Abstract
A stent system is provided that includes a first radially-expandable stent, which includes mechanical structural elements arranged so as to form a first tubular structure having a lumen; and a second radially-expandable stent, which includes mechanical structural elements, which are arranged so as to form a second tubular structure, and which are shaped so as to provide tissue-engaging structures that protrude radially outward from the second tubular structure. The second stent is shaped so as to be concentrically disposed within the lumen of the first stent such that the tissue-engaging structures extend between the mechanical structural elements of the first stent in order to engage and be anchored to tissue of a blood vessel, thereby facilitating anchoring of the first stent in the blood vessel. A tissue anchor is coupled to the first stent by a flexible band. Other embodiments are also described.
