Abstract
A sensor arrangement for controlling an implantable device, such as a heart pacemaker, has a number of individual sensors connected to an evaluation circuit through a catheter having at least two leads. The sensors are respectively activated in chronological succession by a shared control circuit, with both the sensors and the control circuit being arranged in the catheter. The corresponding measured signals are transmitted via the same leads, and also being offset chronologically. The arrangement permits a number of sensors to be connected to a catheter while maintaining only two lines in the catheter, so that the flexibility and reliability of the catheter, which are best with the fewest possible leads, remain unimpaired.
