Abstract

A hub system comprising, in combination: a luer further comprising a luer channel, configured to accommodate a selected device, said luer channel further comprising a segment extending through an extension of said luer; and a nose further comprising a nose channel configured to selectively couple with said extension, wherein the inner diameter of at least a portion of said nose channel is less than the outer diameter of the extension. A method of using the same to secure a device within said system.

Claims

1. A hub system comprising, in combination:

a luer further comprising a luer channel, configured to accommodate a selected device, said luer channel further comprising a segment extending through an extension of said luer; and

a nose further comprising a nose channel configured to selectively couple with said extension, wherein said nose channel is configured to compress said extension when said nose channel is coupled to said extension.

2. The hub system of claim 1, further comprising a gasket configured to fit between at least a portion of said luer and at least a portion of said nose.

3. The hub system of claim 1, wherein said luer channel connects a proximal opening disposed at a proximal end of said luer and a distal opening disposed at a distal end of said luer.

4. The hub system of claim 3, wherein said luer channel is substantially tapered from said proximal opening to said segment.

5. The hub system of claim 1, wherein said extension is compressible.

6. The hub system of claim 1, wherein said segment is configured to have a compressed state and an uncompressed state, corresponding to a state of said extension.

7. The hub system of claim 6, wherein said segment is configured to allow travel of said selected device while in said uncompressed state.

8. The hub system of claim 6, wherein said segment is configured to restrict travel of said selected device while in said compressed state.

9. The hub system of claim 1, wherein said selected device includes at least one of a guidewire, an over-the-wire or rapid exchange catheter, a microcatheter, a balloon, a stent, a coil, and a device for vascular treatment.

10. The hub system of claim 1, wherein said luer further comprises a luer interface configured to interface with a nose interface of said nose and configured to facilitate coupling of said luer to said nose.

11. The hub system of claim 1, wherein said nose further comprises a nose interface configured to interface with a luer interface of said luer and configured to facilitate coupling of said nose to said luer.

12. A method, comprising, in combination:

placing a selected device within a luer channel of a luer, including within a segment of said luer channel;

placing said selected device within a gasket;

placing said selected device within a nose channel of a nose, such that said luer and said nose are substantially aligned along a length of the selected device, with a distal end of said luer facing a proximal end of said nose, and with said gasket disposed between said luer and said nose;

advancing said selected device through said luer and said nose to a desired location; and

coupling said nose to said luer, whereby mobility of said selected device is restricted within at least one of said luer and said nose by compressing said segment onto a at least a portion of said selected device.

13. The method of claim 12, wherein said desired location corresponds to a location inside an anatomy of a body.

14. The method of claim 12, wherein coupling said nose to said luer includes advancing an extension within said nose channel through a proximal opening of said nose.

15. The method of claim 12, wherein coupling said nose to said luer includes causing said distal end of said luer to overlap with said proximal end of said nose.

16. The method of claim 12, wherein coupling said nose to said luer includes operating a luer interface relative to a nose interface.

17. The method of claim 12, further comprising de-coupling said nose from said luer, whereby mobility of said selected device is restored.

18. A kit, comprising, in combination:

a luer further comprising a luer channel, said luer channel further comprising a segment extending through an extension of said luer;

a nose further comprising a nose channel configured to selectively couple with said extension, wherein an inner diameter of at least a portion of said nose channel is less than an outer diameter of said extension, such that said nose channel is configured to compress said extension when said nose channel is coupled to said extension;

a gasket configured to fit between at least a portion of said luer and at least a portion of said nose; and

instructions for use.

19. The kit of claim 18, further comprising a selected device configured to be advanced within at least one of said luer channel and said nose channel.

20. The kit of claim 18, wherein a selected device includes at least one of a guidewire, an over-the-wire or rapid exchange catheter, a microcatheter, a balloon, a stent, a coil, and a device for vascular treatment.
