Hybrid system forming an active implantable medical device
First Claim
1. A system forming an active implantable medical device comprising:
- a subcutaneous autonomous unit, comprising;
a first seal body housing electronic circuitry and power supply means for the electronic circuitry; and
at least one lead for detecting and/or delivering therapy extending from said first seal body, such lead comprising at least one electrode; and
at least one intracorporeal autonomous leadless capsule suitable for implantation in or against a body and comprising;
a second seal body housing electronic circuitry and power supply means for these circuits;
anchoring means coupled to a wall of said second seal body; and
at least one electrode suitable for coming into direct contact with said second seal body,in which the subcutaneous autonomous unit and the leadless capsule each include transmitter/receiver means for intracorporeal mutual wireless communication, the subcutaneous autonomous unit operating as master and the leadless capsules operating as slaves under the control of the subcutaneous autonomous unit,and wherein the subcutaneous autonomous unit further comprises;
centralization means of the data transmitted by the leadless capsules, andmeans of communication with the outside, able to operate a remote transmission, to a remote device, of the data collected by the means of centralization of data,wherein the at least one detection and/or therapy delivery lead is a microlead comprising at least one microcable formed of an electrically conductive core cable connected to one pole of said electronic circuits, with an insulation layer surrounding the core cable and comprising at least a selectively exposed area formed in the insulation layer and for forming said electrode for detection and/or therapy delivery,the diameter of the microlead being at most 1 French (0.33 mm) in its distal region comprising said selectively exposed area; and
wherein the subcutaenous autonomous unit is a hybrid capsule whose volume is at most 1 cm3 and wherein;
the microlead is directly connected to the electronic circuits of the hybrid capsule,the at least one microlead extends said first seal body on one side thereof, andthe core cable of the microcable, or of each microcable, is directly connected to a respective pole of the electronic circuits of the hybrid capsule.

Abstract
A hybrid system forming an active implantable medical device includes a subcutaneous autonomous capsule and at least one intracorporeal autonomous leadless capsule. The subcutaneous capsule is a hybrid capsule having a seal body of dimensions comparable to those of a leadless capsule, but extended by a detection/stimulation microlead, without any intermediate connector. The leadless capsule includes a seal body, anchoring means in a wall of an organ and a detection/stimulation electrode. The hybrid capsule and the leadless capsules each include transmitter/receiver means for intracorporeal mutual wireless communication so as to constitute a network wherein the hybrid capsule is the master and leadless capsules are the slaves. The hybrid capsule further includes means for centralizing data transmitted by the leadless capsules and for exchanging data with remote external equipment.
