No.
The device is described as an introducer sheath for diagnostic and interventional devices, not as a device that provides therapy itself.
No
The device is an introducer sheath, which is used to introduce diagnostic or interventional devices into the human vasculature. It is not itself a diagnostic device, but rather a tool to facilitate the use of other devices.
No
The device description clearly outlines physical components like a Sheath, Dilator, and Guidewire, and the performance studies involve bench testing of these physical attributes. There is no mention of software as a component or function of the device.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "introduction of diagnostic and interventional devices inserted into the human vasculature." This describes a device used during a medical procedure to facilitate the use of other devices, not a device used to perform a diagnostic test on a sample taken from the body.
- Device Description: The description details a physical device (sheath, dilator, guidewire) used for accessing blood vessels. It does not mention any components or processes related to analyzing biological samples (like blood, urine, tissue, etc.) outside of the body.
- Lack of IVD Characteristics: There is no mention of reagents, assays, sample collection, or any other elements typically associated with in vitro diagnostic devices.
The device is clearly intended for use in vivo (within the living body) to aid in diagnostic and interventional procedures, rather than performing a diagnostic test in vitro (outside the living body).

Device Description
The Super Sheath Introducer Sheath (hereinafter referred to as the "Subject Device") is used to introduce diagnostic or interventional devices into a blood vessel. The Subject Device is available in two products: one consisting of a Sheath and Dilator (Super Sheath Introducer Sheath without Guidewire), and the other consisting of a Sheath, Dilator, and Guidewire (Super Sheath Introducer Sheath with Guidewire), similar to the Predicate Device K121504. These devices are provided sterile and intended for single use, and the shelf-life is three years.
The main component of the Sheath consists of a Sheath hub, a Sheath shaft connected to the Sheath hub, and a three-way stopcock valve connected to the hub with a side port tube. The Sheath shaft is 3.3 French size and available in 5cm and 7cm lengths. The Sheath hub contains a hemostatic valve and has a suture wing. The shape and dimensions of the three-way stopcock luer connector are modified to comply with the new applicable standard ISO 80369-7:2021.
The Dilator has an open, tapered plastic tube for Guidewire insertion. The Dilator tube is press-fit into the inner hub with a bushing. The length of the Dilator tube corresponds to the length of the Sheath shaft, which is longer and available in 10.5 cm and 12.5 cm.
The 0.018" Guidewire is the smallest size Guidewire and a 40 cm long, thin, flexible wire with a inserter attached to the tip. This Guidewire is a legally marketed product which is cleared by the Food and Drug Administration (K021990).
The upper cap and suture wing of the Sheath hub, and the Dilator hub are colored purple. The Dilator tube and the inserter are colored blue. And the unvented cap of the three-way stopcock is pink.
