The 510(k) summary describes a physical medical device (a dialysis catheter) and its performance testing. There is no mention of software, algorithms, or any technology that would suggest the use of AI or ML. The description focuses on the physical characteristics and functional performance of the catheter.
Yes
The device is a dialysis catheter, which is used to treat chronic hemodialysis and apheresis, and is therefore a therapeutic device.
No
The device is described as a "chronic hemodialysis catheter," which is used for treatment (hemodialysis and apheresis) rather than diagnosing a condition.
No
The device description clearly identifies the device as a physical catheter, a hardware component, and the performance studies focus on material and functional testing of this hardware. There is no mention of software as the primary or sole component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "chronic hemodialysis and apheresis." These are procedures performed directly on the patient's blood within their body, not on samples of blood or other bodily fluids outside the body for diagnostic purposes.
- Device Description: The description details a catheter designed for insertion into the body to facilitate blood flow for treatment. This is a therapeutic device, not a diagnostic one.
- Lack of IVD Characteristics: The description does not mention any components or functions related to analyzing samples, detecting analytes, or providing diagnostic information based on in vitro testing.
IVD devices are specifically designed to examine specimens derived from the human body (like blood, urine, tissue) to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. This device's function is to facilitate a medical procedure (hemodialysis/apheresis) directly on the patient.

(a)
Identification. A blood access device and accessories is a device intended to provide access to a patient's blood for hemodialysis or other chronic uses. When used in hemodialysis, it is part of an artificial kidney system for the treatment of patients with renal failure or toxemic conditions and provides access to a patient's blood for hemodialysis. The device includes implanted blood access devices, nonimplanted blood access devices, and accessories for both the implanted and nonimplanted blood access devices.(1) The implanted blood access device is a prescription device and consists of various flexible or rigid tubes, such as catheters, or cannulae, which are surgically implanted in appropriate blood vessels, may come through the skin, and are intended to remain in the body for 30 days or more. This generic type of device includes various catheters, shunts, and connectors specifically designed to provide access to blood. Examples include single and double lumen catheters with cuff(s), fully subcutaneous port-catheter systems, and A-V shunt cannulae (with vessel tips). The implanted blood access device may also contain coatings or additives which may provide additional functionality to the device.
(2) The nonimplanted blood access device consists of various flexible or rigid tubes, such as catheters, cannulae or hollow needles, which are inserted into appropriate blood vessels or a vascular graft prosthesis (§§ 870.3450 and 870.3460), and are intended to remain in the body for less than 30 days. This generic type of device includes fistula needles, the single needle dialysis set (coaxial flow needle), and the single needle dialysis set (alternating flow needle).
(3) Accessories common to either type include the shunt adaptor, cannula clamp, shunt connector, shunt stabilizer, vessel dilator, disconnect forceps, shunt guard, crimp plier, tube plier, crimp ring, joint ring, fistula adaptor, and declotting tray (including contents).
