The present disclosure is directed to an implantable medical device including a housing having a generally planar portion, and a piezoelectric transducer disposed within the housing, wherein a receiving face of the piezoelectric transducer is arranged at an oblique angle with respect to a poling axis of the piezoelectric transducer, and an electrode to deliver a neurostimulation therapy. The implantable medical device is configured to receive energy signals from an external device and transduce the received energy signals into electrical power.

Acoustic power transfer for implantable medical device

A medical system for treating incontinence includes an implantable medical device (IMD) implantable proximate to a tibial nerve of a patient comprising therapy delivery circuitry configured to provide electrical stimulation therapy proximate the tibial nerve of the patient for treating incontinence, and processing circuitry configured to: during an implant period, determine a set of stimulation parameters to control the therapy delivery circuitry, during an induction period after the implant period, initiate electrical stimulation therapy according to the set of stimulation parameters, during a first maintenance period, determine an adjustment to the set of stimulation parameters as first maintenance period stimulation parameters to reduce the electrical stimulation therapy from the induction period, and during a second maintenance period, determine an adjustment to the set of stimulation parameters as second maintenance period stimulation parameters to reduce the electrical stimulation therapy from the first maintenance period.

Low healthcare provider interaction and outcome based programming

Aspects of the present disclosure are directed to an implantable medical device including a housing containing components therein configured for delivering neurostimulation therapy, and an anchoring feature included with the housing. The implantable medical device also includes a lead having an electrode. In one aspect, the implantable medical device may include a guidewire passageway configured to allow the lead of implantable medical device to be introduced over a guidewire.

Minimally invasive neurostimulation device

A leadless neurostimulation device having a header unit including at least one primary electrode having a contact surface that defines an external surface of the leadless neurostimulation device, a housing including a secondary electrode positioned on the same side of the leadless neurostimulation device as the at least one primary electrode, and a anchor device including at least one suture point for securing the leadless neurostimulation device to patient tissue or at least one protrusion nub configured to create mechanical resistance that impedes relative movement between wherein the leadless neurostimulation device and the patient tissue when implanted, where the at least one primary electrode and the secondary electrode are configured to transmit an electrical stimulation signal therebetween to provide electrical stimulation therapy to a target nerve of a patient.

Minimally invasive leadless neurostimulation device

The invention provides methods for treating a neurological disorder or deficit, such as tinnitus and phantom limb pain.

Multi-modal synchronization therapy

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.

Implantable medical device with drug reservoir volume sensor system

A system may receive first information relating to a patient captured during a baseline period that is prior to the patient receiving stimulation. The system may receive second information relating to the patient captured during an initial therapy assignment. The second information may include testing data generated by delivering stimulation during an implant procedure. The system may determine initial stimulation program settings based on the first information, the second information and population-informed information. The population-informed information may be related to other patients. The system may cause, during a training period, delivery of therapy based on the initial stimulation program settings.

Patient specific optimization algorithm

An implantable electrical stimulation device including an implant sized and configured to be implanted subcutaneously, the implant being configured to rectify a received pulse train of ultrasound into a single electrical pulse configured to stimulate a tibial nerve of a patient.

Implantable ultrasonic device

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.

Foramina-filling implantable medical lead

An example method includes receiving, by an implantable device and from an external device, an energy signal; transducing, by the implantable device, the energy signal into electrical power; outputting, by the implantable device and to the external device, a feedback signal that represents an absolute level of the electrical power transduced from the energy signal, wherein the feedback signal includes a first portion that represents a relative level of the electrical power transduced from the energy signal and a second portion that represents a reference voltage level; and delivering, by the implantable device, a level of electrical stimulation therapy proportional to the absolute level of the electrical power transduced from the energy signal.
