Used by physicians to navigate catheters through coronary and peripheral vasculature while simultaneously measuring physiological pressure parameters. Device connects via a detachable cable to a proprietary programmable diagnostic computer. Output provides real-time pressure data to assist clinicians in hemodynamic assessment during interventional procedures. Benefits include combined guidewire functionality and diagnostic pressure monitoring in a single device. ## Clinical Evidence No clinical data provided; substantial equivalence based on technological characteristics and design similarities to the predicate device. ## Technological Characteristics 0.014" diameter guidewire; 183 or 300 cm length; distal pressure transducer; detachable cable interface; connects to external programmable diagnostic computer. Technological characteristics are identical to the predicate device except for internal dimension modifications. ## Regulatory 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 - PressureWire™ Sensor ([K022188](/device/K022188.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 JUN - 6 2003 Radi Medical Systems AB c/o Mr. Mats Granlund Ouality & Regulatory Affairs Manager Palmbladsgatan 10 SE-754 50 Uppsala Sweden Re: K031662 Trade Name: Pressure Wire™ Sensor Regulation Number: 21 CFR 870.2870 Regulation Name: Catheter tip pressure transducer Regulatory Class: Class II (two) Product Code: DXO Dated: May 26, 2003 Received: May 28, 2003 Dear Mr. Granlund: 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. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such 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. {2}------------------------------------------------ Page 2 - Mr. Mats Granlund 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): good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (301) 594-4646. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97). You may obtain other general information on your responsibilities under the Act from the Division of Small Manufacturers, International and Consumer Assistance at its toll-free number (800) 638-2041 or (301) 443-6597 or at its Internet address http://www.fda.gov/cdrh/dsma/dsmamain.html Sincerely yours, Bram D.
