Patent ID: 8771340

Claim:
A medical product for the securement of one or more valve prostheses within the vasculature of a patient, comprising: a percutaneous device having an expandable portion configured to expand within the vasculature of a patient; at least one vascular valve prosthesis positioned over the expandable portion, the at least one valve prosthesis including at least a first flexible leaflet having a bottom edge region for securement against a wall of a vessel of the vasculature in a first curved path extending partially circumferentially around and longitudinally along the wall of the vessel to form a curved bottom edge of a deployed leaflet configuration within the vessel; a first band of bolster material layered on and in contact with the bottom edge region of the first flexible leaflet between the bottom edge region of the first flexible leaflet and the expandable portion; the first band of bolster material having first and second ends and a first edge extending therebetween along a curvilinear path when the expandable portion is expanded within the vasculature of a patient so as to track the curved bottom edge of the deployed leaflet; and a first plurality of fasteners having a head portion and a body portion, wherein the fasteners are positioned such that the head portion contacts the expandable portion between the first band of bolster material and the expandable portion and wherein the fasteners are configured to extend through both the first band of bolster material and the first flexible leaflet to secure the first band of bolster material and the bottom edge region of the first flexible leaflet to the wall of the vessel in the first curved path extending partially circumferentially around and longitudinally along the wall of the vessel to form the curved bottom edge of the deployed leaflet configuration when the expandable portion is expanded within the vasculature of a patient; wherein at least two of the fasteners are connected; and wherein the at least two connected fasteners and band of bolster material together comprise a tack strip.
