Dual Balloon Catheter

The Dual Balloon, Twin Balloon and Double Balloon Catheter

As you may already know, the traditional Foley catheters have relied on one single inflatable balloon, which is filled with sterile water and helps keep the catheter device in place while it is stationed in a patient's bladder. This design has remained practically unchanged for generations since the first Foley catheter was invented by Frederick Foley. The Foley catheter was a great invention to help empty urine from the bladder, but there were many problems with the Foley catheter that have remained unresolved, until now.

This is set to change with the introduction of the Duettedual balloon catheter. The Duette™ dual balloon catheter was designed to overcome the shortcomings of the Foley catheter and therefore help improve a patient's health and reduce healthcare costs by lowering readmission rates to medical facilities. The Duette™ twin balloon catheter will help to remove a lot of the inherent problems associated with the single balloon design, such as bladder wall trauma due to an uncushioned tip and obstruction of the urinary drainage eye, where the side of the bladder literally is sucked into the drainage hole causing tremendous damage. The invention of the Duette™ catheter is bringing the changes to the standard Foley catheter that have been needed for many generations. The Duette™ is the solution to trauma caused from using Foley catheters.

With a Dual balloon system, also referred to as “twin balloon catheter” and “double balloon catheter”, all that is set to change with the introduction of a second sterile balloon giving a two fold protection against the trauma risks associated with the bladder's defensive lining. This second balloon surrounds the catheter's tip providing increased comfort for the patient, as well as, comprehensive infection control. The dual balloon system design was created to help cut down on the instances of CAUTI (catheter associated urinary tract infection) by protecting the bladder wall and allowing the bladder wall to heal from previous damage resulting from the use of a standard Foley catheter.

An uncushioned tip, such as on the standard Foley catheter, has been replaced with a subsumed tip meaning there are no longer any problems with extensive friction to the bladder wall or even in severe cases, the tip becoming embedded in the lining causing even greater trauma. The second balloon is inflated around the tip of the catheter to provide a cushioning comfort and protect the bladder wall from damage, as well as, to help the bladder to heal from existing damage. The second balloon around the tip of the Duette™ catheter will also help reduce bladder spasms.

Another exciting feature to the Duettedouble balloon catheter is that the drainage eye has also been moved and placed in between the two balloons, completely removing the chances of aspiration commonly associated with the typical Foley catheter design.
