Abstract: An arthroscopic drill for insertion into a human joint of a human body comprising an elongate body extending between a proximal end which, during use, remains external to the human body and a distal end which, when in an operative configuration, is positioned in the human joint adjacent to a target structure within the human body (e.g. preferably a joint surface); a drill bit having a proximal portion adjacent the distal end of the elongated body, the drill bit having a distal portion extending to the target structure; and an introducer sheath having a lumen with an inner diameter of at least 2 mm and a bending stiffness of approximately 0.08 Nm2, wherein the operative configuration, the elongate body extends through the introducer sheath.

Abstract: Disclosed is a patellar cutting jig for use in a knee joint surgical procedure. The jig grips and holds a patella in situ in spatial reference to the femur to enable the appropriate cut to be made to the patella to accurately accommodate the patello-femoral gap at the replacement knee joint. The patella jig has a referencing component that provides a landmark connection between the patella jig and the femur which enables the patella clamp of the jig to be oriented relative to the reference feature prior to gripping the patella. Thus a patella held in the clamp is fixed in the cutting jig an appropriate orientation relative to the femur prior to its resection. Cutting the patella while it is referenced to the patellar groove on the femur increases the accuracy of the resection.

Abstract: An acetabular reamer (10, 10?, 10?) is intended in particular for the shaping of the cotyloid cavity in the event of a replacement of a hip joint by total prosthesis. The reamer (10, 10?, 10?) is typically of a truncated hemispherical form and is adapted for attachment to a reamer spindle in order to be driven in rotation about a cutter axis (11). The ability to cut a full, continuous hemisphere to the apex (12) of the hemispherical body (14) is suppressed, so as to attain the principal advantage of the invention, namely, to adequately prepare the acetabulum for receipt of a prosthesis while minimizing the possibility of breakthrough of the fovea/acetabular fossa. The reamer (10, 10?, 10?) has an interface 16 typically made tip of cross bars (20) which a holder engages for rotationally activating the reamer for cutting.

Abstract: The present invention provides implantable receptacle devices (and methods) for use in bone and tissue regeneration which provide immediate structural stability and strength to a zone where tissue regeneration is required. By virtue of their size, shape and construction, the devices are scalable, modular, structurally stable, self-stacking in three dimensions, can be aggregated to an anatomically accurate shape, and hold various materials delivered into the implant area so as to create a highly regenerative micro-environment. They can be implanted via less invasive surgical procedures, and because they act as external scaffolding as well as being imbedded as an integral part of a matrix for the effective and rapid regeneration of bone and cartilage in vivo, they may provide significant advantages to patients or subjects in terms of reduced pain, faster healing and fewer complications.

Abstract: Bone replacement tissue suitable for bone grafting procedures, said bone replacement tissue being grown in a host until suitable for translocation into a desired position in a patient, and methods for manufacturing said bone replacement tissue.
