Abstract:
A gene regulatory system controls biomarker, gene therapy or endogenous gene expression by emitting one or more forms of energy that regulate gene expression. The system may include a sensor to sense a signal indicative of a need for therapy. The regulation of gene expression is controlled based on the sensed signal and/or a user command. In one embodiment, the system delivers one or more electrical therapies in conjunction with controlling gene therapy or endogenous gene expression.
Abstract:
Embodiments of the invention are related to systems and methods for setting parameters of implantable medical devices, amongst other things. In an embodiment, the invention includes a method for programming an implantable medical device including sensing concentrations of a predictive marker such as ET-1 in a patient, selecting programming parameter values based on the sensed concentrations of the predictive marker, and implementing the selected programming parameter values. In an embodiment the invention includes a method for detecting arrhythmia in a patient including sensing concentrations of the predictive marker in a patient, selecting a level of stringency to be used in an arrhythmia detection module based on the sensed concentrations of the predictive marker, sensing electrical signals in the patient, and evaluating the sensed electrical signals for indicia of an arrhythmia using the arrhythmia detection module. Other embodiments are also included herein.
Abstract:
An apparatus comprises an implantable sensor and a detection circuit. The implantable sensor provides a physiologic sensor signal and is to be positioned at a lymph node of a subject. The detection circuit detects a change in a physiologic parameter of the lymph node that exceeds a threshold change, and deems that the change in the physiologic parameter indicates a change in inflammation of an organ associated with the lymph node.
Abstract:
A system delivers multiple enhanced therapies to limit myocardial damage post-revascularization. The system includes a catheter that incorporates features for delivering cardiac protection pacing therapy (CPPT) and intermittent ischemia therapy. In one embodiment, a method for delivering cardiac protection therapies to a heart is provided. One or more catheters are provided having a balloon, at least one pacing electrode and at least one hemodynamic sensor. Cardiac protection pacing therapy (CPPT) and intermittent ischemia therapy are concurrently delivered using the one or more catheters. The pacing and ischemia are adapted to protect the heart from ischemic and reperfusion injuries. The delivery of the CPPT and the intermittent ischemia are controlled using a closed-loop system monitoring a signal sensed by the at least one hemodynamic sensor.
