Abstract
A stent includes a high radial force segment and a highly flexible segment, where the diameters of the high radial force segment and the highly flexible segment are substantially the same. The stent may further be placed with an additional stent segment, where the additional stent segment has a radial force similar to the radial force of the highly flexible force segment.
Claims15
A method of delivering a stent, the stent having an expandable first segment having a first radial force RF1 and a first diameter D1 and an expandable second segment having a second radial force RF2 and a second diameter D2, the method comprising:
- crimping a stent onto a catheter including radially compressing and lengthening a plurality of rings connected by flexible connectors;
- placing the expandable first stent segment at a target location and expanding the expandable first stent segment and subsequently placing the expandable second stent segment and expanding the expandable second stent segment;
- wherein RF1>RF2 and D1=D2 after expanding the expandable first stent segment and expanding the expandable second stent segment.
A method of delivering a stent, the stent having an expandable first segment comprising a plurality of first interconnected struts allowing the expandable first stent segment to have a first stent segment compressed state and a first stent segment expanded state the expandable first segment having a first radial force RF1 and a first diameter D1 in the first stent segment expanded state and an expandable second segment comprising a plurality of second interconnected struts allowing the expandable second stent segment to have a second stent segment compressed state and a second stent segment expanded state, the expandable second stent segment having a second radial force RF2 and a second diameter D2 in the second stent segment expanded state, the method comprising:
- crimping a stent onto a catheter including radially compressing and lengthening a plurality of rings connected by flexible connectors;
- placing the expandable first stent segment at a target location and expanding the expandable first stent segment and subsequently placing the expandable second stent segment and expanding the second segment
- wherein RF1>RF2 and D1=D2.
