The device description and intended use focus on a mechanical brush for sample collection, with no mention of AI/ML terms, image processing, or data analysis capabilities.
No
The device is described as an accessory to central venous catheters and is intended to collect samples for microbiological analysis, which is a diagnostic purpose, not a therapeutic one.
No
The device is intended to collect a sample for microbiological analysis, not to perform the analysis itself. It is a sample collection accessory, not a diagnostic tool.
No
The device description clearly outlines physical components like brushes, wires, handles, syringes, and other accessories, indicating it is a hardware-based medical device.
Based on the provided information, the CRS Endoluminal Brush is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The primary intended use is to collect a sample (biofilm or fibrin) from a catheter for microbiological analysis. The device itself is a tool for sample collection, not for performing the diagnostic test on the sample.
- Device Description: The description focuses on the physical components of the brush and the kit, designed for the mechanical act of sample collection.
- Lack of Diagnostic Function: There is no mention of the device performing any analysis, measurement, or interpretation of the sample to provide diagnostic information. The sample is collected and then suitable for microbiological analysis, which would be performed using separate IVD devices or laboratory procedures.
IVD devices are typically used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. The CRS Endoluminal Brush facilitates the collection of the specimen, but it doesn't perform the diagnostic analysis itself.

Device Description
The CRS Endoluminal Brush product line is an accessory to central venous catheters. Each single use Endoluminal Brush kit contains 2 pairs of latex free gloves, 1- 70% isopropyl alcohol cleaning agent, 1 fibrin brush in transport bag, 1- 10 cc syringe, 2 patient labels, 1 medical drape, 1 over wrap, and Instructions for Use. The brush consists of nylon bristles wound into a flexible stainless steel wire, which is further wound into a tubular, metal, rigid handle. The Brush is enclosed within a no ratiner would at the distal end and is attached to a standard luer lock at its proximal end. The luer lock fitting complies with catheter manufacturers' requirement that only luer-lock connections be used with catheters. The various CRS Endoluminal Brush products defined by the product codes differ mainly in the length of the flexible wire and the diameter of the Brush bristles.

§ 880.5970 Percutaneous, implanted, long-term intravascular catheter.
(a)
Identification. A percutaneous, implanted, long-term intravascular catheter is a device that consists of a slender tube and any necessary connecting fittings, such as luer hubs, and accessories that facilitate the placement of the device. The device allows for repeated access to the vascular system for long-term use of 30 days or more, and it is intended for administration of fluids, medications, and nutrients; the sampling of blood; and monitoring blood pressure and temperature. The device may be constructed of metal, rubber, plastic, composite materials, or any combination of these materials and may be of single or multiple lumen design.(b)

Dear Mr. Kamm:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions aga\inst misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
