Intended Use

The Microcatheter is indicated for use in the selective placement of devices and/or fluids, such as contrast media, into the peripheral, coronary, and neuro vasculature during diagnostic and/or therapeutic procedures.

Device Story

Trevo Trak 21 Microcatheter is a single-lumen, braided shaft, variable stiffness catheter designed for navigation within peripheral, coronary, and neuro vasculature. It features a hydrophilic coating to reduce friction and radiopaque markers for fluoroscopic visualization. The device is advanced over a guide wire to a target location to facilitate the delivery of therapeutic devices or contrast media. It is intended for use by physicians in clinical settings. The device is supplied sterile for single use. The primary clinical benefit is enabling precise, minimally invasive access to complex vascular anatomy for diagnostic or therapeutic interventions.

Clinical Evidence

No clinical or animal studies were conducted. Substantial equivalence is supported by non-clinical bench testing, including simulated use/compatibility, particulate characterization, coating integrity, and track force testing. All tests met established acceptance criteria.

Technological Characteristics

Single-lumen, braided stainless steel shaft, variable stiffness. Materials: PTFE inner layer, polyolefin strain relief, polyurethane hub, platinum/iridium marker bands, acrylic adhesive. Hydrophilic coating. Dimensions: 2.4F/2.0F outer diameter, 0.021" inner diameter, 162 cm length. Sterilization: 100% Ethylene Oxide (SAL 10^-6).

Indications for Use

Indicated for selective placement of devices and/or fluids (e.g., contrast media) into peripheral, coronary, and neuro vasculature during diagnostic or therapeutic procedures. No specific age or gender restrictions.

Regulatory Classification

Identification

{6}------------------------------------------------

The differences between the devices do not raise new questions of safety and effectiveness.

#### Risk Assessment

A risk assessment of the Trevo Trak 21 Microcatheter has been conducted in accordance with EN ISO 14971. Stryker Neurovascular has determined that the labeling changes to the Trevo Trak 21 Microcatheter raise no new questions of safety and effectiveness. The results of testing demonstrate that the Trevo Trak 21 Microcatheter with the modified labeling is substantially equivalent to the legally marketed Predicate device.

# Testing Summary

#### Performance Data – Bench Testing

Stryker Neurovascular performed the following non-clinical bench testing to assess the compatibility of the Trevo Trak 21 Microcatheter with 0.046 inch inner diameter (ID) guide catheters. The bench testing is summarized in Table 2 below.

{7}------------------------------------------------

| Test | Test Method Summary | Conclusions |
|---------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------|
| Simulated<br>Use/Compatibility | User will assess Trevo Trak™ 21 Microcatheter<br>with a worst case compatible guide catheter in the<br>in vitro simulated use model. | Simulated Use<br>testing met<br>acceptance criteria. |
| Particulate<br>Characterization | Use light obscuration particle counting to<br>measure the total number of particulates<br>generated during simulated use. | Particulate<br>generation was<br>acceptable and<br>comparable to<br>the predicate<br>device. |
| Coating Integrity | Use visual inspection to identify the location,<br>size, and number of occurrences of anomalies on<br>the coated surface of the Trevo Trak™ 21<br>Microcatheter before<br>and after simulated use. | Coating integrity<br>was acceptable both<br>before and after<br>simulated use. |
| Track Force Testing | Use a Track Tester Model to measure the Trevo<br>Trak™ 21 Microcatheter track force through a<br>guide catheter during simulated use. | Track Testing<br>results met<br>acceptance criteria. |

# Sterilization

The sterilization evaluation previously conducted for the Trevo Trak 21 Microcatheter was used to support the subject device and can be found in K192122. The Trevo Trak 21 Microcatheter is sterilized with 100% Ethylene Oxide. The Trevo Trak 21 Microcatheter and accessory are provided sterile. A sterility assurance level (SAL) of 106 has been demonstrated. The Trevo Trak 21 Microcatheter and accessory meet EO residuals per EN ISO 10993-7 for a limited contact delivery system – externally communicating. The Trevo Trak 21 Microcatheter and accessory are for single use only.

#### Biocompatibility

The biocompatibility testing previously conducted for the Trevo Trak 21 Microcatheter was used to support the subject device and can be found in K192122. The results of biocompatibility testing and biological safety evaluation of the Trevo Trak 21 Microcatheter demonstrate that the device meets the biological safety requirements per EN ISO 10993-1, "Biological evaluation of Medical Devices – Part 1: Evaluation and Testing within a Risk Management Process" for an externally communicating medical device with circulating blood contact for less than 24 hours. Therefore, the Trevo Trak 21 Microcatheter, accessory, and primary packaging are considered biocompatible for their intended use.

#### Conclusion

Stryker Neurovascular has demonstrated the Trevo Trak 21 Microcatheter is substantially equivalent to the Predicate device (K192122) based on same intended use / indications for use, same materials, same fundamental design, and the same operating principles. The conclusions drawn from the risk assessment and the bench testing results summarized above demonstrate that the benefits of the device outweigh any residual risks when used in accordance with the device Instructions for Use. Stryker Neurovascular has demonstrated that the Trevo Trak 21 Microcatheter is substantially equivalent to the legally marketed Predicate device.
