摘要:
System, method and antenna for an external power source for an implantable medical device having therapeutic componentry and a secondary coil operatively coupled to the therapeutic componentry. A housing has a first surface adapted to be placed closest to the secondary coil of the implantable medical device. A primary coil is operatively coupled to the external power and is capable of inductively energizing the secondary coil, the primary coil being wound forming generally concentric loops having an axis. The housing has a protrusion extending from the first surface.

摘要:
Apparatus and method provide flexibility in generating a stimulation waveform to an electrode of an Implantable Neuro Stimulator (INS). The stimulation waveform is synthesized for each rate period interval. Each rate period interval is partitioned into time intervals, during which stimulation pulses, recharging, and time duration delays may be induced. With the embodiment of the invention, a second stimulation pulse, having different electrical characteristics than a first stimulation pulse, may be generated during the rate period interval. An embodiment utilizes apparatus comprising a waveform controller and a waveform generator that are controlled by the waveform controller. The waveform controller uses waveform parameters to instruct the waveform generator to form stimulation pulses. Any of the components may be adjusted or deleted in the generation of the stimulation waveform. The embodiment enables any of the associated waveform parameters to be updated at the waveform controller in order to alter the stimulation waveform.

Apparatus and method for independently delivering a plurality of therapy programs in an implantable medical device. A therapy controller configures the device to generate independent pulse trains associated with a plurality of therapy programs and dynamically configures the electrodes to deliver the independent pulse trains to the patient. Once configured, the implantable medical device delivers the plurality of therapy programs to the patient wherein the therapy programs may overlap in time.

摘要:
The invention is a device and method for determining the current status and remaining life of a power source in an implantable neurological tissue stimulator. The invention contemplates a method, performed in a system without human intervention, that includes the steps of assessing the power source voltage of the power source in an IPG, determining, using the power source voltage, where in the power source life cycle the power source is, and taking action in response to the determination of where in the power source life cycle the power source is. The invention also includes a device that embodies the method described above. The device, which is partially resident in an IPG and partially resident in an external device such as a programmer measures the power source voltage in the IPG, using the power source voltage determines where in the power source life cycle the power source is and takes appropriate action in response to the determination of where in the power source life cycle the power source is. A processor, either on the IPG or in the programmer is the preferred structure for determining where in the power source life cycle the power source is and for directing the appropriate action in response to the determination of where in the power source life cycle the power source is.
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.

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.
