Patent number: 9855049Abstract: Some embodiments of a system or method for treating heart tissue can include a control system and catheter device operated in a manner to intermittently occlude a heart vessel for controlled periods of time that provide redistribution of blood flow. In particular embodiments, the system can be configured to provide an estimation of the cumulative effects of the treatment. For example, some embodiments of the system or method can treat myocardium that is at risk of infarction by intermittently altering blood flow in a venous system to induce microcirculation within the myocardium, and can output a cumulative dosage value indicative of a measurement of progress of reducing an infarct size.Type: GrantFiled: December 11, 2013Date of Patent: January 2, 2018Assignee: Miracor Medical Systems GmbHInventors: Lars Roman Schiemanck, Martin Haidacher

Patent number: 9724102Abstract: In a method for intermittently occluding the coronary sinus, in which the coronary sinus is occluded using an occlusion device, the fluid pressure in the occluded coronary sinus is continuously measured and stored, the fluid pressure curve is determined as a function of time, and the occlusion of the coronary sinus is triggered and/or released as a function of at least one characteristic value derived from the measured pressure values. The pressure increase and/or pressure decrease per time unit each occurring at a heart beat are used as characteristic values.Type: GrantFiled: July 28, 2014Date of Patent: August 8, 2017Assignee: Miracor Medical Systems GmbHInventors: Werner Mohl, Loay Alzubaidi

Patent number: 9439600Abstract: Some embodiments of a system or method for treating heart tissue can include a catheter device that provides a user with the ability to perform a number of heart treatment tasks (before, during, and after a cardiac surgery or a percutaneous coronary intervention). In particular embodiments, the catheter device can be used to (i) precondition heart muscle tissue before the heart is isolated from the circulatory system, (ii) deliver cardioplegia into the coronary sinus during the cardiac surgery when the heart is isolated from the circulatory system, and (iii) control the blood flow through the heart after the heart is reconnected with the circulatory system. In some embodiments, the catheter device can perform some or all of: (i) intermittently occluding the coronary sinus, (ii) delivering a treatment fluid into the coronary sinus, and (iii) monitoring a flow rate of blood passing from the coronary sinus to the right atrium.Type: GrantFiled: August 5, 2013Date of Patent: September 13, 2016Assignee: Miracor Medical Systems GmbHInventor: Werner Mohl

Patent number: 9433381Abstract: Some embodiments of a system or method for treating heart tissue can include a control system and catheter device operated in a manner to intermittently occlude a heart vessel for controlled periods of time that provide redistribution of blood flow. In particular embodiments, the system and methods may be configured to monitor at least one input signal detected at a coronary sinus and thereby execute a process for determining a satisfactory time period for the occlusion of the coronary sinus. In further embodiments, after the occlusion of the coronary sinus is released, the control system can be configured to select the duration of the release phase before the starting the next occlusion cycle.Type: GrantFiled: December 23, 2011Date of Patent: September 6, 2016Assignee: Miracor Medical Systems GmbHInventors: Werner Mohl, Gregor Neumayr, Alem Jusic

Patent number: 8996106Abstract: In a method for the intermittent occlusion of a vein draining the organ system, in which the vein is occluded by an occlusion device, the fluid pressure in the occluded vein is continuously measured and stored, the behavior of the fluid pressure is determined as a function of time, and the occlusion of the vein is triggered and/or released as a function of at least one characteristic value derived from the pressure measurements, pressure is applied during the occlusion in a pulsating manner. The device for the intermittent occlusion of a vein, including an occlusion device, a pressure measuring device for continuously measuring the fluid pressure in the occluded vein, and a memory for storing the fluid pressure behavior as a function of time, means are provided for applying a pulsating pressure in the occluded vein.Type: GrantFiled: August 5, 2013Date of Patent: March 31, 2015Assignee: Miracor Medical Systems GmbHInventor: Werner Mohl
