Intended Use

The intended use of the ACS HI-TORQUE WIGGLE™ Guide Wire with MICROGLIDE® Coating is to facilitate the placement of the catheter by orienting the catheter tip during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA) and other interventional diagnostic or therapeutic procedures.

Device Story

The ACS HI-TORQUE WIGGLE™ Guide Wire is a 0.014-inch diameter stainless steel guide wire used to facilitate catheter placement during interventional procedures. It features a distal tip with sinusoidal waves (4.5–6.5 cm from the tip) to assist in orientation. The distal section is coated with MICROGLIDE® and the proximal shaft with polytetrafluoroethylene. It is available in 190 cm (extendable) and 300 cm (exchange) lengths. Used by physicians in clinical settings, the wire provides mechanical support and navigation for catheters. It is a passive mechanical device; it does not process data or provide automated outputs. Clinical benefit is derived from improved catheter maneuverability and placement during coronary and peripheral interventions.

Clinical Evidence

Bench testing only. Tests included Distal Tip Pull, Distal Tip Turns-to-Failure, Rotational Accuracy, and Tip Flexibility. In vitro heart model studies were also conducted to verify intended performance.

Technological Characteristics

0.014-inch diameter stainless steel guide wire. Features distal sinusoidal waves. Coatings: MICROGLIDE® (distal), polytetrafluoroethylene (proximal). Radiopaque tip (straight or J-shape). Lengths: 190 cm (extendable) and 300 cm (exchange). Passive mechanical device; no energy source or software.

Indications for Use

Indicated for patients undergoing percutaneous transluminal coronary angioplasty (PTCA), percutaneous transluminal angioplasty (PTA), or other interventional diagnostic or therapeutic procedures requiring catheter placement.

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.

Special Controls

*Classification.* Class II (special controls). The device, when it is a torque device that is manually operated, non-patient contacting, and intended to manipulate non-cerebral vascular guide wires, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 870.9.

Predicate Devices

• ACS HI-TORQUE FLOPPY II® EXTRA SUPPORT Guide Wire with MICROGLIDE® Coating (K913353)
• ACS Angioscone Guide Wire (K883000)

#### 4. Device Description:

The ACS HI-TORQUE WIGGLE™ Guide Wire with MICROGLIDE® Coating is a guide wire with a nominal diameter of 0.014″ and available in two lengths: a 190 cm extendable length and a 300 cm exchange length. The proximal end of the 190 cm models are tapered to fit into the hypotube portion of the ACS DOC® Guide Wire Extension.

The wire is constructed from stainless steel, the distal end of this guide wire has a radiopaque tip that is available either as a straight, shapeable configuration or as a preshaped J. The distal end of the wire has sinusoidal waves manufactured approximately 4.5 cm - 6.5 cm from to the distal tip. The guide wire has proximal markers at 90 and 100 cm from the distal tip. MICROGLIDE® Coating is applied to the distal section of the guide wire, the proximal shaft is coated with polytetrafluoroethylene.

#### Intended Use: న్న

The intended use of the ACS HI-TORQUE WIGGLE™ Guide Wire with MICROGLIDE® Coating is to facilitate the placement of the catheter by orienting the catheter tip during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA) and other interventional diagnostic or therapeutic procedures.

### Technological Characteristics: Q.

Compansons of the Wiggle Guide Wire and predicate Hi-Torque Floppy II® Extra Support Guide Wire show that technological characteristics such as materials, biocompatibility, performance properties, sterilization, and packaging are identical or substantially equivalent to the predicate device. Similar in design to the Angioscope Guide Wire, the WIGGLE™ Guide Wire has a sinusoidal wave design manufactured in the distal tip section of the wire.

#### 7. Performance Data:

Bench testing was performed to demonstrate that the ACS HI-TORQUE WIGGLE™ Guide Wire with MICROGLIDE® Coating met the acceptance criteria and performed similar to the predicate ACS HI-TORQUE FLOPPY II® EXTRA SUPPORT Guide Wire with MICROGLIDE® Coating. The following tests were performed: Distal Tip Pull Test, Distal Tip Turns-to-Failure Test, Rotational Accuracy Test, Tip Flexibility Test.

Additionally, in vitro heart model studies were performed to substantiate the intended use of the ACS HI-TORQUE WIGGLE™ Guide Wire. The results of the heart model study demonstrated that the new wire performs as intended.

The results from the bench tests showed that the new ACS HI-TORQUE WIGGLE™ Guide Wire with MICROGLIDE® Coating is substantially equivalent to the predicate wires and performs as intended. No new safety or effectiveness issues were raised during the testing program.

#### 8. Conclusions:

The ACS HI-TORQUE WIGGLE™ Guide Wire has shown to have similar design and technological characteristics, identical materials, sterilization and packaging, and no new safety or effectiveness issues compared to the predicate wires, therefore, the ACS HI-TORQUE WIGGLE™ Guide Wire with MICROGLIDE® Coating may be considered safe and effective for its intended use.
