Patent application numberDescriptionPublished
20080300585Method and device for performing cooling-or cryo-therapies for, e.g., angioplasty with reduced restenosis or pulmonary vein cell necrosis to inhibit atrial fibrillation - The present invention provides an enhanced method and device to inhibit or reduce the rate of restenosis following angioplasty or stent placement. The invention involves placing a balloon tipped catheter in the area treated or opened through balloon angioplasty immediately following angioplasty. The balloon, which can have a dual balloon structure, may be delivered through a guiding catheter and over a guidewire already in place from a balloon angioplasty. A fluid such as a perfluorocarbon may be flowed into the balloon to freeze the tissue adjacent the balloon, this cooling being associated with reduction of restenosis. The catheter may also be used to reduce atrial fibrillation by inserting and inflating the balloon such that an exterior surface of the balloon is in contact with at least a partial circumference of the portion of the pulmonary vein adjacent the left atrium.12-04-2008
20090259279SPLANCHNIC NERVE STIMULATION FOR TREATMENT OF OBESITY - A method for the treatment of obesity or other disorders by electrical activation or inhibition of the sympathetic nervous system is disclosed. This activation or inhibition can be accomplished by stimulating the greater splanchnic nerve or other portion of the sympathetic nervous system using an electrode. This nerve activation can result in reduced food intake and increased energy expenditure.10-15-2009
20090306736ACCELEROMETER-BASED MONITORING OF THE FREQUENCY DYNAMICS OF THE ISOVOLUMIC CONTRACTION PHASE AND PATHOLOGIC CARDIAC VIBRATIONS - Methods and systems are disclosed that characterize cardiac function using an acceleration sensor to acquire and analyze the frequency dynamics associated with the isovolumic contraction phase (“ICP”). This information can be used to characterize heart function; optimize therapy for cardiomyopathy, including CRT therapy (including pacing intervals and required pharmacologic therapy); and to optimize CCM therapy. In addition, this information can be used to identify target pacing regions for CRT lead placement. Further, analyzing the frequency dynamics can be used to characterize pathologic heart vibrational motion, such as mitral regurgitation and the third or fourth heart sound, and the response of this motion to therapy for cardiomyopathy.12-10-2009
20100049063DEVICES AND METHODS FOR ACCELEROMETER-BASED CHARACTERIZATION OF CARDIAC FUNCTION AND IDENTIFICATION OF LV TARGET PACING ZONES - Systems according to the invention employ an acceleration sensor to characterize displacement and vibrational LV motion, and uses this motion data to characterize the different phases of the LV cycle for analyzing LV function. Systems may identify a target pacing region or regions in the LV or RV using the acceleration sensor by localizing regions of late onset of motion relative to the QRS, or isovolumic contraction, or mitral valve closure, or by pacing of target regions and measuring LV function in response to pacing. Systems further provide an implantable or non-implantable acceleration sensor device for measuring LV motion and characterizing LV function. An implantable myocardial acceleration sensing system (“IAD”) includes at least one acceleration sensor, a data acquisition and processing device, and an electromagnetic, e.g., RF, communication device. The IAD may be integrated into the pacing lead of a CRT device and can operate independently of the CRT IPG.02-25-2010
20100106207DYNAMIC NERVE STIMULATION IN COMBINATION WITH OTHER EATING DISORDER TREATMENT MODALITIES - A method for treatment of obesity or other disorders by electrical activation or inhibition of nerves is disclosed. This activation or inhibition can be accomplished by stimulating a nerve using an electrode. The method further comprises performing a surgical procedure and/or administering a weight loss drug.04-29-2010
20100145408Splanchnic Nerve Stimulation For Treatment of Obesity - A method for the treatment of obesity or other disorders by electrical activation or inhibition of the sympathetic nervous system is disclosed. This activation or inhibition can be accomplished by stimulating the greater splanchnic nerve or other portion of the sympathetic nervous system using an electrode. This nerve activation can result in reduced food intake and increased energy expenditure.06-10-2010
20100234907Splanchnic Nerve Stimulation for Treatment of Obesity - A method for the treatment of obesity or other disorders by electrical activation or inhibition of the sympathetic nervous system is disclosed. This activation or inhibition can be accomplished by stimulating the greater splanchnic nerve or other portion of the sympathetic nervous system using an electrode. This nerve activation can result in reduced food intake and increased energy expenditure.09-16-2010
20100249889Neural Stimulation For Treatment of Metabolic Syndrome and Type 2 Diabetes - Systems and methods are described for treating metabolic syndrome and/or Type 2 diabetes, and/or one or more of their attendant conditions, by neural stimulation. In one embodiment, an implantable pulse generator is electrically coupled to a peripheral nerve, such as the splanchnic nerve. Neural stimulation configured to either block transmission or stimulate transmission of the peripheral nerve may be used to treat metabolic syndrome and Type 2 diabetes.09-30-2010
