Handle 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 first shaft and the second shaft connected to a medical device, the medical device having a first configuration and a second configuration, the control system comprising:
- a rotatable gear, the rotatable gear comprising a plurality of protrusions;
a first movable member operably connected to the gear and the first shaft; and
a second movable member operably connected to the gear and the second shaft;
wherein rotation of the rotatable gear moves the first movable member relative to the second movable member in opposite directions and an equal distance from a central axis of the control system to change a position of the first shaft relative to the second shaft and equal and opposite force is removed from the medical device to change the medical device from the first configuration to the second configuration.

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 rotatable gear operably connected to a first movable member and a second movable member movable by the rotatable gear. The first movable member is operably connected to the first shaft and the second movable member operably connected to the second shaft. The first movable member moves the first shaft and the second movable member moves the second shaft to change a position of the first shaft relative to the second shaft and to change a configuration of a medical device operably connected to the first shaft and the second shaft.

13. A stent delivery system comprising:
-
a first shaft; a second shaft, the second shaft movable relative to the first shaft and coaxially extending with the first shaft; a stent operably connected to the first shaft and the second shaft; and a control system comprising; a rotatable gear; a first movable member operably connected to the gear and the first shaft; and a second movable member operably connected to the gear and the second shaft; wherein rotation of the rotatable gear moves the first movable member and the second movable member in opposite directions and an equal distance from a central axis of the control system to change a position of the first shaft relative to the second shaft and equal and opposite force is removed from the stent to change a configuration of the stent operably connected to the first shaft and the second shaft from a constrained configuration to an expanded configuration. - View Dependent Claims (14, 15)

16. A method of controlling the movement of a medical device delivery system, the method comprising:
-
providing a control system, the control system comprising; a rotatable gear, the rotatable gear comprising a plurality of protrusions; a first movable member operably connected to the gear and a first shaft; and a second movable member operably connected to the gear and a second shaft; activating the rotatable gear to move the first movable member relative to the second movable member in opposite directions and an equal distance from a central axis of the control system; changing the position of the first shaft relative to the second shaft; and changing a configuration of a medical device connected to the first shaft and the second shaft when the first shaft is moved relative to the second shaft and equal and opposite force is applied to or removed from the medical device. - View Dependent Claims (17, 18, 20)
