  • Patent number: 10631849
    Abstract: An anchoring system is a combination of a nanofiber scaffold material and an arthroscopically deployable suture anchor. The anchor is deployed into a bone tunnel using common techniques. The nanofiber material extends out of the proximal end of the implant, once deployed. The implant also includes pre-loaded sutures or has the ability to accept and lock sutures to the implant. For an implant pre-loaded with suture, the implant is placed into the bone, the material is deployed above the anchor onto the surface of the bone, suture is passed through the soft tissue, and knots are tied to secure the tissue against the bone, sandwiching the material between the bone and tissue, to provide a pathway for cells from the bone marrow to the soft tissue-bone interface, promote the healing response, provide a biomimetic structure that cells readily adhere to, and create a larger healing footprint.

  • Patent number: 10433964
    Abstract: A joint prosthesis system is suitable for cementless fixation. The system has two metal implant components and a bearing. One of the metal implant components has an articulation surface for articulation with the bearing. The other metal implant component has a mounting surface for supporting the bearing. One of the metal implant components includes a solid metal portion and a porous metal portion. The porous metal portion has surfaces with different characteristics, such as roughness, to improve bone fixation, ease removal of the implant component in a revision surgery, reduce soft tissue irritation, improve the strength of a sintered bond between the solid and porous metal portions, or reduce or eliminate the possibility of blood traveling through the porous metal portion into the joint space. A method of making the joint prosthesis is also disclosed. The invention may also be applied to discrete porous metal implant components, such as augment.

  • Patent number: 10299806
    Abstract: A bone clamp having a first jaw, an opposed second jaw and a drill guide, the drill guide being attached to the first jaw so that bone held between the first jaw and the second jaw can be drilled by a drill inserted through the drill guide, the first jaw having a longitudinal axis. The drill guide can be ball shaped at one distal end thereof that is positioned sufficiently within and retained within a corresponding cavity of the first jaw so that the angle of the drill guide can be adjusted to compound angles in the longitudinal and transverse directions in relation to the longitudinal axis of the first jaw. The bone clamp preferably comprises an organic polymer that is relatively transparent to X-rays.

  • Patent number: 10155066
    Abstract: A hardenable multi-part acrylic composition comprises a solid first part and a storage stable liquid second part and optionally, further solid and/or liquid parts, the parts being operable to form a cement which hardens to a solid mass upon mixing. The composition further comprises an acrylic monomer component in the second part, an initiator component, a first sub-population of acrylic polymer particles in the first and/or further parts, a second sub-population of acrylic polymer particles in the first and/or further parts and optionally, one or more further sub-population(s) of acrylic polymer particles, and a radiopacifying filler. The initiator component amount is effective to polymerize the acrylic monomer component upon mixing. At least some of the radiopacifying filler is encapsulated within and/or adsorbed on the first sub-population of acrylic polymer particles and the second sub-population of acrylic polymer particles has a lower average particle size than the first.

  • Patent number: 10098743
    Abstract: A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of a cavity of a bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the support structure by an adhesive. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining the channel between the pair of components.

  • Patent number: 9649410
    Abstract: A metal implant for use in a surgical procedure is provided with a surface layer that is integral with the metal substrate, and which incorporates a biocidal material. The surface layer may be grown from the metal substrate, by anodising, and the biocidal material incorporated in it by ion exchange. Alternatively the layer may be deposited by electroplating, followed by diffusion bonding so as to become integral with the metal substrate. In either case, silver is a suitable biocidal material; and both the release rate and the quantity of biocidal material should be low to avoid toxic effects on body cells. Electropolishing the surface before formation of the surface layer is also beneficial, and this may be achieved by electropolishing.
