A handle for a medical device is provided. The handle includes an inner handle member and first and second outer handle members slideably disposed on the inner handle member. An elongate sheath is attached to the inner handle member and extends axially beyond a distal end of the inner handle member and a stylet is attached to one of the outer handle members and disposed in a lumen of the sheath. Slideable movement of the outer handle members relative to the inner handle members controls relative positioning of various components of the handle.

A handle according to claim 5, wherein the means for fixing comprises an engaging member extending through a thickness of the second outer handle member.7. A handle according to claim 6, wherein the engaging member comprises a thumbscrew.8. A handle according to claim 1, wherein the stop is affixed to the inner handle member and is configured to prevent axial movement of the first outer handle member into the distal end portion of the inner handle member, and prevent axial movement of the second outer handle member into the proximal end portion of the inner handle member.9. A handle according to claim 8, wherein the stop comprises a projection defined by the inner handle member.10. A handle according to claim 9, wherein the stop comprises a circumferential projection.11. A handle according to claim 1, further comprising a first series of gradations disposed on the inner handle member.12. A handle according to claim 11, wherein each gradation of the first series of gradations corresponds to a predetermined length by which the stylet extends axially beyond a distal end of the sheath.13. A handle according to claim 11, further comprising a second series of gradations disposed on the inner handle member.14. A handle according to claim 13, wherein each gradation of the first series of gradations corresponds to a predetermined first length by which the stylet extends axially beyond a distal end of the sheath, and each gradation of the second series of gradations corresponds to a predetermined second length by which the sheath extends axially beyond a distal end of the second outer handle member.15. A handle according to claim 1, further comprising a slideable member disposed on the inner handle member and adapted to be locked on the inner handle member.16. A handle according to claim 15, wherein the slideable member is disposed between the first and second outer handle members.17. A handle according to claim 15, wherein the slideable member comprises a mechanical stop that limits axial movement of the first outer handle member along the inner handle member.18. A handle according to claim 15, further comprising a series of gradations disposed on the inner handle member, wherein the slideable member defines an aperture disposed over a portion of the series of gradations.19.
