Intended Use

The device is intended for complex diagnostic and interventional procedures where increased body, flexibility, and low surface friction of the wire guide is needed.

Device Story

Lunderquist Extra Stiff DC Wire Guide (Extended Double Curved) is a stainless steel wire guide; PTFE-coated; 0.035-inch diameter; 260 cm or 300 cm length; 4 cm flexible distal tip with inner gold coil for radiopacity; 15 mm J-curve radius. Used in clinical settings by physicians for complex diagnostic and interventional procedures. Provides structural support and stiffness to facilitate the delivery and control of large-diameter, stiff devices through the patient's anatomy without causing damage to the lumen or vessel. Acts as a rail for catheter navigation. Benefits include enhanced maneuverability and support during challenging vascular interventions.

Clinical Evidence

Bench testing only. Testing included biocompatibility (ISO 10993-1:2009), surface testing, tape adhesion, friction, flexing, peak tensile force, ultrasound testing, torque testing, and simulated use testing (all per EN ISO 11070 where applicable). All tests met pre-determined acceptance criteria.

Technological Characteristics

PTFE-coated stainless steel wire; 0.035-inch diameter; 4 cm flexible tip with gold coil; 15 mm J-curve radius. Mechanical device; no energy source or software. Tested per ISO 10993-1 and EN ISO 11070.

Indications for Use

Indicated for patients undergoing complex diagnostic and interventional procedures requiring a wire guide with increased body, flexibility, and low surface friction.

Dear Henriette Christiansen:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration. Iisting of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

#### Predicate Devices:

The Lunderquist Extra Stiff Wire Guide and Lunderquist Extra Stiff DC Wire Guide (William Cook Europe ApS, K061670) were cleared for market on January 19, 2007. The predicate devices are PTFE-coated stainless steel wire guides with an outer diameter of 0.035 inches and lengths of 90 cm to 300 cm. For lengths 260-300 cm, a radiopaque gold coil is present on the flexible distal tip. The Lunderquist Extra Stiff DC Wire Guide features a double curved tip design. The predicate devices are intended for complex diagnostic and interventional procedures where increased body, flexibility, and low surface friction of the wire guide is needed.

### Description of the Subject Device:

The subject device, the Lunderquist Extra Stiff DC Wire Guide with an extended double curved tip, is considered a line extension of the predicate Lunderquist Extra

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

Stiff DC Wire Guides. The subject device is a PTFE-coated 0.035 inch stainless steel wire with a 4 cm flexible tip that includes an inner gold coil for enhanced visibility. The length of the device is either 260 cm or 300 cm and the J-curve radius is 15 mm. The devices have the body and stiffness required to control large diameter, stiff devices without causing damage to the patient's anatomy or the lumen of the delivery system.

# Indications for Use:

The device is intended for complex diagnostic and interventional procedures where increased body, flexibility, and low surface friction of the wire guide is needed.

{5}------------------------------------------------

- . Peak tensile force - Tested in accordance with EN ISO 11070. The pre-determined acceptance criteria were met.
- . Ultrasound test - Evaluation of PTFE coating adhesion. The predetermined acceptance criteria were met.
- . Simulated Use Test – Evaluation of device performance in a bench top model under conditions intended to simulate use. The predetermined acceptance criteria were met.
- . Torque test - Evaluation of device performance. The predetermined acceptance criteria were met.

# Conclusion:

In summary, the Lunderquist Extra Stiff DC Wire Guide - Extended Double Curved, described in this submission, met the design input requirements based on the intended use and supports the conclusion that this device does not raise new questions of safety and effectiveness. The results of these tests support a determination of substantial equivalence to the predicate devices, the Lunderquist Extra Stiff Wire Guide and Lunderquist Extra Stiff DC Wire Guide (K061670).
