Bone graft containment system
The present invention relates to methods for bioresorbable and biodegradable casings having both micropores and macropores for providing shape, structure and containment to different bone grafting materials. Kits and methods of use are also described.
Implantable medical device with varied composition and porosity, and method for forming same
A method for forming a thermoplastic body having regions with varied material composition and/or porosity. Powder blends comprising a thermoplastic polymer, a sacrificial porogen and an inorganic reinforcement or filler are molded to form complementary parts with closely toleranced mating surfaces. The parts are formed discretely, assembled and compression molded to provide a unitary article that is free from discernible boundaries between the assembled parts. Each part in the assembly has differences in composition and/or porosity, and the assembly has accurate physical features throughout the sections of the formed article, without distortion and nonuniformities caused by variable compaction and densification rates in methods that involve compression molding powder blends in a single step.
Medical implants
The current invention is directed to a medical implant made of bulk-solidifying amorphous alloys and methods of making such medical implants, wherein the medical implants are biologically, mechanically, and morphologically compatible with the surrounding implanted region of the body.
Device to be implanted in human or animal tissue and method for implanting and assembling the device
An implant or endoprosthesis suitable to be implanted in human or animal tissue includes two (or more than two) parts to be joined in situ. Each one of the parts includes a joining location, the two joining locations facing each other when the device parts are positioned for being joined together, wherein one of the joining locations includes a material which is liquefiable by mechanical vibration and the other one of the joining locations includes a material which is not liquefiable by mechanical vibration and a structure (e.g. undercut cavities or protrusions) suitable for forming a positive fit connection with the liquefiable material. The joining process is effected by pressing the two device parts against each other and by applying ultrasonic vibration to one of the device parts when the two parts are positioned relative to each other such that the two joining locations are in contact with each other.
SYSTEMS AND METHODS FOR MANUFACTURING ORTHOPEDIC PROSTHESES
An orthopedic prosthesis mold, comprising a first housing including a first cavity therein shaped to form a portion of an orthopedic prosthesis; a second housing coupled to the first housing, the second housing including a second cavity therein shaped to form a portion of an orthopedic prosthesis, wherein the first and second housings are constructed from a material having a first hardness; a first shell element configured to receive at least a portion of the first housing therein; a second shell element configured to receive at least a portion of the first housing therein, wherein the first and second shell elements are constructed from a material having a second hardness greater than the first hardness; and a connection element releasably engageable to the first and second shell elements to prevent separation of the first shell element from the second shell element.
Method of designing orthopedic implants using in vivo data
The present disclosure is directed to orthopedic implants and methods of rapid manufacturing orthopedic implants using in vivo data specific to an orthopedic implant or orthopedic trial. Specifically, the instant disclosure utilizes permanent orthopedic implants and orthopedic trials (collectively, “implants”) outfitted with kinematic sensors to provide feedback regarding the kinematics of the trial or implant to discern which implant is preferable, and thereafter rapid manufacturing the implant.
Implant pellets and methods for performing bone augmentation and preservation
Embodiments described herein are related to pellets that are placed within an extraction site that is in need of bone augmentation and preservation. The pellets are typically cylindrical in shape and comprise a material and a polymer coating. The goal of the pellets are to encourage sufficient new bone growth that jaw bone deterioration is prevented. The pellets create, arrange, and assemble an ideal growth environment for new bone growth to rapidly grow and preserve the original contours of an individual's jaw bone.
Mobile prosthesis for interpositional location between bone joint articular surfaces and method of use
A biocompatible prosthetic device comprising a thin low friction spacer for location to overlie a bone member in an interpositional location between opposed bone joint articular surfaces. The prosthesis is preferably a thin spacer with at least one low friction surface, the spacer being adapted for location about a bone member in an interpositional location between opposed bone joint articular surfaces preferably about a margin of articular cartilage of a bone member's condyle, preferably without any modification of the articular surface of the condyle. One preferred use of a prosthesis is in a human temporomandibular joint as a thin cap-like member fitted closely over the mandibular condyle to be disposed intermediate of the mandibular condyle and the mandibular fossa of the temporomandibular joint.
PROSTHETIC IMPLANT FOR BALL AND SOCKET JOINTS AND METHOD OF USE
A hip prosthesis includes an acetabular cup and a femoral component comprising a head and a stem, wherein the stem comprises a truss structure, the truss structure comprising a space truss comprising a plurality of planar truss units having a plurality of struts joined at nodes, wherein the web structure is configured to interface with bone tissue.
Assembled implant
This invention is directed to an assembled implant comprising two or more portions of bone that are held together in appropriate juxtaposition with one or more biocompatible pins to form a graft unit. Preferably, the pins are cortical bone pins. Typically, the cortical pins are press-fitted into appropriately sized holes in the bone portions to achieve an interference fit. The bone portions are allograft or xenograft.
