Abstract: A computer-assisted medical device is configured and used to endoluminally navigate to a location in the gastrointestinal system and there treat certain body lumen wall areas while avoiding other body lumen wall areas. Embodiments ablate the inner mucosal layer and sub-mucosal nerve plexus of the stomach, duodenum and jejunum to effect treatment of insulin resistance and metabolic disorders, such as Type II diabetes (T2D), polycystic ovarian syndrome (PCOS), non-alcoholic steatohepatitis (NASH), non-alcoholic fatty liver disease (NAFLD), congestive heart failure (CHF) and obstructive sleep apnea (OSA). Various sensors are used to assist a clinical operator to navigate from the mouth through the pyloric sphincter and into and through the duodenum and/or jejunum. Various sensors are used to map and identify portions of the duodenum and/or jejunum. Various lumen wall ablation devices and methods are described. Various post-treatment assessments are described.

Abstract: An apparatus is provided to detect electrical contact between anatomical tissue and a shield conductor: a transformer; an alternating current (AC) reference frequency signal generator to inject a reference frequency signal to a primary winding of the transformer; a reactive impedance coupled in parallel with a secondary winding of the transformer between a first node and a second node; and a phase match detector circuit to detect a phase match between the reference frequency signal and a reflected reference frequency signal that is reflected from the secondary winding to the primary winding.

Abstract: A method is provided to seal and cut biological tissue. An alternating current (AC) scaling signal is imparted between a set of sealing electrodes. An AC cutting signal is imparted between a set of cutting electrodes in response to a biological tissue impedance between the sealing electrodes reaching a first impedance threshold value. The AC scaling signal is halted at an end of a time interval, beginning while the AC cutting signal is imparted between the cutting electrodes, in response to impedance of the biological tissue disposed between the set of sealing electrodes reaching a second impedance threshold value.
