The summary describes a standard sequential compression device with a mobile app for tracking and control. There is no mention of AI or ML in the device description, intended use, or performance studies. The "smart device app" and data transmission are for basic control and monitoring, not for intelligent analysis or adaptation.
Yes
The device is indicated for medical treatments such as preventing DVT, enhancing circulation, diminishing pain and swelling, reducing wound healing time, treating stasis dermatitis, venous stasis ulcers, arterial and diabetic leg ulcers, and chronic venous insufficiency, and reducing edema. These are all therapeutic applications.
No
The device is a sequential compression device used for therapeutic purposes like preventing DVT, enhancing circulation, and treating venous issues. It does not perform any diagnostic functions like analyzing data to identify a medical condition.
No
The device description explicitly states that the Cirvo Compression System includes a physical compression unit with a motor, an AC charger, and a smart device app. This indicates the presence of hardware components beyond just software.
Based on the provided information, the Radial Medical Cirvo Compression System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: An IVD is a medical device used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device Function: The Cirvo Compression System is a mechanical device that applies external pressure to the calf to improve blood circulation and reduce swelling. It does not analyze biological samples.
- Intended Use: The stated intended uses are related to physical conditions (DVT prevention, edema reduction, wound healing assistance, etc.) and are achieved through mechanical compression, not through the analysis of biological markers.
- Device Description: The description focuses on the mechanical components (motor, compression unit, straps) and software for control and monitoring, not on any components for sample handling or analysis.
Therefore, the Cirvo Compression System falls under the category of a therapeutic or physical medicine device, not an In Vitro Diagnostic device.

Device Description
The Cirvo Compression System is a light-weight, mobile, sequential compression device (SCD) placed around the calf that sequentially compresses the calf to augment blood flow. SCD's are used in both the hospital and home setting. most commonly to prevent deep vein thrombosis (DVT), heal venous leg ulcers (VLU) and reduce swelling. The Cirvo Compression System includes three components: the Cirvo sequential compression device, an AC charger and a smart device app.
The Cirvo compression unit generates compression cvcles using a small motor to sequentially cycle the compression unit on the calf. The Cirvo sequential compression device is placed around the lower leg using a detachable shin guard with self-aligning magnets, with the padded compression unit aligned on the calf. Proper fitting is achieved by adjusting a pair of hook and loop straps. The Cirvo compression system continuously monitors and maintains the prescribed compression therapy, records the duration of therapy session as well as compliance with the prescribed therapy. Therapy can be initiated and stopped using either the app interface on a smart device or using the capacitive touch sensor on the compression unit. Patients can track their progress with the app and can opt in to have text reminders sent to reinforce compliance with their therapy and notifications sent to their physician. All data is saved and transmitted using high-level, AES-128 encryption.
