A medical device comprising:
a catherer and a stent mounted on the catherer, the stent comprising
a first radial ring and a second radial ring, the first and second radial rings each comprising a series of alternating peaks and valleys and capable of expansion from a constricted diameter to an expanded diameter; and
a plurality of interconnecting links extending between said first radial ring and said second radial ring, at least one of said plurality of interconnecting links having an initially curved configuration which straightens as said first and second radial rings are expanded from said constricted diameter to said expanded diameter and being connected at its first end to an intermediate point on said first radial ring between a peak and an adjacent valley and on its second end to an intermediate point on said second radial ring between a peak and an adjacent valley. |
