Foley Catheter

Foley Catheter: The Evolution Is Here

Foley catheters have been an industry standard for over 75 years now. Since it’s breakthrough design in 1937, not much has changed from the original designs of Frederick Foley.

The Foley catheter has been, until recently, the only real tangible choice for medical professionals across the world to use to deal with a massive variety of urinary issues, both in and out of medical centers.

To fully understand how the Duette™ dual balloon catheter is the next step in the evolution of the Foley catheter, you must first understand it’s predecessors, the inherent problems they cause, and how these issues are costing the health care industry millions in treatments to combat the complications that arise from using the industry standard.

The Foley Catheter And Common Terms:

You may have heard the term “indwelling catheter” and essentially that is exactly what the Foley catheter is, whereby the device is inserted into the bladder via the urethra and remains in the bladder for an extended period of time.

The device itself is a simple enough concept to understand; a small flexible tube, usually made from rubber or silicone, is inserted into the the urethra passing into the bladder where the catheter will drain the bladder of urine. The real breakthrough with this type of design is the inflatable balloon, which allows the device to be secured in the bladder by filling it with sterile water.

The external part of the catheter has 2 tubes; a urine drainage tube along with a balloon port that is used to fill or empty the balloon using a syringe during insertion and removal of the catheter. There are also 2 other variants available which are the Coude catheter and the three-way catheter.

Coude Catheter – the Coude catheter is traditionally used in older patients, and incorporates a rounded tip also known as an “elbowed” tip. This is helpful in dealing with insertion issues, such as navigating a large prostate.

3 way catheter – Has 3 lumins instead of 2 so that medications can be instilled within the bladder without complication. The 3 way catheter allows for urine to drain from the bladder, while also allowing a medical professional to flush the bladder with medication to help heal infections or blood clots.

Although there has been much research into dealing with the side effects and associated risks of using a catheter, the Foley catheter design has remained practically unchanged until the introduction of the Duette catheter. Not only does the Duette™ catheter have a balloon to hold the catheter in place, but it also has a balloon around the tip of the catheter which allows the bladder to be prevented from catheter associated risks, as well as, heal from side effects caused by using a standard Foley catheter.

Inherent Problems and Side Effects:

Over the years, there has been great headway in understanding and reducing the side effects caused by indwelling catheters, but unfortunately the infection rates among users is still staggering. The chances of contracting a CAUTI (catheter associated urinary tract infection) in most modern hospitals is a 1 out of every 10 patients, with the highest risk being applied to indwelling catheters. This isn’t the only factor patients have to deal with when it comes to associated risks of using an indwelling catheter. Other risks include:

Bladder spasms – This happens when the catheter irritates the bladder, which in return causes the bladder to spasm. In cases of chronic bladder irritation, there is also a greater risk of bladder cancer. Bladder spasms can also occur when a catheter becomes clogged.

Urine blockage flow- If there is no urine in the urine drainage bag, then this is a good sign that the catheter has become blocked or clogged. This can happen due to blood or sediment building up a mass that blocks urine from moving through the catheter. Bladder spasms can often occur from a clogged catheter as the body’s way of letting a person know that something is not right in the bladder.

Hematuria – Hematuria is when red blood cells are found in the urine. There are many reasons as to why hematuria may occur, but one of the biggest contributing factors is from thetrauma that is caused by the tip of the catheter damaging the urethra and the bladder wall. This is unfortunately a reoccurring problem that happens with Foley catheters. However, the Duette™ catheter has been designed to help the bladder avoid trauma caused by catheter tips by providing a cushioning balloon around the tip.

Cystitis – Cystitis is inflammation of the bladder and can be caused by internal trauma from a catheter. It is most commonly found when a patient has been diagnosed with a urinary tract infection.

These are only a few examples of the major problems that patients face and is the reason why the industry as a whole is in great need of a viable alternative.

Although there have been slight alterations in the design over the years, such as reshaping the tip (to prevent higher rates of urethral and bladder trauma), using different materials, and the introduction of anti-bacterial coatings in an effort to curb the high instances of infections such as CAUTIs (catheter-related urinary tract infections), in truth these developments have largely been ineffective in resolving the very severe risks traditional catheters pose to patients all over the world. This is not even mentioning the burden health services face in both time and expense.

 Are there any other options?

Yes, there are other options besides the Foley catheter. The Duette™ Dual Balloon catheter by Poiesis Medical has taken a different approach in resolving the many issues created by the traditional Foley catheter and for the first time in over 75 years, a complete overhaul of the design and mechanism has been achieved, resulting in the creation of a catheter that is truly the next step in its evolution. The Duette™ catheter has unique designs that overcome the flaws of the traditional Foley catheter, such as a second balloon around the catheter tip which helps control infections and prevent trauma to the bladder, drainage eyes positioned between the two balloons to help prevent aspiration damage to the bladder’s lining, and it can be inserted exactly the same with none or minimal assistance. Unlike the Foley catheter, the Duette™ helps reduce Cystitis  chronic irritation of the bladder, CAUTI (catheter-associated urinary tract infection), blockage of urine, penetration and perforation of the bladder wall, Hematuria, and patient pain levels during catheterization. The Duette™ catheter is changing the evolution of what used to be the standard catheter. The Duette™ catheter is the new catheter that medical professionals and patients around the world are now requesting when it comes to managing urinary issues and will soon replace the industry standard.
