Intended Use

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.

Device Story

Traxcess™ 14 SELECT Guidewire is a steerable, coiled wire used to navigate percutaneous catheters through blood vessels. Device consists of 0.014" proximal stainless steel core, tapered nitinol distal core, and 0.012" outer diameter coil. Distal 30 mm coil is platinum/nickel for radiopacity; remaining 370 mm is stainless steel. Distal 14 mm is shapeable by physician. Proximal section has PTFE coating; distal section and distal stainless-steel portion have hydrophilic coating for lubricity. Used in clinical settings (neuro/peripheral procedures) by physicians to guide catheters. Includes shaping mandrel, torque device, and insertion tool. Benefits include improved catheter placement accuracy and navigation through complex vasculature.

Clinical Evidence

Bench testing only. Testing included physical attributes (dimensions), surface contamination, corrosion resistance, simulated use (tracking/introduction), coating adherence, fracture resistance, and particulate testing. Biocompatibility testing performed per ISO 10993 standards, including cytotoxicity, sensitization, irritation, acute systemic toxicity, pyrogenicity, and comprehensive hemocompatibility (hemolysis, coagulation, complement activation, thrombus formation, thrombogenicity). All tests met acceptance criteria.

Technological Characteristics

Coiled guidewire; 0.014" proximal stainless steel core; tapered nitinol distal core; 0.012" OD coil. Platinum/nickel distal coil (30mm) for radiopacity; stainless steel proximal coil (370mm). Hydrophilic coating (distal/stainless section); PTFE coating (proximal section). Sterilized via ethylene oxide. Manual operation; no software or electronics.

Indications for Use

Indicated for patients requiring general intravascular procedures, including neuro and peripheral vasculature, to facilitate selective placement of diagnostic or therapeutic catheters. Not for use in coronary arteries.

Dear Ganesh Balachandar:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). 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.

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).
