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.
