1. An implantable medical device, comprising:
a hermetically sealed housing 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 housing within a body of a patient;
a pulse generating circuit at least partially housed within the hermetically sealed housing;
an insulated lead tethered to one end of the hermetically sealed housing by way of an electrically insulated, sealed feedthrough, the insulated lead including:
two or more spaced apart electrodes in electrical communication with the pulse generating circuit, the two or more spaced apart electrodes carried near a distal end of the insulated lead and constructed of at least one of a conductive platinum or platinum iridium material,
the two or more spaced apart electrodes are configured to be positioned such that at least one electrode 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; and
a protective, resilient polymer enclosure at least partially surrounding the hermetically sealed housing; and
a fixation member arranged between the hermetically sealed housing and the two or more spaced apart electrodes, the fixation member configured to anchor the implantable medical device at an implant site.
