Intended Use

The Mikro-Cath Pressure Catheter is a single-use catheter intended to be used for medical research and diagnostic purposes. The catheter is indicated to measure cardiovascular, intracompartmental, and airway pressures in the human body. The catheter is used as a minimally invasive device under short term limited body contact (<24 hours).

Device Story

Mikro-Cath Pressure Catheter is a single-use, minimally invasive device for measuring cardiovascular, intracompartmental, and airway pressures. A pressure sensor mounted at the distal tip converts sensed pressure or sound into an electrical output signal. The proximal end features a connector for signal transmission. Used in research and diagnostic settings, the device provides real-time pressure data to healthcare providers or researchers to assist in clinical decision-making and physiological monitoring. The device is intended for short-term body contact (<24 hours).

Clinical Evidence

No clinical data provided. No FDA performance standards established. Substantial equivalence is based on identical technological characteristics to the predicate device.

Technological Characteristics

Single-use catheter with a pressure sensor at the distal tip. Electrical output signal proportional to sensed pressure/sound. Proximal connector. Materials, mechanical, and electrical characteristics are identical to K093111.

Indications for Use

Indicated for use in humans for medical research and diagnostic purposes to measure cardiovascular, intracompartmental, and airway pressures. Minimally invasive, short-term use (<24 hours).

Regulatory Classification

Identification

A catheter tip pressure transducer is a device incorporated into the distal end of a catheter. When placed in the bloodstream, its mechanical or electrical properties change in relation to changes in blood pressure. These changes are transmitted to accessory equipment for processing.

Predicate Devices

• Mikro-Cath (K093111)
• Transpac III Disposable Straight Pressure Transducer (DSPT) (K061573)
• Mikro-Tip Catheter Pressure Transducer (K830909)

Dear Allison Komiyama:

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 indications 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 Cosmetic 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 general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical devicerelated adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in

{1}------------------------------------------------

the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Division of Industry and Consumer Education at its toll-free number [phone] or [phone] or at its Internet address

http://www.fda.gov/MedicalDevices/ResourcesforYou/Industry/default.htm. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to

http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.

an electrical output signal which varies in direct proportion to the magnitude of sense pressure or sound.

#### PREDICATE DEVICE IDENTIFICATION

The Mikro-Cath Pressure Catheter is substantially equivalent to the following predicates:

| 510(k)<br>Number | Predicate Device Name / Manufacturer | Primary<br>Predicate |
|------------------|-----------------------------------------------------------------------------|----------------------|
| K093111 | Mikro-Cath / Millar Instruments, Inc. | ✓ |
| K061573 | Transpac III Disposable Straight Pressure Transducer (DSPT) / Hospira, Inc. | |
| K830909 | Mikro-Tip Catheter Pressure Transducer / Millar Instruments, Inc. | |

## SUMMARY OF NON-CLINICAL AND CLINICAL TESTING

No FDA performance standards have been established for the Mikro-Cath Pressure Catheter. No additional testing was provided in this submission in order to demonstrate substantial equivalence.

## EQUIVALENCE TO PREDICATE DEVICES

Millar believes that the Mikro-Cath Pressure Catheter is substantially equivalent to the predicate devices based on the information summarized here:

The subject device has identical design and dimensions, and uses similar or identical materials as the device cleared in K093111. The patient contacting materials, mechanical characteristics, and electrical characteristics of the subject device have not changed from the predicate device cleared in K093111. The subject device has the same or similar indications for use as the devices cleared in K093111, K061573, and K830909.

## CONCLUSION

The Mikro-Cath Pressure Catheter is considered substantially equivalent to the predicate devices based on identical technological characteristics. While the subject device has expanded indications (i.e. it may be used to measure intracompartmental and airway pressure), the subject device does not raise new issues of safety or efficacy compared to the predicate devices.
