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.
A catheter transports the stent to the weakened blood vessel, and once the balloon is inflated, the stent expands to the size of the blood vessel, and blood flows normally. Fogarty's other inventions include Fogarty surgical clips and clamps, which are used by cardiac and vascular surgeons to temporarily occlude vessels during surgery.
Once access to a blocked sinus is confirmed, a balloon catheter is advanced over the guide wire and positioned in the blocked sinus opening for inflation. The balloon is inflated. The entire procedure takes around 31 minutes and if the procedure is successful, the sinus will remain open after the balloon is deflated and removed for up to 24 months.
Nasal surgery is a specialty including the removal of nasal obstruction that cannot be achieved by medication and nasal reconstruction. Currently, it comprises four approaches, namely rhinoplasty, septoplasty, sinus surgery, and turbinoplasty, targeted at different sections of the nasal cavity in the order of their external to internal positions.
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 ...
Balloon Eustachian tuboplasty (BET) [1] is a minimally invasive procedure for the causal treatment of Eustachian tube dysfunction (ETD), an often-chronic disorder in which the regulation of middle ear pressure and the removal of secretions are impaired. The dysfunction often causes significant discomfort in affected patients and can trigger ...

Others can be treated by inserting a small catheter through a hole drilled through the skull and sucking out the hematoma. [citation needed] Large or symptomatic hematomas require a craniotomy. A surgeon opens the skull and then the dura mater; removes the clot with suction or irrigation; and identifies and controls sites of bleeding.
