Abstract

Wireguides and methods of making wireguides for delivery systems are provided. A wireguide for a delivery system according to the invention facilitates placement of an intraluminal medical device at a desired point of treatment. The wireguides include a plurality of indicia, each of which has a configuration that differs from that of at least one other indicium of the plurality of indicia.

Claims

1. A wireguide, comprising:

an elongate member having a proximal end and a distal end; and

a plurality of indicia disposed on the distal end of the elongate member, each indicium of the plurality of indicia formed of a radiopaque material and having a configuration that is different than a configuration of at least one other indicium of the plurality of indicia.

2. The wireguide according to claim 1, wherein the configuration of each indicium of the plurality of indica is a geometric shape.

3. The wireguide according to claim 2, wherein the configuration of each indicium of the plurality of indicia is a unique geometric shape.

4. The wireguide according to claim 1, wherein the configuration of each indicium of the plurality of indicia comprises an arrangement of dots.

5. The wireguide according to claim 4, wherein the configuration of each indicium of the plurality of indicia is a unique arrangement of dots.

6. The wireguide according to claim 5, wherein the plurality of indicia are axially positioned on the elongate member in an order based on the number of dots present in each indicium.

7. The wireguide according to claim 6, wherein the indicium comprising either the least or most dots is positioned distal to all other indicia in the plurality of indicia.

8. The wireguide according to claim 6, wherein the indicia are positioned on the elongate member in an order according to the number of dots in a configuration beginning at the distal end and moving towards the proximal end of the elongate member.

9. The wireguide according to claim 8, wherein the order comprises a sequence in which the number of dots in a particular configuration increases as the indicia move progressively farther from the distal and of the elongate member.

10. The wireguide according to claim 1, wherein the configuration of each indicium of said plurality of indicia comprises a numeral.

11. The wireguide according to claim 10, wherein the indicia are axially positioned on the elongate member in an order according to the numerals represented by the configurations of the indicia.

12. The wireguide according to claim 11, wherein the order comprises a sequence in which the numerals increase as the indicia move progressively farther from the distal end of the elongate member.

13. The wireguide according to claim 1, wherein the configuration of each indicium of said plurality of indicia comprises a set of spaced apart annular rings.

14. The wireguide according to claim 13, wherein the indicia are axially positioned on the elongate member to represent numerical positions increasing sequentially beginning at the distal end and moving toward the proximal end of the elongate member.

15. A wireguide comprising:

an elongate member having a proximal end and a distal end; and

a plurality of radiopaque indicia formed on the distal end of the elongate member, each indicium of the plurality of indicia having a unique configuration among all other indicia of the plurality of indicia.

16. The wireguide according to claim 15, wherein the configuration of each indicium of the plurality of indica is a geometric shape.

17. The wireguide according to claim 15, wherein the configuration of each indicium of the plurality of indicia comprises an arrangement of dots.

18. The wireguide according to claim 15, wherein the configuration of each indicium of said plurality of indicia comprises a numeral.

19. The wireguide according to claim 15, wherein the configuration of each indicium of said plurality of indicia comprises a set of spaced apart annular rings.

20. A wireguide comprising:

an elongate member having a proximal end and a distal end and a plurality of indica formed on the distal end;

wherein each indicium of the plurality of indicia has a unique configuration that comprises a geometric shape.
