Abstract: A golf club or implement comprising a grip region (14), a head (15), and a shaft (12) connecting the grip region (14) to the head (16). A fairing (20) is attachable to a trailing edge of the shaft (12). The fairing can reduce drag associated with the shaft (12) during a swing motion of the club or implement. The fairing can, on attachment, extend along a portion of the shaft (12) from a location proximal the head (16) of the club or implement.

Abstract: A process of forming a prosthetic implant component, such as the femoral component of a knee replacement prosthesis. The process comprises the steps of: (i) forming a prosthetic component having a shape at least approximating the desired final shape of the component from a metal alloy; (ii) subjecting the component to a relatively elevated temperature and pressure followed by a cooling regime; (iii) machining the surface of the component; (iv) polishing the surface of the component.

Abstract: A reinforcement device (10) suitable for use with a prosthesis, such as a unicompartmental tibial component prosthesis. The reinforcement device is positionable between said component prosthesis and a surgically resected area of bone, for example, the tibia of a patient. The reinforcement device (10) includes a plate-like main body (12) extending from an anterior end (13) to a posterior end (14) and having an upper surface (16) and a lower surface (17). The lower surface (17) is engageable with a fixing means, such as a bone cement (25), to fix the tibial component to a surgically resected area of tibia. The main body (12) also has a plurality of perforations (15) therethrough.

Abstract: A valve assembly (10) has a support ring (20) and a valve body (30). The valve body (30) is supported by the ring (20) and comprises an annular body portion (31) that is rotatably engageable with the support ring (20). The annular body portion (30) supports a plurality of leaflets (32) that are moveable relative to each other and the annular body portion (30) between: a closed position and an open position upon changes in pressure differential across the valve assembly (10).
