Abstract
Abstract A heart valve prosthesis has a frame that includes at least one outwardly extending annular flange adjacent to a suturing ring and a band comprising an inwardly extending annular flange that is capable of engagement with the annular flange of the frame. A tortuous path is formed between the annular flange of the frame and the annular flange of the band that can engage and restrain a suture placed between them. One or more split portions or tab portions on the band are adapted to lock the band in engagement with the flange of the frame. Such a device can be used to more easily replace a heart valve by advancing a sutures through a suturing ring on the valve and the valvular rim such that they are brought outward of the flange extending from the frame and then advancing the band over the valve and over the sutures at a proximal, outflow end of the valve until the band engages the flange and captures the sutures between the band and the flange.
