You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's {1}------------------------------------------------ requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Tustin, California U.S.A Telephone: (714)247-8201 Contact Name: Ganesh Balachandar E-mail address: ganesh.balachander(@)microvention.com Date prepared: 15-April-2020 ### II DEVICE [807.92(a)(2)] | Name of Device: | Traxcess™ 14 SELECT Guidewire | |---------------------------|------------------------------------------------------------------------------------------------------------------------------| | Common or Usual Name: | Guidewire | | Classification Name: | Catheter Guidewire | | Product Code: | MOF, DQX | | Regulatory Class: | Class II | | Submission Type: | Special 510(k) | | Regulation Number: | 21 CFR 870.1330 | | Reviewing Product Branch: | Division of Neurosurgical, Neurointerventional, and<br>Neurodiagnostic Devices (Office of Product Evaluation and<br>Quality) | III PREDICATE DEVICE [807.92(a)(3)] Traxcess 14 SELECT Guidewire (K153053) ### IV DEVICE DESCRIPTION [807.92(a)(4)] The Traxcess™ 14 SELECT Guidewire is a coiled wire that is designed to fit inside a percutaneous catheter for the purpose of directing the catheter through a blood vessel. The core wire proximal coated section is 0.014" stainless steel wire, and the distal coated section is tapered nitinol wire, contained within a 0.012" outer diameter wire coil. The wire coil is 400 mm in length. The distal 30 mm coil section is constructed of platinum/nickel for maximum radiopacity, and the balance, 370mm of the coil is constructed of stainless steel. The distal 14 mm section of the guidewire is shapeable by the physician. {4}------------------------------------------------ The coil section of the guidewire and the distal stainless-steel section is coated with a hydrophilic coating, while the proximal stainless-steel section is coated with PTFE. The purpose of these surface coatings is to provide lubricity when the Traxcess™ 14 SELECT guidewire is passed through percutaneous catheters. A shaping mandrel, torque device, and insertion tool are included with the device. ## V INDICATIONS FOR USE [807.92(a)(5)] The Traxcess™ 14 SELECT Guidewire is indicated for general intravascular use, including the neuro and peripheral vasculature. The guidewire can be steered to facilitate the selective placement of diagnostic or therapeutic catheters. This device is not intended for use in coronary arteries. # VI COMPARISON OF TECHNOLOGICAL CHARACTERISTICS [807.92(a)(6)] The Traxcess™ 14 SELECT Guidewire has the following similarities to the predicate device, Traxcess™ 14 SELECT Guidewire (KT53053): - Have the same intended use 1. - 2. Use the same operating principle - 3 Incorporate the same basic guidewire design - 4. Incorporate the same guidewire construction material - റ് Are packaged and sterilized using the same materials and processes The change in the alternative PTFE coating on the proximal stainless-steel section of the guidewire does not change the indications for use of the Traxcess™ guidewires and is not a change to the fundamental scientific technology. The performance data below shows the device will perform as well as the previously marketed device. The Table 1 states the comparison between Traxcess™ 14 SELECT Guidewire (Predicate Device, K153053) and Traxcess™14 SELECT Guidewire (Subject Device). | Description | Predicate Device (Existing)<br>Traxcess™ 14 SELECT<br>Guidewire | Subject Device (Modified)<br>Traxcess™ 14 SELECT<br>Guidewire (K200547) | Rationale for<br>Differences (if<br>any) | |---------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------| | Indications for Use | The Traxcess™ 14 SELECT<br>Guidewire is intended for<br>general intravascular use,<br>including the neuro and<br>peripheral vasculature.
