A means for treating breathing disorders by stimulating respiratory muscles or nerves to entrain respiratory systems while leaving respiratory drive intact. Embodiments of the invention employ frequency analysis to determine if appropriate stimulation energy is being applied.

Systems for treating disordered breathing by comparing stimulated and unstimulated breathing

Examples of the disclosure include a method to aid user monitoring of a disordered breathing treatment, comprising providing, by an application running on a user computing device, a patient-selection screen of a graphical user interface (GUI) on a display device of the user computing device; receiving, via an input field of the patient-selection screen, an input from the user indicative of a selected patient; communicating between the user computing device and a treatment system implanted in the selected patient, responsive to receipt of the input indicative of the selected patient, to transfer patient data from the treatment system to the user computing device; and providing, by the application, a diagnostic reporting and monitoring screen including one or more graphical illustrations indicative of sleep position data for the selected patient in combination with one or more graphical illustrations of other data for the selected patient on the GUI.

Respiratory rectification

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.

Antenna for an external power source for an implantable medical device, system and method

System for transcutaneous energy transfer to an implantable medical device adapted to be implanted under a cutaneous boundary having a housing having a first surface adapted to face the cutaneous boundary, the first surface of the housing of the implantable medical device having a first mating element, therapeutic componentry and a secondary coil operatively coupled to the therapeutic componentry. An external power source has housing having a first surface adapted to be placed closest to the cutaneous boundary, the first surface of the housing of the external power source having a second mating element and a primary coil capable of inductively energizing the secondary coil when externally placed in proximity of the secondary coil. The first mating element and the second mating element are configured to tactilely align the external power source with the implantable medical device.

Apparatus and method provide flexibility in generating a stimulation waveform to an electrode of an implantable medical device. The stimulation waveform comprises at least one stimulation pulse. The embodiment of the invention supports a generation of a stimulation pulse in which an amplitude and an electrical polarity of the stimulation pulse can be dynamically changed. The embodiment comprises a capacitor arrangement, a regulator and a switching array. The capacitor arrangement can be reconfigured with respect to an electrical reference through the switching array in order for the regulator to deliver the stimulation pulse to a pair of electrodes. In another embodiment, a plurality of stimulation waveforms are generated in which different stimulation waveforms are associated with different electrodes. With the embodiment, a plurality of regulators are connected and reconfigured to the capacitor arrangement in order that the different stimulation waveforms are generated by different regulators.

Voltage/current regulator improvements for an implantable medical device

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.

Independent therapy programs in an implantable medical device

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.

Programmable waveform pulses for an implantable medical device

A system and method for locating an implantable medical device. The system consists of a flat &ldquo;pancake&rdquo; antenna coil positioned concentric with the implantable medical device target, e.g. the drug reservoir septum. The system further features a three location antenna array which is separate from the implantable device and external to the patient. The antenna array features three or more separate antennas which are used to sense the energy emitted from the implanted antenna coil. The system further features a processor to process the energy ducted by the antenna array. The system senses the proximity to the implant coil and, thus, the implant device by determining when an equal amount of energy is present in each of the antennas of the antenna array and if each such ducted energy is greater than a predetermined minimum. When such a condition is met, the antenna array is aligned with the implant coil. Thus the needle port through the antenna array is lined up with the septum of the drug reservoir. Alternative embodiments are further disclosed in which the processor and antenna array are positioned within the implanted device while the coil is external to the patient.

System for locating implantable medical device

A testing method for use with a patient stimulation system includes providing a stimulation system including a patient control unit. The patient control unit initiates and terminates treatment periods. At least one period of stimulation to stimulate the patient is automatically provided upon initiating a treatment period. Another method includes a system test method for use with a therapy system. The method includes providing a therapy system having a plurality of components; the therapy system physiologically interacting with a patient. A diagnostic self test of a component of the therapy system is performed internally to the system to determine if the component is functioning properly at a time when the therapy system is not interacting physiologically with the patient. Apparatus for using such methods are also provided.

Diagnostic testing methods and apparatus for implantable therapy devices

An insensitive pellet ignitor utilizes a slapper type detonator to initiate an insensitive explosive material. The insensitive explosive material is retained in a high strength housing which confines and dissipates the explosion. The insensitive explosive material is retained in a collar placed in a chamber having an orifice leading to propellant. The orifice does not allow the shockwave from the insensitive explosive to prematurely expel the propellant so that the propellant is ignited from the hot gases and particles resulting from the explosion which are ported through the orifice to the propellant.
