Fogarty arterial embolectomy catheter is a device developed in 1961 by Dr. Thomas J. Fogarty to remove fresh emboli in the arterial system. [1] It consists of a hollow tube with an inflatable balloon attached to its tip. The catheter is inserted into the blood vessel through a clot.
Surgical embolectomy for massive pulmonary embolism (PE) has become a rare procedure and is often viewed as a last resort. Thrombolytic therapy has become the treatment of choice. [1] Surgical or catheter embolectomy is a procedure performed in patients with pulmonary embolism, which is a blockage of an artery in the lung caused by a blood clot.
In 1969, Fogarty patented his device, and Edwards Life Sciences from Irvine, California, was assigned the patent to begin manufacturing the Fogarty embolectomy catheter. Because of the decreased risk associated with the device, Fogarty's balloon catheter became the industry standard and remains the most widely used catheter for blood-clot removal.

Surgery is often recommended in those with Rutherford Class 2b or greater, as blood flow is generally restored much more quickly. The primary surgical intervention in acute limb ischaemia is emergency embolectomy using a Fogarty Catheter, providing the limb is still viable within the 4-6h timeframe. [25]

A system of coaxial catheters is pushed inside the arterial circulation, usually through a percutaneous access to the right femoral artery. A microcatheter is finally positioned beyond the occluded segment and a stent-retriever is deployed to catch the thrombus; finally, the stent is pulled out from the artery, usually under continuous ...
By changing the diagnostic catheter to a guiding catheter, physicians can also pass a variety of instruments through the catheter and into the artery to a lesion site. The most commonly used are 0.014-inch-diameter (0.36 mm) guide wires and the balloon dilation catheters. [citation needed]
