A mechanics--based perspective on the function of human sphincters during functional luminal imaging probe manometry
Guy Elisha, Sourav Halder, Dustin A. Carlson +4
Functional luminal imaging probe (FLIP) is used to measure cross-sectional area (CSA) and pressure at sphincters. It consists of a catheter surrounded by a fluid filled cylindrical…
Pressure -- area loop based phenotypic classification and mechanics of esophagogastric junction physiology
Guy Elisha, Sourav Halder, Shashank Acharya +5
The esophagogastric junction (EGJ) is located at the distal end of the esophagus and acts as a valve allowing swallowed materials to enter the stomach and preventing acid reflux. I…
A Fully Resolved Multiphysics Model of Gastric Peristalsis and Bolus Emptying in the Upper Gastrointestinal Tract
Shashank Acharya, Sourav Halder, Wenjun Kou +3
Over the past few decades, in silico modeling of organ systems has significantly furthered our understanding of their physiology and biomechanical function. In this work, we presen…
Pumping Patterns and Work Done during Peristalsis in Finite-length Elastic Tubes
Shashank Acharya, Wenjun Kou, Sourav Halder +4
Balloon dilation catheters are often used to quantify the physiological state of peristaltic activity in tubular organs and comment on their ability to propel fluid which is import…
