Patent number: 11517433Abstract: A delivery device for a collapsible heart valve includes an operating handle and a catheter assembly. The operating handle includes a frame defining a movement space therein, a carriage assembly moveable in a longitudinal direction within the movement space, and a coupler having locked and unlocked conditions, the coupler being operatively connected to the carriage assembly for movement therewith. The catheter assembly includes a shaft around which a valve-receiving compartment is defined, the shaft being operatively connected to one of the frame or the carriage assembly, and a distal sheath operatively connected to the carriage assembly for movement therewith between a closed condition adapted to maintain the valve in the compartment and an open condition adapted to fully deploy the valve.Type: GrantFiled: December 20, 2019Date of Patent: December 6, 2022Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Bradley Charles Knippel, Huisun Wang, Ralph Joseph Thomas, Jacob John Daly

Publication number: 20220354644Abstract: A holder for a prosthetic heart valve includes a base having an annular portion defining an aperture, and a spool rotatably mated with the base. The spool has a platform and a head extending in a longitudinal direction from the platform. The holder further includes a button housing having an aperture sized and shaped to receive the head of the spool, and a button inserted in the button housing. The button housing is detachably coupled to the spool in an assembled condition. The button is movable relative to the button housing to move the button housing from a condition locked to the spool to a condition removable from the spool.Type: ApplicationFiled: April 19, 2022Publication date: November 10, 2022Applicant: St. Jude Medical, Cardiology Division, Inc.Inventors: Richard Kaleta, Bradley Charles Knippel, Ryan J.

Patent number: 10758351Abstract: A delivery device for a collapsible prosthetic heart valve includes an operating handle and a catheter assembly. The operating handle may include a housing defining a movement space therein, a carriage assembly moveable in a longitudinal direction within the movement space, a deployment actuator coupled to the housing and rotatable relative to the housing, and a coupling assembly rotationally fixed to the deployment actuator. The catheter assembly may include a first shaft around which a compartment is defined and a distal sheath operatively connected to the carriage assembly. Movement of the carriage assembly in the longitudinal direction in the movement space may move the distal sheath between the closed condition and the open condition. The coupling assembly may have an engaged position in which rotation of the deployment actuator moves the carriage assembly, and a disengaged position in which rotation of the deployment actuator does not move the carriage assembly.Type: GrantFiled: November 28, 2017Date of Patent: September 1, 2020Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Benjamin E. Morris, Eric E. Bielefeld, Gregory R. Furnish, Ralph Joseph Thomas, Khoi A. Le, Bradley Charles Knippel, Valerie J. Glazier
