CAVT
Computer Assisted Vacuum Thrombectomy (CAVT™) is revolutionizing frontline interventional clot removal designed for speed, safety, and simplicity.

What is CAVT?
Computer Assisted Vacuum Thrombectomy (CAVT) is an advanced, minimally invasive procedure used to remove thrombus from veins and arteries, and for the treatment of pulmonary embolism (PE).
This technology leverages the power of microprocessors equipped with clot detection algorithms. These intelligent algorithms are designed to facilitate rapid recognition and removal of blood clots.
CAVT offers a more powerful and advanced alternative to analog methods such as open surgery, large-bore aspiration thrombectomy (LBAT), and catheter-directed thrombolysis (CDT).

Advancing Endovascular Care with Cutting-Edge Software
The core feature of CAVT technology is its refined algorithms, which detect the difference between thrombus and patent flow. These algorithms work together to automatically adjust the vacuum provided by the Penumbra ENGINE®.
The system seamlessly alternates between “Sampling Mode” and “Clot Detected Mode,” and provides physicians with audio-visual cues for a more intuitive experience.
This distinction allows for an immediate and clear response to the changing dynamics of the procedure, designed to minimize the risk of complications and optimize thrombus removal.

The Impact of CAVT1, a
Research shows that PE patients treated with CAVT experience shorter hospital stays and fewer complications compared to other treatment options. Including:
Shorter total hospital length of stay
25% - 35%
(statistically significant relative to all other modalities studied)
Lower composite complicationsb
3.4x
(statistically significant relative to other mechanical thrombectomy)
Higher rate of patients discharged to home
25% - 30%
(statistically significant relative to all other modalities studied)

Benefits of CAVT
Speed
CAVT microprocessors can automatically initiate Modulated Aspiration when faced with tough thrombus, allowing the system to ingest clot faster and rapidly restore blood flow.
Safety
Penumbra’s MaxID aspiration catheters are designed to have atraumatic and trackable profiles engineered to navigate delicate arteries, veins, and the complex pulmonary vasculature.
Simplicity
Penumbra’s CAVT portfolio streamlines and simplifies clot removal through intraprocedural audio-visual cues, and the ability to address a wide range of peripheral vessels.
CAVT Products
Penumbra’s CAVT platform harnesses advanced computer technology designed to enable rapid restoration of blood flow in cases such as acute limb ischemia, venous thrombus, and pulmonary embolism. The platform utilizes the Penumbra ENGINE Aspiration Source, which delivers nearly pure, continuous vacuum (-29 inHg or -98.2 kPa) to our catheters, enabling effective thrombus removal in a wide range of vessel sizes.
