Hybrid stent

1. A method of delivering a stent, the stent having an expandable first segment having a first radial force RF 1 and a first diameter D 1 and an expandable second segment having a second radial force RF 2 and a second diameter D 2 , 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 RF 1 >RF 2 and D 1 =D 2 after expanding the expandable first stent segment and expanding the expandable second stent segment.

2. The method of claim 1 , wherein the expandable first stent segment in the first stent segment expanded state has a flexibility F 1 and the expandable second stent segment in the second stent segment expanded state has a flexibility F 2 , wherein F 1 <F 2 .

3. The method of claim 1 , wherein the expandable first stent segment after expanding has a flexibility F 1 and the expandable second stent segment after expanding has a flexibility F 2 , wherein F 1 <F 2 .

4. The method of claim 1 , wherein the expandable first stent segment and the expandable second stent segment have a common lumen.

5. The method of claim 1 , wherein the stent further comprises an expandable third stent segment having a third stent segment compressed state and a third stent segment expanded state, wherein the third stent segment is between the expandable first stent segment and the expandable second stent segment, the method further comprising placing and expanding the expandable third stent segment after placing and expanding the first expandable stent segment and before placing and expanding the second expandable stent segment, the third expandable stent segment having a radial force RF 3 in the third stent segment expanded state, wherein RF 1 >RF 3 >RF 2 .

6. The method of claim 1 , wherein the stent further comprises an expandable third stent segment having a third stent segment compressed state and a third stent segment expanded state, wherein the expandable third stent segment is between the expandable first stent segment and the expandable second stent segment and having a radial force that varies along length of the expandable third stent segment in the third stent segment expanded state.

7. The method of claim 6 , wherein the radial force of the expandable third stent segment in the third stent segment expanded state is greater at a region adjacent the expandable first stent segment in an expanded state than at a region adjacent the expandable second stent segment in an expanded state.

8. The method of claim 1 , wherein the expandable first stent segment comprises a flare at an end opposite the expandable second stent segment.

9. 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 RF 1 and a first diameter D 1 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 RF 2 and a second diameter D 2 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 RF 1 >RF 2 and D 1 =D 2 .

10. The method of claim 1 , wherein the expandable first stent segment in the first stent segment expanded state has a flexibility F 1 and the expandable second stent segment in the second stent segment expanded state has a flexibility F 2 , wherein F 1 <F 2 .

11. The method of claim 1 , wherein the expandable first stent segment and the expandable second stent segment have a common lumen.

12. The method of claim 1 , wherein the stent further comprises an expandable third stent segment having a third stent segment compressed state and a third stent segment expanded state, wherein the third stent segment is between the expandable first stent segment and the expandable second stent segment and having a radial force RF 3 in the third stent segment expanded state, wherein RF 1 >RF 3 >RF 2 .

13. The method of claim 1 , wherein the stent further comprises an expandable third stent segment having a third stent segment compressed state and a third stent segment expanded state, wherein the expandable third stent segment is between the expandable first stent segment and the expandable second stent segment and having a radial force that varies along length of the expandable third stent segment in the third stent segment expanded state.

14. The method of claim 13 , wherein the radial force of the expandable third stent segment in the third stent segment expanded state is greater at a region adjacent the expandable first stent segment in the first stent segment expanded state than at a region adjacent the expandable second stent segment in the second stent segment expanded state.

15. The method of claim 1 , wherein the expandable first stent segment comprises a flare at an end opposite the expandable second stent segment.
