Probe for cardiac pacemaker
First Claim
1. A probe for a cardiac pacemaker comprising a heart signal sensor susceptible of applying pacing signals, a catheter having a distal end disposed between said sensor and the pacemaker and a flexible cord connected to said sensor and said catheter, and a semi-rigid attachment having a first end connected to the catheter and a second end for attachment to a cardiac wall, wherein the sensor is united with the catheter distal end for attachment to a cardiac wall and after said attachment the catheter distal end is disunited from said sensor and maintained at a distance from said sensor with the catheter connected to said sensor by the flexible cord and connected to the cardiac wall by the semi-rigid attachment so as not to apply any mechanical stress on said sensor.

Abstract
A heart signal sensor 11 is connected by a flexible cord 13 to a catheter 17. The sensor 11 and the catheter 17 are attached to install the sensor in the cardiac wall, and thereafter are disunited and separately attached to the cardiac wall 1. The sensor is attached to the cardiac wall by claws projecting from the sensor surface, and may be installed by rotating or by deformation of the sensor.
