Stent delivery device
First Claim
1. A handle apparatus for an endoluminal treatment device, comprising:
- a handle member;
a control member coupled to the handle member;
a shaft mounted to the handle member and coupled to the control member such that rotation of the shaft displaces the control member axially with respect to the handle member; and
a means for limiting rotation of the shaft to only one direction;
wherein the control member includes a groove along a proximal end portion of the control member, and the handle member includes a control member guide for slidably receiving the control member therethrough, the control member guide including at least one guide pin therein for engaging the groove along the proximal end portion of the control member to prevent rotation of the control member.

Abstract
A unidirectional handle device for an endoluminal device includes an outer tubular member and an elongate inner member slidably received in the outer tubular member. The unidirectional handle includes a handle member, a needle bearing clutch disposed in the handle member, a control member guide, and shaft rotatable in a single direction disposed within the handle member. The shaft is rotatable in a single direction by its engagement with the needle bearing clutch. The shaft is in rotational engagement with the outer tubular member of the endoluminal device. The outer tubular member is slidable from a distal position to a proximal position when the shaft is rotated in the single direction. The unidirectional handle device provides substantially no backlash of the outer tubular member. In addition, the unidirectional handle device advantageously produces a tension-retaining effect during use.

5. A system for delivering an endoluminal prosthesis within a body lumen of a patient, comprising:
-
a handle member; a control member slidably coupled to the handle member; an outer tubular member extending distally from the control member; an elongate inner member slidably disposed within the outer tubular member and axially fixed with respect to the handle member; a shaft rotatably mounted to the handle member, the shaft including a gear coupled to the control member such that rotation of the shaft displaces the outer tubular member axially with respect to the elongate inner member; and a means for limiting rotation of the shaft to only one direction, such that when the shaft is rotated in the one direction, the outer tubular member is directed from a distal position to a proximal position. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
