Abstract
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.
Claims20
A method of providing pacing therapy to a heart of a patient, comprising:
- implanting a wired lead extending from a pulse generator within the patient;
- advancing a wireless electrode assembly within a lumen of a delivery catheter into a chamber of the heart, the wireless electrode assembly including:
- a body having a distal end region extending to a distal end of the body and a proximal end region extending to a proximal end of the body;
- a first electrode secured to the distal end of the distal end region of the body;
- a second electrode disposed on the proximal end region of the body;
- and
- a tissue fixation member comprising a tine including a base, a tip and a medial portion extending therebetween, wherein the base is secured to the body between the first electrode and the second electrode;
- deploying the wireless electrode assembly out of the lumen of the delivery catheter by moving an actuation member longitudinally relative to the delivery catheter within the lumen;
- providing electrical stimulation to the heart with the wireless electrode assembly;
- providing electrical stimulation to the heart with the wired lead of the pulse generator;
- and
- synchronizing the electrical stimulation to the heart provided with the wireless electrode assembly to the electrical stimulation to the heart provided with the wired lead of the pulse generator.
