Intended Use

To facilitate the placement of balloon dilatation catheters during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA). The wire is also intended to facilitate the placement of compatible stent devices during therapeutic intravascular procedures.

Device Story

Guide wire (0.012" diameter) used to facilitate placement of balloon dilatation catheters and stents during PTCA/PTA procedures. Constructed with stainless steel core; distal segment features tapers and flat for flexibility; distal tip coil is radiopaque (3 cm). Proximal section coated with PTFE; distal coiled segment coated with HYDROCOAT™ hydrophilic coating. Available in 190 cm and 300 cm lengths. Operated by physicians in clinical settings (e.g., cath lab) to navigate vasculature. Provides mechanical support and guidance for interventional devices; facilitates catheter exchanges via 300 cm length option. Benefits patient by enabling precise delivery of therapeutic devices to target coronary or peripheral lesions.

Clinical Evidence

Bench testing and in vivo animal model evaluations. Bench tests included distal tip pull (tensile strength), rotational accuracy (torqueability), and tip flexibility. Results demonstrated the device met acceptance criteria and performed comparably to predicate devices.

Technological Characteristics

Stainless steel core; 0.012" nominal diameter; 190 cm and 300 cm lengths. Proximal PTFE coating; distal HYDROCOAT™ hydrophilic coating. Radiopaque distal tip coil (3 cm). Straight or pre-shaped 'J' tip options. Mechanical device; no energy source or software.

Indications for Use

Indicated for patients undergoing percutaneous transluminal coronary angioplasty (PTCA), percutaneous transluminal angioplasty (PTA), or therapeutic intravascular procedures requiring the placement of compatible stent devices.

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.

11. Device Description:

The HI-TORQUE MIDDLE SUPPORT™ .012" Guide Wire with HYDROCOAT™ Hydrophilic Coating is a guide wire with a nominal diameter of 0.012". Like the ACS HI-TORQUE TRA VERSE® Guide Wire, the HI-TORQUE MIDDLE SUPPORT™ .012" Guide Wire is constructed from a stainless steel core. The distal segment of the guide wire includes a series of tapers and a flat, which reduce the diameter and stiffness of the distal core, thus yielding the desired flexibility and performance. The distal tip coil has a radiopaque length of 3 cm. The distal end of the guide wire is available either as a straight tip that is shapeable, or as a pre-shaped "J".

The HI-TORQUE MIDDLE SUPPORT™ .012" Guide Wire with HYDROCOAT™ Hydrophilic Coating is available in lengths of 190 cm and 300 cm exchange length. The 300 cm exchange length enables the physician ample working length of the guide wire to facilitate catheter exchanges. The proximal section of the wire is coated with polytetrafluoroethylene (PTFE). The distal, coiled segment of the wire is coated with HYDROCOAT™ Hydrophilic Coating.

- 12. Intended Use:
To facilitate the placement of balloon dilatation catheters during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA). The wire is also intended to facilitate the placement of compatible stent devices during therapeutic intravascular procedures.

### 13. Technological Characteristics:

Comparisons of the new and predicate devices show that the technological characteristics compansons of the new and presign, and intended use are substantially equivalent to the currently marketed predicate devices.

#### 14. Performance Data:

In vitro bench testing and in vivo performance evaluations demonstrated that the HIm varo occión costains and .012" Guide Wire with HYDROCOAT™ Hydrophilic Coating met the acceptance criteria and performed similarly to the predicate devices. The Counting functional tests were performed: Distal Tip Pull (Tensile Strength), Distal Tip Tomowing Tailerial torque Strength), Rotational Accuracy (Torqueability), and Tip Flexibility. I unis-to I antare (Torque Buchgan), stons in an in vivo animal model were conducted. The In addition, two performed comparably to the predicate devices and no new safety or effectiveness issues were raised during the testing program Therefore, the HI-TORQUE MIDDLE ISUPPORT™ .012" Guide Wire with HYDROCOAT™ Hydrophilic Coating may be considered substantially equivalent to the predicate devices.
