Abstract

An implantable pulse generator is provided that includes a power source, a wireless communication component configured to facilitate wireless communication with a non-implanted device and pulse-generating circuitry connected to the power source. The pulse-generating circuitry can be configured to identify, based on wireless communication with the non-implanted device, temporal and amplitude characteristics for electrical pulse stimuli and to trigger electrical output stimuli having the temporal and amplitude characteristics. The implantable pulse generation can further include one or more lead connections—each being shaped to engage a lead and electrically connected to the pulse-generating circuitry to enable the lead to deliver at least part of the electrical output stimuli triggered by the pulse-generating circuitry. The implantable pulse generator can further include one or more suture-engagement components, each including one or more holes each having a diameter that is at least 0.1 mm and less than 5 mm.

First claim
