Abstract
A hybrid stent () includes at least one resilient ring () comprising a superelastic wire () formed in a sinusoidal pattern of alternating crests () and troughs () about a circumference of the ring (). A plurality of malleable cannula segments () overlie the superelastic wire at the crests and troughs. Each of the cannula segments () includes a bend () and has an inner diameter sized to allow relative motion between the wire () and the cannula segment (). The hybrid stent () may also include a plurality of gaps (), where each gap () is defined by a spacing between opposing cannula segments (). Deformation of the malleable cannula segments () dominates a response of the stent to substantially uniform radial forces, and deformation of the resilient ring () dominates a response of the stent to radially nonuniform crushing forces.
