Abstract: A tissue anchor insertion system for inserting a tissue anchor into a body tissue such as bone, comprising a cutting device having a sharp leading end to create an aperture in the bone for insertion of the tissue anchor therein. The cutting device is deployed through a sleeve which is a close fit with the cutting device. The distal end of the sleeve is typically configured to penetrate the tissue in which the tissue anchor is to be inserted. A tissue anchor is also deployed through the sleeve, after the sleeve is in position, on a delivery device configured to support the tissue anchor during its insertion into the tissue. Typically the leading end of the sleeve is embedded within the tissue when the tissue anchor emerges from the distal end during the insertion process, so the tissue anchor is not damaged by insertion through the tissue.

Abstract: Apparatus for handling of at least one implant for a body is provided. The apparatus has a radio translucent portion and a radio-opaque marking. The apparatus can optionally comprise a jig affixable to an intramedullary nail, which can be used to determine the position of holes to be drilled through a bone which align with holes in the nail. The radio-opaque marking will appear on an x-ray and can be used to indicate the relative alignment of the jig and the nail.

Abstract: An implantable replacement joint includes first and second components having respective bores, and a flexible member within a cavity formed by the respective bores.

Abstract: A method and apparatus for determining information concerning ischaemia using a pH sensor. Embodiments of the invention can be used to determine ischaemia caused by a number of factors, including acute compartment syndrome and vascular disorders, e.g. scepticaemia.

Abstract: The invention provides a tissue anchor comprising a first portion and a second portion. At least one point is provided on the first portion and a resilient device is provided between the first and second portions. The one or more points on the first portion can be sharpened and capable of penetrating dense tissue. The resilient device biases the first and second portions apart from one another in order to urge them into a second open configuration. The first and second portions are movable to a closed delivery configuration. The first and second portions are urged towards one another against the bias of the resilient device in the closed delivery configuration.
