  • Patent number: 8032229
    Abstract: Systems and methods for adjusting a therapy delivered to a patient include detecting a value of at least one sensed patient parameter and adjusting a therapy parameter value to accommodate different patient parameter values. A data structure including a plurality of patient parameter values and associated therapy parameter values may be stored within a medical device or a programming device. Upon detecting a patient parameter value, an associated therapy parameter value from the data structure may be selected. If no therapy parameter value is associated with the detected patient parameter value, an intermediate therapy parameter value may be generated by interpolating between the most recently implemented therapy parameter value and a stored therapy parameter value. In some embodiments, the rate of shifting between parameters of two stored or interpolated therapy parameter values may be based on the rate of change of the patient parameter value over time.

  • Patent number: 8019416
    Abstract: An implantable pacing device for delivering ventricular pacing may be configured to intermittently reduce the AVD interval for beneficial effect in patients with compromised ventricular function (e.g., HF patients and post-MI patients). The AVD interval may be reduced in an AVD reduction mode, by shortening the AVD in an atrial triggered ventricular pacing mode or by switching to a non-atrial triggered ventricular pacing mode (e.g., VVI) and delivering paces at a rate above the intrinsic rate. The physiological effects of AVD reduction may be either positive or negative on cardiac output, depending upon the individual patient.

  • Patent number: 8010202
    Abstract: A critical element of a retinal prosthesis is the stimulating electrode array, which is placed in close proximity to the retina. It is via this interface that a retinal prosthesis electrically stimulates nerve cells to produce the perception of light. The impedance load seen by the current driver consists of the tissue resistance and the complex electrode impedance. The results show that the tissue resistance of the retina is significantly greater than that of the vitreous humor in the eye. Circuit models of the electrode-retina interface are used to parameterize the different contributors to the overall impedance.

  • Patent number: 7962215
    Abstract: Systems and methods are provided to improve respiratory function. Systems include an external electrical stimulator coupled to electrodes that stimulates diaphragm contraction and may optionally include a positive pressure mechanical ventilator. The system further includes an electrode suitable for temporary implantation. Electrical stimulation is provided to specific portions of the diaphragm, such as one hemidiaphragm preferentially over another. By preferentially contracting one hemidiaphragm, a specific portion of a lung may be expanded, such as a posterior portion. By the provision of the negative intrathoracic pressure from diaphragm contraction, greater expansion of specific portion of lung is achieved in relationship to air pressure within the lung, thereby improving compliance. Supplementation of stimulated diaphragm contraction with positive pressure driven air flow from a PPMV directs the air flow to specific portions of the lung.

  • Patent number: 7957802
    Abstract: Optimizing cardiac preload based on measured pulmonary artery pressure involves varying, for each repetition of an acute burst protocol, a parameter of pacing applied to a patient's heart during the acute burst protocol. Pulmonary artery pressure is measured during the repetitions of the acute burst protocol. The length of the repetitions is chosen so that the patient's baroreflex system does not adjust to the varied parameter of pacing during the repetitions of the acute burst protocol. An optimum ventricular preload is determined based on the measured pulmonary artery pressure. Pacing therapy is provided using a value of the parameter that is selected based on the determination of optimum ventricular preload.

  • Patent number: 7930022
    Abstract: An implantable medical device detects a tachyarrhythmia of a heart. During the detected tachyarrhythmia, the device determines a local myocardial impedance. Using the local myocardial impedance, the device determines whether there is sufficient perfusion to the heart. The device can then either deliver a less aggressive device therapy in response to the detected tachyarrhythmia when there is sufficient perfusion to the heart, or deliver a more aggressive device therapy in response to the detected tachyarrhythmia when there is insufficient perfusion to the heart. The perfusion information can also be used to alter tachyarrhythmia detection or classification.
