The Glidewire® GT 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.
The Glidewire® GT is a guide wire which is designed to direct a catheter to the desired anatomical location in the peripheral vasculature during diagnostic or interventional procedures. It is provided sterile and is intended for single use only. The Glidewire® GT consists of a core wire of a Nickel Titanium superelastic alloy and has a flexible radiopaque gold coil around the distal tip of the core wire. The Glidewire® GT is offered with two distal tip types: Shapeable and Preshaped. The wire distal segment comes in angled or straight configurations. Physicians choose the guide wire types depending upon their personal preference and the type of interventional procedure being performed. Other considerations may include: anatomy, difficulty of access, and the interventional device used for procedure. The device is packaged in a plastic holder that is contained within an individual package. A guide wire inserter, torque device and mandrel (Shapeable type only) are contained within the individual package to assist with the manipulation of the guide wire. Following the guide wire insertion, the guide wire inserter is removed from the proximal portion of guide wire.
The provided document is a 510(k) summary for the Glidewire GT and describes non-clinical performance and biocompatibility testing to demonstrate substantial equivalence to a predicate device. It does not contain information about a study proving the device meets an acceptance criterion for an AI/ML device.
Here's an analysis based on the structure of the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The document describes several performance tests. It states that "All samples tested met the applicable acceptance criteria, and no new issues of safety and effectiveness were raised by the testing performed." However, it does not explicitly list the specific quantitative acceptance criteria alongside the reported performance for each test. Instead, it refers to ISO standards, FDA guidance documents, and in-house standards.
General Summary of Performance Testing:
| Test Item | Reference Standard/Guidance | Reported Performance |
|---|---|---|
| Surface | Sec. 4.3 of ISO 11070: 2014 | Met applicable acceptance criteria |
| Radiodetectability | Sec. 4.5 of ISO 11070: 2014, ASTM F640-12 | Met applicable acceptance criteria |
| Fracture Test | Sec. 8.4 of ISO 11070: 2014 | Met applicable acceptance criteria |
| Flexing Test | Sec. 8.5 of ISO 11070: 2014 | Met applicable acceptance criteria |
| Peak Tensile Force of guidewire (ISO Standard) | Sec. 8.6 of ISO 11070: 2014 | Met applicable acceptance criteria |
| Peak Tensile Force of guidewire (FDA Guidance) | 3.a of FDA Guidance, In-house Standard | Met applicable acceptance criteria |
| Torque strength | 3.b of FDA Guidance, In-house Standard | Met applicable acceptance criteria |
| Torqueability | 3.c of FDA Guidance, In-house Standard | Met applicable acceptance criteria |
| Tip flexibility | 3.d of FDA Guidance, In-house Standard | Met applicable acceptance criteria |
| Sliding resistance/Coating integrity (Product appearance) | 3.e of FDA Guidance, In-house Standard | Met applicable acceptance criteria |
| Particulate evaluation | VIII.A.13 of FDA Guidance, USP <788>, In-house Standard | Met applicable acceptance criteria |
| Product dimension | In-house Standard | Met applicable acceptance criteria |
| Shaping test | In-house Standard | Met applicable acceptance criteria |
Biocompatibility: The device is classified as Externally Communicating Devices, Circulating blood, Limited Contact (<24 hrs). It's deemed biocompatible based on substantial equivalence to predicate devices with the same classification, intended use, body contact, and contact duration, and demonstrated histories of safe and effective clinical use.
Sterilization: Validated in accordance with ISO 11135: 2014 to provide a Sterility Assurance Level (SAL) of 10-6.
2. Sample Size Used for the Test Set and Data Provenance
The document states, "All samples tested met the applicable acceptance criteria," indicating that a test set was used for each performance test. However, the specific sample sizes for each test are not provided.
Data Provenance: The data comes from non-clinical (bench) performance testing and biocompatibility evaluation based on predicate devices. There is no mention of country of origin as it's not clinical data, nor is it retrospective or prospective in the sense of patient data.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not applicable as the document describes a 510(k) submission for a medical device (guide wire) based on non-clinical performance and biocompatibility. It does not involve AI/ML, image analysis, or expert-established ground truth on a test set in the context of an AI/ML device. The "ground truth" for the performance tests would be the established scientific and engineering principles and standards against which the functional performance of the guide wire is measured.
4. Adjudication Method for the Test Set
This information is not applicable for the same reasons as #3. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies or expert review of data/images to establish ground truth for AI/ML performance evaluation.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done
No, a Multi Reader Multi Case (MRMC) comparative effectiveness study was not done. This type of study is relevant for evaluating the impact of AI on human reader performance, which is not described in this document.
6. If a Standalone (i.e., Algorithm Only Without Human-in-the-Loop Performance) Was Done
No, a standalone (algorithm only) performance study was not done. This document pertains to a physical medical device (a guide wire), not an AI algorithm.
7. The Type of Ground Truth Used
The "ground truth" for the non-clinical performance and biocompatibility studies is derived from:
- Recognized consensus ISO standards (e.g., ISO 11070: 2014, ISO 11135: 2014, ISO 10993-1: 2009)
- FDA guidance documents (e.g., Coronary and Cerebrovascular Guidewire Guidance, Class II Special Controls Guidance Document for Certain PTCA Catheters)
- In-house standards of Terumo Medical Corporation
- Biocompatibility data and clinical histories of legally marketed predicate devices
8. The Sample Size for the Training Set
This information is not applicable as the document describes a physical medical device (guide wire) and not an AI/ML device that requires a training set.
9. How the Ground Truth for the Training Set Was Established
This information is not applicable for the same reasons as #8.

recognized consensus ISO standards, FDA guidance documents or in-house standards, is substantially equivalent to the predicate device for its shelf life.
Biocompatibility
In accordance with ISO 10993-1: 2009, Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process, the Glidewire® GT is classified as an Externally Communicating Devices, Circulating blood, Limited Contact (<24 hrs). This is the same classification as the predicate Terumo Radifocus Guide Wire (K863138) which is intended for vascular use.
All the blood contacting materials from the subject device are the same as the predicate Terumo Radifocus Guide Wire (K863138) and the Radifocus Glidewire (K152740) which are intended for vascular use. The subject and predicate devices have the same intended use, body contact, and contact duration classification, based on ISO 10993-1: 2009. Additionally, the predicate product lines have a demonstrated histories of safe and effective use in the clinical setting. Therefore, Terumo concludes that the Glidewire® GT is biocompatible for its intended use based on biocompatibility testing leveraged from the predicate device.
Sterilization
The device was adopted into an existing sterilization cycle that was validated in accordance with ISO 11135: 2014, Sterilization of health-care products - Ethylene Oxide - Requirements for development, validation and routine control of a sterilization process for medical devices, to provide a Sterility Assurance Level (SAL) of 10-6.
Risk Analysis
A Product Risk Analysis was conducted in accordance with ISO 14971: 2007, Medical devices- Application of risk management to medical devices, and no new risks were identified.
