The device description and performance studies focus on the physical properties and biocompatibility of a guidewire, with no mention of AI or ML.
No.
The device is used for "introduction and positioning of catheters," which is a diagnostic or procedural step, not a therapeutic action performed by the guidewire itself. The "therapeutic applications" refer to the eventual use of the catheter guided by this device.
No.
The device is a guidewire used for positioning catheters in therapeutic and diagnostic applications, but it does not perform diagnostic functions itself.
No
The device description clearly states it is a physical guidewire made of stainless steel or Ni-Ti alloy with a hydrophilic coating, and the performance studies involve physical testing of the wire's properties. There is no mention of software as the primary component or function.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "introduction and positioning of catheters within the peripheral vasculature in vascular diagnostic and therapeutic applications." This describes a device used within the body for medical procedures, not for testing samples outside the body.
- Device Description: The description details a physical guidewire with specific materials, coatings, shapes, and dimensions. This is consistent with an invasive medical device, not a diagnostic test kit or instrument used for analyzing biological samples.
- Performance Studies: The performance studies focus on physical properties of the guidewire (tensile strength, torque, flexibility, coating adherence) and biocompatibility. These are relevant to the safety and function of a device used in the body, not the analytical performance of a diagnostic test.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, calibrators, controls, or any other components typically associated with in vitro diagnostics.
In summary, the Piolax Hydrophilic Guidewire is an invasive medical device used for guiding catheters within the body, not a device used for performing tests on samples outside the body.

Intended Use / Indications for Use
The Piolax Hydrophilic Guidewire is a catheter guidewire, coated with a hydrophilic polymer in order to reduce frictional resistance in two phases between the wire and the blood vessel and between the wire and the inner surface of the catheter, thereby allowing the Guidewire to more easily reach the intended area. The Piolax Hydrophilic Guidewire is intended for vascular therapeutic and diagnostic applications, particularly for arterial and venous applications in the cardiac, cerebral, and abdominal regions.

Device Description
The Piolax Hydrophilic Guidewire is a tapered wire. composed of stainless steel or Ni-Ti alloy that is coated with a hydrophilic polymer. The hydrophilic polymer is composed of polyvinyl pyrrolidone and benzoyl peroxide. The Guidewire is provided with one of three differently shaped hydrophilic polymer-coated tips (i.e., straight, angled, J-shaped). The standard wire diameters are 0.58 mm, 0.72 mm, 0.79 mm, and 0.86 mm. The range for length of guidewires is 450 to 3,000 mm.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Piolax conducted tensile strength, torque strength, torqueability, tip flexibility, and coating adherence testing consistent with FDA's Coronary and Cerebrovasculature Guidewire Guidance (Jan. 1995). The test results demonstrate that the Piolax Hydrophilic Guidewire is substantially equivalent to the Terumo Radiofocus® Guidewire.
In addition, Piolax conducted the following biocompatibility tests: pyrogen rabbit extract test; hemolytic extract test; cytotoxicity test; sensitization test; intracutaneous reaction test; acute systemic toxicity test; blood compatibility test; and USP rabbit pyrogen test. All tests demonstrated that the Piolax Hydrophilic Guidewire is biocompatible.
Shelf-life testing on the Piolax Hydrophilic Guidewire demonstrates that the device has a shelf-life expiration date of two years.
Based on results of the above testing, Piolax concludes that the Piolax Hydrophilic Guidewire is as safe and as effective as Terumo's Radifocus® Guidewire.

The Piolax Hydrophilic Guidewire is contraindicated for use in coronary vessels.
Technological Characteristics:
The Piolax Hydrophilic Guidewire is composed of materials similar to that of the Terumo Radifocus® Guidewire. Both are composed of a stainless steel or similar alloy, with a urethane resin layer, and both have a hydrophilic polymer coating material. The Piolax Hydrophilic Guidewire differs in that its primary layer includes another resin (in addition to the urethane resin), that serves as a primer for the hydrophilic coating. Additionally, the composition of the hydrophilic coating differs. The diameters and lengths of the two wires are similar.
Performance Data: Piolax conducted tensile strength, torque strength, torqueability, tip flexibility, and coating adherence testing consistent with FDA's Coronary and Cerebrovasculature Guidewire Guidance (Jan. 1995). The test results demonstrate that the Piolax Hydrophilic Guidewire is substantially equivalent to the Terumo Radiofocus® Guidewire.
