Control System for a Stent Delivery System
First Claim
1. A control system for controlling movement of a medical device delivery system having a first shaft and a second shaft, the first shaft movable relative to the second shaft, the control system comprising:
- a first arm comprising a first end portion, the first arm movable between a first position and a second position;
the first arm operably connected to one of the first shaft and the second shaft;
a second arm comprising a second end portion, the second arm operably connectable to the other of the first shaft and the second shaft;
a first actuator operably connected to the first arm;
the first actuator operable to move the first arm from the first position to the second position; and
a biasing member for biasing the first actuator;
wherein movement of the first arm moves the first shaft relative to the second shaft to change the position of the second shaft relative to the first shaft.

Abstract
A control system for controlling movement of a medical device delivery system, a stent delivery system and a method for controlling movement of a medical device delivery system are provided. The control system includes a first extendable arm comprising a plurality of first struts interconnected at intermediate points and end points of the first struts. The first arm is movable between a first position and a second position and the first arm is operably connected to one of the first shaft and the second shaft. The control system also includes a first actuator operably connected to the first arm and the first actuator is operable to move the first arm from the first position to the second position. Movement of the first arm moves the first shaft relative to the second shaft to change the position of the second shaft relative to the first shaft.
