The description focuses on the physical characteristics and performance testing of a guidewire, with no mention of AI or ML capabilities.
No
The device is described as a guidewire to facilitate the placement of other devices during diagnostic and interventional procedures, not to directly treat a medical condition.
No
Explanation: The "Intended Use / Indications for Use" states that the device is "to facilitate the placement of devices during diagnostic and interventional procedures." This indicates it is an accessory used during diagnostic procedures, not a diagnostic device itself. Its features, such as outside diameter, length, and tips, are physical specifications for guiding other devices, not for diagnosing conditions.
No
The device description clearly outlines physical components (Nickel Titanium core, jacket, coating) and physical parameters (Outside Diameter, Lengths, Tips), indicating it is a hardware medical device. The performance studies also involve physical testing (Lubricity, Pull Test, Bending Test, etc.).
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "To facilitate the placement of devices during diagnostic and interventional procedures." This describes a tool used within the body to aid in medical procedures, not a device used to test samples outside the body to diagnose conditions.
- Device Description: The description details a physical guidewire with specific dimensions, materials, and coatings, designed for insertion into the body. This aligns with an invasive medical device, not an in vitro diagnostic.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information based on laboratory testing.
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This guidewire's function is purely mechanical and procedural.

Intended Use / Indications for Use

Summary of Performance Studies
LRM performed comparative testing between LRM hydrophilic guidewires and Terumo guidewires to demonstrate equivalence. LRM chose a product mix of three groups of wires, based on Terumo products of .018", .035" and .038" standard configurations, including straight and shaped distal tips. LRM samples were produced following current manufacturing processes and procedures. Terumo product was purchased by LRM, complete in packaging. All samples were sterilized prior to testing.
Within each of the three groups, production samples were made representing the minimum (smallest size), maximum (largest size) and mode (most common size). For each test series, samples were produced per standard manufacturing procedures. For each test type, either fifteen (15) or ten (10) test samples were selected. Some of the tests are destructive in nature which required the selection of additional sets of fifteen (15) or ten (10) samples to perform other tests.
The following product qualification tests were performed:
- Visual: Assess the product for visual appearance, such as tip integrity and jacket durability (cuts, splits, seams, etc., any indication that the tip has been compromised).
- Dimensional Measurement Outside Diameter, Dry and after 10 minute soak and after 40 minute soak in normal saline : Laser micrometer measurement of the outside diameter of the guidewire at multiple body points.
- Lubricity: Measures the force required to insert and withdraw the guidewire within a catheter lumen standardized to each guidewire diameter.
- Pull Test: Measures the strength of materials and joints in the guidewire.
- 3-Point Bending Test: Assess guidewire body stiffness/flexibility.
- Coating Durability: Measures the lubricity before and after multiple catheter insertions and withdrawals.
- Distal Tip(J) Memory: Assess the memory of the distal tip form of shaped product.
- Kink Resistance: Measures the kink resistance properties of product made from kink resistance materials or products that are designed to have kink resistance properties.
- Linear Stiffness: Measures the linear tip flexibility.
- Torque Control: Assess guidewire torque response and rotational control to allow placement of the distal tip at a desired location in a 360 degree circle when controlled from the proximal end of the guidewire. Control may be clockwise or counter-clockwise.
- Torque Fatigue: Assess the torqueable strength of a guidewire.
RESULTS: All test results were within prescribed specification limits.
Biocompatibility Testing:
LRM adapted the biocompatibility testing recommendations in the FDA's General Program Memorandum #G95-1 Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing", dated May 1, 1995.
| TEST PERFORMED | TEST RESULTS |
|---|---|
| Acute Systemic Toxicity | No signs or symptoms of Systemic Toxicity were observed for any of the samples. |
| Cytotoxicity (MEM) | The samples evoked a mild cytotoxic response (Grade 1), when tested at 48 hours. The test material passed the assay. |
| Hemolysis | The samples did not produce hemolysis. |
| Intracutaneous Test | For all samples, skin reactions were not significant. |
| Pyrogen (Material Mediated) | The samples did not produce a pyrogenic response. |
| Inhibition and Enhancement | No endotoxin detected at 0.03 eu/ml |
| Sensitization | The samples were deemed to be a weak sensitizer. |
| Thrombo In-Vitro (Plate Method) | The test article was considered nonthrombogenic |

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 small portion of the production is private label, single packaged to customer specifications, a fraction of that product is provided sterile to the customer.
The single packaged polymer/hydrophilic coated guidewires s placed in a dispenser and then into a Tyvek/poly pouch, along with a tray containing a torque device. The product may be packaged as five (5) pouches in a shelf carton five(5) pack, which is a typical packaging configuration.
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.
