Abstract: An additively manufactured medical implant, comprising a metallic body having at least one porous surface configured to promote bony on-growth or in-growth of tissue, the porous surface being replicated from a high resolution scan of bone, and a biological surface coating configured to create a barrier to particulate debris, the biological surface coating being produced from a titanium porous plasma spray surface coating or a biomimetic coating.

Abstract: This application describes an implantable device for tissue repair comprising at least two fabrics with interconnecting spacer elements transversing, connecting, and separating the fabrics, forming the device. Some embodiments have fixation points which can be an extension of at least one of the fabrics. The implantable device allows modification of the two fabrics having varying constructions, chemistries, and physical properties. The spacer elements create a space between the two fabrics, which can be used for the loading of biological materials (peptides, proteins, cells, tissues), offer compression resistance (i.e. stiffness), and compression recovery (i.e., return to original dimensions) following deformation and removal of deforming load. The inclusive fixation points of the fabrics are designed to allow for fine adjustment of the sizing and tension of the device to promote integration with the surrounding tissues as well as maximize the compressive resistance.

Abstract: A bone fusion device provides stability to bones during a bone fusion period. The bones include, for example, the vertebrae of a spinal column. The bone fusion device comprises one or more extendable tabs attached to the bone fusion device by associated rotating means. The bone fusion device is preferably inserted by using an arthroscopic surgical procedure. During arthroscopic insertion of the device, the tabs are pre-configured for compactness. In this compact configuration, the tabs are preferably deposed along and/or within an exterior surface of the bone fusion device. After the bone fusion device has been positioned between the bones, one or more tab(s) are extended. In the preferred embodiment, the position of each tab is related to a positioning element and extending blocks. Typically, the tabs advantageously position and brace the bone fusion device in the confined space between the bones until the bones have fused.

Abstract: Provided is a system and method for providing a non-binding allograft subtalar joint implant for surgical implant into a person's foot proximate to the ankle. This system for repair includes at least one sterile non-binding allograft subtablar joint implant provided as a pre-formed allograft rod plug “ARP” having a diameter about equal to an average width of a canal between a person's talus and calcaneus bones, the ARP being resiliently compressible and flexible. When snuggly disposed between the person's talus and calcaneus bones, the ARP compresses during normal use of the person's foot and maintains the canal in an anatomically correct alignment and reduces a tendency for abnormal motion between the person's talus and calcaneus bones. An associated method of use is also provided.

Abstract: Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve. An annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation. A protective device can be placed between the annuloplasty device and an underlying coronary artery to inhibit compression of the underlying coronary artery by the annuloplasty device in the coronary sinus. In addition, the protective device can inhibit compression of the coronary artery from inside the heart, such as from a prosthetic mitral valve that exerts radially outward pressure toward the coronary artery. The annuloplasty device can also create an artificial inner ridge or retaining feature projecting into the native mitral valve region to help secure a prosthetic mitral valve.

The blade component includes a buttress portion and a neck portion, with the neck portion having a body segment and a face segment that is contoured for mating engagement with an outer surface of the acetabular shell. The augment component has a first opening sized and shaped to receive insertion of the body segment, and which is also sized to accommodate selective adjustment of, when the body segment is positioned in the first opening, linear and angular orientations of the blade component relative to the augment component. Additionally, the body segment has a length that is sized to facilitate direct contact of the face segment with the acetabular shell when the variable angle blade augment is in an assembled configuration. Further, cement can be injected into the internal cavity to unitize the connection between the acetabular shell and the blade component.

Abstract: A connector for attaching a connective tissue to bone includes a sling for supporting and holding the connective tissue. A trap generally cooperates with the sling. The trap includes an anchor end and a sling end and a generally tubular section configured to decrease in diameter upon application of a longitudinal tensile force. The trap is dimensioned to fit within a tunnel through bone so that the connective tissue emerges from one end of the tunnel and so that an interference screw can be inserted into the tubular section at the anchor end of the trap at the other end of the tunnel whereby a pulling force exerted on the sling causes the generally tubular section of the trap to constrict more tightly about the interference screw to prevent slippage and to deter withdrawal of the trap from the tunnel.
