Claim 14:
15. A method, comprising:
advancing a distal region of a catheter into a chamber of a heart, wherein the distal region has an inner lumen containing a biostimulator, wherein the biostimulator includes a housing having a longitudinal axis and an electronics compartment containing a processor configured to stimulate a target tissue, wherein the biostimulator includes a helical fixation element coupled to the housing and having a piercing tip, wherein the biostimulator includes an elongated member extending distally from the housing to a tissue contact region, wherein the biostimulator includes an electrode mounted on the elongated member at the tissue contact region, and wherein, when the biostimulator is in an undeployed state with the helical fixation element unattached to the target tissue, the electrode is longitudinally distal to the piercing tip; and
deploying the biostimulator from the distal region, wherein when the biostimulator is deployed the biostimulator is in a deployed state such that the helical fixation element is attached to the target tissue and the electrode is in contact with the target tissue of the chamber of the heart longitudinally proximal to the piercing tip.
