摘要：
An implantable pulse generator (IPG) allowing for trial stimulation in a fully implanted solution is disclosed. At the time the leads are implanted, a micro IPG having lead connection block(s) is also implanted and connected to the leads. To keep the micro IPG suitably small, it preferably does not include a battery, and is instead powered continuously via magnetic induction using a magnetic field produced by an external charger, such as a charging patch. A coil in the micro IPG picks up and rectifies this magnetic field to provide power to stimulating electronics in the IPG. Because of its small size (e.g., ≤；10 cm3), implantation of the micro IPG can occur at the same time the leads are implanted in the patient without inconvenience. Should stimulation therapy with the micro IPG prove effective, a larger, permanent IPG can later be implanted and connected to the implanted leads.
