Abstract:
Apparatus for providing a medical therapy at a treatment site inside a patient's body, comprising:(a) a medical device that administers the medical therapy when energized by an electrical current;(b) a polymer battery that is coupled to the medical device to supply the electrical current, the polymer battery having a polymer electrolyte that enables said polymer battery to be readily formed in at least one of three configurations, including:(i) a first configuration in which the polymer battery is elongate and integrally attached at one end to the medical device;(ii) a second configuration in which the polymer battery comprises one of a housing and a substrate for the medical device; and(iii) a third configuration in which the polymer battery and the medical device together comprise a capsule; and(c) an envelope for hermetically enclosing the polymer battery in the first configuration, and for hermetically enclosing both the polymer battery and the medical device in the second and third configurations, the envelope preventing fluids within the patient's body from contacting the polymer battery.
