Patent number: 8758365Abstract: A guiding accessory, for use in conjunction with a guidewire and a catheter of an implant system, facilitates passage of an elongate and flexible conductor of a relatively compact therapy delivery device to an implant site, for example, within the cardiac venous system, when a therapy generator of the device is held within a distal portion of the catheter, and the catheter, device and guiding accessory are advanced along the guidewire. The guiding accessory includes a helically extending wall that forms a lumen within which the device conductor and guidewire extend. After advancing the catheter, guiding accessory and device to the implant site, the helically extending wall is unwound from around the device conductor, for removal, preferably, by pulling proximally on a tension line, which is attached to a proximal end of the wall.Type: GrantFiled: August 3, 2011Date of Patent: June 24, 2014Assignee: Medtronic, Inc.Inventors: Matthew D. Bonner, Vladimir P. Nikolski

Publication number: 20140121720Abstract: A device includes a signal generator module, a processing module, and a housing. The signal generator module is configured to deliver pacing pulses to an atrium. The processing module is configured to detect a ventricular activation event and determine a length of an interval between the ventricular activation event and a previous atrial event that preceded the ventricular activation event. The processing module is further configured to schedule a time at which to deliver a pacing pulse to the atrium based on the length of the interval and control the signal generator module to deliver the pacing pulse at the scheduled time. The housing is configured for implantation within the atrium. The housing encloses the stimulation generator and the processing module.Type: ApplicationFiled: October 31, 2012Publication date: May 1, 2014Applicant: MEDTRONIC, INC.Inventors: Matthew D. Bonner, Saul E. Greenhut, Todd J. Sheldon, Wade M. Demmer

Patent number: 8623010Abstract: An instrument including an elongated shaft and a non-conductive handle is disclosed. The shaft defines a proximal section and a distal section. The distal section forms an electrically conductive tip. Further, the shaft is adapted to be transitionable from a straight state to a first bent state. The shaft is capable of independently maintaining the distinct shapes associated with the straight state and the first bent state. The handle is rigidly coupled to the proximal section of the shaft. The instrument is useful for epicardial pacing and/or mapping of the heart for temporary pacing on a beating heart, for optimizing the placement of ventricular leads for the treatment of patients with congestive heart failure and ventricular dysynchrony and/or for use in surgical ablation procedures.Type: GrantFiled: June 9, 2009Date of Patent: January 7, 2014Assignee: Medtronic, Inc.Inventors: Jon M.

Patent number: 8504156Abstract: A holding member for an implantable cardiac device facilitates tether attachment and removal, at time of implant, and snaring, or otherwise capturing, for subsequent explant. Preferably located in proximity to a proximal end wall of a shell of the device, the holding member includes a strut portion, being spaced proximally apart from the proximal end wall, a waist portion, defining a recess, and an engagement section, extending between the strut portion and the waist portion and overhanging the recess. The waist portion may either extend between the strut portion and the proximal end wall, or be formed in the shell, distal to the proximal end wall. Alternately, the holding member includes a loop element and an engagement element coupled thereto, between first and second segments thereof. The segments are initially formed to give the loop element an opening, and have a flexibility to be compressed together.Type: GrantFiled: August 26, 2011Date of Patent: August 6, 2013Assignee: Medtronic, Inc.Inventors: Matthew D.

Patent number: 7740623Abstract: The current invention discloses a method for treating infracted/ischemic injury to a myocardium by injecting a substance into the myocardium. The injected substance helps to prevent negative adaptive remodeling by providing mechanical reinforcement or mechanical reinforcement combined with biological therapy. A number of substances for injection are disclosed, including multi component substances such as platelet gel, and other substances. The substances disclosed may contain additives to augment/enhance the desired effects of the injection. The invention also discloses devices used to inject the substances.
