Not Found

AI/ML (Artificial Intelligence / Machine Learning)

No
The device description and performance studies focus on the mechanical properties and materials of a steerable guidewire, with no mention of AI or ML capabilities.

Therapeutic

No

Explanation: The device, a guidewire, is explicitly stated as being "intended for use in angiographic procedures to introduce and position catheters and interventional devices." It facilitates the placement of other devices, but it does not directly perform a therapeutic function itself.

Diagnostic

No

The device is described as a guidewire intended for introducing and positioning catheters and interventional devices, rather than for diagnosing medical conditions. Its function is to facilitate navigation for other procedures, not to provide diagnostic information.

SaMD (Software as a Medical Device)

No

The device description clearly details physical components like a PTFE coated stainless steel core, platinum alloy coil, and solder, indicating it is a hardware device, not software-only.

IVD (In Vitro Diagnostic)

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

Intended Use: The intended use clearly states the device is for "use in angiographic procedures to introduce and position catheters and interventional devices within the coronary and peripheral vasculature, including the renal vasculature." This describes a device used within the body for a medical procedure, not a device used to test samples outside the body to diagnose a condition.
Device Description: The description details a physical guidewire with specific materials, coatings, and dimensions. This aligns with an invasive medical device used in procedures, not a diagnostic test kit or instrument.
Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting biomarkers, or providing diagnostic information based on laboratory testing.

IVD devices are used to examine specimens from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This guidewire does not fit that description.

Overview

Intended Use / Indications for 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 Description

Utilizing a proprietary process, LRM produces a PTFE coated stainless steel steerable core. The proximal portion of the core wire is coated with PTFE to provide lubricity and improve wire handling. A platinum alloy coil provides radiopacity in the distal tip. The coil is secured in its location by solder, which is attached to the core. The proximal end of the coil is attached to the core with solder. Additionally, two sections of PTFE are removed from the proximal end of the core 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: .018"
Lengths: 130cm - 300cm
Tips: Straight or shaped with various tip flexibilities
Flexibility: Floppy to Support

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

LRM performed testing to established requirements listed in FDA guidance document entitled Coronary and Cerebrovascular Guidewire Guidance, issued January 1995, and ISO 11070 Sterile Single-use Intravascular Catheter Introducers. Additionally, internal test protocol requirements were utilized to verify the guidewire can be used in the peripheral vasculature, including the renal vasculature. Configurations, including straight and shaped distal tips were inspected to established criteria. These parts were produced following current manufacturing processes and procedures. Test pieces were tested and inspected according to established specific inspection criteria requirements for visual/tactile, dimensional and mechanical attributes.

2.6 Qualification and Biocompatibility Test Data

2.6.1 Design Control

LRM is in conformance with the design control procedure requirements as specified in 21 CFR 820.30. Risk analysis was completed by means of a Failure Mode and Effect Analysis (FMEA) and all verification and validation activities resulted in the ability to demonstrate that the predetermined acceptance criteria could be met.

2.6.2 Material/Product/Process Qualification

LRM has formal quality systems in place to assure that the proposed steerable product will remain equivalent to the predicate product, and that the changes will not have an adverse affect on the safe and effective use of the product. The quality systems include Engineering Change Order Review, Material Qualification, Product Qualification, and Process Qualification. These controls are applied to each product size/group.

2.6.3 Biocompatibility Testing

The materials for the proposed device are identical to the predicate device cleared under K011968 and are identically processed and sterilized. Therefore, biocompatibility testing for the proposed device is not required.

2.7 Packaging and Sterilization Information

LRM produces guidewires on an OEM basis for other manufacturers, kit assemblers, and distributors. There is no direct distribution by LRM. A portion of the production is private label, sterile packaged to customer specifications, a fraction of that product is provided sterile to the customer.

The single packaged steerable guidewire is placed in a dispenser and then into a Tyvek®/poly pouch. The packaged product may be packaged as five or ten pouchs in a shelf carton, which are typical packaging configurations.

There will be no changes to the sterilization process for the portion of packaged product shipped sterile to the customer. For the product that is shipped bulk, the packaging design and sterilization process parameters are the customer's responsibility. LRM will not recommend that its customers modify their packaging or sterilization procedures as a result of this submission.

2.8 Intended Use Statement

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.

Dear Ms. Mortensen:

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, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

FEB 1 4 2003

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
