Abstract
Mechanisms for pulling a tensile member a predetermined distance from a medical device having an intracorporeal end and an extracorporeal end are disclosed. Such mechanisms may be safely operated using a robot, two hands, or in some embodiments, only one hand. Such mechanisms may include one or more cams, drums, or pulley-like members and a lever, and may be physically coupled to an extracorporeal portion of the medical device.
Claims73
An elongated vascular implant delivery device comprising:
- an elongated shaft having a distal end, a proximal end, and a longitudinal axis;
- a release mechanism;
- a lever rotatably coupled to the elongated shaft;
- a tensile member coupled to the release mechanism at a first point along its length and coupled to the lever at a second point along its length and a length of tensile member between the first and second points disposed within or alongside the elongated shaft;
- a cam for a length of the tensile member between the first point and the second point, the cam coupled to the elongated shaft,
- wherein the lever, cam, and tensile member are adapted to cooperate such that rotation of the lever through a prescribed angle with respect to the elongated shaft will move the release mechanism toward the proximal end of the elongated shaft.

An elongated vascular implant delivery device comprising:
- an elongated shaft having a distal end, a proximal end, and a longitudinal axis;
- a release mechanism;
- a tensile member coupled to the release mechanism at a first point along its length and coupled to an extracorporeal member at a second point along its length;
- and
- a mechanical means operable with one hand for pulling the tensile member with respect to the elongated shaft;
- wherein the mechanical means includes the extracorporeal member and if the mechanical means operates to pull the tensile member with respect to the elongated shaft, the release mechanism moves toward the proximal end of the elongated shaft.
