The present invention relates to an apparatus for affixing intramedullary devices in a body. In particular the apparatus comprises a jig affixable to an intramedullary nail. There is also provided a method of determining the position of holes to be drilled through a bone which align with holes in the nail.

Variable curve jig for an intramedullary device

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.

A surgical guide device comprises first and second limbs pivotally connected together, with a respective guide sleeve pivotally attached to each limb. Each guide sleeve has a bore through the sleeve that can guide a drill bit or bone fixing for insertion into a fragmented bone portion. The device has an orientation mechanism adapted to change the orientation of the guide sleeves relative to the limbs as the limbs move relative to one another, so as to maintain the orientation of the guide sleeves relative to one another during pivotal movement of the limbs.

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.

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

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.

Method and apparatus for determining ischaemia

A bone fixture apparatus has an elongate fixture device intended to be inserted in a metaphysical region of a long bone. The device is inserted generally transversely of the direction of the medullary cavity in the bone. The fixture device includes an aperture extending laterally thereof and intended to accommodate an intramedullary nail inserted longitudinally therethrough into the cavity. The fixture device is further formed with an axial aperture intended to receive a securing element capable of insertion therein to firmly engage said nail with the fixture device. Also disclosed is a jig arrangement for locating, relative to a long bone, the bone fixture apparatus.
