Treatment of Ex-vivo Small Bowel Mucosa With a Dedicated Radiofrequency Ablation (SB-RFA) Catheter.

"The samples will be spread and fixed using needles. The prototype RFA-SB ablation catheter will be applied by the PI as follows to each section of duodenum, jejunum and ileum.~The treating paddle of the prototype RFA-SB catheter will be pushed on the small bowel mucosa exerting the same pressure that would be applied endoscopically.~12 J/cm2 will be applied every time with a 20 second interval between applications to simulate clinical practice.~There will be two single applications to two separate specimen sites. There will be two double applications to two separate specimen sites. There will be two triple applications to two separate specimen sites. There will be two quadruple applications to two separate specimen sites."
