Device Facts

• Record ID: K113454
• Device Name: 14 WIRE STANDARD, 14 WIRE LS
• Applicant: Micro Therapeutics, Inc.
• Product Code: DQX · Cardiovascular
• Decision Date: Feb 24, 2012
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 870.1330
• Device Class: Class 2

Intended Use

The 14 Wire Hydrophilic Guidewire is indicated for general intravascular use to aid in the selective the optime of catheters in the peripheral and cerebral vasculature during diagnostic and/or therapeutic procedures. The device is not intended for use in the coronary arteries. The Guidewire Torque Device is intended to facilitate guidewire manipulation during interventional procedures. The Guidewire Introducer is intended to facilitate guidewire insertion into a catheter hub or through a hemostasis valve.

Device Story

The 14 Wire is a stainless steel guidewire with a radiopaque distal segment and a hydrophilic coating. It is used by physicians in clinical settings to assist in the selective placement of catheters within the peripheral and cerebral vasculature. The device includes a torque device for manual manipulation and an introducer to aid insertion into catheter hubs or hemostasis valves. By providing a trackable, lubricious path, the guidewire facilitates the navigation of diagnostic or therapeutic catheters to target sites, potentially improving procedural success and reducing vessel trauma. It is a manual, non-powered device.

Clinical Evidence

Bench testing only. Performance data included visual and dimensional inspection, tip flexibility, buckling force, torque response, shapeability/retention, flexing, coating adherence/lubricity, navigation, kink resistance, tensile/fracture strength, and corrosion resistance. Biocompatibility, shelf-life, bioburden, pyrogen, EtO residuals, and sterility testing were also performed.

Technological Characteristics

Stainless steel guidewire with radiopaque distal segment and hydrophilic coating. Includes torque device and introducer. Mechanical device; no energy source. Sterilized via EtO. Performance specifications include tip flexibility, torque response, and tensile strength.

Indications for Use

Indicated for patients requiring selective catheter placement in peripheral and cerebral vasculature during diagnostic or therapeutic procedures. Not for use in coronary arteries.

Regulatory Classification

Identification

A catheter guide wire is a coiled wire that is designed to fit inside a percutaneous catheter for the purpose of directing the catheter through a blood vessel.

Special Controls

*Classification.* Class II (special controls). The device, when it is a torque device that is manually operated, non-patient contacting, and intended to manipulate non-cerebral vascular guide wires, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.
