How It Works


About PleuraFlow Active Clearance Technology

The PleuraFlow® Active Clearance Technology (ACT) System is inserted between the chest tube and the drainage canister tubing. PleuraFlow® ACT uses a clearance loop that rests at the end of the chest tube inside the patient. When indicated, the clearance loop is manipulated using a proprietary magnetically coupled handle to enable clinicians to break up and clear obstructive clots without compromising the sterile environment inside the tube.


The PleuraFlow ACT system is packaged with silicone chest tubes that are specifically calibrated for use with PleuraFlow ACT. The chest tubes are inserted during surgery and attached to the PleuraFlow ACT to enable active clearance of clot obstructions postoperatively.

Cost Effective

PleuraFlow ACT is priced for routine use. Adoption of PleuraFlow ACT may save facilities money by standardizing chest tube management protocols and by decreasing the occurrence of Retained Blood Complications.


Using PleuraFlow ACT has been found to be intuitive and easy to use. Its award winning design fuses function with ergonomics to create a robust instrument proven to improve postoperative blood evacuation.


PleuraFlow ACT enables active clearance of chest tube obstructions to maximize evacuation capacity. Reliable evacuation capacity may enable surgeons to use smaller and fewer tubes, decreasing the surgical footprint and potentially reducing patient discomfort.

ClearFlow's PleuraFlow® Active Clearance Technology and many of its features are protected by a comprehensive family of both US and foreign patents and patent applications in major markets throughout the world, including Canada, Australia and the European Community. In the United States, PleuraFlow® products are protected by US Patent Nos. 7,854,728, 7,951,243, 8,246,752, 8,048,233 and 8,388,759. The PleuraFlow® product is the first device of its kind to effectively and reproducibly clear obstructing material from chest tubes without compromising the sterile field, and thus patient recovery. It is the only FDA 510(k) cleared device of its kind for this indication. ClearFlow's patent portfolio has been tailored not only to protect this product, but also to provide protection around this new market segment thus presenting a barrier to entry for competing products.
