The apparatus has a delivery shaftbearing a tubular device constrained within a moveable sheath, and a handle comprising a hollow shaftwith a static gripand a grip slidermovable proximally or distally. The grip slider is connected to a slider blockfixed to a sheath hubto which the sheath is fastened. A retraction wheelhas a spoolfor winding a retraction wireconnected to a retraction blockin contact with the slider block enabling the slider block to be pushed as the retraction block is retracted distally. Initial incremental movement of the retraction block by winding of the retraction wire, moves the slider block and retraction block simultaneously. Subsequently the slider block is movable independently of the retraction block using the grip slider, leaving the retraction block behind.

Apparatus for implanting a device

There is provided a device to secure a prosthesis, such as a stent graft, to the internal wall of a body lumen. The device is formed from two elongate elements each comprising a central portion with at least one arm extending therefrom. The central portions of the elements abut. Optionally, the central portions are joined together, optionally by a joining element which can act as a hinge. The terminal end of each arm can be shaped for engagement with the inner surface of the body lumen. The device is reversibly interchangeable between a first folded configuration and a second deployed or open configuration. The device is preferably attached to the sleeve of a stent graft independent of the stents which are preferably ring stents. A stent graft comprising the device is also described.
