Publication number: 20210401579Abstract: Devices and methods for providing localized pressure to a region of a patient's heart to improve heart functioning. The devices include a cardiac jacket made of a flexible biocompatible material and at least one inflatable bladder disposed on an interior surface of the jacket. Inflation of the bladder causes the bladder to expand to exert localized pressure against a region of the heart. In some cases, a phase-change material is filled into the bladder as a liquid and the material solidifies at body temperature. In some cases, a positioning tool is used prior to the implantation of the jacket in order to determine effective positions for the inflatable bladder(s) to be located on the heart to improve heart functioning.Type: ApplicationFiled: April 25, 2019Publication date: December 30, 2021Inventors: Eugene Andrew Grossi, William E. Cohn, George Gellert, Aaron J. Hjelle

Publication number: 20190217005Abstract: A method for implanting a cardiac support device (CSD) on a patient's heart. An amount of contrast agent sufficient to cause structures on the heart to be visible upon fluoroscopic or other imaging is introduced into the pericardial space surrounding the heart. The heart and contrast agent are imaged to provide a visual indication of the location of the structures of the heart. The CSD is placed on the heart using the visual indications provided by the imaging.Type: ApplicationFiled: December 21, 2018Publication date: July 18, 2019Applicant: Mardil, Inc.Inventors: William E.
