II pump is powered by an internal battery which lasts approximately
7 years before it will need to be replaced. Because the battery
is an integral part of the pump itself the entire pump needs
to be replaced. This replacement involves a small operation
requiring a brief hospital stay to replace with a new pump,
the catheter normally remains and does not need replacing.
The battery life is constantly
monitored by your medical team but as an added safeguard
there are a number of alarms relevant to the patient that
alert the medical team to the functioning of the pump, these
alarms beep softly and include:
Low battery alarm (alerts
when the battery needs to be replaced)
End-of-life battery indicator (predicts how many months of life remains)
Low reservoir alarm (alerts when the reservoir needs to be refilled)
Pump memory error (alerts if the pump has stopped functioning)
The pump has two
options in reservoir size, either 20 or 40 millilitres which
determines the thickness of the pump. The choice of size
is dependent on many clinical decisions that include the
size of the child and the refill frequency.
therapy was first licensed in the UK for spasticity of cerebral
origin (including CP) in 1996.
There have been
approximately 65,000 SynchroMed pump implants worldwide since
the launch of the first SynchroMed pump used to deliver a
variety of medications including ITB.
