What changed
USPTO issued patent US12605051B2 to EndoVista, Inc. for a control device for steerable medical devices. The patent covers a steering shaft with two steering cams (one fixed, one freely rotatable), a latch assembly that toggles between un-tensioned and tensioned states for steering wires, and a rotary knob assembly. CPC classifications span endoscopic and surgical control devices.
Medical device manufacturers developing steerable instruments such as endoscopes, laparoscopes, or catheter-based systems should review this patent when assessing freedom-to-operate for similar control mechanisms. The dual-cam latch design described in the claims may represent a proprietary approach to tensioning steering wires in minimally invasive surgical devices.

Abstract
A control device for use with a steerable medical device comprises a steering shaft rotatable about a longitudinal axis thereof, a first steering cam is affixed to the steering shaft to rotate in unison therewith. A second steering cam is mounted on the steering shaft and freely rotatable about the longitudinal axis of the steering shaft independent of the steering shaft. A latch assembly is operatively connected to the first steering cam and the second steering cam and operable in an inactive configuration in which the first and second steering cams are positioned to maintain first and second steering wires in an un-tensioned or reduced tension state, and further operable in an active configuration in which the first and second steering cams are positioned to maintain the first and second steering wires in a tensioned state. A rotary knob assembly is also disclosed.
