Abstract

A system for delivery of an intraluminal treatment device is provided. A guide wire having a recessed portion is combined with an intraluminal treatment device having a mechanism for securing the intraluminal treatment device to the recessed portion. This system permits an intraluminal treatment device to be secured to the guide way prior to or after the intraluminal delivery of the guide wire.

Claims

1. A system for intraluminal delivery of an embolic cage, comprising:

a guide wire having a distal end and a proximal end;

a slot on the guide wire located near the distal end;

an embolic cage slidably disposed over the guide wire;

at least one detent on the embolic cage configured to securedly engage the slot.

2. The system of claim 1, wherein at least one detent engages the slot with compressive forces.

3. The system of claim 2, wherein the detent is formed from a grommet having an inwardly bent end.

4. The system of claim 2, wherein the detent is formed from a spring-loaded appendage.

5. The system of claim 1, wherein the slot is formed by a localized grind in the guide wire.

6. The system of claim 1, wherein the slot is formed between two bushings adhered to the guide wire.

7. The system of claim 1, wherein the slot is formed within a single bushing adhered to the guide wire.

8. The system of claim 1, wherein the secure engagement between the detent and slot allows for rotation but not translation of the embolic cage relative to the guide wire.

9. A system for attaching an intraluminal device to a guide wire, comprising:

a guide wire having a distal tip;

a first bushing on the guide wire located near the distal tip;

a second bushing on the guide wire located proximal to the first bushing;

an intraluminal device slidably disposed on the guide wire; and

at least two spring-loaded appendages attached to the intraluminal device in compressive contact with the guide wire,

whereby the appendages prevent sliding of the intraluminal device while the appendages contact the guide wire between the first bushing and the second bushing.

10. The system of claim 9, further comprising:

a compressive strap around the at least two spring-loaded appendages.

11. The system of claim 9, wherein the second bushing on the guide wire has a proximal taper.

12. The system of claim 9, further comprising:

a sleeve connecting the at least two appendages to the intraluminal treatment device.

13. The system of claim 9, wherein the appendages include a U-shaped end in contact with the guide wire.

14. The system of claim 9, wherein the intraluminal device and spring-loaded appendages are collapsed for delivery and expanded for treatment.

15. A system for securing an intraluminal treatment device to a guide wire, comprising:

a guide wire having a recessed portion;

an expandable intraluminal treatment device having a detent in compressive contact around the guide wire;

a delivery catheter disposed over the intraluminal treatment device and the guide wire; and

the delivery catheter is configured to slide the treatment device over the guide wire until the detent is positioned over the recessed portion.

16. The system of claim 15, wherein the recessed portion of the guide wire is formed between two bushings adhered to the guide wire.

17. The system of claim 15, wherein the inner diameter of the delivery catheter is sized to prevent the delivery catheter from advancing beyond the bushings.

18. The system of claim 15, further comprising a bushing on the guide wire located at the distal end of the recessed portion.

19. A delivery system for an intraluminal treatment device, comprising:

a guide wire;

an intraluminal treatment device disposed over the guide wire;

at least one detent attached to the treatment device and biased to compress against the guide wire;

an inner catheter disposed between the detent and the guide wire for delivery; and

an outer catheter disposed over the intraluminal treatment device and configured to advance the intraluminal treatment device distally along the guide wire.

20. The delivery system of claim 19, further comprising:

multiple detents attached to the treatment device biased to compress against the guide wire; and

a compressive strap wrapped around the detents biasing the detents against the guide wire.

21. The delivery system of claim 19, wherein the detent is formed of a grommet with inwardly bent ends.

22. The delivery system of claim 19, wherein the intraluminal treatment device is prevented from further translation once the inner catheter is withdrawn and the detent is compressed against the guide wire.
