Biostimulator having laterally extending pacing electrode

A biostimulator system, comprising:

• a biostimulator transport system;
• and
• a biostimulator mounted on the biostimulator transport system, wherein the biostimulator includes a body having a longitudinal axis and an electronics compartment containing pacing circuitry, and a header assembly mounted on the body along the longitudinal axis, wherein the header assembly includes a header housing having a lateral surface facing laterally outward from the longitudinal axis, and an electrode channel in the lateral surface, and wherein the header assembly includes a pacing electrode extending through the electrode channel along an electrode axis substantially orthogonal to the longitudinal axis.

A method, comprising:

• delivering a biostimulator to a target tissue, wherein the biostimulator includes a body having a longitudinal axis and an electronics compartment containing pacing circuitry, and a header assembly mounted on the body along the longitudinal axis, wherein the header assembly includes a header housing having a lateral surface facing laterally outward from the longitudinal axis, and an electrode channel in the lateral surface, and wherein the header assembly includes a pacing electrode extending through the electrode channel along an electrode axis substantially orthogonal to the longitudinal axis;
• and
• advancing the pacing electrode through the electrode channel into the target tissue.
