STENTS FOR PROSTHETIC HEART VALVES

摘要

A stented valve including a stent structure (10) including a generally tubular body portion having a first end, a second end, an interior area, a longitudinal axis, and a plurality of vertical wires (12) extending generally parallel to the longitudinal axis around a periphery of the body portion, wherein the plurality of vertical wires includes multiple commissure wires (16) and at least one structural wire positioned between adjacent commissure wires, and a plurality of V-shaped wire structures (18,20,22) having a first end, a second end, and a peak between the first and second ends, wherein a first end of each V-shaped structure extends from a first vertical wire and a second end of each V-shaped structure extends from a second vertical wire that is adjacent to the first vertical wire, wherein each V-shaped structure is oriented so that its peak is facing in the same direction relative to the first and second ends of the body portion, and a valve structure including a plurality of leaflets attached to the stent structure within the tubular body portion.
