Abstract

An intravascular device having an elongate shaft and a proximal hub assembly. The proximal hub assembly includes an interference fit member (IFM) which forms an interference fit with a carrier tube to reduce the tendency of the device to fall out of the carrier tube during handling and to provide for easy removal of the device when ready for use.

Claims

1. An intravascular device suitable for packaging in a package lumen defined by a package lumen wall, the intravascular device comprising:

an elongate shaft having a proximal portion; and

a hub assembly connected to the proximal portion of the elongate shaft, the hub assembly including an interference fit member (IFM) which is configured to form an interference fit with the package lumen wall when the intravascular device is disposed in the package lumen.

2. An intravascular device as in claim 1, wherein the IFM is fully disposed in the package lumen.

3. An intravascular device as in claim 1, wherein the interference fit establishes sufficient friction to resist gravitational and handling forces which may otherwise cause the intravascular device to fall out of the package lumen.

4. An intravascular device as in claim 3, wherein the friction created by the interference fit is sufficiently small to permit easy removal of the intravascular device from the package lumen.

5. An intravascular device as in claim 4, wherein package lumen wall comprises a carrier tube wall, and wherein the interference fit member (IFM) is configured to form an interference fit with the carrier tube wall.

6. An intravascular device as in claim 5, wherein the carrier tube wall has an inside surface, and wherein the IFM forms an interference fit with the inside surface of the carrier tube wall.

7. An intravascular device as in claim 6, wherein the carrier tube wall has an inside diameter, and wherein the IFM has an outside diameter greater than the inside diameter of the carrier tube wall.

8. An intravascular device as in claim 6, wherein the carrier tube wall has an inside cross-sectional dimension, and wherein the IFM has an outside cross-sectional dimension greater than the inside cross-sectional dimension of the carrier tube wall.

9. An intravascular device as in claim 5, wherein the carrier tube wall has an outside surface, and wherein the IFM forms an interference fit with the outside surface of the carrier tube wall.

10. An intravascular device as in claim 9, wherein the carrier tube wall has an outside diameter, and wherein the IFM has an inside diameter less than the outside diameter of the carrier tube wall.

11. An intravascular device as in claim 9, wherein the carrier tube wall has an outside cross-sectional dimension, and wherein the IFM has an inside cross-sectional dimension less than the outside cross-sectional dimension of the carrier tube wall.

12. An intravascular device as in claim 4, wherein the hub assembly includes a hub and a strain relief, and wherein the IFM is carried by the hub.

13. An intravascular device as in claim 4, wherein the hub assembly includes a hub and a strain relief, and wherein the IFM is carried by the strain relief.

14. An intravascular device as in claim 4, wherein the hub assembly includes a hub and a strain relief, and wherein the hub and the strain relief are integrally formed.

15. An intravascular device as in claim 4, wherein the hub assembly includes a hub and a strain relief, and wherein the hub and the strain relief are connected.

16. An intravascular device as in claim 15, wherein the connection between the hub and the strain relief comprises a bond.

17. An intravascular device as in claim 15, wherein the connection between the hub and the strain relief comprises a mechanical lock.

18. An intravascular device as in claim 4, wherein the IFM comprises one or more rings.

19. An intravascular device as in claim 4, wherein the IFM comprises one or more protrusions.

20. An intravascular device as in claim 4, wherein the IFM comprises a plurality of protrusions distributed about a circumference.

21. A hub assembly for an intravascular device suitable for packaging in a carrier tube, the hub assembly comprising an interference fit member (IFM) which is configured to form an interference fit with the carrier tube.

22. An intravascular device suitable for packaging in a package lumen defined by a package wall, the intravascular device comprising:

an elongate shaft having a proximal portion; and

a hub assembly connected to the proximal portion of the elongate shaft, the hub assembly including a means for forming an interference fit with the package wall when the intravascular device is disposed in the package lumen.

23. A packaged intravascular device, comprising:

a package having a package lumen defined by a package wall; and

an intravascular device disposed in the package lumen, the intravascular device comprising an elongate shaft having a proximal portion, a hub assembly connected to the proximal portion of the elongate shaft, the hub assembly including a means for forming an interference fit with the package wall.

24. An intravascular device suitable for packaging in a package lumen defined by a package lumen wall, the intravascular device comprising:

an elongate shaft having a proximal portion; and

an interference fit member (IFM) connected to the proximal portion of the elongate shaft, wherein the IFM is configured to form an interference fit with the package lumen wall when the intravascular device is disposed in the package lumen.
