The summary describes a guidewire with sensors for measuring physiological parameters and connecting to existing systems. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML functionality. The performance studies focus on functional and safety testing, not algorithmic performance.
No
The device is used to direct a catheter and measure physiological parameters, which are diagnostic functions, not therapeutic.
Yes
The device "measure[s] physiological parameters in the heart and in the coronary and peripheral blood vessel" and connects to a "diagnostic computer." Measuring physiological parameters often serves as a diagnostic function.
No
The device description explicitly states it is a ".014" guidewire with an integrated pressure and temperature sensor," which are hardware components.
Based on the provided information, the PressureWire® is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- PressureWire® Function: The PressureWire® is a device that is inserted into the body (specifically blood vessels) to measure physiological parameters in vivo (within a living organism). It is used to guide a catheter and measure pressure and temperature directly within the blood vessels.
Therefore, the PressureWire® is an invasive medical device used for in vivo measurement, not an in vitro diagnostic test.

Description of the Device:
PressureWire® is a .014" guidewire with an integrated pressure and temperature sensor. together with a detachable cable or transmitter/receiver for connection to a diagnostic computer or a cathlab hemodynamic recording system.
Intended Use of the Device:
PressureWire® is designed to fit inside a percutaneous catheter for the purpose of directing the catheter through a vessel. The signal output from the senor is used for calculation and presentation of any physiological parameters, functions or indices based on temperature or pressure, e.g. Fractional Flow Reserve (FFR). The indication has been modified to address that the device is not only suitable for usage within peripheral and coronary vessels but also for intracardiac measurements within the actual heart.
Indication for Use of the Device:
Pressure Wire® is indicated to direct a catheter through a blood vessel and to measure physiological parameters in the heart and in the coronary and peripheral blood vessel.
Technical Characteristics:
The guidewire part of subject device is identical to the predicate device (K062769).
The new version PressureWire® Aeris, transfer the signal using frequency hoping in the 2.4 GHz frequency radio band, instead of cable. The output from the PressureWire Receiver is compliant with the ANSI/AAMI BP22 standard.

Functional/Safety Testing:
Electrical safety, EMC, radio, sterilization and performance testing indicate that PressureWire® satisfies safety and performance requirements of the device specifications and do not raise additional safety issues.
Conclusion:
On the basis of the testing conducted, it may be concluded that PressureWire® satisfies specified safety and performance requirements. PressureWire® is substantially equivalent to the predicate devices.

Dear Mr. Palmgren:
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.
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
