## E. DEVICE DESCRIPTION (807.92(a)(4))

#### Principle of Operation Technology

The Glidewire® GT is operated by manual process.

#### Design/Construction

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.

{5}------------------------------------------------

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.

#### Specifications

The specifications for the Glidewire® GT are provided in the table below.

| Part | Specification |

## H. NON CLINICAL TESTS (807.92(b)(1))

#### Performance

Performance testing was conducted to evaluate the performance of the Glidewire® GT throughout the labeled shelf life, verify conformity to applicable standards and demonstrate substantial equivalence to the predicate devices. With the exception of the Radiodetectability1 test, the following performance tests were performed on nonaged and accelerated-aged Glidewire® GT samples. All samples tested met the applicable acceptance criteria, and no new issues of safety and effectiveness were raised by the testing performed.

¹ Only baseline testing was performed since no change in the radiopacity of the gold markers is anticipated with aging.

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.
