Intended Use

The Sphincter of Oddi Manometry Module is intended for use by Gastroenterologists or Surgeons to determine intraluminal pressures within the pancreaticobiliary ductal system and motor activity within the sphincter of Oddi zone. The InSIGHT Sphincter of Oddi Manometry Module includes analysis software, but requires skilled interpretation by a physician to make a diagnosis.

Device Story

InSIGHT Sphincter of Oddi Manometry (SOM) Module functions as a recording system for gastrointestinal motility. Input consists of pressure signals from external biliary motility catheters/transducers. System hardware amplifies, isolates, and processes these signals. Analysis software displays waveforms, calculates results, and generates reports. Used in clinical settings by gastroenterologists or surgeons. Physician interprets output to assess pancreaticobiliary ductal pressures and sphincter of Oddi motor activity; aids in clinical diagnosis. Device relies on user training and adherence to labeling to mitigate risks associated with biliary diagnostic procedures.

Clinical Evidence

No clinical data performed; bench testing only. Compliance with design specifications and safety standards (UL 2601-1) verified through internal protocols and outside laboratories.

Technological Characteristics

System includes signal conditioning/recording hardware, analysis software, and external probes/transducers. Designed for use with InSIGHT Model S980000 Gastrointestinal Motility system (K984444). Provides electrical isolation. Complies with UL 2601-1 standard for medical electrical equipment safety.

Indications for Use

Indicated for use by gastroenterologists or surgeons to measure intraluminal pressures in the pancreaticobiliary ductal system and motor activity in the sphincter of Oddi zone. Requires physician interpretation for diagnosis.

Regulatory Classification

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.

# Summary of Safety and Effectiveness

## Introduction

The Safe Medical Device Act (SMDA) of 1990 requires that in addition to other information submitted in a 510(k), medical device manufacturers submit a summary of information regarding safety and effectiveness for the device subject to the 510(k). The summary is to include detailed information regarding adverse health effects of the device. This Summary of Safety and Effectiveness document is intended to comply with the SMDA requirement. FDA will make this summary available to the public within 30 days following a finding of substantial equivalence.

# Comparison to Predicate Devices

The InSIGHT Sphincter of Oddi Manometry (SOM) Module is a manometry recording device with features equivalent in safety and performance to those included on prior legally marketed devices. The InSIGHT SOM Module is Substantially Equivalent to:

K932306 Microinfuser, Manufactured by Sandhill Scientific, Inc.

K900058, Wilson-Cook Biliary Motility Catheter, Manufactured by Wilson-Cook Medical. Inc.

Pre-Amendment, Hewlett-Packard Model 7788-A. Manufactured by Hewlett-Packard Corporation.

## Device Description and Intended Use

The Sphincter of Oddi Manometry Module is intended for use by Gastroenterologists or Surgeons to determine intraluminal pressures within the pancreaticobiliary ductal system and motor activity within the sphincter of Oddi zone. The InSIGHT Sphincter of Oddi Manometry Module includes analysis software, but requires skilled interpretation by a physician to make a diagnosis.

# Technological Characteristics

The SOM Module is intended for use only with the InSIGHT Model S980000 Gastrointestinal Motility system (K984444). The InSIGHT system consists of three basic subsystems. These are:

#### Signal conditioning and recording hardware

This subsystem includes the hardware that amplifies the transduced signals for recording. provides electrical isolation for safety, and processes the signals for subsequent analysis.

#### Analysis software

The software displays the waveforms, shows the analyzed results and incorporates these results into reports.

#### Probes and transducers

These are used to generate the signal that is recorded. Sandhill does not manufacture the transducers and probes that are intended for use with the system, but these carry the manufacturers' approval to market and meet the manufacturers' safety requirements for their use.

The technological characteristics of the InSIGHT SOM Module are the same as, or perform equivalently to, the predicate devices.

# Applicable Standards and Non-Clinical Testing

In compliance with the company's Design Controls procedures, the InSIGHT Model S980000 system has been designed to meet the requirements of the following standard:

{2}------------------------------------------------

Medical Electrical Equipment. Part 1: General Requirements

990441

PAGE 3 OF 3

UL 2601-1: Standard for Medical Electrical Equipment, Part 1: General Requirements for Safety

Certification of the design to the above standards and the device design specifications is through a planned combination of internal design testing to written protocols and outside laboratories. No formal clinical testing has been performed, nor is any believed to be necessary.

# Potential Adverse Health Effects

The InSIGHT SOM Module has been designed to either completely eliminate or mitigate all known health hazards associated with the use of the device. Health hazard risk reduction has been accomplished by rigorous application of a risk management program. One or more of the following means (in order of preference) was used to implement mitigation of health hazards identified by the risk management program:

- 1. Design modifications.
- 2. Detection of hazard conditions and alerting of the user through alarms and visual indications.
- 3. Identification of any potentially undetectable health hazard conditions in the instruction manual and other device labeling.

The user must be qualified in biliary diagnostic procedures, trained in the use of the system, and must be familiar with all labeling and instructions for use associated with the equipment. Many device injuries are due to user error and failure to follow the instructions for use. The user of the device is advised to thoroughly understand the use of the equipment, and familiarize themselves with the location and function of all controls and alarms prior to using the equipment.

Sandhill Scientific believes that the InSIGHT SOM Module is safe and effective when used as instructed by knowledgeable and trained personnel, and performs as well as or better than the legally marketed predicate devices.
