Leads can be implanted to work in conjunction with a cardiac pacemaker or cardiac defibrillator. A lead for cardiac therapy may be inserted into an intercostal space associated with the cardiac notch of a patient. Devices for delivery may include, for example, a delivery system coupled with an electrical lead and having a handle, a component advancer and insertion tips. The handle is configured to be actuated by an operator and the component advancer is configured to advance an electrical lead into the patient. The insertion tips can be configured to close around the electrical lead within the component advancer, to push through biological tissue, and to open to enable the lead to advance into the patient. The electrical lead can also be maintained in a particular orientation during the advancement into the patient. ## Claims ### Claim 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. ### Claim 2 (depends on 1) The lead of claim 1, wherein at least one of the one or more electrodes protrudes from the distal portion of the lead. ### Claim 3 (depends on 1) The lead of claim 1, wherein at least one of the one or more electrodes includes scaffolding within the hollow area of the one or more electrodes. ### Claim 4 (depends on 1) The lead of claim 1, wherein at least one of the one or more electrodes comprises one or more channels on a surface of the electrode. ### Claim 5 (depends on 4) The lead of claim 4, the channels configured to increase a surface area of the one or more electrodes that may come into contact with biological tissue of a patient. ### Claim 6 (depends on 1) The lead of claim 1, wherein at least one of the one or more electrodes comprises two intersecting channels on a surface of the electrode. ### Claim 7 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; scaffolding comprising a plurality of conductive beams and/or members placed 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. ### Claim 8 (depends on 7) The lead of claim 7, wherein at least one of the one or more electrodes protrudes from the distal portion of the lead. ### Claim 9 (depends on 7) The lead of claim 7, wherein at least one of the one or more electrodes includes scaffolding within the hollow area of the one or more electrodes. ### Claim 10 (depends on 7) The lead of claim 7, wherein at least one of the one or more electrodes comprises one or more channels on a surface of the electrode. ### Claim 11 (depends on 10) The lead of claim 10, the channels configured to increase a surface area of the one or more electrodes that may come into contact with biological tissue of a patient. ### Claim 12 (depends on 7) The lead of claim 7, wherein at least one of the one or more electrodes comprises two intersecting channels on a surface of the electrode.
