Abstract: Methods, compositions of matter, and devices for delivering a therapeutic composition to a heart of a subject using a biopolymer scaffold material are described. In some embodiments, the biopolymer scaffold material including the therapeutic composition may be attached to a first cardiac tissue of a subject. The therapeutic composition is delivered from the biopolymer scaffold material to the heart of the subject.

Abstract: A vascular connector includes a tubular sleeve graft having a first layer and a second layer and a cylindrical connector body positioned within the tubular sleeve graft between the first layer and the second layer. The cylindrical connector body is more rigid than the tubular sleeve graft and is configured to slide longitudinally within the tubular sleeve graft between the first layer and the second layer.

Abstract: Apparatus, systems, and methods are provided for monitoring AF episodes, delivering ATP pulses, and/or achieving electrical isolation of the left atrial appendage (LAA) of a patient's heart and/or preventing thrombus formation after electrical isolation. For example, devices are provided that may implanted from within the left atrium, e.g., to isolate the LAA, prevent thrombus formation within the LAA, facilitate endothelialization, and/or deliver pacing.

Abstract: Systems and methods are provided for optimizing hemodynamics within a patient's heart, e.g., to improve the patient's exercise capacity. In one embodiment, a system is configured to be implanted in a patient's body to monitor and/or treat the patient that includes at least one sensor configured to provide sensor data that corresponds to a blood pressure within or near the patient's heart; at least one adjustable component designed to cause blood to flow in a direction opposite to the normal direction (regurgitation) within the patient's heart; and a controller configured for adjusting the function of the at least one adjustable component based at least in part on sensor data from the at least one sensor.

Abstract: A system for detecting myocardial ischemia includes an implantable device having one or more leads connected thereto, at least one electrode on a lead of the device, and a microprocessor in the implantable device. The electrode is configured to stimulate the heart. The at least one sensor is configured to measure a characteristic of blood in a coronary vessel. The microprocessor is programmed to: run a stress test on the heart by stimulating the heart with the electrode; record data obtained from the at least one sensor during the stress test; and determine whether there is myocardial ischemia based upon the recorded data.
