Polymer battery for internal light device

Apparatus for providing a light therapy at a treatment site inside a patient's body, comprising:

• (a) a light source adapted for use inside a patient's body, the light source producing light to administer the light therapy when energized by an electrical current;
• and
• (b) a polymer battery adapted for use inside a patient's body having an elongate cable-like configuration with opposite ends, one end being connected to the light source to provide the electrical current for energizing the light source to administer the light therapy, and the other end being adapted to couple to a source of an electrical current for charging the polymer battery.

Apparatus for delivering a medical treatment to a patient, comprising:

• (a) a medical device that is adapted to deliver the medical treatment to the patient;
• and
• (b) a housing for the medical device, said housing being disposed around at least a portion of the medical device, said housing comprising a polymer battery that includes a polymer electrolyte and a plurality of electrodes that are electrically connected to the medical device, said polymer battery supplying an electrical current to energize the medical device.

Apparatus for delivering an electrical current to energize a medical device used by an ambulatory patient, comprising:

• (a) a housing, said housing being formed of a polymer battery that includes an outer electrode, an inner electrode, and a polymer electrolyte disposed between the outer electrode and the inner electrode, said outer electrode defining a substantial portion of a shape of the housing;
• and
• (b) a lead having a connection with the polymer battery, said lead conveying electrical current supplied thereby to the medical device.
