Electrical stimulation device having multiple stimulation channels

摘要

An implantable electrical stimulation device configured to treat multiple pelvic conditions of a patient includes a pulse generator, memory, first and second electrode leads comprising one or more electrodes, a switch and a controller. The switch has a first state, in which the first electrode lead is electrically coupled to the pulse generator, and a second state, in which the second electrode lead is electrically coupled to the pulse generator. The controller includes at least one processor that is configured to execute at least one stimulation program stored in the memory. The controller is also configured to selectively set the switch in the first or second state. Electrical stimulation pulses generated by the pulse generator responsive to the execution of the stimulation program are delivered to the first or second electrode lead depending on the state of the switch.

1. Implantable electrical stimulation device comprising:
a pulse generator; memory containing a first stimulation program and a second stimulation program; first and second electrode leads each comprising one or more electrodes; a switch having a first state in which the first electrode lead is electrically coupled to the pulse generator, and a second state in which the second electrode lead is electrically coupled to the pulse generator; and a controller comprising at least one processor configured to execute the first and second stimulation programs stored in the memory, the controller configured to selectively set the switch in the first or second state; wherein:
electrical stimulation pulses generated by the pulse generator are delivered to the first electrode lead responsive to the execution of the first stimulation program by at least one processor when the switch is in the first state;electrical stimulation pulses generated by the pulse generator and delivered to the second electrode lead responsive to the execution of the second stimulation program by the at least one processor when the switch is in the second state;the stimulation pulses generated by the pulse generator in response to the execution of the first stimulation program are configured to treat a first pelvic condition; andthe stimulation pulses produced by the pulse generator in response to the execution of the second stimulation program are configured to treat a second pelvic condition that is different from the first pelvic condition.
