ENDOSCOPIC SYSTEMS WITH LOW CAPACITANCE AND/OR ELECTROMAGNETIC SHIELDING, AND RELATED METHODS

摘要

An endoscopic system can include an endoscope shaft having a proximal end and a distal end, and an electrically active sensor system including at least one sensor mounted proximate the distal end and positioned to sense at least one characteristic of an environment in which the distal end is located. The capacitance of the sensor system relative to earth ground maintains current leakage to a level that meets requirements of a cardiac float rating.
