Autonomous cardiac implant of the leadless capsule type, comprising an interface for external communication during transportation and storage

An autonomous cardiac implant of the leadless capsule type, comprising:

• a tubular body;
• surface electrodes carried by the tubular body;
• an energy harvesting module adapted to convert external stresses applied to the implant into electrical energy, comprising an inertial pendular unit including an elastically deformable element coupled to an inertial mass;
• a rechargeable battery adapted to be charged by the energy harvesting module, the battery being previously charged to an initial charge level;
• and
• an interface circuit adapted to selectively couple the surface electrodes to the rechargeable battery, comprising a switching circuit adapted to operate a switching between (i) a transport and storage configuration before implantation of the implant and (ii) a functional configuration after the implant has been implanted,
• wherein in the transport and storage configuration the surface electrodes are connected to a link coupling to an external source forming an electrical energy reserve, the external source being physically separated from the implant, and
• the interface circuit is adapted to receive a power supply from the external source and to release this power supply to the rechargeable battery, and
• wherein in the functional configuration, the surface electrodes are decoupled from the external source,
• wherein the implant further comprises at least one of:
• a data transmitter circuit adapted, in the transport and storage configuration, to send communication signals, via the surface electrodes, on the link coupling to the external source, and
• a data receiver circuit adapted, in the transport and storage configuration, to receive, via the surface electrodes, communication signals transmitted on the link coupling to the external source,
• and wherein a switch interposed between said external source and said link coupling to the external source is adapted to be controlled by a control signal for producing short cuts of a supply voltage of the power supply received by the capsule, whereby providing said communication signals.
