Abstract
A connecting band for a highly flexible tissue-type heart valve having a stent with cusps and commissures that are permitted to move radially. The connecting band follows the cusps and commissures and extends outwardly. The valve is connected to the natural tissue along the undulating connecting band using conventional techniques, such as sutures. The connecting band may be a cloth-covered inner suture-permeable member and attaches to the underside of the valve at the cusps to provide support to the stent and to the outer side of the valve at the commissures. The connecting band includes commissure portions defining generally axial gaps that help permit flexing of the valve. The inner member may include one or more slits along the cusps to enhance flexibility. The inner member may further include a continuous outwardly projecting sewing ridge around its periphery which includes a series of ribs separated by grooves around the inflow edge of the cusps. The sewing ridge enables supra-annular implant of a valve constructed with the connecting band.
