SonRtip is the only atrial pacing lead featuring an embedded hermetically-sealed micro-accelerometer.
The SonRtip sensor is a piezoceramic transducer loaded by a platinum/iridium seismic mass, converting flexural stresses to electricity
A micro spring integrated into the sensor increases sensitivity while providing additional protection and shock resistance
The sensor signal is amplified and transmitted to the SonR CRT-D device through a micro electronic circuit to ensure long-term signal integrity
