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.
Numerous sequel applications of Fogarty's catheter came about. The first balloon angioplasty, for example, was performed with a Fogarty catheter in 1965, and has led to over six hundred fifty thousand such operations per year. Fogarty has also modified his catheter to less invasive biopsy techniques.
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.
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]
A deflated balloon attached to a catheter (a balloon catheter) is passed over a guide-wire into the narrowed vessel and then inflated to a fixed size. [1] The balloon forces expansion of the blood vessel and the surrounding muscular wall, allowing an improved blood flow. [1]
Mechanical methods of injecting the thrombolytic compounds have improved with the introduction of pulsed spray catheters—which allow for a greater opportunity for patients to avoid surgery. [ 21 ] [ 22 ] Pharmacological thrombolysis requires a catheter to be inserted into the affected area, attached to the catheter is often a wire with holes ...
