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 {1}------------------------------------------------ statutes and regulations administered by other Federal agencies. You must comply with all the Act's 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 (QS) 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.

The distal core wire is tapered at the distal tip and is contained within platinum/nickel coil. The platinum/nickel coil is 6 cm in length. The distal 1.4 cm of the guidewire is shapeable by the physician. Traxcess™ 7 Mini Guidewire distal and proximal sections are coated with hydrophilic coating. {4}------------------------------------------------ There is no PTFE coating. The purpose of the hydrophilic coating is to provide lubricity when the MicroVention guidewire is passed through microcatheters. Shaping mandrels, insertion tool, and torque device are also included with the device. # V INDICATIONS FOR USE [807.92(a)(5)] Traxcess™ 7 Mini 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 indicated for use in coronary arteries. ## VI COMPARISON OF TECHNOLOGICAL CHARACTERISTICS [807.92(a)(6)] Traxcess™ 7 Mini Guidewire has the following similarities to the predicate device, Traxcess™ 7 Mini Guidewire (K161803): - Have the same intended use ● - Use the same operating principle - Incorporate the same basic guidewire design ● - Incorporate the same guidewire construction material ● - Are packaged and sterilized using the same materials and processes ● The change in core wire taper diameter profile for the Traxcess™ 7 Mini guidewire for better support and compatibility with microcatheters does not change the indications for use of the Traxcess™ 7 Mini Guidewire 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. {5}------------------------------------------------ The Table 1 states the comparison between Traxcess™ 7 Mini Guidewire (Predicate Device, K161803) and Traxcess™ 7 Mini Guidewire (Subject Device). | Description | Reference Device (Existing) | Predicate Device (Existing) | Subject Device (Modified) | Rationale for Difference (if any) | |-------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------| | | Traxcess™ 14 SELECT<br>Guidewire (K200547) | Traxcess™ 7 Mini<br>Guidewire (K161803) | Traxcess™ 7 Mini<br>Guidewire | | | Indications for Use | Traxcess™ 14 SELECT<br>Guidewire is indicated for<br>general intravascular use,<br>including the neuro and<br>peripheral vasculature.
