Robotic catheter system

摘要

A robotic catheter system includes a controller with a master input device. An instrument driver is in communication with the controller and has a guide instrument interface including a plurality of guide instrument drive elements responsive to control signals generated, at least in part, by the master input device. An elongate guide instrument has a base, distal end, and a working lumen, wherein the guide instrument base is operatively coupled to the guide instrument interface. The guide instrument includes a plurality of guide instrument control elements operatively coupled to respective guide drive elements and secured to the distal end of the guide instrument. The guide instrument control elements are axially moveable relative to the guide instrument such that movement of the guide instrument distal end may be controlled by the master input device.

1. A medical instrument system, comprising:
an elongate sheath having a lumen; a working instrument positioned inside and extending through the sheath lumen, the working instrument having a distal end advanceable out of a distal end opening of the sheath lumen, wherein the elongate sheath is steerable independently of the working instrument via multiple control elements; at least one sensor coupled to at least one of the elongate sheath or the working instrument, the at least one sensor configured to determine a contact of at least one of the elongate sheath or the working instrument with an object; a processor in communication with the at least one sensor; and a display in communication with the processor and configured to provide a graphical representation of the contact.
