Claim:
1. A wireless pacing electrode delivery system, comprising: a guide sheath including a distal end and a lumen extending to the distal end; and an intravascularly-deliverable medical device positionable within the lumen of the guide sheath; a fixation device attached to and extending away from the medical device, wherein the fixation device is configured to engage heart wall tissue, the fixation device configured to be advanced distal of the distal end of the guide sheath to engage the heart wall tissue; wherein the fixation device includes four tines attached to and extending distally from a ring, the four tines having a non-deployed configuration and a deployed configuration, wherein in the non-deployed configuration the four tines point distally toward the heart wall tissue to pierce into the heart wall tissue without penetrating entirely through the heart wall, and wherein the four tines are biased to curl outwardly to the deployed configuration when unconstrained to engage the heart wall tissue.
