Abstract
A medical device control handle has a first actuation assembly and a second actuation assembly, wherein each assembly has a shaft that is axially aligned but not rotationally coupled with the other shaft. The first actuation assembly includes a first actuation member and a clutch mechanism having a friction disk for generating frictional torque in rendering the first actuation member self-holding. The first actuation member has a cam portion adapted to impart translational motion and rotational motion for disengaging the clutch mechanism upon pivotation of the first actuation member, thus allowing rotation of the first shaft to manipulate a feature of the medical device, for example, deflection. The second actuation assembly includes a second actuation member and a translating member that is responsive to rotation of the second shaft so as to manipulate another feature of the medical device. The second actuation member is also self holding.
