Intended Use

The HI-TORQUE WHISPER Guide Wire is intended to aid in the placement of a Guidant implantable coronary venous lead in the coronary venous vasculature.

Device Story

The HI-TORQUE WHISPER guide wire is a catheter guide wire used to assist physicians in placing implantable coronary venous leads. The device consists of a high-tensile stainless steel tapered core with a flexible distal tip. The proximal portion is jacketed with PTFE, while the distal portion is jacketed with polyurethane and finished with a hydrophilic coating to enhance lubricity. Available in various support levels (LS, MS, ES, DS, EDS) and tip configurations (straight or pre-formed 'CS-J' for coronary sinus access), the wire is inserted into the coronary venous vasculature. The straight tip allows for manual shaping to match patient anatomy, while the CS-J tip provides a pre-formed shape for convenience. By facilitating lead placement, the device supports the implantation of cardiac rhythm management systems, potentially benefiting patients requiring venous lead therapy.

Clinical Evidence

Bench testing only. Verification testing demonstrated that the guide wires meet established acceptance criteria and perform in a manner equivalent to the predicate devices.

Technological Characteristics

Stainless steel tapered core; polyurethane distal jacket; PTFE proximal jacket; hydrophilic coating; 0.014" or 0.0145" diameter; 190 cm length; straight or pre-formed 'CS-J' distal tip; manual shapeability for straight tips; sterile.

Indications for Use

Indicated for patients requiring placement of a Guidant implantable coronary venous lead within the coronary venous vasculature.

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.

#### Summary of Substantial Equivalence:

The design, materials, method of delivery and intended use features of HI-TORQUE WHISPER LS, MS/MS CS-J, ES/ES CS-J, DS/DS CS-J, and EDS/EDS CS-J Guide Wires are substantially equivalent with regard to these features in their predicate device, the HI-TORQUE WHISPER Guide Wires (K020340/March 1, 2002, and K021285/May 2, 2002).

#### Device Description:

The general guide wire design consists of a stainless steel tapered core with a flexible tip, jacketed by polyurethane on the distal portion of the wire and polytetrafluoroethylene (PTFE) on the proximal portion of the wire. The polyurethane is subsequently covered with a hydrophilic coating to increase lubricity. The guide wires are available with either a straight distal tip that is shapeable, or as a pre-formed 'J' distal tip shaped specifically for accessing the coronary sinus (designated 'CS-J'). The straight tip can be manually shaped to accommodate specific patient anatomy or physician preference; the CS-J shape provides the convenience of an existing 'J' shape without manual shaping.

The HI-TORQUE WHISPER LS, MS/MS CS-J, and ES/ES CS-J guide wires with Hydrocoat hydrophilic coating are guide wires with a 0.014" maximum diameter and a length of 190 cm. The HI-TORQUE WHISPER DS/DS CS-J and EDS/EDS CS-J guide wires with Hydrocoat hydrophilic coating are guide wires with a 0.0145" maximum diameter and a length of 190 cm. These guide wires are all labeled as 0.014". These wires are constructed with a high tensile (Hyten) stainless steel core wire having a nominal diameter of 0.0128" (LS/MS versions) or 0.0132" (ES versions). The distal segment of each guide wire consists of a series of unique tapers and grinds which reduce the diameter and support at the distal core, thus yielding the desired flexibility and performance characteristics.

#### Intended Use:

The HI-TORQUE WHISPER Guide Wire is intended to aid in the placement of a Guidant implantable coronary venous lead in the coronary venous vasculature.

## Technological Characteristics:

Comparisons of the proposed and predicate device show that the technological characteristics such as materials, performance characteristics, sterilization and packaging are identical or substantially equivalent to the currently marketed device.

#### Performance Data:

The results of the verification testing demonstrate that the HI-TORQUE WHISPER LS, MS/MS CS-J, ES/ES CS-J, DS/DS CS-J, and EDS/EDS CS-J Guide Wires meet the established acceptance criteria and perform in a manner equivalent to the predicate device. No new safety or effectiveness issues were raised during the testing program.

#### Conclusions:

The Guidant CRM HI-TORQUE WHISPER LS, MS/MS CS-J, ES/ES CS-J, DS/DS CS-J, and EDS/EDS CS-J Guide Wires have the same intended use, materials, technological characteristics, performance properties, and use identical sterilization processes as the Guidant VI Whisper LS and MS (Enhanced Radiopacity) guidewires and the Guidant CRM HI-TORQUE guidewires; there are no new safety or effectiveness issues. The modified HI-TORQUE WHISPER Guide Wires are substantially equivalent to the predicate devices.
