1. An electrical lead for implantation in a patient, the lead comprising:
a distal portion including one or more electrodes coupled to the distal portion, the one or more electrodes configured to generate therapeutic energy for biological tissue of the patient, the one or more electrodes including a hole configured to allow an ingress of fluid and one or both of corners and edges configured to enhance a current density in the one or more electrodes;
a conductive mesh comprising conductive wiring or a porous sheet of conductive material within a hollow area of the one or more electrodes; and
a proximal portion coupled to the distal portion, the proximal portion configured to engage a controller when the lead is implanted in the patient, the controller configured to cause the one or more electrodes to generate the therapeutic energy.
