The description focuses on the mechanical and gas-powered aspects of the pump for pressure measurement, with no mention of AI or ML for analysis or interpretation.
No
The device is described as a perfusion pump designed to facilitate the monitoring and analysis of intragastrointestinal pressures. It is used in conjunction with a manometric assembly to gather information about pressure patterns, which aids in determining patient management or for research. It does not actively treat or alleviate a medical condition.
Yes
The device is used to monitor and analyze intragastrointestinal pressures, providing information for determining appropriate patient management, which is a diagnostic purpose.
No
The device description explicitly states it is comprised of a constant gas pressure delivery system and a constant flow constant pressure, multi-channel, perfusate system, which are hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, tissue) to provide information for diagnostic purposes.
- Device Function: The Mark II CO2 Manometric Perfusion Pump & Mark II Manometric Perfusion Pump are described as gas-powered perfusion pumps designed to facilitate the monitoring and analysis of intragastrointestinal pressures. They work in conjunction with a catheter inserted into the body.
- Lack of Specimen Analysis: The device does not analyze specimens taken from the body. It is used to measure pressures within the gastrointestinal tract.
Therefore, the device's function and intended use fall outside the scope of In Vitro Diagnostics. It is a device used for physiological measurement in vivo.

Intended Use / Indications for Use
The Mark II Manometric Perfusion Pump is used to provide a low compliant fluid pathway to enable high fidelity dynamic intragastroesophageal pressured and analyzed in both pediatric and adult populations when used with a gastrointestinal motility catheter. The product is to be used on patients in the hospital environment under supervision of a trained physician.
When used in conjunction with a gastrointestinal manometric assembly (catheter), the Mark II CO2 Manometric Perfusion Pump & Mark II Manometric Perfusion Fump, can be used where gastrointestinal manometry is indicated when the following conditions are satisfied;
-
When information about patterns of gastrointestinal pressures is judged to be of importance for either determining appropriate patient management or for research studies into gastro-intestinal motility.
-
Contra-indications are considered, and the risk-bencht analysis is judged to favour performance of the manometric study, after measures have been taken to minimise all possible risks.

§ 876.1725 Gastrointestinal motility monitoring system.
(a)
Identification. A gastrointestinal motility monitoring system is a device used to measure peristalic activity or pressure in the stomach or esophagus by means of a probe with transducers that is introduced through the mouth into the gastrointestinal tract. The device may include signal conditioning, amplifying, and recording equipment. This generic type of device includes the esophageal motility monitor and tube, the gastrointestinal motility (electrical) system, and certain accessories, such as a pressure transducer, amplifier, and external recorder.(b)

An improved catheter infusion system is needed for esophageal intraluminal manometry. Using conventional syringe pump infusion systems undesirably rapid infusion rates of 6ml/min or more are often needed to achieve accurate recording of esophageal peristaltic pressure. These rapid baseline infusion rates are necessitated by the high compliance of syringe pump systems which causes substantial reduction in the infusion rate during dynamic pressure transients. In this study we tested a hydraulic capillary infusion system designed to have low compliance. This minimally compliant system yields accurate recording of esophageal peristaltic pressure at infusion rates of 0.6 ml/min or less. We believe that the hydraulic capillary infusion system is a useful tool for performing both clinical and investigative studies of esophageal motor function.

Abstract
Syringe pumps are almost universally used for constant perfusion oesophageal manometry, despite important technical limitations. A pneumatically driven perfusion pump has been designed specifically for oesophageal manometry. This pump requires less than one third the flow setting of a syringe pump to achieve a given rate of pressure rise. It is simple to operate and needs infrequent refilling. Nearly two years' practical experience with this pump has confirmed its superiority over the syringe pump for constant perfusion manometry.
