Intended Use
The NeoSci Medical Endoluminal Brush is intended to collect a sample, which is suitable for microbiological analysis, from the inner lumen surface of an indwelling central venous catheter. The proximal nitinol shaft is encased in a polytetrafluoroethylene sheath with a hydrophilic coating applied to reduce friction. The device is contraindicated for patients with known, or suspected, allergies to nitinol, PTFE Teflon®, Nylon, stainless steel, gold, or hydrophilic coatings.
Device Description
The NeoSci Medical (NSM) Endoluminal Brush (EB) is a device similar to a very small diameter bottlebrush that can be inserted into the lumen of partially obstructed central venous catheters to collect a sample. The distal end of the device consists of a flexible tip equivalent to that of a floppy guide wire tip. Immediately proximal to the flexible tip is a segment of bristles wound into flexible. twisted (braided) stainless steel wires. The outer diameter of the bristle is selected by the user. Instructions for use recommend that the EB size be 1.2 to 2.0 times the inner diameter of the lumen to be sampled. The stainless steel wires are bonded to a nitinol shaft that extends to the proximal end of the device. The proximal nitinol shaft is encased in a polvtetrafluoroethylene sheath with a hydrophhilic coating applied to reduce friction.

No
The description focuses on the mechanical design and function of a physical brush for sample collection, with no mention of software, algorithms, or data processing that would indicate AI/ML.

No
The device is described as being intended to collect a sample, which is suitable for microbiological analysis, from the inner lumen surface of an indwelling central venous catheter. This is a diagnostic function, not a therapeutic one.

Yes

The device is intended to collect a sample for microbiological analysis, which is a diagnostic purpose.

No

The device description clearly details physical components such as a nitinol shaft, PTFE sheath, bristles, and stainless steel wires, indicating it is a hardware device.

Based on the provided information, the NeoSci Medical Endoluminal Brush is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening.
  • Device Function: The NeoSci Medical Endoluminal Brush is a tool used to collect a sample from the inner lumen surface of a catheter. It is a sample collection device, not a device that performs the analysis of the sample.
  • Intended Use: The intended use is to "collect a sample, which is suitable for microbiological analysis." The analysis itself is performed separately, likely using laboratory equipment and reagents, which would be the IVD components in this scenario.

Therefore, the NeoSci Medical Endoluminal Brush is a medical device used for sample collection, but it does not perform the in vitro diagnostic testing itself.
