Abstract:
1. A leadless implantable medical device (IMD) comprising: a pulse generator configured to provide stimulation energy for delivery to a tissue of interest; a power supply; a memory storing programmable instructions; a processor communicatively coupled to the memory, the processor responsive to the programmable instructions to control operation of the leadless IMD; an electrode configured to be securely affixed to the tissue of interest; a housing retaining the pulse generator, the power supply, the memory, and the processor, the housing including first and second body portions mated to one another at a detachable interface, wherein the detachable interface includes a core positioned at and extending outward from a distal end of the first body portion, the second body portion including an outer wall surrounding a cavity open to an opening at a proximal end of the second body portion, the core being shaped and dimensioned to fit within the cavity when loaded through the opening at the proximal end and wherein the electrode is coupled to the second body portion; and wherein the core includes a first inductive coil, the second body portion including a second inductive coil at least partially extending about the outer wall around the cavity, the first and second inductive coils being positioned concentric with one another when the first and second body portions are mated to one another, such that the first and second inductive coils interact to inductively convey at least one of stimulation energy or sensed signals therebetween forming an energy transfer component when the first and second body portions are mated to one another.
