    摘要: A method for decreasing risk of ventricular tachycardia following myocardial infarction increases cell-to-cell coupling and/or excitability in the border zone of an infarcted region of myocardial tissue. Enhanced conduction to treat the border zone is carried out by genetically modifying myocytes in the border zone to form more gap junctions and/or sodium channels and/or calcium channels. Alternatively, enhanced conduction is carried out by incorporating cells into the border zone that form gap junctions with the myocytes and/or form sodium channels and/or form calcium channels.

    摘要: In general, the invention is directed to systems and techniques for assessing a risk of ventricular tachyarrhythmia in a patient by measuring one or more biochemical markers that reflect the health of a patient. Typically, the patient submits a sample, such as a blood sample, which is tested for one or more biomarkers. Based upon the results of the tests, the patient's risk of ventricular tachyarrhythmia may be assessed. When the patient is found to be at risk, the patient may receive an implantable medical device or drug therapy to address the risk.

    摘要: Disclosed are compositions, methods and systems for preventing or treating cardiac dysfunction, particularly cardiac pacing dysfunction by genetic modification of cells of targeted regions of the cardiac conduction system. In particular, a bio-pacemaker composition is delivered to cardiac cells to increase the intrinsic pacemaking rate of the cells, wherein the bio-pacemaker composition increases expression of a channel or subunit thereof that produces funny current and a T-type Ca2+ channel or subunit thereof, and expresses one or more molecules that suppresses the expression of the wild type potassium channel.

    摘要: A method for coating internal surfaces of a turbine engine component comprises flowing an aluminide containing gas into passages in the turbine engine component so as to coat the internal surfaces formed by the passages, allowing the aluminide containing gas to flow through the passages and out openings in external surfaces of the turbine engine component, and flowing a volume of a gas selected from the group consisting of argon, hydrogen, and mixtures thereof over the external surfaces to minimize any build-up of an aluminide coating on the external surfaces.

    摘要: A medical device identifies a hemodynamically unstable arrhythmia based upon optical hemodynamic sensor signals. The optical hemodynamic sensor includes a light source for transmitting light corresponding to first and second wavelengths through a blood perfused tissue of a patient and a light detector for generating optical signals corresponding to an intensity of the detected light at the first and second wavelengths. At a low motion period for the patient, optical signals are obtained from the optical hemodynamic sensor and are analyzed to determine a baseline motion level for the patient. Subsequent signals obtained from the optical hemodynamic sensor are compared to the baseline motion levels, with only those signals corresponding to periods where motion does not exceed the baseline level of motion being further analyzed to determine if they are consistent with a hemodynamically unstable arrhythmia.

    摘要: A cardiac pacemaker and method of its use. The pacemaker is provided with a pacing electrode array configured for location at a left anterior portion of a patient's thorax between the patients third and sixth ribs, outside the patient's thoracic cavity. The pacing electrode array includes multiple pacing electrodes and preferably includes one or more steering electrodes for configuring the electrical field produced by delivery of pacing pulses to avoid unwanted nerve and muscle stimulation while allowing cardiac stimulation. The electrode array may be located subcutaneously, submuscularly or on the patient's skin.

    摘要: SubQ ICDs are disclosed that are entirely implantable subcutaneously with minimal surgical intrusion into the body of the patient and provide distributed cardioversion-defibrillation sense and stimulation electrodes for delivery of cardioversion-defibrillation shock and pacing therapies across the heart when necessary. Configurations include one hermetically sealed housing with 1 or, optionally, 2 subcutaneous sensing and cardioversion-defibrillation therapy delivery leads or alternatively, 2 hermetically sealed housings interconnected by a power/signal cable. The housings are generally dynamically configurable to adjust to varying rib structure and associated articulation of the thoracic cavity and muscles. Further the housings may optionally be flexibly adjusted for ease of implant and patient comfort.

    摘要: An externally actuable, hermetically sealed switch is incorporated with an implantable medical device (IMD). A patient applies pressure against the tissue over the IMD and actuates the switch. The actuation of the switch causes the IMD to take predetermined actions, such as recording data, inhibiting therapy, initiating therapy, increasing therapy, requesting information, initiating a communications session, or performing a status check. Thus, the patient is able to interact with the IMD without requiring an external device such as a programmer, patient activator or magnet.
