• Device Class: Class 2

Intended Use

The catheter probe is used to obtain a high resolution mapping of peristaltic activity or pressure within the organs of the gastrointestinal tract, and to allow storage of the corresponding data. The device is manufactured in the basic model variations listed below: 1. High Resolution Gastrointestinal Catheter with up to 40 pressure sensors: This model variation is intended for simple direct esophageal pressure, either at, above, or below the specific site of interest. Pressure information is provided at multiple sensor sites. Pressures may be measured continuously, at rest, or dynamically. 2. Gastrointestinal catheter, with pH sensors: This model variation is the same as the High Resolution Gastrointestinal (GI) catheter described above, except that this model variation includes up to 7 pH sensors. PH probes are added to allow measurements of pH in the stomach and/or esophagus. 3. Gastrointestinal catheter, with sleeve: This model variation is the same as the High Resolution Gastrointestinal (GI) catheter described above, except one or more of the pressure sensor sites will include a sleeve. The sleeve is added to broaden the pressure sensitive one for the sensor site, and reduce positioning sensitivity. 4. Gastrointestinal catheter, with impedance rings: This model variation is the same as the High Resolution Gastrointestinal (GI) catheter described above, except it includes up to 14 conductive rings for impedance studies. 5. Gastrointestinal catheter, with lumen: This model variation is the same as the High Resolution Gastrointestinal (GI) catheter described above, except it includes a lumen.

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.

#### Proprietary Name of Device

UniTip High Resolution GI Catheter

#### Classification Name

Gastrointestinal motility monitoring system

#### 510(k) Classification

Class II FFX

#### Device Description and Intended Use

The Unisensor UniTip Gastrointestinal Pressure Sensor Catheter product line consists of multiple ultra-miniature solid-state pressure sensors, located at the distal end of a gastrointestinal catheter. pH sensors, silicon rubber sleeves, lumen, and conductive impedance rings, may also be included. There are scanning electronics for multiplexing the sensor signals, and an electrical connection located at the proximal end to carry the sensor element signals to an external gastrointestinal motility recording equipment. The UniTip GI catheters are produced in various lengths and catheter sizes.

This modification consists of increasing the maximum number of pressure sensor elements to 40. The closer proximity of the pressure sensor elements to each other allows for high-resolution

mapping of pressures within the organs of the human gastrointestinal tract. This modification also increases the maximum number of pH sensors to 7, and the maximum number of impedence rings to 14.

### Predicate Devices

Unisensor AG, UniTip Pressure Sensor Catheter K003580

Sierra Scientific Instruments, Inc., Motility Visualization System K031169

### Biocompatibility

The requirements of the following standards have been used in part to establish substantial equivalence:

EN 30993-1/ISO 10993-1 "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing"

The company did not conduct, nor depend on, clinical studies in order to establish substantial equivalence.

### Risk Management

This device has been designed to either completely eliminate or mitigate 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.

Unisensor AG believes that the UniTip High Resolution GI Catheter is safe and effective when used as instructed by knowledgeable and trained personnel, and is substantially equivalent to the legally marketed predicate devices.

Dear Mr. Clark:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indivious for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Coometic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The greeral controls provisions of the Act include requirements for annual registration, listing of devines, good manufacturing practice, labeling, and prohibitions against misbranding and adulter of on.
