The VenaPro Vascular Therapy System is intended to be an easy to use portable system, prescribed by a physician, for use in the home or clinical setting to help prevent the onset of DVT in patients by stimulating blood flow in the extremities (stimulating muscle contractions). This device can be used to:
- Aid in the prevention of DVT;
- Enhance blood circulation;
- Diminish post-operative pain and swelling;
- Reduce wound healing time;
- Aid in the treatment and healing of stasis dermatitis, venous stasis ulcers, arterial and diabetic leg ulcers, chronic venous insufficiency and reduction of edema in the lower limbs.
The unit can also be used as an aid in the prophylaxis for DVT by persons expecting to be stationary for long periods of time.
The VenaPro Vascular Therapy System is a lightweight, portable, rechargeable battery powered prescriptive device. It is intended to be used in the home or clinical setting by or under the direction of a medical professional to help stimulate blood flow as an aid in the prevention of deep vein thrombosis (DVT).
The system utilizes pneumatically controlled, single chamber cuffs actuated by an electronically controlled air pump unit and solenoid valve. All pump, battery and control components are protectively housed in a plastic case that is permanently attached to a single use inflatable cuff. A single tactile touch control switch, tri-color LED for ON, LOW BATTERY, CHARGING and CHARGE COMPLETED indication, and a blue LED (for indicating a leak or low pressure alarm) provides for user interface. There is also a port for connecting the battery charger/AC adapter plug, and a currently unused port for future use in usage data reporting.
The leg wrap (cuff) component consists of a Polyvinyl Chloride (PVC) air bladder encased inside a soft, non-woven medical fabric (a Polyester blended medical fabric) or equal , which is adhered to the PVC air bladder. The units are supplied clean, non-sterile, packaged in pairs (1 left and 1 right side).
In operation, the user simply turns the power ON via the single button I/O control switch. A single user "cuff" containing air bladders is permanently connected to the unit. The control unit then fills the cuff to a pre-determined pressure (50 mmHg). Cuff pressure is monitored by an internal pressure switch and system software. Once the pressure reaches the proper level, the pump is turned OFF for an approximately 50 second "rest" period, and the cuff deflates to ambient pressure through a valve inside the plastic case. After the "rest" period, the cycle repeats until the unit is turned off.
The provided text describes a 510(k) premarket notification for the VenaPro Vascular Therapy System, arguing for its substantial equivalence to a previously cleared predicate device (K133274). The document does not describe a study involving human readers or AI assistance, nor does it specify acceptance criteria for clinical performance. Instead, it focuses on non-clinical testing and a comparison of the device's technical characteristics with its predicate.
Therefore, many of the requested pieces of information are not present in the provided document.
Here's the information that can be extracted or inferred:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not specify quantitative acceptance criteria for clinical performance. Instead, it focuses on demonstrating equivalence to a predicate device through technical specifications and non-clinical testing. The "performance" reported is primarily that the subject device meets the same specifications, functions, and safety standards as the predicate.

7. Substantial Equivalence
As shown in the above table of comparison, the subject device in this submission has the identical performance and parameter to the predicate device in K133274. The updated and optimized circuit board in the subject device does not change any product performance. And the differences between the modified subject device and the original (predicate) device do not raise any new issues of safety or effectiveness.
The subject device is substantially equivalent to the predicate devices listed in function and operating principals to achieve identical results. The predicate device utilizes microprocessor controlled pumps to deliver approximately 50 mmHg of pressurized air to bladders that are attached to the patient's lower limbs, using a cycle time of approximately 60 seconds/leg. Each cycle consists of inflation of a bladder, followed by a rest period during which the bladder deflates and the limb relaxes without any compression.
{8}------------------------------------------------
Identical to the predicate device, the subject device has multiple audible and visual safety alarms built into the system, including low pressure alarms, low battery alarm and system malfunction overpressure safety alarm. In addition, the cuff is comprised of single bladder PVC chambers encased in a covering of soft, non-latex, non-woven medical fabric (a Polyester blend) or equivalent medical material for increased patient comfort and biocompatibility compliance. The microprocessor and pump units are powered by internal rechargeable batteries, and can be connected to the main AC power line (through the battery charger / AC adaptor) while in use, allowing uninterrupted prolonged service.
The subject device is designed for the same intended use as the predicated device. The comparison of the specifications demonstrates the functional equivalence of the products, concluding that the subject device is substantially equivalent to the predicate device.
8. Non-Clinical Tests Performed
Non-clinical tests were performed on the subject device in order to validate the design and to assure conformance with the following voluntary design standards in connection with medical device electrical safety, and electromagnetic compatibility.
- (a) ANSI AAMI ES60601-1 "Medical Electrical Equipment Part 1: General requirements for basic safety and essential performance (IEC 60601-1)".
- (b) IEC 60601-1-2 "Medical Electrical Equipment Part 1-2: General Requirements for Basic Safety and Essential Performance - Collateral standard: Electromagnetic Compatibility - Requirements and Tests".
- (c) IEC 60601-1-11 "Medical Electrical Equipment Part 1-11: General Requirements For Basic Safety And Essential Performance - Collateral Standard: Requirements For Medical Electrical Equipment And Medical Electrical Systems Used In The Home Healthcare Environment".
- (d) IEC 62133-2 "Secondary Cells And Batteries Containing Alkaline Or Other Non-Acid Electrolytes -Safety Requirements For Portable Secondary Cells, And For Batteries Made From Them, For Use In Portable Applications - Part 2: Lithium Systems".
In addition to the compliance of voluntary standards, bench tests have been performed on the physical requirements, electrical requirement, and performance requirement; the verification of software used in the subject device has been carried out according to the FDA Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices.
9. Conclusion
The tests and comparison performed demonstrate the subject device is substantially equivalent to the predicate device. Therefore, the subject device is as safe and effective as the predicate device that has been legally marketed in the United States.
