The summary describes a system that measures and analyzes pressure data using standard signal processing and parameter estimation techniques, without mentioning AI or ML.
No
The device is used for sensing pressures and providing analysis information for diagnostic purposes, not for treating or rehabilitating a condition.
Yes
The device obtains high-resolution pressure mapping within gastrointestinal organs and provides analysis information and estimated parameters (like LES location, pressure, and motility metrics). This data is then viewed by a physician for "diagnostic and analysis purposes," directly supporting physician diagnosis.
No
The device description explicitly states that the system includes a "catheter probe with 36 pressure sensing elements" and "MVS interface electronics," indicating the presence of hardware components beyond just software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze specimens taken from the human body. The description clearly states that the Motility Visualization System obtains pressure measurements within the tubular organs of the gastrointestinal tract using a catheter inserted into the body. This is an in vivo measurement, not an in vitro analysis of a specimen.
- The device measures physical parameters directly within the body. It senses and records pressure, which is a physical characteristic of the organ's function, not a chemical or biological marker from a sample.
The device is a diagnostic tool used in a clinical setting, but its method of operation (measuring pressure in vivo) places it outside the definition of an In Vitro Diagnostic.

Intended Use / Indications for Use
The Motility Visualization System obtains a high resolution mapping of pressures within tubular organs of the human gastrointestinal tract. These organs include the esophagus from the pharyngeal region through the stomach, the duodenum, and the anus/rectum. It is used in a medical clinical setting to sense the pressures and store the corresponding data. The system also provides analysis information. The real time data as well as the analysis information can be viewed by a physician for diagnostic and analysis purposes.

Device Description
The Motility Visualization System (MVS) obtains a high resolution mapping of pressures within tubular organs of the gastrointestinal tract. It is used in a medical clinical setting to sense the pressures along the gastrointestinal tract and stores the corresponding data. The system also provides analysis information. The real time data as well as the analysis information can be viewed by a physician for diagnostic and analysis purposes.
The system includes a catheter probe with 36 pressure sensing elements. During the clinical procedure, the catheter is inserted transnasally and pressures inside the upper esophageal sphincter (UES), esophagus, lower esophageal sphincter (LES), and proximal gut are measured as the patient typically swallows small amounts of water. Alternatively, the catheter may be inserted in the anus/rectum for measurement of contractile pressures in that region. Real-time data is sampled from each sensing element via the MVS interface electronics and made available to the MVS software during each sample period. The software displays the data in real-time to support the clinical procedure.
The software also supports operational utility functions such as providing the user an interface for operating the pressure calibration system. It obtains the catheter sensor and calibration chamber data during the calibration process and determines the correction factors to be used in subsequent data collection.
The MVS supports physician diagnosis and analysis by mcans of a playback function, which replays a stored session using previously recorded data instead of real-time data. The MVS also indicates estimated parameters such as LES location, LES resting pressure, LES relaxation, LES residual pressure inversion point (PIP) location, UES pressure, and motility metrics such as peristaltic wave amplitude, duration and velocity.
The primary MVS functions are:
- Calibrate the pressure sensors ●
- . Provide user interface displays, prompts, and controls
- Collect pressure data .
- Display and store collected data .
- Replay stored data .

(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)
Classification. Class II (performance standards).

Intended use:
The MVS obtains a high resolution mapping of pressures within tubular organs of the human gastrointestinal tract. These organs include the esophagus from the pharyngeal region through the stomach, the duodenum, and the anus/rectum. It is used in a medical clinical setting to sense the pressures and store the corresponding data. The system also provides analysis information. The real time data as well as the analysis information can be viewed by a physician for diagnostic and analysis purposes.
The system includes a catheter probe with 36 pressure sensing elements. During the clinical procedure, the catheter is inserted transnasally and pressure inside the pharynx, esophagus, or proximal gut (stomach/duodenum) is measured as the patient typically swallows small amounts of water. Alternatively, pressures within the anus/rectum are measured via rectal intubation. Real-time data is sampled from each sensing element via the MVS interface electronics and made available to the MVS software during each sample period. The software displays the data in real-time to support the clinical procedure.
Summary of technological characteristics:
The MVS catheter is equivalent to the Medtronic catheter which is manufactured by the same company. Konigsberg Instruments. The primary difference being the larger number of pressure sensors (typically 4-16 for the predicate device and 36 for the applicant device). The MVS system uses a proprietary signal processing scheme to minimize the number of electrical conductors.
The user interface is via touch screen display, keyboard and mouse and the use of a hard drive that allows recording and play back of the data. By providing more data, the system gives a more complete pressure data set of the esophagus. The system can also be used if there are inactive sensors.
