摘要:
A method of modifying cardiac tissue behavior, comprising applying a therapeutically effective electric field having an effect of modifying protein activation levels of at least one protein, and repeatedly applying the field at time intervals timed to increase the activation levels of the at least one protein beyond an activation level achieved by natural and/or paced excitation of the muscle without the application, to an extent about at least as high as a decay of the activation between applications of the field.
摘要:
A method of treating a cardiac arrhythmia, comprising: determining a desired arrhythmia control; selecting an electric field having an expected effect of modifying protein activity of at least one protein as a response of a cardiac tissue to the field, said expected effect correlated with said desired arrhythmia control; and applying said field to said cardiac tissue.
摘要:
A method of modifying tissue behavior, comprising: determining a desired modification of tissue behavior for at least one of treatment of a disease, short or long term modification of tissue behavior, assessing tissue state and assessing tissue response to stimulation; selecting an electric field having an expected effect of modifying protein activity of at least one protein as an immediate response of a tissue to the field, said expected effect correlated with said desired modification; and applying said field to said tissue.

A method of modifying tissue behavior, including cardiac tissue, comprising: determining a desired modification of tissue behavior for at least one of treatment of a disease, short or long term modification of tissue behavior, assessing tissue state and assessing tissue response to stimulation; selecting an electric field having a known effect of modifying protein activation levels of at least one protein as an immediate response of a tissue to the field, said known effect correlated with said desired modification; and applying said field to said tissue.
摘要:
Cardiomyopathy may be treated by distributing a space-occupying diastole-assist agent within the myocardium or within the cardiac venous system in a pattern about one or more chambers of the heart, such that the space-modifying agent integrates into and thickens at least part of the cardiac wall about the chamber so as globally to reduce wall stress, stabilize or even reduce chamber size, and/or improve diastolic function. Some patterns also cause a beneficial global reshaping of the chamber. These changes occur quickly and are sustainable, and have a rapid and sustainable therapeutic effect on cardiac function. Patterns of distribution of space-occupying agent within the myocardium for global resizing may also be used or augmented to treat localized conditions such as myocardial infarctions, overt aneurysm of the ventricular wall as typically forms in response to large transmural myocardial infarctions, and mitral regurgitation due to a noncompliant mitral valve. These techniques may also be used to treat localized conditions that may not yet have progressed to cardiomyopathy.
摘要:
Structurally supportive material is implanted or injected into cardiac veins as discrete masses at various sites in the cardiac venous system to reinforce the myocardium for the purpose of preventing, moderating, stopping or reversing negative cardiac remodeling due to various adverse cardiac conditions, both acute and chronic, or for the purpose of treating localize anomalies of the heart, or for both purposes. The sites may be arranged in a pattern about one or more chambers of the heart such that the masses cooperatively reduce stress in the chamber wall and reduce chamber size. Some patterns also cause a beneficial global reshaping of the chamber. These changes occur quickly and are sustainable, and have a rapid and sustainable therapeutic effect on cardiac function.
