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. The balloon is then inflated to extract the clot from the ...
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.
Catheter embolectomy is also used for aspiration embolectomy, where the thrombus is removed by suction rather than pushing with a balloon. [8] It is a rapid and effective way of removing thrombi in thromboembolic occlusions of the limb arteries below the inguinal ligament, [8] as in leg infarction.
A balloon catheter is a type of "soft" catheter with an inflatable "balloon" at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body. The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed.
The surgeon Dr. Thomas J. Fogarty invented a balloon catheter, designed to remove clots from occluded vessels, which was used as the eventual model to do endovascular angioplasty. Further development of the field has occurred via joint efforts between interventional radiology , vascular surgery, and interventional cardiology .
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.
