  • Patent number: 10543096
    Abstract: A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores shock absorption, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device is pre-tensioned to improve the fit of the prosthetic device within the knee joint and, thereby, maximize the contact area of the load-bearing surfaces to distribute loading through the prosthetic device in a manner substantially similar to that of a healthy natural meniscus. In some embodiments, the pre-tensioned prosthetic device is smaller, or scaled-down, relative to the size of a healthy natural meniscus.

  • Patent number: 9034047
    Abstract: A prosthetic joint module to provide a variety of motions and functions similar to human joint systems during rigorous activities. The joint module includes a housing component attached to a proximal prosthetic device, an elastomeric polymer attached to the housing component and a yoke component attached to the elastomeric polymer and to a distal prosthetic device. The yoke component and distal prosthetic device are moved relative to the housing component and proximal prosthetic device causing the elastomeric polymer to distort. This distortion allows the joint module to flex, and absorb, capture, store and return the energy from the movement to of the yoke component.

  • Patent number: 9034049
    Abstract: Implantable assemblies/devices and methods are provided for manipulating energy transferred by members defining an articulating anatomical joint, wherein the members collectively define a path of motion. Assemblies/devices are provided with a first component configured to be attached to a first anatomical member of the anatomical joint, a second component configured to be attached to a second anatomical member of the anatomical joint; and a tension member joining the first and second components. The tension member is placed under tension to absorb energy transferred by the anatomical members when the first component is attached to the first anatomical member and the second component is attached to the second anatomical member and a distance between locations of attachment of the first and second components becomes smaller then an implant-defined distance between the locations.

  • Publication number: 20150127090
    Abstract: An implantable device includes at least one solid structure having an external surface and a volume beneath the surface. One or more of a first conductor or set of conductors is disposed externally and/or internally on or within the structure and an array of elongate electrically conductive elements are disposed radially outwardly within the volume. A breach is detected when a conductive fluid intrudes into the volume through the surface.

  • Publication number: 20150119993
    Abstract: The fusion device for fusing a synovial joint of a human or animal patient, in particular a human facet joint, finger joint or toe joint, includes two pin-shaped anchorage portions and arranged therebetween a stabilization portion. The anchorage portions include a thermoplastic material which is liquefiable by mechanical vibration. The stabilization portion preferably has a surface which is equipped for enhancing osseointegration. The anchorage portions have a greater thickness and a greater depth than the stabilization portion. Then the fusion device is pushed between the articular surfaces and mechanical vibration, in particular ultrasonic vibration, is applied to the proximal face of the fusion device. Thereby the liquefiable material is liquefied where in contact with the bone tissue and penetrates into the bone tissue, where after re-solidification it constitutes a positive fit connection between the fusion device and the bone tissue.

  • Patent number: 9017590
    Abstract: Solid-state deformation processing of crosslinked high molecular weight polymers such as UHMWPE, for example by extrusion below the melt transition, produces materials with a combination of high tensile strength and high oxidative stability. The materials are especially suitable for use as bearing components in artificial hip and other implants. Treated bulk materials are anisotropic, with enhanced strength oriented along the axial direction. The material is oxidatively stable even after four weeks of accelerated aging in a pressure vessel containing five atmospheres of oxygen (ASTM F2003). Because of its oxidative stability, the deformation processed material is a suitable candidate for air-permeable packaging and gas sterilization, which has thus far been reserved for remelted crosslinked UHMWPE.

  • Publication number: 20150112444
    Abstract: Sacroiliac (SI) joint implants for promoting SI joint fusion and methods of their delivery are described herein. The SI joint implant has a spacer operatively coupled to a planar member having tapered holes to receive fastening elements. When placed in the SI joint, the spacer engages the articular surfaces of the SI joint while the plate traverses the SI joint. The implant is held in place fastening elements, which are inserted through the tapered holes in the planar member. The implant is delivered via an inferior inlet MIS procedure, wherein the SI joint is accessed through an inlet inferior to the SI joint.
