 11207153
    Abstract: The present invention is a surgical guide for guiding the insertion of a dental implant into a desired location in a patient's mouth. The implant includes a non-rotational structure. The surgical guide includes a structure and a master tube. The structure has a negative impression surface to be fitted on and placed over gingival tissue, bone, and/or teeth in the patient's mouth. The structure includes an opening through which the dental implant is placed. The master tube is located at the opening. The master tube includes indicia for alignment with the non-rotational structure on the implant such that the non-rotational structure of the implant is at a known angular orientation with respect to the master tube. The present invention includes kits of various components used with the surgical guide and with the dental surgery using the surgical guide.

  • Patent number: 11207157
    Abstract: The invention relates to a scan abutment (2), in particular an integrally manufactured scan abutment, for determination of the position of the front face (1.1) of a dental endosseous implant (1), wherein the abutment (2) has a longish, hollow shaft (4), and the shaft has an upper region (4.1), a central region (4.2) and a lower region (4.3). Moreover, the shaft (4) of the scan abutment with its central region (4.2) is attachable onto the front face (1.1) of the implant (1), and its lower region (4.3) is insertable into the connection geometry of the implant. The longish, hollow shaft (4) has a side wall (10). The shaft of the scan abutment has at least two to terminally extending slits (5) in its central region (4.2) and lower region (4.3) in the side wall (10). Two, three or four slits are preferred. Preferably, the slits (5) end in one recess (6) each, such as a circular recess, in the side wall (10) at their upper end and extend terminally in the side wall (10) to the bottom side of the shaft (4).

  • Patent number: 11202693
    Abstract: A dental abutment coping or ring for securing a dental prosthesis to dental abutments. The coping or ring includes a body for insertion into a dental prosthesis, and a cavity or space sized to accept a head of the dental abutment. The interior surface of the cavity includes an interface region sized and shaped to accept the dental abutment in a retentive interface fit or a passive fit, depending on an angle of the interface surface. The exterior surface can have channels configured to contain a cement bonding the exterior surface to the dental prosthesis. A dental prosthesis system including the dental copings provides a retentive interference fit between the prosthesis and the dental abutments, even where the dental abutments are not parallel. A plurality of copings and abutments enables a retentive fit to varying degrees depending on the degree of interference fit in each coping and abutment.
