No
The device description and performance studies focus on the physical properties and mechanical performance of a guidewire, with no mention of software, algorithms, or data processing that would indicate AI/ML.

No.
The "Intended Use / Indications for Use" section is not found, and the device description does not indicate a therapeutic function. It describes guidewires used for procedures within "Gastroenterology and Urology," but it's not explicitly stated that device itself delivers treatment.

No

This device is a guidewire, used for navigation within the body. Its description and the performance studies focus on mechanical properties and biocompatibility, not on detecting or identifying medical conditions.

No

The device description clearly describes a physical guidewire made of NiTi core and metal coils, which is a hardware medical device.

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

Here's why:

  • Intended Use/Indications for Use: The description of the device and its intended use (Gastroenterology and Urology) clearly indicates it is a medical device used in vivo (within the body) for procedures, not for testing samples in vitro (outside the body).
  • Device Description: The description of the guidewire's physical characteristics and parameters aligns with a surgical or interventional device, not an IVD.
  • No mention of IVD specific activities: There is no mention of analyzing biological samples, detecting analytes, or providing diagnostic information based on in vitro testing.

The information provided describes a guidewire used in medical procedures within the body, which falls under the category of a medical device, not an In Vitro Diagnostic device.

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

Comparative testing was performed between LRM guidewires and Flexmedics guidewires. A product mix of three groups of LRM manufactured wires and two groups of Flexmedics product was chosen, 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. Within each 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: Visual, Dimensional Measurement - Outside Diameter, Distal Tip Flexibility, Kink Resistance, Torsional Integrity, Pull Test, 3-Point Bending Test. All test results were within prescribed specification limits.

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 each 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.

2.7 Packaging and Sterilization Information

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 Ocustomer. 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.
