Intended Use
The PressureWire™ X guidewire 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 vessels. Physiological parameters include blood pressure. The PressureWire™ X guidewire can also measure blood temperature.
Device Description
The PressureWire™ X guidewire has an integrated sensor element at the tip to enable measurements of physiological parameters. The wire is introduced into the patient's blood vessel. A torque device is used to steer the wire and sensor into the required position for pressure measurements according to standard clinical practice. PressureWire™ X guidewire is available in two different lengths. The guidewire is uniquely paired with a specific connection cable or with a specific transmitter. Both PressureWire™ X guidewire connection configurations connect to a diagnostic computer or a catheter laboratory hemodynamic recording system. The PressureWire™ guidewire is designed to fit inside a percutaneous catheter for the purpose of directing the catheter through a vessel. The signal output from the sensor is transmitted to associated equipment for analysis, calculations, and display of physiological parameters or indices based on pressure or temperature, e.g. Fractional Flow Reserve (FFR).
More Information

Not Found

No
The summary describes a guidewire with a sensor for measuring physiological parameters and transmitting the signal for analysis and display. There is no mention of AI or ML in the device description, intended use, or performance studies. The analysis and calculations mentioned are likely standard physiological calculations (e.g., FFR) based on the measured pressure and temperature, not AI/ML-driven analysis.

No
The device is described as a guidewire indicated to direct a catheter and to measure physiological parameters for diagnostic purposes, not for treating a condition.

Yes
The device is indicated to measure physiological parameters (blood pressure, blood temperature) in the heart and blood vessels, and the output is used for analysis, calculations, and display of these parameters, which is characteristic of a diagnostic device.

No

The device description explicitly states it is a guidewire with an integrated sensor element at the tip, which is a physical hardware component. It also mentions a torque device and connection cables/transmitters, further indicating it is not software-only.

Based on the provided information, the PressureWire™ X guidewire is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening.
  • PressureWire™ X Function: The PressureWire™ X guidewire is an invasive device that is introduced into the patient's blood vessels (in vivo) to directly measure physiological parameters like blood pressure and temperature. It does not analyze samples taken from the body.

The device is clearly described as being used within the patient's circulatory system to gather real-time physiological data. This is characteristic of an in vivo diagnostic or monitoring device, not an in vitro diagnostic device.

Dear Josh Johnson:

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.

guidewire can also measure blood temperature.
Comparison of
Subject to Predicate
Device:A minor design modification was made to the pressure sensor jacket component of the
PressureWire™ X guidewire. Specifically, the sensor jacket design changed from a one-
window to a three-window jacket design, and the window length was extended. The
sensor jacket is located near the distal tip of the PressureWire™ X, and functions to
protect the pressure sensor. The openings in the sensor jacket, or windows, function to
allow fluid flow to the sensor. There were no other changes to the device or IFU.
