Modular implantable medical device

An implantable medical device comprising:

• a first module that includes control electronics housed within a first housing;
• a second module that includes a power source that provides power to the first module housed within a second housing;
• and
• an interconnect member that flexibly couples the first and second modules.

An implantable medical device comprising:

• a first module that includes control electronics housed within a first housing;
• a second module that includes a power source that provides power to the first module housed within a second housing;
• and
• a hermetic interconnect member that flexibly couples the first and second modules, wherein the interconnect member is flexible in a plurality of directions and allows the first and second modules to have a plurality of degrees of freedom of movement relative to each other.

An implantable medical device comprising:

• a first module comprising control electronics and a therapy delivery circuit housed within a first housing, wherein the control electronics control delivery of stimulation by the therapy delivery circuit;
• a second module comprising a power source within a second housing that provides power to the control electronics and the therapy delivery circuit;
• an interconnect member that flexibly couples the first and second modules and includes a conductor for delivery power from the power source to the control electronics and the therapy delivery circuit;
• and
• a flexible overmold that at least partially encapsulates the first and second housings.

An implantable medical device comprising:

• control electronics and a rechargeable power source that provides power for the control electronics within a first housing;
• a recharge coil within a second housing that inductively receives energy to recharge the power source;
• and
• a flexible tether member that connects the first and second housings.
