Abstract
Apparatus, system, and method that include a pacing apparatus having a stent electrode through which pulses of electrical current can be delivered. Stent electrodes receive energy for generating the electrical current from a variety of sources. Sources include from one or more induction coils that can form at least a portion of the stent. Sources can also include an implantable pulse generator coupled to a lead through which pulses of the electrical current are supplied to the stent electrodes.
Claims14
An apparatus, comprising:
- an intravascularly-deliverable wireless stent electrode assembly comprising:
- an expandable mechanical structure;
- a plurality of at least partially overlapping induction coils attached to the expandable mechanical structure, and electrically insulated from the expandable mechanical structure, and from each other, each induction coil including an elongate body positioned along a long axis of the stent and configured to wirelessly receive magnetically-coupled energy;
- one or more electrostimulation electrodes electrically configured to deliver at least some of the received magnetically-coupled energy as an electrostimulation to one or more tissue sites;
- wherein the plurality of induction coils are deformable and configured to open when the mechanical structure is expanded;
- wherein at least two of the plurality of induction coils are positioned at least partially orthogonally relative to each other;
- and
- wherein each elongate body includes a laminar construction and is configured to be electrically insulated from one or more at least partially overlapping adjacent laminae, and electrically insulated from the expandable mechanical structure.
