Abstract
A handle assembly for use in the deployment of a medical device via a plurality of deployment lines that extend through a catheter. The handle assembly includes a plurality of removable members for deployment or actuation of the medical device. The handle assembly also includes an actuating mechanism for displacing a wire extending through the catheter for actuating the medical device independently of the plurality of removable members.
Claims11
A handle assembly for use in the deployment of a medical device via a plurality of deployment lines that extend through a catheter, said handle assembly comprising:
- a plurality of removable members each being attached to at least one of the plurality of lines, wherein each of the plurality of lines is operatively coupled with the medical device for selective deployment or actuation thereof, the plurality of removable members being removably attached to each other such that only one of the removable members is presented for manipulation by a user and removal of each of the removable members presents another of the removable members for manipulation by the user;
- and
- an actuating mechanism for displacing a wire extending through the catheter for actuating the medical device independently of the plurality of removable members.
A handle assembly for use in the deployment of a medical device via a plurality of deployment lines that extend through a catheter, said handle assembly comprising:
- an actuating mechanism for displacing a wire extending through the catheter for manipulating the medical device independently of the plurality of deployment lines, the actuating mechanism having:
- a threaded rod extending along a longitudinal axis;
- a nut threadingly engaged to the rod and coupled to an end of the wire such that the nut and wire translate generally along the longitudinal axis in response to selective rotation of the rod about the longitudinal axis;
- and
- a tube extending through and being rotatably coupled to the rod for rotation of the rod about the longitudinal axis,
- wherein the tube further includes a bore generally continuous with at least one lumen in the catheter to allow routing of a guide wire through the catheter and through the handle assembly.

- an actuating mechanism for displacing a wire extending through the catheter for manipulating the medical device independently of the plurality of deployment lines, the actuating mechanism having
- a threaded rod extending along a longitudinal axis;
- a nut threadingly engaged to the rod and coupled to an end of the wire such that the nut and wire translate generally along the longitudinal axis in response to selective rotation of the rod about the longitudinal axis;
- and
- a tube having an outer bearing surface for rotatably supporting the threaded rod for rotation about the longitudinal axis and an opposite inner surface defining a bore that is generally continuous with a lumen in the catheter to allow a guide wire to pass through the catheter and the handle assembly for access of the guide wire outside of the handle assembly.
