  User interface for remote control of medical devicesUSPTO Application #: 20060025679Title: User interface for remote control of medical devices Abstract: An interface for remotely controlling a medical device in a patient's body provides a two dimensional display of a three dimensional rendering of the operating region, and allows the user to select the orientation or location of the distal end of the medical device on the display and then operate a navigation system to cause the distal end of the medical device to approximately assume the selected orientation or location.

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims benefit of U.S. Provisional Application Ser. No. 60/576,946, filed Jun. 4, 2004, incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] This invention relates to the remote navigation of medical devices in a patient's body, and in particular to a user interface for controlling a remote navigation system. [0003] Advances in technology have resulted in systems that allow a physician or other medical professional to remotely control the orientation of the distal of a medical device. It is now fairly routine steer the distal end of a medical device inside a patient's body by manipulating controls on the proximal end of the medical device. Recently magnetic navigation systems have been developed that allow a physician to orient the distal end of a medical device using the field of an external source magnet. Other systems have been discussed for the automated remote orientation of the distal end of a medical device, for example by operating magnetostrictive or electrostrictive elements incorporated into the medical device. However the medical device is oriented, it is still difficult for a physician to visualize the procedure site (which is out of view inside the patient's body), to selected the desired direction in which to orient the distal end of the medical device and communicate the selected direction to the system in order to orient the distal end of the medical device in the selected direction. SUMMARY OF THE INVENTION [0004] The present invention relates to an interface to facilitate the selection of the desired direction in which to orient the distal end of the medical device and to communicate the selected direction to a navigation system in order to orient the distal end of the medical device in the selected direction. While the present invention is described primarily in connection with a magnetic navigation system, the invention is not so limited, and can be used in connection with other navigation systems, such as those that can orient the distal end of a medical device with mechanical means, electrostrictive elements, magnetostrictive elements, or otherwise.
