  • Patent number: 8728168
    Abstract: A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of a cavity of a bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the support structure by an adhesive. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining the channel between the pair of components.

  • Publication number: 20130304221
    Abstract: A tibial augment for use with a knee joint prosthesis, composed of annular members of different stock sizes, each size being configured to fit within a cavity formed in a human tibia. The augment may include a stepped distal surface. A provisional (temporary) tibial augment used to ensure a proper fit for the permanent augment is also provided. The provisional may include grooves configured to cooperate with a set of ribs on a tong-like holder used for removing the provisional from the cavity. A pusher for use implanting the tibial augment is also provided. In addition, a system for creating a cavity in a human tibia is also described. The system preferably includes a guide with a slot therein and a set of osteotomes that are inserted within different portions of the slot. Methods for using the tools and/or implanting the prosthetic devices discussed above are also described.

  • Patent number: 8535385
    Abstract: A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of the cavity in the end of the bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the channel by an adhesive. The stem of the prosthesis beyond the channel may be cemented or uncemented. The support structure may have an approximately funnel shape. The support structure may be a hollow porous cylindrical sleeve. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining a channel between the pair of components. The support structure may comprise a plurality of pedestals secured to the inner surface of the cavity of the bone.

  • Patent number: 8076117
    Abstract: Methods, kits, and systems for removing microbial biofilms from surfaces of objects (such as, e.g., explanted medical devices) are disclosed. The methods, kits, and systems rely on the use of acoustic energy in the presence of microbubbles to enhance biofilm removal while retaining viability of the microorganisms in the biofilm. The microbubbles may be provided in a variety of manners such as, e.g., vortexing a liquid, obtaining a suspension that includes pre-formed protein-stabilized microbubbles, etc.

  • Publication number: 20110112651
    Abstract: A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis. The present invention is intended for situations in which the distal portion of the femur is defective, and it provides a method and devices that allow for preservation of healthy peripheral bone, while still providing the necessary augmentation to the distal portion of the femur.

  • Patent number: 6709462
    Abstract: An outer shell for a socket of a joint prosthesis is disclosed. The outer shell includes an outer wall defining an outer surface of the shell and an inner wall defining an inner surface of the shell. The outer wall has pores to permit bone tissue to grow into the outer wall, and the inner surface of the shell engages the socket. The inner wall has access channels suitable for seating a bone screw. The access channels are closed off by an associated integral section of the shell. Preferably, each access channel is closed off by a section of the outer wall so that the shell retains maximal outer surface area for bone tissue ingrowth. When a number of bone screws are needed for affixation of the shell to bone, a number of locations for bone screws can be created in the shell by opening the closed access channels.
