  • Patent number: 8940046
    Abstract: The present invention relates to a method of implanting a prosthesis device in a subject. In one embodiment, this method involves: (i) providing a prosthesis device to be attached to an exposed surface of a bone; (ii) applying bone cement in liquid form to a bone-implant interface region, the bone-implant interface region including a region between the exposed surface of the bone and an outer surface of the prosthesis device; and (iii) contacting the bone cement to the exposed surface of the bone and the outer surface of the prosthesis device under conditions effective to allow the bone cement to cure, thereby resulting in attachment of the prosthesis device to the bone of the subject. The present invention also relates to a kit for implanting a prosthesis device in a subject, a method of performing a joint arthroplasty surgical procedure, and other methods of using bone cement in liquid form.

  • Publication number: 20140074104
    Abstract: An injector assembly for delivering flowable material to a medical implant, including a tube having a first end and a second end, a connector member and a port connector, where the connector member is coupled to the first end of the tube and the port connector is coupled to the second end of the tube, the connector member being configured to attach to a material delivery mechanism and the port connector being configured to attach to the medical implant. When the material delivery mechanism is actuated, the flowable material passes through the tube to the medical implant. A method of using an injector assembly to deliver a flowable material to a medical implant and bone surface is also described. A kit containing various sized parts for an injector assembly is also described.

  • Patent number: 8608747
    Abstract: The invention provides a guide for controlling a surgical instrument, that includes a cutting member configured to resect a portion of anatomy and a sheath. The sheath may have a circular connecting portion with an inner diameter substantially the same as the outer diameter of the surgical instrument to receive the surgical instrument. The sheath may also include at least two distally extending arms connected to the circular connecting portion and a ring connected to the distal portion of the at least two distally extending arms. The sheath may also include a distally extending extension connected to the ring. The guide has a superiorly extending guard connected to the distal portion of the extension and a projection member positioned on a superior surface of the guard. The projection member includes a generally circular base and circular platform that has a diameter larger than the generally circular base.

  • Patent number: 8226727
    Abstract: The present invention relates to a femoral prosthesis that includes a cement introduction port which may be used to facilitate delivery or introduction of bone cement into the prosthesis/bone interface after the prosthesis component has been placed on a resurfaced femur bone. The femoral prosthesis may have a keel with undercuts which are configured to assist in controlling the flow of bone cement during implantation and to improve stability of the prosthesis following implantation. The femoral prosthesis is suitable for implantation using arthroscopic, as well as open, surgical procedures. The present prostheses may be used as unicondylar implants in either compartment of the knee or in both compartments of the knee.

  • Publication number: 20110276051
    Abstract: A resection tether that includes an elongated member having a medial end and a lateral end. The lateral end is configured for attachment to a cutting device and the medial end is configured for attachment to a reference locator positioned in a bone. When attached at both ends, the resection tether controls the movement of the cutting device relative to the reference locator. Further disclosed is an apparatus that includes a tether having an elongated member that includes a medial end and a lateral end. The lateral end is configured for attachment to a bone cutting device and the medial end configured to attach a position on a bone. The apparatus includes a bone cutting device and a reference locator that has been positioned within a bone. Also disclosed are methods for using a tether to perform a bone resection and for creating an inlay bone resection.

  • Publication number: 20110270327
    Abstract: An implant guide for preparing a bone surface that includes a handle with an attached finger holder and a template head coupled to the handle. The template head is shaped to approximate the outer perimeter of an implant. The implant guide also includes a central opening that has an aperture and hook for receiving a marking device. A relief is positioned adjacent to the aperture to facilitate the engagement between the implant guide and the marking device. The implant guide may include a medial cutting notch and anterior slot for facilitating the preparation of the bone surface. A surgical kit is also disclosed that includes a plurality of implant guides, each having a handle and attached template head. The kit also includes an enclosure that is configured to hold the plurality of implant guides and marking devices. Further disclosed is a surgical method for using the implant guide.
