Abstract: An implantable medical device (IMD) includes a drug reservoir located within a reservoir chamber of the IMD that includes a first side and a second side directly opposite the first side defining a reservoir volume there between. The IMD further includes and a volume sensor system including an ultrasound transmitter within the reservoir chamber and positioned to transmit an ultrasound signal toward the second side at an angle relative to the second side and a plurality of ultrasound sensors adjacent to at least one of the first side or second side of the drug reservoir with each sensor positioned to selectively receive the signal from the transmitter at different reservoir volume levels to indicate a current volume capacity of the drug reservoir.

Abstract: An implantable medical lead for sacral modulation therapy is disclosed. The implantable medical lead includes a lead body having a distal portion. An electrode is electrically coupled to the lead body and configured to generate a stimulation field or to sense electrical fields. A fixation mechanism is coupled to the distal portion. The fixation mechanism is configured to anchor the implantable medical lead against an interior wall of a blood vessel. The electrode can effect the stimulation field from within the vessel to stimulate a selected sacral nerve or sense electrical signals such as muscle or nerve responses. Guided implantation of the medical lead or other medical leads through the body to a nerve of interest for neurostimulation via remote sensor is also disclosed.

Abstract: Examples of implantable medical leads or implantable medical systems with implantable medical leads to be anchored to a sacrum are disclosed. The implantable medical leads include a lead body having a distal portion. A fixation mechanism is coupled to the distal portion. An electrode array is mechanically coupled to the fixation mechanism. In one example, the electrode array is directly coupled to the fixation mechanism. The electrode array is electrically coupled to the lead body and configured to generate a stimulation field. The fixation mechanism is configured to anchor the implantable medical lead to a sacrum and effect the stimulation field in a foramen of the sacrum.
