Publication number: 20150051670Abstract: Devices and methods compensate for perturbations in a stimulation signal caused by external conditions such as a magnetic field of an MRI machine so that stimulation therapy may continue in the presence of the external condition. Compensation for the perturbations during a stimulation pulse of a stimulation phase may be provided by using feedback within a stimulation current source. Perturbations during a recharge phase may be addressed by utilizing an active recharge at least when the external condition is present. Furthermore, compensation for perturbations during a recharge pulse of the active recharge phase may be provided by using feedback within a recharge current source. Passive recharge may be used instead of active recharge when the external condition is not present to preserve battery life of the stimulation device. The stimulation device may include a sensor to detect the external condition so that an appropriate mode of recharge may be chosen.Type: ApplicationFiled: August 15, 2013Publication date: February 19, 2015Applicant: Medtronic, Inc.Inventors: Robert Hocken, Heather Orser, Wesley Santa, Larry E.

Patent number: 8956352Abstract: Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function or of vascular structures that feed or perfuse the neural fibers.Type: GrantFiled: October 25, 2011Date of Patent: February 17, 2015Assignee: Medtronic Ardian Luxembourg S.a.r.l.Inventors: Kevin Mauch, Mario Alvarado, Robert Beetel, William Chang, Justin Goshgarian, Leonila Rivera, Sukyoung Shin, Michele Silver, Sina Som, Andrew Wu, Denise Zarins, Juanita Sanchez-Cole, Maria G.

Patent number: 8958870Abstract: A therapy program may be modified based on information indicative of a change in a therapy field, which may represent a region of a patient's tissue to which therapy is delivered. Upon receiving information indicative of a therapy field change, an algorithmic model of a present therapy field may be generated and compared to an algorithmic model of a baseline therapy field, which indicates a therapy field that provides efficacious therapy to the patient. If a characteristic of the present therapy field differs from the baseline therapy field model, the current therapy program may be modified. In another example, upon receiving information indicative of a therapy field change, the current therapy program may be modified, and an algorithmic model of a therapy field based on the modified therapy program may be compared to a baseline therapy field model to determine whether the modified therapy program is a suitable alternative.Type: GrantFiled: January 23, 2009Date of Patent: February 17, 2015Assignee: Medtronic, Inc.Inventors: Martin T.
