  • Patent number: 10405987
    Abstract: A method of determining disc space geometry with the use of an expandable trial having endplate-mapping capabilities. An expandable trial is inserted into the disc space and its height is adjusted to obtain the desired decompression and spinal alignment (which is typically confirmed with the use of CT or Fluoroscopic imaging). The endplate dome/geometry dome is then determined by one of the following three methods: a) direct imaging through the trial, b) balloon moldings filled with flowable in-situ fluid (for example, silicon, polyurethane, or PMMA) from superior/inferior endplates or c) light-based imaging through superior & inferior balloons.

Cutting gates are attached to the posts and used to provide cutting paths that can be precisely oriented with respect to the meniscus of the donor bone part using visual alignment without any manual measurements. The graft is affixed to a machining clamp and shaved to appropriately shape the sides and form a radius on the bottom of the graft. A tibia is then prepared by using a drill guide to form a pilot hole and then to drill out a large hole for the graft. The drilled hole is expanded and shaped using a rod guide and chisel and then a rasp. The shaped graft may then be implanted into the shaped hole and sutured in place.

  • Patent number: 9314339
    Abstract: A permanent non-resorbable implant allows surgical replacement of cartilage in articulating joints, using a hydrogel material (such as a synthetic polyacrylonitrile polymer) reinforced by a flexible fibrous matrix. Articulating hydrogel surface(s) are chemically treated to provide a negative electrical charge that emulates the negative charge of natural cartilage, and also can be treated with halogenating, cross-linking, or other chemical agents for greater strength. For meniscal-type implants, the reinforcing matrix can extend out from the peripheral rim of the hydrogel, to allow secure anchoring to soft tissue such as a joint capsule. For bone-anchored implants, a porous anchoring layer enables tissue ingrowth, and a non-planer perforated layer can provide a supportive interface between the hard anchoring material and the softer hydrogel material.

    Abstract: The present application discloses that incorporation of dermatan sulfate and/or HA in composite scaffolds of certain polymers gives rise to a chondrogenic effect on chondrocytes resulting in formation of cartilage that resembles the natural ECM. This effect with dermatan sulfate as the primary additive has not previously been seen. The composites are formed by incorporation of dermatan sulfate finely dispersed particles optionally nanoparticles or as molecular dissolutions in a polymer matrix with no bonding between the DS and the matrix, providing the DS to the chondrocytes in an accessible non-crosslinked form.

  • Patent number: 9265611
    Abstract: A partial resurfacing implant for use in repairing an articular cartilage defect site that includes a top articulating portion having a top surface that is configured with at least one radius of curvature to approximate the surface contour of the articular cartilage surrounding the defect site. The implant also includes a supporting plate that has a top surface and a bottom surface. The top surface is attached to the top articulating portion by a locking mechanism. The bottom surface of the supporting plate is constructed to facilitate the insertion of the implant into the defect site. Extending from the bottom surface of the supporting plate is at least one implant fixation portion. The at least one implant fixation portion is integrally connected to and is oriented about normal relative to the bottom surface. A method of repairing an articular cartilage defect with the partial joint resurfacing implant is also disclosed.

  • Patent number: 9216085
    Abstract: A method of repairing an articular cartilage defect with the partial joint resurfacing implant includes surgically creating an opening in the articular cartilage defect site. The method also includes obtaining a partial resurfacing implant which is implanted into the opening. The partial resurfacing implant includes a top articulating portion, an implant fixation portion, and a locking mechanism. The implant fixation portion including an upper segment coupled to the top articulating portion and a bone interfacing segment configured to facilitate insertion into the articular cartilage defect site. The method further includes the bone interfacing segment being inserted into the opening with the top articulating portion and adjacent articular cartilage being positioned to each other to facilitate motion and load transfer over the defect site. Another method of repairing an articular cartilage defect with a partial joint resurfacing implant and a partial joint resurfacing implant are also disclosed.

  • Patent number: 9198763
    Abstract: A spacer for implantation into a subject is provided that includes a sterilized piece of cartilaginous allograft tissue. The piece forms a Y-shape with a base adapted to insert within a first carpo-metacarpal joint or carpo-metatarsal joint of the subject, and has a first area adapted to secure to a trapezium bone adjoining the joint, and a second arm adapted to secure to a proximal metacarpal or metatarsal bone adjoining the joint. A procedure for implanting the spacer includes exposing a target joint and abrading a bone surface interior to the joint to induce surface bleeding. The spacer base is then inserted into the joint. The spacer first arm is adhered to the first bone of the joint and the spacer second arm is adhered to the second bone of the joint. A kit is also provided for surgical implantation of the spacer.

  • Patent number: 9132015
    Abstract: Technologies related to tumid implants and pumps are generally described. In some examples, a tumid implant device may comprise an enclosed sack membrane adapted to fit between bones in a joint. Articulation of the joint may cause a first layer of the membrane to move through a first boundary section into a second layer of the membrane, while the second layer moves through a second boundary section into the first layer. A working fluid may be disposed inside the sack membrane, and a reservoir may optionally be coupled to the membrane via a gate. The working fluid may be expelled from the sack membrane into the reservoir, and may re-enter the sack membrane from the reservoir in response to changes in pressure in the joint. The working fluid may be conducted into the reservoir or sack membrane by a pump, and several artery pump designs are disclosed.

    Abstract: A surgical implant for replacing hyaline cartilage in a knee or other articulating synovial joint has an anchoring side on one side of the implant adapted for fixing the implant to one of the bones in the joint, and a bearing surface on the opposite side of the implant for lubricious rubbing and sliding contact with another bone in the joint. The anchoring side can be configured with an irregular surface for tissue ingrowth. The bearing side can include hydrogel. The implant can be rolled up from an original shape and surgically inserted by arthroscopic means, and opens into its original shape when released inside the joint.

  • Patent number: 9017417
    Abstract: This invention includes a subchondral bone repair system, comprising a structural component and a fluid settable component and an optional non-core component. The fluid settable component may penetrate into any pores of the structural component, and set to a solid, thereby fixing the structural component in place. The fluid settable component will penetrate interporously into the pores of the subchondral bone tissue surrounding the device, beneficially displacing any fluid to reduce edema in the affected bone region. Furthermore, the settable component, once solid is osteoconductive to promote repair and regrowth of bone in the affected region, and will also transmit mechanical force stimuli (such as compressive forces) directed through the structural component, into the adjacent bone tissue, thereby providing appropriate force stimuli necessary for appropriate tissue growth.
