Abstract
A compressible and expandable stent assembly for implantation in a body lumen such as a mitral valve, the stent assembly including at least one stent barrel that is shaped and sized so that it allows for normal operation of adjacent heart structures. One or more stent barrels can be included in the stent assembly, where one or more of the stent barrels can include a cylinder with tapered edge.

16. A compressible and expandable stent assembly for implantation in a body lumen, the stent assembly comprising:
-
a first stent comprising a first length that extends along a first longitudinal axis and a tubular structure that is compressible and expandable in a radial direction; a second stent comprising a second length that extends along a second longitudinal axis that is less than the first length and a tubular structure that is compressible and expandable in a radial direction, wherein the first longitudinal axis is generally parallel to the second longitudinal axis, wherein the second stent is coupled adjacent to and extends from the first stent along a tangential line that extends in a generally parallel direction to the first and second longitudinal axes and in a generally perpendicular direction to the radial expansion direction of the first and second stents; a first prosthetic valve disposed within the first stent; and a second prosthetic valve disposed within the second stent. - View Dependent Claims (17, 22, 23, 24, 25)

18. A method of positioning a stent assembly into the mitral valve area of a patient, the method comprising the steps of:
-
providing a stent assembly comprising a first stent having an outer peripheral surface and a first length, and a second stent having an outer peripheral surface that is adjacent to and extending from the outer peripheral surface of the first stent, wherein the second stent has a second length that is greater than the first length; and positioning the stent assembly in the mitral valve area so that the first stent is adjacent to an anerolateral portion of the mitral valve and the second stent is adjacent to a posteromedial portion of the mitral valve; wherein the length of the first stent minimizes interference with the functioning of an adjacent aortic valve and provides enough contact area to impede dislodging of the stent assembly.

19. A delivery system for delivering a stent to a body lumen and expanding the stent, the delivery system comprising:
-
a first axis; a second axis perpendicular to the first axis; an expandable central balloon comprising first and second opposite sides and centered on the intersection of the first and second axes; a first expandable side balloon positioned adjacent to the first side of the central balloon and centered on the first axis; and a second expandable side balloon positioned adjacent to the second side of the central balloon and centered on the first axis; wherein a first width of the device measured along the first axis is greater than a second width of the device measured along the second axis. - View Dependent Claims (20, 21)
