1. A method for treating a patient with neoplastic disease, comprising:
- providing at least one stimulator having at least two electrodes;
implanting the at least one stimulator in a neoplasm;
providing operating power to the at least one stimulator;
providing stimulation parameters to the at least one stimulator;
generating direct electric current in accordance with the stimulation parameters; and
delivering the current to neoplastic tissue near the at least one stimulator;
wherein the at least one stimulator has a size and shape suitable for placement entirely within the neoplasm.

Abstract
A small implantable stimulator(s) includes at least two electrodes for delivering electrical stimulation to surrounding tissue. The small stimulator provides means of stimulating a neoplasm with direct electrical current, such as relatively low-level direct current, without the need for external appliances during the stimulation session. The stimulator may be configured to be small enough to be implanted entirely within a neoplasm. Open- and closed-loop systems are disclosed.
