Intended Use

The B&J MHP800 deep vein thrombosis prevention system is intended to be an easy to use portable system, prescribed by a physician, to help prevent the onset of DVT in patients by stimulating blood flow in the extremities (simulating muscle contractions). The device can be used in the home or clinical settings to: - Aid in the prevention of DVT; - Enhance blood circulation; - Diminish post-operative pain and swelling; - Reduce wound healing time; - Aid in the treatment of: stasis dermatitis, venous stasis ulcers, arterial and diabetic leg ulcers, chronic venous insufficiency and reduction of edema in the lower limbs; - As a prophylaxis for DVT by persons expecting to be stationary for long periods of time

Device Story

B&J MHP800 is a portable, non-invasive intermittent pneumatic compression system. It consists of a pump and limb sleeve assemblies. The pump inflates leg cuffs to a preset pressure of 45 mmHg for 12 seconds, followed by a 48-second deflation period, repeating this cycle once per minute. Powered by an internal rechargeable lithium battery, the device is designed for continuous operation in home or clinical settings. It is prescribed by physicians to stimulate blood flow, simulating muscle contractions to prevent DVT and manage associated venous conditions. The device provides mechanical prophylaxis, helping to reduce post-operative pain, swelling, and wound healing time. Patients or caregivers operate the device; the provider monitors clinical outcomes based on the device's therapeutic effect on circulation and edema.

Clinical Evidence

Bench testing only. No clinical data provided. Performance testing included system-level software validation, pressure accuracy, cycle time, bladder burst, and leak testing. Biocompatibility, electromagnetic compatibility, and electrical safety were also verified against predefined acceptance criteria.

Dear Fu Ailing:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.
