#### Device Description

The Inno-Pathwire is a steerable guidewire available in a diameter of 0.014" (0.36 mm) and an effective length of 190 cm. The distal tip is shapeable. Before use, the tip can be shaped "J". The wire construction includes a stainless steel proximal shaft and a distal super-elastic nitinol shaft for flexibility and performance. The two shafts are connected by a super-elastic nitinol hypotube. The distal shaft is soldered with the tip coil or the tip coil and proximal coil both. For IW-14-190-EXS model, the distal shaft is soldered to the tip coil only but for IW-14-190-STS and IW-14-190-MDS, their distal shafts are soldered to the tip coil and proximal coil both. The tip coil is visible under Xray to assist the physician with the movement of the guidewire. The distal segment of the guidewire, up to the hypotube, is coated with hydrophilic coating to reduce friction for improved guidewire movement within the catheter and arteries. The proximal end of the guidewire is coated with PTFE coating which reduces friction of the wire within a catheter.

The guidewire is packaged in a plastic dispenser that is contained within an individual package. A Torquer is included which connects to the proximal end of the guidewire for twisting and controlling the guidewire. The guidewires are packaged within a cardboard box which contains five individual guidewires.

#### Intended Use

The Inno-Pathwire is intended to facilitate the placement of balloon dilatation catheters during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA).

#### Principle of Operation

The Inno-Pathwire is operated manually or by a manual process.

#### Substantial Equivalence

The Inno-Pathwire was found to be substantially equivalent to the HI-TORQUE BALANCE MIDDLEWEIGHT Guide Wires, Premarket Notification K152709. A comparison of the technological characteristics is summarized on the table below:

## Comparison of the Inno-Pathwire and Predicate Device

The Inno-Pathwire is substantially equivalent to the HI-TORQUE BALANCE MIDDLEWEIGHT Guide Wire in technology / principal of operation is similar in the material and design. The main differences between the Inno-Pathwire device and the predicate device are the tip coil material and the hydrophilic coating material. These differences do not affect the intended use, safety or effectiveness of the Inno-Pathwire. Performance (bench) testing and biocompatibility testing were performed to demonstrate that the proposed device performs as intended and does not raise new questions of safety or efficacy compared to the predicate devices.

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

#### Non-Clinical Performance Testing

Performance testing has been conducted in accordance with FDA guidance document Coronary and Cerebrovascular Guidewire Guidance, January 1995; Coronary, Peripheral, and Neurovascular Guidewire-Performance Tests and Recommended Labeling, Draft Guidance for Industry and Food and Drug Administration Staff, June 15, 2018; ISO 11070:2014, Sterile Single-use Intravascular Introducers, Dilators And Guidewires. The results of the following performance tests have demonstrated substantial equivalence to the predicate device.

- Dimensional Verification and Visual Inspection ●
- Torque Strength ●
- Coating Adherence/Integrity ●
- Lubricity ●
- Kink Resistance ●
- Radiopacity ●

#### Biocompatibility Testing

- Tensile Strength/Tip Pull ●
- Torqueability ●
- Particulate Evaluation ●
- Resistance to corrosion ●
- Tip Flexibility ●

Biocompatibility testing was performed to ensure the material safety in accordance with the tests recommended in the International Standard ISO 10993-1. "Biological Evaluation of Medical Devices Part-I: Evaluation and testing within a risk management process." The Inno-Pathwire is classified as an Externally Communicating Device, Circulating Blood, Limited Contact (≤24h).

The following biocompatibility testing, performed in accordance with ISO-10993, has been performed on the Inno-Pathwire:

| • Cytotoxicity | ISO 10993-5 |
|-------------------------------------------|------------------------|
| • Irritation and Skin Sensitization | ISO 10993-10 |
| • Acute Systemic Toxicity | ISO 10993-11 |
| • Pyrogenicity | ISO 10993-11 |
| • SC5b-9 Complement Activation | ISO 10993-4 |
| • Unactivated Partial Thromboplastin Time | ISO 10993-4 |
| • Rabbit Blood Hemolysis | ASTM F756 /ISO 10993-4 |
| • Hemocompatibility | ISO 10993-4 |
| • Thrombogenicity | ISO 10993-4 |

The results obtained from the biological evaluation indicate that the products do not pose any safety risks associated with its introduction into the body and that materials selected for manufacture of these products are appropriate for the intended use.

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

#### Sterilization

Sterilization conditions have been validated in accordance with ISO 11135, Sterilization of health care products - Ethylene oxide - Requirements for development, validation and routine control of a sterilization process for medical devices. The device is sterility Assurance Level (SAL) of 10 °. Residual ethylene oxide (EO) and ethylene chlorohydrin (ECH) will meet requirements for limited exposure devices (contact up to 24 hours) prior to use based on ISO 10993-7, Biological Evaluation of medical devices- Part 7: Ethylene Oxide Sterilization residuals.

### Pyrogenicity

The Inno-Pathwire has been evaluated for non-endotoxin related factors. The rabbit pyrogen test was performed as described in ANSI/AAMI/ISO 10993-11. The results concluded that the Inno-Pathwire does not elicit a material mediated pyrogenic response. As a requirement for product release, finished product pyrogen testing is conducted on each manufacturing lot for commercial distribution as a requirement for product release. The test method used is the gel clot method for Bacterial Endotoxin Testing.

#### Conclusion

The Inno-Pathwire was found to be substantially equivalent in its design, intended use, technology, principal of operation, and performance to the predicate device. There are no significant differences between the Inno-Pathwire and the predicate device that raise new issues of safety and effectiveness.
