Patent ID: 8491567

Claim:
A handle mechanism for a manually steered catheter for a system for imaging, diagnosing, and/or treating an area of interest in a patient's body, comprising: an assembly attached to an imaging, diagnosing, and/or treating device of the manually steered catheter, whereupon activation of the assembly by a user the assembly functions to rapidly rotate the imaging, diagnosing, and/or treating device; whereupon activation of the assembly by a user the assembly further functions to translate the imaging, diagnosing, and/or treating device along the central longitudinal axis of the imaging, diagnosing, and/or treating device; and a switch mechanism for switching between a rotation mode in which activation of the assembly by a user causes the assembly to rapidly rotate the imaging, diagnosing, and/or treating device only and a rotation/translation mode in which activation of the assembly by a user causes the assembly to rapidly rotate the imaging, diagnosing, and/or treating device and to translate the imaging, diagnosing, and/or treating device along the central longitudinal axis of the imaging, diagnosing, and/or treating device.
