Publication number: 20110166413Abstract: 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: March 16, 2011Publication date: July 7, 2011Applicant: Mardil, Inc.Inventors: Clifton A. ALFERNESS, Donald G. ROHRBAUGH, James 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

Patent number: 6902522Abstract: 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 delivery source for the delivery of one or more therapeutic agents to the surface of the heart. 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: June 12, 2000Date of Patent: June 7, 2005Assignee: Acorn Cardiovascular, Inc.Inventors: Robert G.
