Intended Use

This guide wire is intended to be used in the neuro vasculature to facilitate the placement and exchange of therapeutic devices such as cerebral catheters during intravascular therapy. This guide wire is intended for use only in the neuro vasculature.

Device Story

ASAHI CHIKAI series are steerable neurovascular guide wires; used by physicians in clinical settings to navigate neurovasculature; facilitate placement/exchange of therapeutic devices like cerebral catheters. Device consists of stainless steel core wire with inner/outer coil assembly; distal diameters range 0.008-0.018 inches; lengths 200-300cm. Hydrophilic coating reduces friction. Physician manually manipulates proximal end to steer distal tip through vasculature under imaging guidance. Output is mechanical support and track for catheter delivery. Benefits include improved access to distal neurovascular sites for interventional procedures.

Clinical Evidence

Bench testing only. No clinical data presented. Performance evaluated via simulated use models, tensile strength, torque strength, torqueability, tip flexibility, coating adherence, and particulate characterization. All test articles met established acceptance criteria based on predicate device performance and manufacturer specifications.

Technological Characteristics

Stainless steel core wire; inner and outer coil assembly; hydrophilic coating. Diameters: 0.008", 0.014", 0.018". Lengths: 200cm, 300cm. Tip shapes: straight, round curve, angled 90°. Sterilization: ETO. Biocompatibility per ISO 10993.

Indications for Use

Indicated for use in the neuro vasculature to facilitate placement and exchange of therapeutic devices (e.g., cerebral catheters) during intravascular therapy. No specific age or gender restrictions provided.

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.

Table 1 Comparison of ASAHI CHIKAI series to the predicate devices.

The materials used in the manufacture of the ASAHI CHIKAI series tapered core wire, coils and coating materials, and the manufacturing processes are the same as those used for ASAHI's Prowater and Marker Wire PTCA Guide Wires (K022762) and ASAHI PTCA Guide Wire Fielder (K052022), which were subject to full biocompatibility testing in accordance with ISO 10993.

#### Non-clinical Performance Data:

The safety and effectiveness of the ASAHI CHIKAI series line extension was evaluated in bench testing that followed the recommendations in the FDA guidance document: Coronary and Cerebrovascular Guidewire Guidance. Table 2 provides a summary of the bench test methods, results and conclusions. Acceptance criteria for each of the tests were determined by prior comparative testing with predicate devices, ASAHI's established guide wire specifications, and clinical experience.

| Test | Test Method Summary | Results/Conclusions |
|--------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Tensile<br>Strength | To determine maximum allowable tensile<br>load between connections, guide wire is<br>fixed in the Tensile Testing Machine and<br>pulled until failure. | All test articles met established tensile<br>strength acceptance criteria. Acceptance<br>criteria determined by evaluation of<br>predicate devices and ASAHI's<br>established tensile strength specifications. |
| Torque Strength | To determine torque strength, distal end is<br>inserted & advanced through simulated<br>model. Distal tip is held stationary while<br>proximal end is rotated until failure. | All test articles met the acceptance<br>criteria. Acceptance criteria determined<br>by evaluation of predicate devices and<br>ASAHI's established torque strength<br>specifications. |
| Torqueability | To determine torque response, guidewire is<br>inserted through catheter & into Rotational<br>Response model. Proximal end is rotated<br>and the torque response at distal end is<br>measured. | All test articles met the acceptance<br>criteria. Torque response is similar or<br>better than predicate. |
| Tip Flexibility | To determine flexibility of the distal end, the<br>force to deflect the guide wire is measured<br>by a force analyzer attached to a load cell. | All test articles met established Tip<br>Flexibility acceptance criteria.<br>Acceptance criteria determined by<br>evaluation of predicate devices and<br>ASAHI's established Tip Flexibility<br>specifications. |
| Coating<br>Adherence | Integrity of coated outer coil & core wire is<br>determined before, and after, pretreatment<br>and manipulation in excess of that expected<br>in clinical use. | Test results confirmed that the integrity of<br>the coating was maintained during<br>simulated clinical use in all test articles. |
| Coating Integrity<br>& Particulate<br>Characterization | Coating integrity and particulates were<br>evaluated. The test samples were advanced<br>through a microcatheter to the target<br>location, retracted and the coating inspected<br>under magnification. All particulate matter<br>generated during insertion/retraction of the<br>guidewire was counted & classified by their<br>particle sizes. | This testing characterized the coating<br>integrity and particulate generation during<br>simulated use. |
| Catheter<br>Compatibility | Catheter compatibility is evaluated by<br>measuring the force to withdraw the guide<br>wire that has been inserted through the test<br>catheter. | All test articles met the acceptance<br>criteria. Resistance to catheter<br>withdrawal is similar or better than<br>predicate. |
| Bench<br>(Simulated)<br>Testing | To simulate clinical use, guidewire is<br>inserted through guide catheter placed in<br>simulated model and advanced to target area.<br>Interventional catheter is inserted over<br>guidewire & advanced to target cerebral<br>artery multiple times. | Test results on all test articles confirmed<br>guide wire performance. Guidewire<br>reached target area and interventional<br>catheter was successfully advanced over<br>guidewire to target site. |

Table 2 ASAHI CHIKAI series Bench Test Summary

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

All neurovascular guide wires in the ASAHI CHIKAI series met the acceptance criteria for each of the bench tests.

## Conclusion

Based on the similar indication, design and materials, and the results of the bench testing, the ASAHI CHIKAI series line extension is considered substantially equivalent to the predicate devices listed above.
