By modifying the material or adjusting the way catheters are manufactured, it is possible to tailor catheters for cardiovascular, urological, gastrointestinal, neurovascular, and ophthalmic applications. Catheters can be inserted into a body cavity, duct, or vessel.
Functionally, they allow drainage, administration of fluids or gases, access by surgical instruments, and also perform a wide variety of other tasks depending on the type of catheter. A physician is required to administer this procedure. The earliest invention of the flexible catheter was during the 18th century. 1752 when his brother John suffered from bladder stones. Franklin’s catheter was made of metal with segments hinged together with a wire enclosed to provide rigidity during insertion. Francesco Roncelli-Pardino from 1720 as the inventor of a flexible catheter.
The procedure involved entering a horse’s ventricles via the jugular vein and carotid artery. This appears to be an earlier and modern application of the catheter because this catheter approach technique is still performed by neurosurgeons, cardiologists, and cardiothoracic surgeons. Prior to his invention, red rubber tubes were used, sterilized, and then re-used, which had a high risk of infection and thus often led to the spread of disease. As a result, Mr Sheridan is credited with saving thousands of lives. In the early 1900s, a Dubliner named Walsh and a famous Scottish urinologist called Norman Gibbon teamed together to create the standard catheter used in hospitals today. Named after the two creators, it was called the Gibbon-Walsh catheter.
The Gibbon and the Walsh catheters have been described and their advantages over other catheters shown. The Gibbon catheter has largely obviated the necessity of performing emergency prostatectomy. A simple procedure such as dilatation of the urethra and passage of a Gibbon catheter often causes the fistula to close. This catheter is also of use in the treatment of urethral stricture and, as a temporary measure, in the treatment of retention of urine caused by carcinoma of the prostate.
