Intended Use

The SplitWire Percutaneous Transluminal Angioplasty Scoring device is indicated for the use with percutaneous transluminal angioplasty (PTA) catheters to facilitate dilation of stenoses in the iliac, femoral, ilio-femoral, popliteal, infrapopliteal, and renal arteries and treatment of obstructive lesions of native or synthetic arteriovenous dialysis fistulae.

Device Story

SplitWire is an accessory device used with percutaneous transluminal angioplasty (PTA) balloon catheters to facilitate lesion dilation. It consists of two wires joined at the distal end: a tracking wire for positioning the PTA balloon and a scoring wire with a triangular profile. During balloon inflation, the scoring wire applies concentrated pressure to the lesion. The distal section features a radiopaque coil and soft polymer coating for atraumatic navigation. Used by clinicians in interventional settings, the device aids in treating arterial stenoses and dialysis fistula obstructions. By focusing balloon pressure, it potentially improves dilation efficacy compared to standard balloon angioplasty. The device is single-use and compatible with various PTA balloon diameters and lengths.

Clinical Evidence

No human clinical data provided. Evidence consists of bench testing (ISO 10555-1, angioplasty catheter dilation performance, compatibility testing, simulated use) and in vivo GLP animal testing to confirm safety and functional equivalence to the predicate.

Technological Characteristics

Two-wire system (scoring wire with triangular profile, tracking wire with radiopaque markers); .014" scoring member; .035" or .018" guidewire compatibility; distal radiopaque coil; soft polymer coating; ethylene oxide sterilization; standalone accessory device; non-integrated with balloon.

Indications for Use

Indicated for patients requiring dilation of stenoses in iliac, femoral, ilio-femoral, popliteal, infrapopliteal, and renal arteries, and treatment of obstructive lesions in native or synthetic arteriovenous dialysis fistulae, when used with PTA catheters.

Regulatory Classification

Identification

A percutaneous catheter is a device that is introduced into a vein or artery through the skin using a dilator and a sheath (introducer) or guide wire.

#### 2. Name of the Device:

SplitWire Percutaneous Transluminal Angioplasty Scoring Device

#### Predicate Device Information: 3.

VascuTrak PTA Dilation Catheter (K063657)

#### Device Description: 4.

The SplitWire Percutaneous Transluminal Angioplasty Scoring Device is designed to facilitate the dilatation of stenoses.

The SplitWire device is intended to be used with a percutaneous transluminal angioplasty balloon catheter.

The SplitWire device consists of two (2) wires that are joined at the distal end. The larger wire (scoring wire) has a triangular profile near the distal end, that when the balloon is inflated applies pressure to the lesion being treated. The smaller wire (tracking wire) is used to position the PTA balloon catheter in the

{4}------------------------------------------------

proper location adjacent to the lesion. There are two (2) radiopaque markers bands on the tracking wire that indicate the location for the PTA balloon catheter placement.

The distal section of the SplitWire is designed to be atraumatic with a radiopaque coil for visibility. The distal section is coated with a soft polymer.

The device is used in the same manner as the predicate device and other substantially equivalent 510(k) cleared devices.

#### 5. Intended Use:

The SplitWire Percutaneous Transluminal Angioplasty Scoring device is indicated for the use with perculaneous transluminal angioplasty (PTA) catheters to facilitate dilation of stenoses in the iliac, femoral, illio-femoral, popliteal, infrapopliteal, and renal arteries and treatment of obstructive lesions of native or synthetic arteriovenous dialysis fistulae.

#### 7. Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence:

Comparative functional testing to the predicated devices was performed based on device attributes, performance and safety. Bench testing was conducted to ensure that the SplitWire device performed as intended. Testing included:

- General requirements for intravascular catheters: ISO 10555-1
- Angioplasty Catheter Dilation Performance Testing ●
- . Compatibility with PTA Balloon Catheters
- . Simulated Use Testing

In Vivo GLP animal testing (Reference Exhibit 8) showed equivalence during use for safety. Testing results revealed the subject device to be substantially equivalent to the predicate device.

#### 8. Conclusions:

The subject device, the SplitWire Percutaneous Transluminal Angioplasty Scoring Device, has the same intended use as the predicate device, the VascuTrak PTA Dilation Catheter (K063657). Bench testing and non-clinical testing supplied within our submission demonstrates that there are not any differences in their technological characteristics thereby not raising any new questions of safety and effectiveness. Therefore, the SplitWire Percutaneous Transluminal Angioplasty Scoring Device is substantially equivalent to the predicate device, the VascuTrak PTA Dilation Catheter (K063657).
