1. A minimally invasive implantable tibial nerve stimulation device having a reduced power requirement duty cycle, comprising:
a hermetically sealed enclosure configured to house a pulse generating circuit,
the hermetically sealed enclosure constructed of at least one of a biocompatible titanium or stainless steel and formed as an elongated tube having a circular cross-section with an overall length of less than about thirty millimeters to enable minimally invasive implantation of the hermetically sealed enclosure at an implant site within a body of a patient;
a lead tethered to one end of the hermetically sealed enclosure by way of an electrically insulated, sealed header,
the lead including two or more spaced apart electrodes in electrical communication with the pulse generating circuit carried near a distal end of the lead,
the lead configured to be positioned such that at least one of the two or more spaced apart electrodes is in proximity to a tibial nerve of a patient for the delivery of a neurostimulation therapy to the tibial nerve of the patient as a treatment for symptoms related to an overactive bladder;
an insulative outer coating at least partially surrounding the hermetically sealed housing configured to protect the enclosure and to reduce patient discomfort; and
one or more fixation elements to enable stable fixation of the tibial nerve stimulation device at the implant site; and
wherein the one or more fixation elements are arranged between the hermetically sealed housing and the two or more spaced apart electrodes.
