Patent ID: 8105337

Claim:
A user control for a medical electrical lead implant tool, the implant tool comprising an elongate shaft, a gripping assembly terminating a distal end of the shaft and adapted to alternately grasp the lead and release the lead and to rotate the lead, and a drive cable coupled to the gripping assembly and extending proximally therefrom within the shaft; the user control terminating the proximal end of the shaft and comprising: a stationary handle including a body and fingers extending distally therefrom; a shaft guide member coupled to the shaft and to the fingers of the stationary handle, the shaft guide member abutting the fingers to form a window in between the shaft guide member and the body of the stationary handle; and a slidable and rotatable dial coupled to a proximal end of the drive cable, the dial being positioned between the fingers of the stationary handle and protruding out through the window; wherein the user control facilitates single-handed manipulation of the slidable and rotatable dial, which may be grasped by fingers of a hand for longitudinal and rotational manipulation when the stationary handle is held in a palm of the hand; the longitudinal manipulation causing the gripping assembly, via the drive cable, to alternately grasp the lead and release the lead and the rotational manipulation causing the gripping assembly, via the drive cable, to rotate the lead.
