Techniques and systems for monitoring cardiac arrhythmias and delivering electrical stimulation therapy using a subcutaneous device (e.g. subcutaneous implantable (SD)) and a leadless pacing device (LPD) are described. In one or more embodiments, a computer-implemented method includes sensing a first electrical signal from a heart of a patient through a SD. The first signal is stored into memory and serves as a baseline rhythm for a patient. Subsequently, a second signal is sensed from the heart through the SD. A cardiac condition can be detected within the sensed second electrical signal through the SD. A determination is made as to whether cardiac resynchronization therapy (CRT) is appropriate to treat the detected cardiac condition. A determination can then be made as to the timing of pacing pulse delivery to cardiac tissue through a leadless pacing device (LPD). The LPD receives communication from the SD requesting the LPD to deliver CRT to the heart. The SD senses and extracts data from a third electrical signal from the heart of the patient to determine whether the pacing by LPD provided efficacious resynchronization or whether the delivery and timing of the LPD pulse should be modified.

Targeted ablation of parathyroidal tissue is provided through hyperthermia adjuvant therapy. An in situ localization of parathyroidal tissue is obtained. A temperature-sensitive adjuvant is instilled into the parathyroidal tissue. Hyperthermia is therapeutically induced within the parathyroidal tissue. Heat-inducing energy is targeted into the parathyroidal tissue, which selectively includes the temperature-sensitive adjuvant. Application of the heat-inducing energy to the parathyroidal tissue is continued over a therapeutic range. In a further embodiment, the targeted ablation of the parathyroidal tissue is provided through hypothermia adjuvant therapy with the targeted use of cold-inducing energy.

Systems and methods are provided for delivering neurostimulation therapies to patients for treating chronic heart failure. A neural fulcrum zone is identified and ongoing neurostimulation therapy is delivered within the neural fulcrum zone. The implanted stimulation device includes a physiological sensor for recording the patient's response to the neurostimulation therapy on an ambulatory basis over extended periods of time.

In a method and apparatus for supplying wireless energy to a medical device (100) implanted in a patient, wireless energy is transmitted from an external energy source (104) located outside a patient and is received by an internal energy receiver (102) located inside the patient, for directly or indirectly supplying received energy to the medical device. An energy balance is determined between the energy received by the internal energy receiver and the energy used for the medical device, and the transmission of wireless energy is then controlled based on the determined energy balance. The energy balance thus provides an accurate indication of the correct amount of energy needed, which is sufficient to operate the medical device properly, but without causing undue temperature rise.

A bilateral hearing implant surgical template arrangement is described. An adjustable headpiece with left and right sides fits over the head of a surgical patient. There are left and right implant stimulator templates, each configured to conform against an underlying side of the patient's head and each connected to a corresponding left and right side of the adjustable headpiece by an adjustable connection. Each adjustable connection is configured to allow adjustment of the position of the implant stimulator template with respect to the adjustable headpiece so as to define stimulator implantation sites at symmetric locations on each side of the patient's head.

Techniques facilitating locating an implantable medical device (IMD) within a body of a patient are provided. An estimate of the location is determined based on strength information representative of strengths of communicative couplings between a communications head device and the IMD at various positions of the communications head device. The strength information can be updated periodically or based on specific events, such as changes to the body and/or an amount of time elapsed since strength information was previously obtained. Media representative of the estimate of the location and an image of the body can be output and can facilitate a patient or caregiver locating the IMD. In some embodiments, the media and image output can guide future placement of the communications head device on the patient to efficiently establish communication. Further, in some embodiments, numerous IMDs implanted within a single body can be identified and communication can commence.

A system for providing non-invasive neuromodulation to a patient includes a mouthpiece and a controller. The mouthpiece includes an elongated housing, a printed circuit board, control circuitry mounted within the elongated housing, and a cable for connecting to a controller. The controller includes an elongated u-shaped element, an electronic receptacle, and a microcontroller. A method for providing non-invasive neurorehabilitation of a patient including connecting a mouthpiece to a controller, transmitting a numeric sequence to the mouthpiece, generating a first hash code, transmitting the first hash code to the controller, generating a second hash code, comparing the second hash code with the first hash code, enabling electrical communication between the mouthpiece and the controller only if the first hash code matches the second hash code, contacting the mouthpiece with the patient's intraoral cavity, and delivering neurostimulation to the patient's intraoral cavity.

Couplings for implanted leads and external stimulators, and associated systems and methods are disclosed. A connector in accordance with a particular embodiment includes a first housing portion and a second housing portion pivotably connected to each other. The first housing portion has an elongated fixed stop opening. The second housing portion has a stop element and a plurality of connector contacts positioned to electrically contact a plurality of connection contacts of a spinal cord stimulation lead. The first and second housing portions are pivotably connected to each other to move between a partially-opened position in which the stop element is in a first location in the elongated fixed stop opening, and a closed position in which the stop element has a second location in the elongated fixed stop opening.

A bionic cochlea includes a fluid filled vessel having a window disposed in one of its walls and a flexible fluid filled tube in fluid communication at one end with the vessel through the window. The other end of the tube has a diaphragm in communication with the ossicles of a mammalian ear. The diaphragm flexes when exposed to an acoustic pulse to produce an acoustic pressure pulse in the fluid inside the tube and vessel. A plurality of piezoelectric nanowires is disposed within the fluid filled vessel. The nanowires vibrate in response to at least one predetermined wavelength in the acoustic pressure pulse transmitting through the fluid and produce electrical signals. Electrical wires in communication with the nanowires receive the electrical signals and pass these signals to the mammalian auditory nerve.
