The device description and performance studies focus on the physical properties and mechanical performance of a guidewire, with no mention of AI or ML capabilities.
No.
A therapeutic device is one that treats or alleviates a disease or condition. This device is a guidewire used for percutaneous entry into a peripheral vessel, which is a diagnostic or interventional accessory, not a primary therapeutic treatment itself.
No
The provided text describes a guidewire used for percutaneous entry into peripheral vessels using the Seldinger technique, which is an interventional procedure. There is no mention of the device being used to identify, measure, or monitor a medical condition, disease, or risk factor.
No
The device description clearly describes a physical guidewire made of NiTi core and stainless steel or platinum coil, with specific dimensions and physical properties. This is a hardware device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside the body (in vitro).
- Device Description and Intended Use: The provided information describes a guidewire used for percutaneous entry of peripheral vessels using the Seldinger technique. This is a procedure performed inside the body (in vivo) to access blood vessels. The guidewire is a tool used in this procedure, not a device that analyzes biological samples.
The description clearly indicates a device used for a surgical/interventional procedure, not for laboratory testing of biological samples.

Intended Use / Indications for Use
For percutaneous entry of peripheral vessel using the Seldinger technique.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparative Testing: demonstrated substantial equivalence of guidewires manufactured with a NiTi core and platinum coil by performing comparative testing between LRM guidewires and Flexmedics guidewires.
Sample size: At least two hundred (200) samples of each size (600+ total samples) were produced per standard manufacturing procedures. For each test, there were 30 samples selected.
Tests performed:
- Visual: Assess the visual aspects of the product.
- Dimensional Measurement - Outside Diameter: Micrometer measurement of the outside diameter of the product at multiple body points.
- Distal Tip Flexibility: Assess the flexibility of the product's distal tip.
- Kink Resistance: Assess the kink resistance of the core wire.
- Torsional Integrity: Assess the torsional strength of the product.
- Pull Teat: Measures the strength of the distal and proximal joints of the product.
- 3-Point Bending Test: Assess the product's body stiffness/flexibility.
Results: All test results were within prescribed specification limits.
Biocompatibility Testing: Adapted the biocompatibility testing recommendations in the FDA's General Program Memorandum #G95-1, Subject: Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing", dated May 1, 1995.
Tests performed and results:
- Cytotoxicity: The sample evoked no cytotoxic response (Grade 0)
- Hemolysis: The sample produced no hemolysis
- Acute Systemic Toxicity: No signs or symptoms of systemic toxicity were observed
- Intracutaneous Test: For all samples, the skin reactions were not significant.
- Implantation (7 Day): The reaction was not significant as compared to the negative control implant, for any of the samples.
- Sensitization: The samples were deemed to be a non-sensitizer.
- Pyrogen Test: The samples did not produce a pyrogenic response.

2.5 Substantial Equivalence Data
2.5.1 Background Information
In order to demonstrate substantial equivalence of guidewires manufactured with a NiTi core and platinum coil, LRM performed comparative testing between LRM guidewires and Flexmedics guidewires.
LRM chose a product mix of three groups of LRM manufactured wires and two groups of Flexmedics product, based on the available Flexmedics products of .014" and .018" configurations. LRM samples were manufactured following current manufacturing processes and procedures. Flexmedics products were purchased by LRM, complete in packaging. All samples were sterilized prior to testing.
- 2.5.2 Comparative Test Data
Within cach of the groups, production samples were made; at least two hundred (200) samples of each size (600+ total samples) were produced per standard manufacturing procedures. For each test, there were 30 samples selected. Some of the tests are destructive in nature which requires the selection of additional sets of 30 samples to perform other tests.
The following product qualification tests were performed:
- 2.5.2.1 Visual: Assess the visual aspects of the product.
- 2.5.2.2 Dimensional Measurement - Outside Diameter: Micrometer measurement of the outside diameter of the product at multiple body points.
- 2.5.2.3 Distal Tip Flexibility: Assess the flexibility of the product's distal tip.
- 2.5.2.4 Kink Resistance: Assess the kink resistance of the core wire.

Packaging and Sterilization Information 2.7
LRM produce 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 CCA guidewire is placed in a dispenser and then into a Tyvek®/poly pouch. The packaged product may be packaged as five or ten pouches in a shelf carton, which are typical packaging configurations.
There will be no changes to the sterilization process for the portion of the 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.
