• Device Name: CORONARY PERIPHERAL AND RENAL STEERABLE GUIDEWIRE
• Applicant: Lake Region Mfg., Inc.
• Product Code: DQX · Cardiovascular
• Decision Date: Sep 16, 2004
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 870.1330
• Device Class: Class 2

Intended Use

Lake Region's steerable guidewires are intended for use in angiographic procedures to introduce and position catheters and interventional devices within the coronary and peripheral vasculature, including the renal vasculature. The steerability feature allows the guidewire to be torqued to facilitate navigation through the vasculature.

Device Story

The device is a steerable guidewire consisting of a PTFE-coated stainless steel core ground at the distal end for flexibility. It features a distal tip coil soldered to the core and additional radiopaque marker coils. The device is used by physicians in clinical settings to navigate coronary, peripheral, and renal vasculature. The guidewire is torqued by the operator to facilitate navigation, allowing for the introduction and positioning of catheters and interventional devices. It is offered in various lengths (130cm-300cm), diameters (.014"-.018"), and tip configurations (straight or shaped). The device is provided to OEM manufacturers, kit assemblers, and distributors, and may be supplied sterile or bulk.

Clinical Evidence

No clinical data. Equivalence was established through bench testing, including visual, tactile, dimensional, and mechanical attribute inspections. Biocompatibility was established based on the use of materials identical to the predicate device and a history of proven biocompatibility.

Technological Characteristics

Materials: PTFE-coated stainless steel core, soldered distal tip coil, radiopaque marker coils. Dimensions: .014"-.018" diameter, 130cm-300cm length. Features: Shapeable straight or preshaped tip, optional MDX (silicone) coating. Connectivity: None. Sterilization: Ethylene oxide (for sterile-packaged units).

Indications for Use

Indicated for use in angiographic procedures to introduce and position catheters and interventional devices within the coronary, peripheral, and renal vasculature in patients requiring vascular navigation.

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.

## Device Trade Name/Proprietary Name:

LRM produces guidewires on an OEM basis for other manufacturers, kit assemblers, and distributors. Consequently there are a large number of trade and proprietary names not including or associated with LRM. LRM has no proprietary names of its own to be included with this submission.

## Device Common Names/Usual Names and Classification Names:

These devices are commonly known as guides, guidewires, or spring The current classification names, and product codes are quidewires. Angiographic Guidewire (74HAP), Catheter Guidewire (74DQX), and Radiological Catheter Guidewire (74JAJ).

Classification of Devices:

Olassification of Donoos listed above were originally classified as Class II devices by the Neurology (84HAD), Cardiovascular (74DQX), and Radiology (90JAJ) Review Panels, respectively.

### Applicability of Performance Standards:

LRM has determined that no mandatory performance standards have been established for these devices under Section 514 of the Medical Amendments to Federal Food, Drug, and Cosmetic Act or by any subsequent regulatory action. LRM has also determined that there are no applicable voluntary standards.

## Labels, Labeling and Advertising:

LRM produces cardiovascular and vascular guidewires on an OEM basis for ether manufacturers kit assemblers and distributors. There is no direct other manafacturer int ages to the customer controlled labels labeling or diotion by Erinals are at their discretion including the resolution of any promotion regulatory obligations. A fraction of the total production bears LRM controlled labels and labeling.

### Device Description:

This device is a guidewire with a PTFE coated stainless steel core that has been ground at the distal end to provide the appropriate tip flexibility. boon ground for the coils are joined to the core at the ground end and a distal tip coil is soldered to the core. The proximal PTFE coated portion of the core has two sections of the PTFE removed to aid in estimating guidewire positioning.

The product is offered with a shapeable straight tip or in a preshaped configuration. The guidewires are optionally coated with MDX (silicone). The guidewires are bound by the following parameters:

| Outside Diameter: | .014" - .018" |
|-------------------|---------------------------------------------------|
| Lengths: | 130cm - 300cm |
| Tips: | Straight or shaped with various tip flexibilities |

## Engineering Specifications:

The design specifications are the same for the proposed device as they are for the LRM predicate device [reference 510(k)s K022813 and K011968] with the exception of the smaller outer diameter and the additional radiopaque marker coils soldered to the core proximal to the existing radiopaque coil. The finished device must meet the same basic design criteria as the predicate device.
