Abstract
The cross-correlation of corresponding signals facilitates the development of sensor nanotechnologies including a catheter for performing ablation of cardiac arrhythmias and a biocompatible electrical interface with monitoring capabilities. Cross-correlation of data acquired with differing techniques enables system calibration and design, as well as, validation of the data acquired with next generation sensors. In a preferred mode of the invention, novel cardiac nanosensors enable an operator to differentiate one individual patient'"'"'s cardiac tissue mechanical properties from others by using a sense of touch much as clinicians today use auditory cues with a stethoscope.

6. A haptic control system with haptic handle feedback, comprising:
-
a catheter adapted to be insertable into a vasculature of a patient, the catheter having a distal end that includes at least one microfabricated sensor; a handle coupled to a proximal end of the catheter; a haptic component associated with the handle that provides at least one of a vibratory and a motion sensation to an operator of the handle; and a processor coupled to the handle, the processor configured to receive signals from the at least one microfabricated sensor and transform the signals into haptic representations of tissue motion by driving the haptic component, the haptic representations having an amplitude dependent on the magnitude of a real time parameter as sent by the at least one microfabricated sensor. - View Dependent Claims (7, 8, 9, 10, 11, 12)
