Intended Use
The Glidewire is designed to direct a catheter to the desired anatomical location in the peripheral vasculature during diagnostic or interventional procedures. This device is not intended for neurovascular or coronary interventions.
Device Description
The Radifocus Glidewire is a guide wire which is designed to fit inside a percutaneous catheter for the purpose of directing a catheter through the blood vessel. It is provided sterile and is intended for single use only. It consists of a Nickel Titanium alloy core wire; a polyurethane coating (containing tungsten) and a hydrophilic polymer coating are applied to the entire wire. There are two shaft configurations: standard and stiff. There are two distal tip shapes: straight and angled, and two types of flexible part lengths of the tip: 3 and 5cm. The Radifocus Glidewire is packaged in a plastic holder that is contained within an individual package. A guide wire inserter is included within the individual package to assist with the insertion of the guide wire into a catheter.
More Information

No
The device description and performance studies focus on the physical properties and mechanical performance of a guide wire, with no mention of software, algorithms, or data processing that would indicate AI/ML.

No
The device is described as a guide wire designed to direct a catheter, which is an accessory used during surgical/diagnostic procedures, not a device that directly treats a condition.

No

The Glidewire is designed to direct a catheter, which can be used for diagnostic procedures, but the glidewire itself does not perform any diagnostic function.

No

The device description clearly states it is a physical guide wire made of Nickel Titanium alloy with coatings, and includes a guide wire inserter. This is a hardware device, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the device is designed to "direct a catheter to the desired anatomical location in the peripheral vasculature during diagnostic or interventional procedures." This describes a device used within the body for procedural guidance, not a device used to test samples outside the body to diagnose conditions.
  • Device Description: The description details a guide wire used to navigate blood vessels, which is consistent with an interventional or diagnostic tool used directly on a patient.
  • Lack of IVD characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any other components typically associated with in vitro diagnostics.

Therefore, the Radifocus Glidewire is a medical device used for guiding catheters within the body, not an in vitro diagnostic device.

N/A

Intended Use / Indications for Use

The Glidewire is designed to direct a catheter to the desired anatomical location in the peripheral vasculature during diagnostic or interventional procedures. This device is not intended for neurovascular or coronary interventions.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Testing was conducted to ensure the performance of the Radifocus Glidewire throughout the labeled shelf life, verify conformity to the applicable parts of ISO standard and demonstrate substantial equivalence to the predicate device. With the exception of the Radiodetectability1 test, the following performance tests were performed on non-aged and accelerated aged Radifocus Glidewire samples. All samples tested met the standard applicable to each test, and no new issues of safety and effectiveness were raised with the testing performed.
Tests performed include:

  • Surface (Section 4.3 of ISO 11070:2014)
  • Radiodetectability (Section 4.5 of ISO 11070:2014, ASTM F640-12)
  • Fracture Test (Section 8.4 of ISO 11070:2014)
  • Flexing Test (Section 8.5 of ISO 11070:2014)
  • Peak Tensile Force of Guidewire (Section 8.6 of ISO 11070:2014, 3.a of Coronary and Cerebrovascular Guidewire Guidance, January 1995)
  • Torque Strength (3.b of Coronary and Cerebrovascular Guidewire Guidance, January 1995, In-house Standard)
  • Torqueability (3.c of Coronary and Cerebrovascular Guidewire Guidance, January 1995, In-house Standard)
  • Tip Flexibility (3.d of Coronary and Cerebrovascular Guidewire Guidance, January 1995, In-house Standard)
  • Sliding Resistance/Coating Integrity (Product Appearance) (3.e of Coronary and Cerebrovascular Guidewire Guidance, January 1995, In-house Standard)
  • Particulate Evaluation (VIII.A.13 of Class II Special Controls Guidance Document for Certain Percutaneous Transluminal Coronary Angioplasty (PTCA) Catheters, September 8, 2010, USP, In-house Standard)
  • Product Dimension (In-house Standard)

Performance testing demonstrated that the Radifocus Glidewire conformed to the recognized consensus ISO standard and FDA guidance documents, is substantially equivalent to the predicate device, and is acceptable for clinical use throughout its shelf life.
