Do not use a second drug-coated balloon at the same treatment site. Additional APERTO OTW balloon catheter
can be used to treat the lesion longer than the maximum balloon length available under the following
circumstances:
– each individual segment should be treated only once with a drug-coated balloon
– try to minimalize overlapping of treated segment
– treat each segment with a new PTA balloon
Overlapping of consecutively placed balloons with a treated segment should be avoided by precisely
angiographically positioned catheter, using the marker bands.
In order to eliminate as far as possible the balloon rupturing during use, the Rated Burst Pressure (RBP) must
NEVER BE EXCEEDED.
PREPARATION OF THE CATHETER
First of all, it is very important to check that the packaging is neither damaged nor opened before use.
The catheter and balloon in the deated state contain small amounts of air that must be eliminated before use.
Replace the air in the balloon, the balloon lumen and the central lumen with liquid before the catheter is used. The
following steps should be taken:
• Flush out the guidewire lumen with heparinised saline solution.
• Attach a syringe partially lled with a sterile mixture of saline solution and contrast medium to the balloon tube.
• Remove the balloon protective sleeve.
• Whilst the syringe and balloon are held down, draw the air out of the balloon into the syringe. Repeat until there
is absolutely no air left in the balloon. Repeat this process several times if necessary.
• Release the plunger and allow the saline to ll the folded balloon. DO NOT inate the balloon.
• Repeat the two last steps until all air is removed from the balloon catheter.
• Replace the syringe with a dilatation syringe and a manometer that have been prepared beforehand, i.e. partially
lled with saline solution.
• Draw the saline solution out of the catheter into the dilatation syringe
CATHETER INSERTION
The APERTO OTW is introduced percutaneously via a surgical cut or through an appropriate introducer sheath.
Use of an introducer sheath is generally recommended.
Under uoroscopic control the balloon should be pushed through the appropriate sheath over the guidewire and
positioned at the lesion to be dilated.
The recommended balloon ination and dilatation time is 90 sec.
CATHETER REMOVAL
APERTO OTW is removed after PTA over the positioned guidewire and through the introducer sheath. As the
balloon may have been dilated several times, there may be some resistance when it is removed.
STORAGE
• Store at controlled room temperature in a dry, cool and dark place.
• Use the catheter before to its “Use By” date printed on the package label.
• Do not use the catheter if the packaging is opened or damaged.
• Do not expose the catheters to organic solvents, ionising radiation or ultraviolet light.
STERILISATION
This catheter has been sterilized with ethylene oxide gas. It will remain sterile for as long as the packaging remains
unopened and undamaged.
Warning: For single patient use only. Do not reuse, reprocess or resterilize. Reuse, reprocessing or
resterilization may compromise the structural integrity of the device and/or lead to device failure which,
in turn, may result in patient injury, illness or death. Reuse, reprocessing or resterilization may also create
a risk of contamination of the device and/or cause patient infection or cross-infection, including, but not
limited to, the transmission of infectious disease from one patient to another. Contamination of the device
may lead to injury, illness or death of the patient.
