摘要:
A system, method and implantable medical for concurrently providing a therapeutic output to a patient while communicating transcutaneously with an external device. The therapeutic output is provided to the patient with an implantable medical device wherein an electromagnetic signal is associated with at least one of recharging of a rechargeable power source and providing the therapeutic output. Bi-directional transcutaneous communication is conducted via via telemetry between the implantable medical device and an external device using a telemetry signal while the telemetry signal and the electromagnetic signal occur simultaneously.

Storable implantable medical device assembly and container for an implantable device having a charging sub-assembly. The implantable medical device has therapeutic componentry and a rechargeable power source operatively coupled to the therapeutic componentry. The charging sub-assembly having an electro-chemical power source, such as a battery, and a charging circuit operatively coupled to the electro-chemical power source. The implantable medical device and the charging sub-assembly are co-located within the container. The charging circuit of the charging sub-assembly is operatively coupled to the chargeable power source within the container to charge the rechargeable power source while the implantable medical device remains in the container. The charging sub-assembly may use inductive coupling to charge the implantable device mimicking implantable device charging following implantation.
摘要:
In one aspect, a programmer for an implantable medical device comprises a user interface that receives user input corresponding to one or more selected stimulation therapy parameters for delivering stimulation therapy to a patient with the implantable medical device and presents an energy consumption estimate of a power source based on the selected stimulation therapy parameters; and a processor that determines one or more programming options that, if selected, would alter the selected stimulation therapy parameters and reduce the energy consumption estimate. The user interface presents at least one of the programming options to reduce the energy consumption estimate to the user with an indication that user selection of one or more of the presented programming options would alter the selected stimulation therapy parameters to reduce energy consumption of the implantable medical device.

摘要:
Techniques are described for generating electrical stimulation current pulses for delivery of electrical stimulation therapy via a current-controlled system that emulates voltage pulses generated via a voltage-controlled system. In one example, a method includes receiving user input specifying a voltage level of electrical stimulation to be delivered by one or more of a plurality of electrodes implanted within the patient, selectively coupling the one or more electrodes to respective regulated current paths to deliver the electrical stimulation to the patient, selectively coupling at least another of the plurality of electrodes implanted within the patient to an unregulated current path to deliver the electrical stimulation to the patient, determining a regulated current for each respective regulated current path in order to produce the specified voltage level at the one or more electrodes selectively coupled to the respective regulated current paths, and delivering the determined regulated currents via the respective regulated current paths.
摘要:
Various programming techniques are described for medical devices that deliver electrical stimulation therapy that may include mapping between discrete electrical stimulation parameters and a graphical view of the electrical stimulation representing a stimulation zone generated by the parameters. In one example, a method includes receiving, via a programmer for an electrical stimulator, user input that graphically manipulates at least one of size and a shape of a graphical representation of at least one electrical stimulation zone displayed on the programmer, and defining a program to control delivery of electrical stimulation therapy based on the user input.
摘要:
Medical device recharging systems include a controller and a separate recharge device that communicate wirelessly together to provide recharging to an implantable medical device. Either the controller or the recharge device may also communicate wirelessly with the implantable medical device to obtain recharge status and other information. There may be multiple recharge devices present within communication range of the controller, and the controller may determine which recharge device to activate depending upon proximity of each recharge device to the implantable medical device. The controller may allow the recharge device that is active at any given time to change so that the patient having the implantable medical device can move about in the area where the recharge devices are located while recharging continues.
摘要:
This disclosure describes techniques for a method of charging a battery. In an example, the method includes charging the battery during a first charging session until a first charging termination parameter value is reached. The method also includes determining, for a second charging session, a second charging termination parameter value based on a duration of the first charging session, wherein the second charging termination parameter value is different than the first charging termination parameter value. The method also includes charging the battery during the second charging session until the second charging termination parameter value is reached.
