Acute Wired Colonic Monitor of Conscious Activity (ColoMOCA) implantation in pig bowel

Study Purpose: This study aims to develop a tool to measure bowel fullness and activity. This data was collected while testing bowel function using the Colonic Monitor of Conscious Activity (ColoMOCA) bowel sensor device.

Data Collection: This dataset consists of 2 animals in acute experiments. A wired, ColoMOCA device was placed in a pig's rectum and then bowel. The device was wired for power but transmitted data wirelessly to a receiving antenna (chataMOCA). Data transmitted included pressure (2 pressure sensors on ColoMOCA device), conductivity, conductance, and capacitance.

Primary Conclusion: The UroMOCA device measured and transmitted bowel function wirelessly and catheter-free in conscious ambulating animals.

Curator's Notes

Experimental Design: This study used a domestic Yorkshire pig that had a cystotomy and then had a UroMOCA device placed in the rectum and bowel. The catheter reduces the pressure that a bladder with urine would put on the colon. Conductivity, conductance, and capacitance testing were performed using 4 electrode on the ColoMOCA in response to the device being in contact with real and artificial stool.

Completeness: This dataset is a part of a larger study: "A FitBit for the bladder."

Subjects & Samples: This particular dataset used two 16 week old male domestic Yorkshire pigs (n=2). Measurements were taken in vivo in conscious ambulating animals.

Primary vs derivative data: The primary folder includes testing the pressure and volume (conductance, conductivity, and capacitance) in the rectum and bowel using the ColoMOCAdata as tsv files. The derivative folder contains summarized data in both tabular and graphical form(xlsx, jpg).
