Patent number: 8623080Abstract: A method of using a prosthetic heart valve assembly can include implanting a first prosthesis directly into a native annulus. The first prosthesis can have a central longitudinal axis and a first engagement element. The method can also include engaging the first engagement element of the first prosthesis with a second engagement element of a second prosthesis to securely couple the second prosthesis to the first prosthesis. The second prosthesis can have a prosthetic valve. The first engagement element engages the second engagement element by moving the second prosthesis towards the first prosthesis in a direction generally parallel to the central longitudinal axis until the first engagement element engages the second engagement element.Type: GrantFiled: September 22, 2011Date of Patent: January 7, 2014Assignee: Medtronic, Inc.Inventors: Thomas J.

Patent number: 8460373Abstract: A method for implanting a heart valve assembly includes a first annular prosthesis for implantation within a tissue annulus, a second valve prosthesis, and a multi-lobed connection adapter to secure the second prosthesis to the first prosthesis. In one embodiment, the adapter is arranged to allow the second prosthesis to be secured to the first prosthesis in a predetermined angular orientation. During use, the first annular prosthesis is implanted into the annulus, and the second valve prosthesis is inserted into the annulus. The adapter secures the second prosthesis relative to the first prosthesis to align the second prosthesis with the first prosthesis in a predetermined angular orientation; and secure the second prosthesis to the first prosthesis in the predetermined angular orientation.Type: GrantFiled: July 1, 2011Date of Patent: June 11, 2013Assignee: Medtronic, Inc.Inventors: Thomas J.
