A leadless biostimulator including an electrical feedthrough assembly (100) mounted on a housing (110) is described. An electronics compartment (202) of the housing (102) can contain an electronics assembly (202), and the electrical feedthrough assembly (100) can include an electrode body (302, 700, 800,1302, 1402, 1502, 1602, 1802) including an electrode wall (502, 1310, 1410, 1510, 1610, 1810) extending distally from an electrode base (504, 1312, 1412, 1512, 1612, 1812) around an electrode cavity (506, 1314, 1414, 1514, 1614, 1814), an electrode tip (304, 1304, 1404, 1504, 1604, 1704, 1804) mounted on a distal end of the electrode body (302, 700, 800, 1302, 1402, 1502, 1602, 1802), a filler (416, 1316, 1416, 1516, 1616, 1816) including a therapeutic agent in the electrode cavity (506,1314,1414,1514,1614,1814) between the electrode base (504,1312,1412, 1512, 1612, 1812) and the electrode tip (304, 1304, 1404, 1504, 1604, 1704, 1804), and one or more holes (418, 1002) in at least one of the electrode body (302) or the electrode tip (304, 1304, 1404, 1504, 1604, 1704, 1804). The one or more holes (418, 1002) are configured to deliver the therapeutic agent to the target tissue when the therapeutic agent elutes from the filler (416, 1316, 1416, 1516, 1616, 1816) and passes through the one or more holes (418, 1002).
