Intended Use

ASAHI PTCA Guide Wires: ASAHI PTCA Guide Wires are intended to facilitate the placement of balloon dilation catheters during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA). The ASAHI PTCA Guide Wires are not to be used in the neurovasculature. ASAHI Peripheral Guide Wires: ASAHI Peripheral Guide Wires are intended to facilitate the placement and exchange of diagnostic and therapeutic devices during intravascular procedures. This device is intended for peripheral vascular use only. ASAHI Guide Wire Extension: The ASAHI Guide Wire Extension accessory is intended for extension of the working length of an already introduced guide wire when exchanging over-the-wire interventional devices during an angioplasty procedure.

Device Story

Steerable guide wires; core wire with coil assembly; radiopaque distal tip for visibility. Used in PTCA, PTA, and peripheral vascular procedures to facilitate placement/exchange of catheters and interventional devices. Operated by physicians in clinical settings. Modification involves alternate PTFE coating manufactured without PFOA. Device functions as a mechanical guide; no electronic or software components. Benefits include maintained clinical performance and safety profile while eliminating PFOA in manufacturing.

Clinical Evidence

Bench testing only. Evaluated coating adherence, coating integrity, and particulate generation using simulated clinical use models. Biocompatibility testing performed per ISO 10993 (cytotoxicity, irritation, sensitization, systemic toxicity, pyrogenicity, hemocompatibility). Results confirmed the modified coating maintains integrity, generates no excessive particulates, and is biocompatible, performing similarly to predicate devices.

Technological Characteristics

Steerable guide wire with core wire and coil assembly. Radiopaque distal tip. Proximal portion coated with PTFE (alternate material without PFOA). Sterilization method unchanged. Mechanical device; no energy source or software.

Indications for Use

Indicated for patients undergoing percutaneous transluminal coronary angioplasty (PTCA) or percutaneous transluminal angioplasty (PTA) (PTCA wires); or patients undergoing intravascular procedures requiring placement/exchange of diagnostic/therapeutic devices (Peripheral wires). Contraindicated for neurovasculature use (PTCA wires).

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.

# INTENDED USE/INDICATIONS FOR USE

The intended use of these wires are unchanged:

ASAHI PTCA Guide Wires:

ASAHI PTCA Guide Wires are intended to facilitate the placement of balloon dilation catheters during percutaneous translyminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA). The ASAHI PTCA Guide Wires are not to be used in the neurovasculature.

# ASAHI Peripheral Guide Wires:

ASAHI Peripheral Guide Wires are intended to facilitate the placement and exchange of diagnostic and therapeutic devices during intravascular procedures. This device is intended for peripheral vascular use only.

# ASAHI Guide Wire Extension

The ASAHI Guide Wire Extension accessory is intended for extension of the working length of an already introduced guide wire when exchanging over-the-wire interventional devices during an angioplasty procedure.

# DEVICE DESCRIPTION:

This modification details a change relating to the removal of perfluorooctanoic acid (PFOA) used by suppliers in the manufacture of PTFE (polytetrafluoroethylene) coating used on the ASAHI family of guidewires including ASAHI PTCA guide wires and ASAHI peripheral guidewires. All of these wires are steerable guide wires, constructed with a core wire with coil assembly. The distal ends of the guide wires have a radiopaque tip to achieve visibility. Various coatings are applied to the distal and proximal portions of the guidewires.

This submission covers the addition of an alternate type of PTFE coating material. The designs and performance of the guidewires are unchanged.

#### COMPARISON WITH PREDICATE DEVICES:

The technological characteristics of the subject guide wires are substantially equivalent to those of the predicate guidewires. The differences between the devices relates to the guide wire proximal coating. The guide wire design and indications remain unchanged.

Comparisons of the revised ASAHI guide wires to the predicate devices show that the technological characteristics of the Subject device such as the product performance, intended use/indications, components, materials, sterilization method, shelf life, manufacturing process, and operating principle are identical to the currently marketed predicate devices. The only difference is in the PTFE coating applied to the proximal portion of the device. The new PTFE is manufactured by a supplier without the use of PFOA.

| Test | Test Method Summary | Results/Conclusions |
|-----------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Coating<br>Adherence | Integrity of the coated core wire is<br>determined before and after pretreatment<br>and manipulation in excess of that<br>expected in clinical use. | Test results confirmed that the coating<br>adhesion was maintained during<br>simulated clinical use in all test articles. |
| Coating<br>Integrity &<br>Particulate<br>Characterization | Coating integrity and particulate<br>generation were evaluated. The test<br>samples were advanced through a<br>clinically relevant simulated use model to<br>the target location, retracted and the<br>coating inspected under magnification.<br>All particulate matter generated during<br>insertion/retraction of the guidewire was<br>characterized. | This testing characterized the coating<br>integrity and particulate generation<br>during simulated use. The test results<br>confirmed that the coating integrity was<br>maintained during simulated clinical use<br>of the test articles. |

The in vitro bench tests demonstrated that the devices with the modified coating met all acceptance criteria and performed similarly to the predicate devices. Performance data demonstrate that the device functions as intended, and has a safety and effectiveness profile that is similar to the predicate devices.

# CONCLUSION:

The ASAHI guidewires with the alternate coating have the identical intended use and the same technological characteristics such as components, design, sterilization method, shelf life and operating principles as the predicate devices. Data demonstrate that the device performance is unchanged.

Therefore, the ASAHI guidewires are substantially equivalent to the predicate devices.
