Device consists of 0.014" diameter stainless steel core wire with tapered distal segment; tip coil provides radiopacity. Distal 30 cm features polyurethane jacket with hydrophilic coating; proximal section coated with PTFE. Available in 175 cm, 190 cm (extendable), and 300 cm (exchange) lengths. Used by physicians in clinical settings (e.g., cath lab) to navigate vasculature. Proximal end compatible with guide wire extensions for catheter exchange. Device provides mechanical support and guidance for interventional tools, potentially improving procedural success and patient outcomes. ## Clinical Evidence Bench testing only. Verification testing demonstrated that the device meets established acceptance criteria and performs in a manner equivalent to the predicate device. ## Technological Characteristics 0.014" diameter guide wire; stainless steel core; tungsten material; polyurethane jacket with hydrophilic coating; PTFE proximal coating; radiopaque tip coil; 175 cm, 190 cm, and 300 cm lengths. Sterilization and packaging identical to predicate. ## Regulatory 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 - HI-TORQUE WHISPER™ LS and MS Guide Wires ([K002206](/device/K002206.md)) - HI-TORQUE WHISPER™ LS and MS Guide Wires ([K013092](/device/K013092.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The proximal end of the 175 cm and 190 cm models are tapered to fit into the hypotube portion of the ACS DOC® Guide Wire Extension. This enables the physician to extend the working length of this guide wire to facilitate catheter exchanges. The wires are constructed with a stainless steel core wire. The proximal section of the core wire has a constant diameter and the distal core A3-2 {1}------------------------------------------------ segment tapers in diameter to the tip. Attached to the distal core is a tip coil that provides radiopacity. The distal 30 cm of the core wire is jacketed with a polyurethane coating that is coated with a hydrophilic coating. The proximal section of the wire is coated with polytetrafluoroethylene (PTFE). The distal tips of the guide wires are available either as a straight tip that is shapeable or as a pre shaped "J". #### Intended Use: To facilitate the placement of balloon dilatation catheters during percutaneous transluminal coronary angioplasty (PTCA) and percutaneous transluminal angioplasty (PTA) and compatible stent devices during therapeutic intravascular procedures. #### 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 predicate device. The only change is the new tungsten material. #### Performance Data: The results of the verification testing demonstrate that the HI-TORQE WHISPER™ LS and MS Guide Wires meet the established acceptance criteria and performs in a manner equivalent to the predicate device. No new safety or effectiveness issues were raised during the testing program. #### Conclusions: The HI-TOROUE WHISPER™ LS and MS Guide Wires with the new material has the same intended use, technological characteristics, performance properties, identical sterilization and substantially equivalent materials. Therefore, there are no new safety or effectiveness issues. The HI-TORQUE WHISPER™ LS and MS Guide Wires with the new material are substantially equivalent to the predicate device. {2}------------------------------------------------ Image /page/2/Picture/1 description: The image is a black and white logo for the U.S. Department of Health and Human Services.
