Assignee: SORIN CRM SAS
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. An implantable medical system for measuring at least one physiological parameter, the system comprising:
a first implantable medical device provided with a dipole transmitter, the dipole transmitter being formed of two electrodes connected to a generator and being configured to transmit an electrical signal;
a second implantable medical device distinct from the first implantable medical device and provided with a dipole receiver, the dipole receiver being formed of two additional electrodes, each one being distinct from the electrodes of the dipole transmitter, the dipole receiver being configured to collect the electrical signal transmitted by means of the dipole transmitter;
a detector configured to capture an electrocardiogram or an electrogram of a patient's heart;
an analysis module comprising at least one amplifier, an envelope detector, an analogue-to-digital converter, and a processor configured to:
process the electrical signal captured by the dipole receiver;
compare and correlate the processed electrical signal to an acoustic signal representative of sounds of the patient's heart; and
associate the correlated electrical signal and the electrocardiogram or the electrogram to determine therefrom a parameter representative of a pre-ejection period.
