Abstract:
1. A method for delivering a prosthesis to a body lumen, the method comprising: introducing into the body lumen one or more self-expanding tubular prostheses carried at axially spaced apart locations along an elongate flexible member, the self-expanding tubular prostheses being axially separated and unlocked within a sheath and constrained in a contracted configuration within the sheath, the body lumen having a lesion with a lesion length; selecting a first group of the self-expanding tubular prostheses for delivery by proximally retracting a pusher member disposed proximal of the first group of prostheses, the first group of prostheses having a combined length that substantially traverses the lesion length; distally advancing the pusher member to axially translate the selected first group of prostheses within the sheath to bring the first group of prostheses into locking engagement with each other within the sheath; and uncovering the first group of prostheses from the sheath so that they are unconstrained from expansion, wherein the first group expands at the first treatment site.
