1. A compressible and expandable stent assembly for implantation in a body lumen, the stent assembly comprising:
a first stent barrel including:
a first tubular structure that is compressible and expandable in a radial direction,a first lumen extending through the first tubular structure extending from a first open end of the tubular structure to a second open end of the tubular structure, wherein a first central longitudinal axis is defined by the first lumen,a first inner luminal surface, anda first outer surface having a first peripherywherein the second open end of the first stent barrel is tapered; a second stent barrel including:
a second tubular structure that is compressible and expandable in a radial direction,a second lumen extending through the second tubular structure extending from a first open end of the second tubular structure to a second open end of the second tubular structure, wherein a second central longitudinal axis is defined by the second lumen,a second inner luminal surface, anda second outer surface having a second periphery,wherein the second open end of the second stent barrel is tapered; a first prosthetic valve disposed within the first lumen of the first stent barrel; and a second prosthetic valve disposed within the second lumen of the second stent barrel, wherein the first longitudinal axis is generally parallel to the second longitudinal axis, wherein the first stent barrel is fixed to the second stent barrel along a common area of the first outer surface and the second outer surface defining a first tangential line parallel to the first and second longitudinal axes along each of the first and second stent barrels such that first stent barrel has a fixed position relative to the second stent barrel that is maintained in both a delivery configuration and a deployed configuration. |
