"We initiated a position in Penumbra, Inc. (NYSE:PEN), a leading manufacturer of medical devices that remove blood clots from veins and arteries. Physicians use the company’s devices to treat pulmonary embolism (PE), deep vein thrombosis (DVT), acute limb ischemia, ischemic stroke, coronary disease, and other conditions. Penumbra’s devices, which are called mechanical thrombectomy devices, use computer algorithms to modulate the aspiration power depending on if a clot is detected and to control a separate valve that injects saline to reduce friction between the clot and catheter. This enables a differentiated device profile that maximizes clot removal with speed while decreasing risk of blood loss.
