Various configurations of systems that employ leadless electrodes to provide pacing therapy are provided. In one example, a system that provides multiple sites for pacing of myocardium of a heart includes wireless pacing electrode assemblies that are implantable at sites proximate the myocardium using a percutaneous, transluminal, catheter delivery system. Also disclosed are various configurations of such systems, wireless electrode assemblies, and delivery catheters for delivering and implanting the electrode assemblies.

Leadless cardiac stimulation systems

Some embodiments of pacing systems employ wireless electrode assemblies to provide pacing therapy. The wireless electrode assemblies may wirelessly receive energy via an inductive coupling so as to provide electrical stimulation to the surrounding heart tissue. In certain embodiments, the wireless electrode assembly may include one or more biased tines that shift from a first position to a second position to secure the wireless electrode assembly into the inner wall of the heart chamber.

Cardiac stimulation system

A wireless electrostimulation system can comprise a wireless energy transmission source, and an implantable cardiovascular wireless electrostimulation node. A receiver circuit comprising an inductive antenna can be configured to capture magnetic energy to generate a tissue electrostimulation. A tissue electrostimulation circuit, coupled to the receiver circuit, can be configured to deliver energy captured by the receiver circuit as a tissue electrostimulation waveform. Delivery of tissue electrostimulation can be initiated by a therapy control unit.

Wireless tissue electrostimulation

A seed assembly for delivery to an interior of a heart includes an electrical stimulation circuit for delivering an electrical stimulus to cardiac tissue. A first electrode assembly is mechanically and electrically coupled to the seed assembly via a micro lead, the first electrode assembly configured to deliver the electrical stimulus generated by the electrical stimulation circuit to the cardiac tissue. The seed assembly and the first electrode assembly are sized and shaped to fit entirely within the heart.

Cardiac stimulation using intravascularly-deliverable electrode assemblies

Systems for nerve and tissue modulation are disclosed. An illustrative system may include an intravascular nerve modulation system including a catheter shaft, a first flexible mount, and a cylindrical ablation transducer. The ablation transducer may be affixed to the catheter shaft through the flexible mount to allow an infusion fluid to pass through a lumen of the transducer. Another illustrative system may include an intravascular nerve modulation system including an expandable basket for centering an ablation tra7nsducer within a lumen.
