Abstract: An implantable prosthetic patellar component comprises a patellar part (1) having one side (1a) adapted to be secured to the inner surface of a natural patella (10), and a femoral part (3) having one side (5) defining an articulation surface to replace the femoral facet of the patella, the opposite surfaces (1b and 3a) of said parts being mutually engageable to afford sliding movement therebetween in a medio-lateral direction.The implant is able to accommodate relative medio-lateral movement and thereby improve congruency. It may be used in combination with other prosthetic components in a knee joint.

Abstract: A device to facilitate self-catheterisation in women suffering from deviation from normal bladder function is provided. The device includes a handle designed for manipulation by a patient and a catheter co-operable with the handle such that the catheter can be inserted into the patient's urethra by manipulation of the handle. The device has a flexion portion to allow the catheter to be positioned in a desired orientation relative to the handle for ease of insertion. The handle and catheter may be designed as a one-piece disposable construction or may be separate elements, the handle being useable with disposable catheters. The flexion portion may be an articulation structure, such as a ball-and-socket joint. Catheterisation is further facilitated by the provision of a mirror and/or light source on or associated with the handle.
