Why might I need patent foramen ovale transcatheter repair?
Most PFOs do not cause any symptoms and do not need any treatment. But sometimes PFOs can lead to complications. The most significant of these is stroke. Stroke can result from a traveling blood clot that blocks a blood vessel in the brain. PFOs do not cause most strokes, but having a PFO may slightly increase the risk for stroke in some people.
How does a transcatheter repair work?
But in most people, it closes soon after birth. During transcatheter repair, a healthcare provider inserts a device that can plug up the PFO. This device attaches to the end of a long, flexible tube called a catheter. The healthcare provider inserts the catheter through a blood vessel in the groin and guides it to the PFO.

Is transcatheter repair more invasive than surgical repair?
A transcatheter repair is less invasive than a surgical repair. You usually recover more quickly. Your healthcare provider might be less likely to recommend this treatment if you need surgical repair for another heart problem in addition to the PFO. Ask your healthcare provider what treatment is best for you.
What is a catheter?
A catheter for insertion into a cavity, duct, or vessel to permit injection or withdrawal of fluids or to establish patency of a passageway comprises an elongated tubular catheter body having a distal end and a proximal end and an outer diameter, a drainage lumen extending through the catheter body from the distal end to the proximal end, the drainage lumen communicating with an opening in the catheter body at the distal end of the catheter body, an inflation lumen formed in the catheter body, and one or more of the following: a) inflatable tube sections disposed on the catheter body at the distal end of the catheter body for securing the distal end of the catheter body in a desired location when the tube sections are inflated, b) a valve connected to the inflation lumen for permitting backflow of the inflation fluid from the inflation lumen through the valve when a pre-set pressure value is reached, and c) a hollow reservoir for holding a pre-determined volume of inflation fluid.
Why is Foley catheter pooling?
This urine pooling problem occurs because good drainage of urine from a patient's bladder is often difficult or impossible using a Foley catheter. Due to the structure of the Foley catheter, the opening to the drainage lumen is positioned above or away from the entrance to the patient's urethra when the distal end of the catheter body is retained in a patient's bladder since the opening to the drainage lumen is positioned between the retaining balloon and the distal end of the catheter body. Similarly, due to the structure of the Foley catheter, properly irrigating a patient's bladder using a Foley catheter is often difficult.
What is the preferred valve 29?
Since the preferred valve 29permits backflow when a pre-set pressure release level is reached, the pre-set pressure release level being at or just below the amount of pressure created in the inflation lumen 25and the tube sections 23when attempting to remove the inventive catheter 11from a person's bladder while the tube sections 23of the invention are inflated, the risk of injury to a person's urethra associated with accidental removal of a Foley catheter from a person's bladder while the balloon of the Foley catheter is inflated is eliminated with the inventive catheter 11.
What is the valve in a catheter 11?
As shown in FIGS. 1 and 2, catheter 11is provided with a valve 29positioned at an inflation port 31formed in the catheter body 13through which inflation fluid 24is passed into the inflation lumen 25. The valve 29is constructed to permit insertion of inflation fluid 24into the inflation lumen 25and subsequently to the inflatable tube sections 23and for preventing backflow of the inflation fluid 24from the inflation lumen 25during normal operation of the catheter 11. An exemplary valve 29is that made by Bard, but other companies make such valves.
How does Foley catheter work?
The Foley catheter is provided with an inflatable retaining balloon near the distal end of the catheter body, located short of the opening to the drainage lumen, for securing the distal end of the catheter body in the patient's bladder. The retaining balloon is filled by injecting fluid with a syringe through a small filling channel. The fluid is retained by a valve which closes after removal of the syringe.
Why is the catheter tip smooth?
Another object of the invention is to provide a catheter having a smooth tip at its distal end to avoid irritation of a patient's bladder as often happens due to the structure at the distal end of a Foley catheter and a Mallacote catheter.
Where is catheter 11 inserted?
In use, catheter 11is inserted into a cavity, duct, or vessel. For example, if the catheter 11is being used as a urinary catheter, the catheter body 13is inserted through a person's urethra and into a person's bladder such that the distal end 15of the catheter body 13, along with the tube sections 23, are located in the person's bladder and the main portion of the catheter body 13is located in the person's urethra. Then, inflation fluid 24is inserted from a syringe 37into the inflation lumen 25through the port 31to the tube sections 23to inflate the tube sections 23, thereby securing the distal end 15of the catheter 11in place in the persons'bladder.
What is a catheter retaining device?
What is more, the catheter retaining means is adapted to provide little resistance in the event that the patient should suddenly and forceably jerk the catheter out of his bladder. That is to say, the retaining device will automatically conform to the dimensions of the urethra and thereby not oppose a removal of the catheter. In this manner, the urinary tract of the patient will be subjected to minimal trauma and experience less damage.
What is improved urinary catheter?
An improved urinary catheter having a unique, low volume device by which to retain the catheter within the bladder, so that urine can be removed therefrom. The retaining device consumes less volume in the bladder than that which would ordinarily be consumed by a conventional Foley-style balloon, whereby both the frequency and severity ...
How to tether balloon 34 to catheter 1?
The balloon 34 is preferably tethered to the catheter 1 by means of a narrow flexible band 46. Accordingly, should the edge 36 of the balloon 34 be removed from its catch 38, whereby to completely detach the balloon from the catheter 1, the balloon will still remain connected to the catheter by the band 46.
How do retaining fingers work in a catheter?
The fingers are seated upon the bladder to retain the catheter therewithin. The fingers assume a torroidal (rather than a spherical) configuration, but consume a much smaller volume within the bladder than a Foley-style balloon. Urine may then be removed from the bladder in the normal fashion through the urine inlet aperture 4 and urine passage 2. However, should the patient suddenly attempt to pull out the catheter with the retaining fingers advanced outwardly thereof, the retaining fingers will be correspondingly pulled toward the bottom of the bladder. By virtue of the resilient nature thereof, the normally coiled fingers 56 will extend proximately (in the direction shown in FIG. 11) when the catheter is pulled through the patient's urethra. Hence, the retaining fingers 52 automatically yield or straighten in response to the force which is exerted thereon by the urethra, whereby to offer little resistance to the removal of the catheter. Thus, the catheter 1 of FIGS. 7 and 8 may be pulled completely through the patient's urinary tract without imparting significant damage.
Does a retaining device reduce bladder spasms?
The retaining device consumes less volume in the bladder than that which would ordinarily be consumed by a conventional Foley-style balloon, whereby both the frequency and severity of urinary bladder spasms, which are induced by pressure against the trigonal area of the bladder, can be reduced.
Does Foley catheter occlude urine?
What is still more, the conventional Foley catheter has no means to selectively occlude the central urine passage thereof. Therefore, that is no way to temporarily interrupt the flow of urine through the catheter. Likewise, there is no way to inhibit to ascent of infection up the catheter and into the bladder.
