Robotically augmented catheter manipulation handle
First Claim
1. A hand-held catheter apparatus, comprising:
- a handle body extending from a proximal end to a distal end along a longitudinal axis;
a user input interface on an outer surface of the handle body, wherein the user input interface generates a rotation command signal in response to user input at the user input interface;
a rotational actuator module positioned in the handle body and having a rotatable output, wherein the rotational actuator module controls an angular rotation of the rotatable output in response to the rotational command signal;
a handle coupling disposed at the distal end of the handle body and configured to releasably couple to a replaceable catheter head at a proximal end of a disposable catheter structure adapted to extend distally therefrom, wherein when the handle coupling is engaged with the catheter head, the rotational actuator module is operative to rotate the catheter structure about the longitudinal axis in response to rotation of the rotatable output, wherein the handle coupling comprises a handle deflection interface adapted to releasably couple to a catheter deflection interface in the catheter head;
a first deflection actuator disposed in the handle body and configured to impart, via the handle deflection interface and the catheter deflection interface, a first deflection angle command in a first plane to a steerable tip at a distal end of the catheter structure.

Abstract
Apparatus and associated methods relate to a catheter manipulation handle with user interface controls for steering a catheter in situ while providing an augmented (e.g., motorized, powered and tunable precision steering, and perforation safeguards) control and feedback user experience. In an illustrative example, the catheter manipulation handle may provide motor assisted operation to automatically rotate and/or deflect a distal tip of the catheter to steer and guide the distal tip to a target location in the patient'"'"'s vasculature system. The augmented feedback may include, for example, haptic feedback via the handle. Haptic, audible, and/or visual feedback via the handle may indicate, for example, proximity or engagement of the distal tip with sensitive tissue. In some examples, the handle'"'"'s augmented operation may advantageously amplify feedback signals to enhance the user'"'"'s perception of the patient'"'"'s safety with respect to the safe passage of the distal tip through the patient'"'"'s vasculature.
