About Silicon Sensors for
use in Catheters
To reduce the amount of trauma during medical procedures,
so-called minimally invasive procedures are being used. In
vascular interventions, catheters are used in the blood vessels.
In order to Increase the amount of information a physician has
available during these interventions, sensors are needed. To this
end, a multiple parameter sensor to measure blood pressure, flow,
oxygen saturation and temperature, and a sensor to determine the
age of blood clots using colour are developed. In addition, a
system to reduce the amount of ionising radiation needed during
the positioning of catheters is developed. The special environment
puts high demands on the packaging. It needs to protect the sensor
from the body, the body from the sensor but allow the parameter to
be measured access to the sensor. To overcome the uncertain
positioning of the sensor within the vessel, a special sensor
catheter needs to be designed.
