Abstract:
A prosthetic elbow for replacing an elbow of a dog or a human to restore normal, pain-free joint function. The elbow includes a humeral component for attachment to a humerus and a radioulnar component for attachment to an ulna. The humeral component includes a generally cylindric spool having a contoured external surface defining a first articular surface. The radioulnar component has a generally U-shaped contour with an inner peripheral surface defining a second articular surface sized and shaped for engagement with the first articular surface. Positional guides provide for implantation at precise locations.
Abstract:
A suture needle construct and method for extracapsular ligament reconstruction in mammals. The joint is first is first explored, and the damaged ligament and meniscus are debrided. The joint capsule is closed and a tunnel is created at the appropriate location in the proximal tibia for tibial fixation. Subsequent to the formation of the tibial tunnel, a suture having a substantially curved needle at one end and a substantially straight needle at the other end is brought in the proximity of the joint. The suture is passed around the lateral fabella using the substantially curved needle, then deep to the patellar ligament using the substantially straight needle, and through the tibial tunnel using the straight needle. The needles are cut off, and the sutures are tensioned over repair site.
Abstract:
An apparatus and method for stabilization of a cranial cruciate ligament deficient stifle in canines using a suture-button construct. The method includes the steps of drilling a femoral hole across a distal femur, passing a needle with a pull-through suture strand of a suture-button construct through the femoral hole, and applying a tensile force to the pull-through suture strand and a suture tape or strand of the construct such that a first button of the suture-button construct lies sideways for passage through the femoral hole, advancing the first button through the femoral hole by pulling the pull-through suture strand until the first button exits the femoral hole, drilling a tibial hole and passing the needle with the pull-through suture strand through the tibial hole, applying a tensile force to the pull-through suture strand and the suture tape or strand of the construct such that the first button lies sideways for passage through the tibial hole, flipping the first button to engage the first button against the medial tibial cortex and subsequently cutting and removing the pull-through suture strand, pulling free ends of the suture tape or strand to advance a second button of the suture-button construct and to seat the second button against the femur, and securing the second button against the femur.
Abstract:
The apparatus is comprised of a platform from which a player may drive a ball into an enclosure. A sloping floor is provided to return balls to a reservoir placed under the platform. A teeing mechanism operated by a player presents balls one at a time to a tee. The mechanism is comprised of a pneumatic system with master and servo bellows.
Abstract:
An adjustable, knotless button/loop/needle construct for fixation of cranial cruciate ligament deficient stifle. The adjustable, knotless construct includes two fixation devices (for example, two buttons), at least one flexible, adjustable loop attached to at least one of the fixation devices (e.g., the buttons), and two needles (each needle being attached to one fixation device, e.g., the buttons). The adjustable, knotless construct has an adjustable loop length and allows adjustment in one direction while preventing or locking the construct from loosening in the opposite direction, due to applied tensile forces. The construct and technique of the present invention provides an improved knotless system for cruciate ligament repair.
Abstract:
Implants for resurfacing or repairing one or more articular cartilage bearing surfaces of a biological organism include an engineered tissue and a biocompatible porous substrate secured to the engineered tissue for attaching the implant to a native bone of the biological organism. The engineered tissue includes a scaffold containing a biocompatible material, and a plurality of living chondrocytes supported by the scaffold. Methods for culturing chondrocytes for incorporation into a biocompatible implant are provided. A bioreactor for producing functional cartilaginous tissue from a cell-seeded scaffold and a system for producing functional cartilaginous tissue are also provided.
Abstract:
Methods and instrumentation for arthroscopic elbow surgery which include a humeral component. The humeral component is installed in a trough formed in the humeral condyle. The trough may be formed by using a plurality of drill pins and a plurality of corresponding cutters (and optionally a template). The two drill pins are passed through the template and drilled into the humerus, and cutters are advanced over the corresponding drill pins to form the trough. The humeral component may be employed in conjunction with an ulnar implant.

Abstract:
An elbow arthroplasty system having a ball and a socket. The ball is configured for coupling to at least one member of one of the following groups: (i) a humerus, and (ii) a radius, an ulna, or both of the radius and the ulna. The socket is configured for coupling to at least one member of the other of the following groups: (i) the humerus, and (ii) the radius, the ulna, or both of the radius and the ulna. The socket defines a cavity that is configured to receive at least a portion of the ball. The ball may be a spheroid, an ellipsoid, a sphere, or a portion of one of the foregoing with a convex surface. The socket may be configured with a concave surface that is spheroidal, ellipsoidal, or spherical and designed to mate with the ball. An elbow arthroplasty method using a ball and a socket.
Abstract:
Systems, apparatus, and methods may be adapted for grafting tissue at a tissue site that may include an elongate housing and a plurality of elongate cutting members. The plurality of elongate cutting members may define a cutting surface at a distal end of the elongate housing. The cutting surface may be adapted to contract from a first diameter to a second diameter that is less than the first diameter. The contraction of the cutting surface from the first diameter to the second diameter may define a tapered profile between the first diameter and the second diameter suitable for obtaining a tapered graft.
