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.
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.
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.
Typically this is done by inserting a catheter with an inflatable balloon attached to its tip into an artery, passing the catheter tip beyond the clot, inflating the balloon, and removing the clot by withdrawing the catheter. The catheter is called Fogarty, named after its inventor Thomas J. Fogarty. [citation needed]

Pigtail catheter is a non-selective catheter with multiple side holes that can deliver large volumes of contrast into a blood vessel for imaging purposes. [29] Cobra catheter is a selective catheter used to catheterise downgoing vessels in the abdomen. Cobra catheters move forward by pushing and are removed by pulling. [30]
For guidance regarding catheter positions during the examination, the physician mostly relies on detailed knowledge of internal anatomy, guide wire and catheter behavior and intermittently, briefly uses fluoroscopy and a low X-ray dose to visualize when needed. This is done without saving recordings of these brief looks.
A snare catheter is inserted using the Seldinger technique under fluoroscopic guidance. The snare wire is advanced under direct visualization and flowered open. The object being retrieved is captured within the loops of snare, and retrieved with the snare wire and catheter, being carried out of the body at the tip of the catheter.
