Publication number: 20230355955Abstract: The embodiments relate to cardiac assist devices that comprise a jacket that wraps the exterior of the heart, where the jacket comprises a left chamber and a right chamber overlaying the left and right ventricles of the heart, respectively, where the chambers are expanded pneumatically to exert pressure on the heart and thereby mechanically assist its pumping. The timing of expansion of the left and right bladders is controlled by an electrical controller to match the desired or natural timing of contraction of the left and right ventricles, where both the left and right chambers may not expand simultaneously but are timed to optimize assistance of the heart. The embodiments provide jackets that apply pneumatic pressure to the right and left ventricles separately in timing to provide mechanical cardiac resynchronization therapy, as distinct from the conventional electrical stimulation cardiac resynchronization therapy.Type: ApplicationFiled: May 29, 2023Publication date: November 9, 2023Inventors: William J. Rissmann, Allan R. Robinson, Theodore J. Lillehei

Patent number: 9993653Abstract: In a subcutaneous implantable cardioverter/defibrillator, cardiac arrhythmias are detected to determine necessary therapeutic action. Cardiac signal information is sensed from far field electrodes implanted in a patient. The sensed cardiac signal information is then amplified and filtered. Parameters such as rate, QRS pulse width, cardiac QRS slew rate, amplitude and stability measures of these parameters from the filtered cardiac signal information are measured, processed and integrated to determine if the cardioverter/defibrillator needs to initiate therapeutic action.Type: GrantFiled: November 14, 2016Date of Patent: June 12, 2018Assignee: CAMERON HEALTH, INC.Inventors: Gust H. Bardy, William J. Rissmann, Alan H. Ostroff, Paul J. Erlinger, Venugopal Allavatam

Publication number: 20160338773Abstract: Method and systems for ablating nerves including measurement of physiological parameters and/or electrical conduction. The method may include ablating nerves within an artery of a patient such as the renal artery and may include advancing a catheter into the artery, measuring a physiological parameter, emitting an electrical pulse into a wall of the artery, measuring the physiological parameter during or after the step of emitting the electrical pulse, ablating the artery wall, then repeating the steps of measuring the physiological parameter, emitting an electrical pulse, and measuring the physiological parameter during or after the step of emitting the electrical pulse. The change in the physiological parameter caused by the electrical pulse before ablation may be compared to the change in the physiological parameter caused by the electrical pulse after ablation to determine the degree of nerve ablation achieved and whether or not to perform further ablation.Type: ApplicationFiled: August 3, 2016Publication date: November 24, 2016Inventors: Jin Shimada, Gregory G.

Publication number: 20160089531Abstract: In a method, an electrode lead is provided that includes a tubular lead body, an electrode supported by the lead body, a rotatable member, a deployable member and a deployment mechanism. The rotatable member is contained within a distal end of the tubular lead body. The deployable member is attached to the rotatable member and comprises a tissue anchor that includes mesh. Also in the method, the distal end of the tubular lead body is positioned proximate target tissue of a patient. The rotatable member is rotated relative to the tubular lead body. The deployable member is driven along the central axis, out the distal end of the tubular lead body, and into the target tissue using the deployment mechanism responsive to the rotation of the rotatable member. The deployment member does not rotate about the central axis with the rotation of the rotatable member.Type: ApplicationFiled: November 20, 2015Publication date: March 31, 2016Inventors: Matthew S.

Patent number: 8718760Abstract: A subcutaneous cardiac device includes two electrodes and a stimulator that generates a pulse to the electrodes. The electrodes are implanted between the skin and the rib cage of the patient and are adapted to generate an electric field corresponding to the pulse, the electric field having a substantially uniform voltage gradient as it passes through the heart. The shapes, sizes, positions and structures of the electrodes are selected to optimize the voltage gradient of the electric field, and to minimize the energy dissipated by the electric field outside the heart. More specifically, the electrodes have contact surfaces that contact the patient tissues, said contact surfaces having a total contact area of less than 100 cm2. In one embodiment, one or both electrodes are physically separated from the stimulator. In another embodiment, a unitary housing holds the both electrodes and the stimulator.Type: GrantFiled: May 6, 2013Date of Patent: May 6, 2014Assignee: Cameron Health Inc.Inventors: Gust H.
