The FLEXILOG LS is used for the location of the lower esophageal sphincter and the measuring of the nares to lower esophageal sphincter distance. This procedure being carried out prior to the accurate placement of a pH sensitive catheter for an ambulatory pH study to quantify gastroesophageal reflux.
The FLEXILOG LS is a single channel, pressure monitoring system comprising of a module of electronics that provides transducer excitation, amplification and transmission of the signal to a computer via an optically isolated RS232 connector. The pressure signal is displayed on the computer VDU via a Microsoft Windows display program. The program does not provide any analysis or data saving options. The electronics module is designed to be compatible with catheter tip and water perfused pressure transducers currently available in the US market.
This document is a 510K submission for the FLEXILOG LS device, a Lower Esophageal Sphincter Detector. The provided text outlines the device's description, indications for use, and technological characteristics, along with a claim of substantial equivalence to predicate devices. However, it does not contain the detailed study information required to answer your questions about acceptance criteria, specific performance metrics, sample sizes, ground truth establishment, or specialized studies like MRMC or standalone performance evaluations.
The only statement related to performance and testing is: "The FLEXILOG LS has been shown to accurately measure and display pressure." This sentence is too vague to extract specific acceptance criteria or study details.
Therefore,Based on the provided text, I cannot answer your questions as the document does not contain the detailed study results, acceptance criteria table, sample sizes, ground truth information, or specific study types (e.g., MRMC, standalone) you are looking for. The document only states that "The FLEXILOG LS has been shown to accurately measure and display pressure," which is a general claim and not specific performance data.

Indications
The FLEXILOG LS is used for the location of the lower esophageal sphincter and the measuring of the nares to lower esophageal sphincter distance. This procedure being carried out prior to the accurate placement of a pH sensitive catheter for an ambulatory pH study to quantify gastroesophageal reflux.
Technological Characteristics
The FLEXILOG LS is a single channel pressure measuring system similar to those in the predicate devices RMS III, the LES Locator, Digitrapper MK III and Digitrapper MD. However, the electronics are contained in a standalone box, not contained within the ambulatory pH recorder box as in the RMS II, Digitrapper MK III and Digitrapper MD. Nor does it require to be connected to a pH recorder as does the LES locator. Pressure data is displayed on a computer screen as with the multi channel Biolab and PC Polygraph HR systems.
Testing
The FLEXILOG LS has been shown to accurately measure and display pressure.

§ 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)
Classification. Class II (performance standards).
