Patent number: 11154704Abstract: A system for drawing blood from a heart of a patient, includes a blood pump, an outflow cannula and a flexible cannula assembly. The cannula assembly further includes a flexible cannula body including a proximal end, a distal end, an inner wall defining a lumen, and an outer wall. A tip is coupled with the distal end of the cannula body, and an anchor is coupled to the tip. The anchor is configured to engage an internal structure of the heart and resists movement of the cannula assembly in at least one direction along the flexible cannula body. A ring member is configured to be coupled to the heart wall and is positioned at least partially around the outer wall of the cannula body proximally relative to the tip. The ring member is further configured to provide hemostasis between the heart wall and the cannula body.Type: GrantFiled: December 19, 2017Date of Patent: October 26, 2021Assignee: CircuLite, Inc.Inventors: Robert C. Farnan, Robert G. Hudgins, John Dockter

Publication number: 20080033235Abstract: 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: ApplicationFiled: January 30, 2007Publication date: February 7, 2008Applicant: Acorn Cardiovascular, Inc.Inventors: J. Shapland, Robert Walsh, John Dockter, John Vanden Hoek

Publication number: 20070219407Abstract: A method for applying a cardiac support device to a heart of a mammal includes surgically accessing a heart, providing a cardiac support device including a jacket, and positioning the jacket around at least a portion of the heart by applying a pulling force to the jacket. The step of positioning the jacket can include using a tool from a position superior to the heart to pull the jacket onto the heart. One device for placing a cardiac support jacket onto the heart includes first and second tubular walls. The second tubular wall is oriented within the first tubular wall and against an internal surface of the first tubular wall. The second tubular wall includes a plurality of grooves and has an open interior volume to hold the cardiac support jacket. Another device for placing a cardiac support jacket onto the heart includes a tubular wall having a plurality of lumens extending between opposite ends of the tubular wall.Type: ApplicationFiled: May 18, 2007Publication date: September 20, 2007Applicant: Acorn Cardiovascular, Inc.Inventors: John Vanden Hoek, Jody Rivers, John Dockter
