1. A wireless electrode delivery system, comprising:
a delivery catheter having a proximal end, a distal end and a lumen extending therein along a longitudinal axis; and
a wireless electrode assembly disposed within the lumen of the delivery catheter, the wireless electrode assembly including:
a body having a proximal end region, a distal end region, and a longitudinal axis;
an electrode positioned at the distal end region of the body; and
a plurality of tines arranged radially around the electrode, wherein each of the plurality of tines is configured be in a delivery configuration when the wireless electrode assembly is disposed within the lumen of the delivery catheter and configured to assume a deployed configuration when the wireless electrode assembly is deployed from the lumen of the delivery catheter, and wherein in the delivery configuration each of the plurality of tines is disposed in a straightened longitudinal orientation and includes a distal tip positioned at a distalmost extent of the plurality of tines, and wherein each of the plurality of tines is biased to curl away from the longitudinal axis in the deployed configuration such that a curved portion of each tine is located distal of the distal tip;
wherein the plurality of tines are configured to anchor the wireless electrode assembly into a target tissue site of a heart wall with the electrode in contact with the heart wall when shifting from the delivery configuration to the deployed configuration.
