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: 8838238Abstract: A method and apparatus are disclosed for treating a condition of a patient's heart includes placing a first electrode and/or a second electrode in a right ventricle of the heart. In one example, a reference electrode is placed within the patient and internal or external to the heart. A pacing signal is generated including a first signal component, a second signal component and a reference component with the first and second signal components having opposite polarity and with both of the first and second components having a potential relative to the reference component. The pacing signal and the placement of the electrodes are selected to alter a contraction of a left ventricle of the heart.Type: GrantFiled: October 4, 2012Date of Patent: September 16, 2014Assignee: Cardiac Pacemakers, Inc.Inventors: Daniel Felipe Ortega, Alberto German Giniger, Qingsheng Zhu, J.

Publication number: 20100317918Abstract: A method and device are disclosed for treating congestive heart disease. The material of the device is secured to the heart proximate the septal wall. The material covering the ventricles may or may not have the same tension and or compliance. The device can be constructed as a unitary “jacket” that is slipped over the apex of the heart. Alternately, the device implanted as one, two or more separate components. In one embodiment, the material covers both the left and right ventricles. In another embodiment, the material covers only one ventricle. The device may include at least one adjustment mechanism configured to adjust the tension of the material.Type: ApplicationFiled: August 18, 2010Publication date: December 16, 2010Applicant: Acorn Cardiovascular, Inc.Inventors: J.

Publication number: 20100185050Abstract: A jacket of biological compatible material has an internal volume dimensioned for an apex of the heart to be inserted into the volume and for the jacket to be slipped over the heart. The jacket has a longitudinal dimension between upper and lower ends sufficient for the jacket to surround a lower portion of the heart with the jacket surrounding a valvular annulus of the heart and further surrounding the lower portion to cover at least the ventricular lower extremities of the heart. The jacket is adapted to be secured to the heart with the jacket surrounding at least the valvular annulus and the ventricular lower extremities. The jacket is adjustable on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain circumferential expansion of the heart beyond the maximum adjusted volume during diastole and to permit unimpeded contraction of the heart during systole.Type: ApplicationFiled: April 1, 2010Publication date: July 22, 2010Applicant: ACORN CARDIOVASCULAR, INC.Inventors: Clifton A. ALFERNESS, Donald G. ROHRBAUGH, J. Edward SHAPLAND, Michael J. GIRARD, Donald F. PALME, II, James E. COX

Patent number: 7326174Abstract: A device for treating cardiac disease of a heart having an upper portion and a lower portion divided by an A-V groove, the device including a jacket adapted to be secured to the heart, and a non-adherent material in association with the jacket. The jacket is fabricated from a flexible material defining a volume between an upper and a lower end, the jacket being adapted to be adjusted on the heart to snugly conform to an external geometry of the heart and assume a maximum adjusted volume for the jacket to constrain expansion of the heart beyond the maximum adjusted volume during diastole and permit substantially unimpeded contraction of the heart during systole. As a result of the flexible material, the jacket allows unimpeded diastolic filling of the heart.Type: GrantFiled: May 4, 2004Date of Patent: February 5, 2008Assignee: Acorn Cardiovascular, Inc.Inventors: James Cox, Michael J. Girard, Donald F. Palme, II, Donald G. Rohrbaugh, Hani N. Sabbah, J. Edward Shapland, II, Robert G. Walsh
