No
The device description and performance studies focus on the mechanical function of the cuff and its equivalence to a predicate device, with no mention of AI or ML.
Yes
The device is intended to aid in the prevention of deep vein thrombosis (DVT), which is a medical condition, making it a therapeutic device.
No
The device is described as a garment that connects to a pump to aid in the prevention of DVT. It does not mention detecting, diagnosing, or monitoring a medical condition.
No
The device description explicitly states it is a "cotton garment" with a "plastic inflatable bladder" and "poly vinyl tubing," indicating it is a physical hardware device, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to aid in the prevention of deep vein thrombosis in patients. This is a therapeutic and preventative application, not a diagnostic one performed in vitro (outside the body).
- Device Description: The device is a garment with an inflatable bladder that applies external pressure to the lower extremity. This is a physical intervention, not a test performed on biological samples.
- No mention of biological samples: There is no indication that this device interacts with or analyzes any biological samples (blood, urine, tissue, etc.).
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device does not fit that description.
N/A
Intended Use / Indications for Use
This product is intended for use with the Huntleigh DVT Flowtron pump to aid in the prevention of deep vein thrombosis in surgical, trauma and certain medical patients at risk for the formation of DVT. It is not intended for use on patients with known DVT or with any other intermittent compression device. Federal law restricts this device to sale by or on the order of a physician.

Summary of Performance Studies
To determine that the two devices are technologically equivalent RT Medical conducted an "Air Flow/Volume Test" and a "Cycle Test." The Air Flow/ Volume Test consisted of inflating the RTM bladder and the Huntleigh L501 bladder and timing the inflation and deflation times. They were found to be almost identical with less than one second differences detected in the inflation/ deflation times. The Cycle Test was accomplished in the same manner, however, the garment was attached to a person's calf to provide counter pressure and mimic a clinical environment. Inflation/deflation times for both cuffs were obtained and recorded with, again, virtually no difference in the times detected. The conclusion was drawn that the two devices are technologically and substantially equivalent.

Technological Characteristics:
The RTM DVT PS100 ProSoft Cuff and the Huntleigh L501 garment operate essentially the same technologically with virtually no differences detected during testing. They are both plastic bladders connected to the Huntleigh DVT Flowtron pump, inflated intermittently and applied to the lower extremities for DVT prevention.
To determine that the two devices are technologically equivalent RT Medical conducted an "Air Flow/Volume Test" and a "Cycle Test." The Air Flow/ Volume Test consisted of inflating the RTM bladder and the Huntleigh L501 bladder and timing the inflation and deflation times.
