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.

Patent number: 9289298Abstract: The present disclosure is directed to an external cardiac basal annuloplasty system (ECBAS or BACE-System: basal annuloplasty of the cardia externally) and methods for treatment of regurgitation of mitral and tricuspid valves. The BACE-System provides the ability to correct leakage of regurgitation of the valves with or without the use of cardiopulmonary bypass, particularly when the condition is related to dilation of the base of the heart. This ECBAS invention can be applied to the base of the heart epicardially, either to prevent further dilation or to actively reduce the size of the base of the heart.Type: GrantFiled: March 17, 2014Date of Patent: March 22, 2016Assignee: Mardil, Inc.Inventors: JaiShankar Raman, P.

Patent number: 9005109Abstract: A cardiac constraint device comprising a jacket of biological compatible material and an adjustment member. The jacket is adapted to be secured to the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole. The adjustment mechanism is configured to alter the internal volume defined by the jacket after the jacket is secured to the heart. The invention also provides a method for treating cardiac disease.Type: GrantFiled: April 15, 2011Date of Patent: April 14, 2015Assignee: Mardil, Inc.Inventors: J. Edward Shapland, Robert G. Walsh, John David Dockter, John C. Vanden Hoek

Patent number: RE46927Abstract: The present invention relates to an external heart device, having a layered band dimensioned to be received around a patient's heart, which also includes at least one fillable chamber between the layers in the band that functions to apply localized pressure to the outside of the heart when filled. More particularly, the fillable chambers are positioned such that they exert an inward radial force on a heart valve. Areas between the fillable chambers may also be sized and positioned to form a bridge of little to no pressure over the vascular structures of the heart.Type: GrantFiled: January 10, 2014Date of Patent: July 3, 2018Assignee: Mardil, Inc.Inventors: Karl R. Leinsing, Jaishankar Raman
