Abstract
Abstract A guided protector for a stent delivery assembly including an arbor disposed generally in the center of a sleeve. The distal end of the arbor is joined to the sleeve using a variety of joining methods including a friction fit and plastic welding. In a preferred embodiment, the inside diameter of the sleeve is larger than the outside diameter of the stent which is being protected.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
75 words
A guided protector for a stent delivery assembly including a stent disposed therein, said protector comprising: a sleeve having a proximal portion, a distal portion and a lumen extending through at least a portion thereof; an arbor having an outside diameter, a proximal portion and a distal portion, at least a portion of the arbor disposed within said lumen; and means for disposing the arbor generally in the center of the lumen of the sleeve.
Claim 2
Dependent Claim
75 words
A guided protector for a stent delivery assembly including a stent disposed therein, said protector comprising: a sleeve having a proximal portion, a distal portion and a lumen extending through at least a portion thereof; an arbor having an outside diameter, a proximal portion and a distal portion, at least a portion of the arbor disposed within said lumen; and means for disposing the arbor generally in the center of the lumen of the sleeve.
Claim 3
Dependent Claim
22 words
The guided protector of claim 1, wherein the means for disposing the arbor is formed on the distal portion of said arbor.
Claim 4
Dependent Claim
27 words
The guided protector of claim 1, wherein the distal portion of the arbor forms a friction fit with an inside wall of the sleeve forming the lumen.
Claim 5
Dependent Claim
29 words
The guided protector of claim 1, wherein the stent has an outside diameter and the lumen diameter of the sleeve is larger than the outside diameter of the stent.
Claim 6
Dependent Claim
29 words
The guided protector of claim 1, wherein the stent delivery assembly has an inner lumen, wherein, in use, at least a portion of the arbor is slidably disposed therein.
Claim 7
Dependent Claim
24 words
The guided protector of claim 5, wherein the stent delivery lumen diameter is equal to or greater than the outside diameter of the arbor.
Claim 8
Dependent Claim
24 words
The guided protector of claim 1, wherein a portion of the proximal portion of the arbor extends beyond the proximal portion of the sleeve.
Claim 9
Dependent Claim
22 words
The guided protector of claim 2, wherein the distal portion of the arbor is generally formed into the slope of an eyelet.
Claim 10
Dependent Claim
22 words
The guided protector of claim 2, wherein the distal portion of the arbor is generally formed into the shape of a hook.
Claim 11
Dependent Claim
22 words
The guided protector of claim 2, wherein the distal portion of the arbor is generally formed into the shape of a coil.
Claim 12
Dependent Claim
23 words
The guided protector of claim 2, wherein the distal portion of the arbor is generally formed into the shape of a conical coil.
Claim 13
Dependent Claim
78 words
A guided protector for a stent delivery assembly including a stent, comprising: a sleeve having a proximal portion, a distal end, and a lumen extending through at least a portion thereof; and an arbor having a proximal portion and a distal portion, said proximal portion disposed generally in the center of the lumen of the sleeve and extending longitudinally therein and said distal portion generally encapsulated within the distal portion of the sleeve to fix the arbor therein.
Claim 14
Dependent Claim
78 words
A guided protector for a stent delivery assembly including a stent, comprising: a sleeve having a proximal portion, a distal end, and a lumen extending through at least a portion thereof; and an arbor having a proximal portion and a distal portion, said proximal portion disposed generally in the center of the lumen of the sleeve and extending longitudinally therein and said distal portion generally encapsulated within the distal portion of the sleeve to fix the arbor therein.
Claim 15
Dependent Claim
27 words
The guided protector of claim 12, wherein the stent has an outside diameter and the sleeve lumen diameter is greater than the outside diameter of the stent.
Claim 16
Dependent Claim
24 words
The guided protector of claim 12, wherein the stent delivery assembly has an inner lumen, wherein, in use, the arbor is slidably disposed therein.
Claim 17
Dependent Claim
26 words
The guided protector of claim 12, wherein the stent delivery assembly lumen has a diameter greater than or equal to the outside diameter of the arbor.
Claim 18
Dependent Claim
24 words
The guided protector of claim 12, wherein a portion of the proximal portion of the arbor extends beyond the proximal portion of the sleeve.
Claim 19
Independent Claim
102 words
A method for protecting a stent delivery assembly having an inner lumen and a stent comprising the steps of: providing a guided protector, said guided protector including a sleeve having a lumen extending through at least a portion thereof and an arbor disposed within at least a portion of the lumen; coaxially positioning the distal end of the arbor proximate the inner lumen of a stent delivery assembly; inserting the proximal end of the arbor into the inner lumen of the stent delivery assembly; and moving the guided protector in a proximal direction until the stent is substantially covered by the sleeve.
Claim 20
Independent Claim
102 words
A method for protecting a stent delivery assembly having an inner lumen and a stent comprising the steps of: providing a guided protector, said guided protector including a sleeve having a lumen extending through at least a portion thereof and an arbor disposed within at least a portion of the lumen; coaxially positioning the distal end of the arbor proximate the inner lumen of a stent delivery assembly; inserting the proximal end of the arbor into the inner lumen of the stent delivery assembly; and moving the guided protector in a proximal direction until the stent is substantially covered by the sleeve.
Claim 21
Dependent Claim
30 words
The method of claim 17, wherein the stent has an outside diameter and the inside diameter of the sleeve is larger than the outside diameter of the stent delivery assembly.
Claim 22
Dependent Claim
43 words
The method of claim 17, wherein the stent delivery assembly has an inner lumen with an inside diameter and the outside diameter of the arbor is smaller than or equal to the inside diameter of the inner lumen of the stent delivery assembly.
Claim 23
Dependent Claim
20 words
The method of claim 17, wherein the proximal end of the arbor extends beyond the proximal end of the sleeve.
