Sterile delivery
The device and the screwdriver have been gas-sterilized. Sterility is guaranteed only if
the blister and quality control seal have not been damaged.
Sterile packaging
The device and screwdriver are packaged in two separately sealed blisters. The inner
blister is also sterile on the outside so that it can be transferred in a sterile state during
implantation.
Single use only
The device and screwdriver are intended for single use only.
•
Do not use the device if the package is damaged.
•
The device must not be resterilized and reused.
Possible Complications
General information on medical complications
Complications for patients and device systems generally recognized among practitio-
ners also apply to BIOTRONIK devices.
•
Normal complications may include fluid accumulation within the device pocket,
infections, or tissue reactions. Primary sources of complication information include
current scientific and technological knowledge.
•
It is impossible to guarantee the efficacy of antitachycardia therapy, even if the
programs have proven successful during tests or subsequent electrophysiological
examinations. In rare cases the set parameters may become ineffective. It is
possible for therapies to induce or accelerate tachycardia and cause sustained
ventricular flutter or fibrillation.
Skeletal myopotentials
Bipolar sensing and control of sensitivity are adapted by the device to the rate range of
intrinsic events so that skeletal myopotentials are usually not recorded. Skeletal
myopotentials can nonetheless be classified as intrinsic events especially at very high
sensing sensitivity and, depending on the interference, may cause inhibition or anti-
arrhythmia therapy.
In the case of undesired myopotentials, the device switches to asynchronous pacing if
the interference rate is exceeded.
Possible technical failures
Technical failure of a device system cannot be entirely ruled out. Possible causes can
include the following:
•
Lead dislodgement, lead fracture
•
Insulation defects
•
Device component failures
•
Battery depletion
•
Interrupted telemetry
Electromagnetic interference (EMI)
Any device can be sensitive to interference if external signals are sensed as intrinsic
rhythm or if measurements prevent rate adaptation.
•
BIOTRONIK devices have been designed so that their susceptibility to EMI is
minimal.
•
Due to the intensity and variety of EMI, there is no guarantee for safety. It is
generally assumed that EMI produces only minor symptoms, if any, in patients.
•
Depending on the pacing mode and the type of interference, sources of interference
may lead to pulse inhibition or triggering, an increase in the sensor-dependent
pacing rate or asynchronous pacing.
•
Under unfavorable conditions, for example during therapeutic or diagnostic proce-
dures, interference sources may induce such a high level of energy into the pacing
system that the cardiac tissue surrounding the lead tip is damaged.
Device behavior in case of EMI
In case of electromagnetic interference, the device switches to asynchronous pacing
for as long as the interference rate is exceeded.
Static magnetic fields
The magnetic sensor in the device detects magnetic fields starting at a magnetic flux
density of approximately 1.5 mT. Magnetic fields below 1 mT do not affect the sensor.
