Abstract:
A percutaneous electrical therapy system comprising:a housing having an aperture; an electrode movably coupled to the housing and movable relative to the housing between a stowed position and a deployed position, the electrode being electrically connectable to a control unit to deliver electrical therapy to a patient, the electrode comprising a sharp point at a distal end configured to be inserted through the aperture into a patient's tissue; an electrode insertion axial supporter configured to provide axial support to the electrode during insertion of the electrode into the patient's tissue; and an electrode insertion pain reducer configured to reduce pain experienced by the patient during insertion of the sharp point of the electrode into the patient's tissue, the electrode insertion pain reducer including an annular protrusion extending axially outwardly at least partially around and proximate to the aperture to receive the electrode and stretch the patient's skin when the housing is placed against the skin.
