Abstract
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 Analysis
Total Claims: 21
Claim 1
Independent Claim
55 words
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.
Claim 2
Independent Claim
55 words
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.
Claim 3
Dependent Claim
17 words
The system of claim 1 , wherein at least one detent engages the slot with compressive forces.
Claim 4
Dependent Claim
19 words
The system of claim 2 , wherein the detent is formed from a grommet having an inwardly bent end.
Claim 5
Dependent Claim
15 words
The system of claim 2 , wherein the detent is formed from a spring-loaded appendage.
Claim 6
Dependent Claim
19 words
The system of claim 1 , wherein the slot is formed by a localized grind in the guide wire.
Claim 7
Dependent Claim
19 words
The system of claim 1 , wherein the slot is formed between two bushings adhered to the guide wire.
Claim 8
Dependent Claim
20 words
The system of claim 1 , wherein the slot is formed within a single bushing adhered to the guide wire.
Claim 9
Dependent Claim
30 words
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.
Claim 10
Independent Claim
95 words
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.
Claim 11
Independent Claim
95 words
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.
Claim 12
Dependent Claim
18 words
The system of claim 9 , further comprising: a compressive strap around the at least two spring-loaded appendages.
Claim 13
Dependent Claim
18 words
The system of claim 9 , wherein the second bushing on the guide wire has a proximal taper.
Claim 14
Dependent Claim
21 words
The system of claim 9 , further comprising: a sleeve connecting the at least two appendages to the intraluminal treatment device.
Claim 15
Dependent Claim
19 words
The system of claim 9 , wherein the appendages include a U-shaped end in contact with the guide wire.
Claim 16
Dependent Claim
21 words
The system of claim 9 , wherein the intraluminal device and spring-loaded appendages are collapsed for delivery and expanded for treatment.
Claim 17
Independent Claim
72 words
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.
Claim 18
Independent Claim
72 words
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.
Claim 19
Dependent Claim
24 words
The system of claim 15 , wherein the recessed portion of the guide wire is formed between two bushings adhered to the guide wire.
Claim 20
Dependent Claim
26 words
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.
Claim 21
Dependent Claim
23 words
The system of claim 15 , further comprising a bushing on the guide wire located at the distal end of the recessed portion.
