APPARATUS FOR IMPLANTING A DEVICE
First Claim
1. Apparatus (10) suitable for placement of a tubular prosthetic device within a natural body lumen, wherein said apparatus comprises a flexible elongate member (30) for positioning of the tubular device, a sheath (36) for holding the tubular prosthetic device in a first configuration upon the flexible member, a handle for manipulating the flexible elongate member, said handle comprising first and second control means (120, 122) operable independently to effect movement of the sheath with respect to the flexible member by use of respective first and second sheath sliders (20, 24) wherein the first control means (120) is configured for effecting a rotation about an axis, and the second control means (122) is configured for translation along an axis, wherein the first control means is operably connected by means of a draw wire (121) to the first sheath slider (20) which in a first position is contiguous with the second sheath slider (24), and said second sheath slider is selectively separable from said first sheath slider by means of the second control means (122), and said first and second sheath sliders are slidable along a common axis, the second sheath slider being operably connected to the sheath for displacement thereof relative to the flexible elongate member.

Abstract
The apparatus has a delivery shaft 30 bearing a tubular device constrained within a moveable sheath 36, and a handle comprising a hollow shaft 124 with a static grip 126 and a grip slider 122 movable proximally or distally. The grip slider is connected to a slider block 24 fixed to a sheath hub 6 to which the sheath is fastened. A retraction wheel 120 has a spool 2 for winding a retraction wire 121 connected to a retraction block 20 in 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.
