  • Publication number: 20160128823
    Abstract: Provided are porous, biocompatible implant bodies and materials. These materials suitably comprise a population of randomly arranged and entangled thermoplastic constituents, with at least some of the constituents being bonded to one another The implant bodies are capable of being manipulated at room temperature from a first shape to a second shape, and of maintaining the second shape at about internal body temperature. Also provided are related methods of fabricating such implants and installing the implants into a subject.

  • Publication number: 20150018969
    Abstract: A drug-impregnated sleeve for encasing a medical implant is provided. In one embodiment, the sleeve may include a body made of a biologically-compatible material that defines an internal cavity configured to receive the medical implant. In one embodiment, the biologically-compatible material is bioresorbable. The body may include a plurality of apertures, such as perforations or holes, extending from the cavity through the body. The sleeve may further include a first end, a second end, and a drug impregnated into the resorbable sheet. In one possible embodiment, the first end of the sleeve may be open for receiving the medical implant therethrough and the second end may be closed. The implant may be encased in the sleeve and implanted into a patient from which the drug is dispensed in vivo over time to tissue surrounding the implantation site. In one embodiment, the body is made from at least one sheet of a biologically-compatible material.

  • Publication number: 20140052060
    Abstract: The present invention provides a drug eluting surgical screw and a method for manufacturing a drug eluting surgical screw. The drug eluting surgical screw may include a shaft having a threaded portion, a head having a drive recess disposed at a proximal end of the shaft, the drive recess having a reservoir region and a driver engagement region, and at least one or more drug eluting components disposed within the reservoir region of the drive recess in a manner that does not substantially impair a connection between a driver and the surgical screw when the driver is operably disposed within the driver engagement region, each of the at least one or more drug eluting components including a carrier matrix and a therapeutic agent, the therapeutic agent being at least 20 wt % of the drug eluting component prior to any implantation of the drug eluting surgical screw.

  • Publication number: 20130218100
    Abstract: The present application discloses embodiments related to an implant and a method of forming an implant configured to treat a fractured bone. The implant can include a body having a proximal end, a distal end, and an outer surface extending from the proximal end to the distal end, wherein the body defines a central axis extending from the proximal end to the distal end; and a high tensile strand positioned adjacent the body such that at least a portion of the strand extends at least partially along the outer surface of the body in a direction substantially parallel with the central axis, and wherein the strand is loaded with an active agent.

  • Publication number: 20030001880
    Abstract: A method, system, and computer program product are provided to edit and encode enriched multimedia productions for live, delayed, or on-demand web casts or other distribution. The present invention is configured to operate independent of the system platform and media format. Hence, the present invention has the ability to operate with any type of manual or automated video production system. The multimedia production is produced according to an electronic show rundown. The rundown includes instructions for encoding the production for webcasting. In an embodiment, the multimedia is produced and broadcast over conventional channels simultaneously with a live or delayed web cast. The web cast material is edited, fragmented, tagged and/or archived during the simulcast. In another embodiment, the multimedia is produced and archived for on-demand web cast. Auxiliary information is added to enhance the multimedia production.
