The summary describes a guidewire with a sensor for measuring physiological parameters and does not mention any AI/ML capabilities or image processing.
No.
The document states that the device is used to measure physiological parameters and to direct a catheter, classifying it as a diagnostic and interventional tool rather than a therapeutic one.
Yes
The device is indicated to "measure physiological parameters in the heart and in the coronary and peripheral blood vessels. Physiological parameters include blood pressure." The device also "connects to a diagnostic computer or a catheter laboratory hemodynamic recording system." Measuring physiological parameters for diagnostic purposes fits the definition of a diagnostic device.
No
The device description explicitly details a physical guidewire with an integrated sensor element, which is a hardware component. The summary also mentions bench testing for physical, mechanical, and coating integrity, further indicating a hardware device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "direct a catheter through a blood vessel and to measure physiological parameters in the heart and in the coronary and peripheral blood vessels." This involves direct measurement of parameters within the patient's body.
- Device Description: The device is a guidewire with an integrated sensor that is "introduced into the patient's blood vessel." This is an invasive device used for in-vivo measurements.
- Lack of In Vitro Activity: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) outside of the body.
IVD devices are specifically designed to perform tests on specimens taken from the body to provide information about a physiological or pathological state. This device performs measurements within the body.

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.

3. PREDICATE DEVICE
- PressureWire™ Certus™ and Aeris™, cleared November 13, 2014 under K140466 .
4. 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
4
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.
5. INDICATIONS FOR 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.
6. PREDICATE DEVICE COMPARISON
PressureWire™ Certus™ and Aeris™ were cleared by FDA under 510(k) K140466 on November 13, 2014. The subject device is substantially equivalent to the predicate device in terms of intended uses, indication for use, operational characteristics, and fundamental design and technology characteristics.
The subject device, PressureWire™ X guidewire, is different from the last previous version of PressureWire™, PressureWire™ Certus™ and Aeris™ in the following ways:
- New Distal Tip Design ●
- New Shipping Box Design ●
- New Single IFU Booklet ●
- New Coating on Sensor Guidewire ●
7. TESTING SUMMARY
The PressureWire™ X guidewire has been tested and is in compliance with ISO 10993-1:2009 with C1:2010), Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process, ISO TS 11135-2:2008, Sterilization of health care products - Ethylene Oxide - Part 2 Guidance on the application of ISO 11135-1, USP 33-NF 28 General chapter Particulate matter in injections, and USP 36 Containers -Plastics.
In addition to the Biocompatibility, Sterilization and Particulate testing performed, design verification and validation was performed on the PressureWire™ X guidewire in compliance with internal design control procedures which included bench testing. This bench testing
5
included physical, mechanical and coating integrity testing for fractures, friction force, and wire diameter and straightness.
The results of this testing concludes the PressureWire™ X guidewire is determined to be safe and effective and is substantially equivalent to the predicate device PressureWire™ Certus TM and PressureWire™ Aeris cleared in K140466.
8. Substantial Equivalence
The fundamental scientific technology for the subject device is the same for predicate device regarding signal transfer, mechanical properties and intended use. PressureWire™ X guidewire is substantially equivalent to the predicated device in intended use, indication for use, fundamental design and technology, and operating principles. Both devices connect to a diagnostic computer or a catheter laboratory hemodynamic recording system to enable measurements of physiological parameters with minor design changes incorporated into the PressureWire™ X guidewire from the predicate device:
- New Distal Tip Design
- New Shipping Box Design
- New Single IFU Booklet ●
- New Coating on Sensor Guidewire
The subject device, PressureWire™ X Guidewire, meets the design inputs and raises no new safety or efficacy concerns. PressureWire™ X Guidewire is determined to be substantially equivalent to the presently marketed predicated device, K140466.
9. Conclusion
The results of these activities demonstrate that the PressureWire™ X Guidewire is as safe, as effective, and performs as well as or better than the predicate device.
