Abstract
A percutaneous electrical therapy system with electrode angle of entry control. In one embodiment, the system includes a control unit; an electrode assembly adapted to deliver electrical therapy to a patient, the electrode assembly including an electrode electrically connectable to the control unit, the electrode having a sharp point at a distal end adapted to be inserted into a patient's tissue; and an electrode depth control assembly adapted to control insertion of the electrode's point to a predetermined depth into the patient's tissue. The electrode depth control assembly can have a limit stop limiting length of travel of the electrode's point. The system can also include the percutaneous electrode and depth control assembly described above apart from the control unit. In another embodiment, a method of performing percutaneous electrical therapy includes providing an electrode assembly comprising an electrode, the electrode having a sharp point at a distal end; using an electrode depth control assembly to insert the sharp point of the electrode a predetermined depth into a patient's tissue; and applying an electrical signal to the electrode from a control unit.
