Abstract
Abstract An embodiment of a placement catheter assembly ( 2 ) comprises an inner shaft ( 10 ) movably housed within a hollow outer shaft ( 8 ). A radially-expansible endoluminal prosthesis ( 6 ) is mounted about the inner shaft between the distal ends of the inner and outer shafts. Distal and proximal end release elements ( 22/28, 16/34 ), such as pull wires, are carried by the inner and outer shafts and releasably secure the prosthesis to the inner and outer shafts. The prosthesis in the radially contracted state and the distal and proximal end release elements together have a maximum diameter which is at most about equal to the diameter of the distal part ( 48 ) of the outer shaft to facilitate placement of the prosthesis.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
201 words
A placement catheter assembly comprising: a hollow outer shaft comprising a distal part, said distal part comprising a distal end; an inner shaft, having a distal end, movably housed within the outer shaft; a radially-expansible endoluminal prosthesis mounted about the inner shaft between the distal ends of the inner and outer shafts; a distal end attachment device comprising a distal end release element carried by the inner shaft and releasably securing the prosthesis to the inner shaft; a proximal end attachment device comprising: an elongate, tubular proximal end release element holder extending axially away from the distal end of the outer shaft; a proximal end release element carried by the outer shaft with a part of the proximal end release element passing through the holder; the holder having a side opening from which a portion of the proximal end release element extends to engage the prosthesis thereby releasably securing the prosthesis to the outer shaft; and the prosthesis in a radially contracted state and the distal and proximal end release elements together having a maximum diameter which is at most about equal to the diameter of the distal part of the outer shaft so that placement of the prosthesis is facilitated.
Claim 2
Dependent Claim
201 words
A placement catheter assembly comprising: a hollow outer shaft comprising a distal part, said distal part comprising a distal end; an inner shaft, having a distal end, movably housed within the outer shaft; a radially-expansible endoluminal prosthesis mounted about the inner shaft between the distal ends of the inner and outer shafts; a distal end attachment device comprising a distal end release element carried by the inner shaft and releasably securing the prosthesis to the inner shaft; a proximal end attachment device comprising: an elongate, tubular proximal end release element holder extending axially away from the distal end of the outer shaft; a proximal end release element carried by the outer shaft with a part of the proximal end release element passing through the holder; the holder having a side opening from which a portion of the proximal end release element extends to engage the prosthesis thereby releasably securing the prosthesis to the outer shaft; and the prosthesis in a radially contracted state and the distal and proximal end release elements together having a maximum diameter which is at most about equal to the diameter of the distal part of the outer shaft so that placement of the prosthesis is facilitated.
Claim 3
Dependent Claim
32 words
The placement catheter assembly according to claim 1 wherein the outer shaft defines a first lumen, which houses the proximal end release element, and a second lumen, which houses the inner shaft.
Claim 4
Dependent Claim
27 words
The placement catheter assembly according to claim 2 wherein the inner shaft defines a third lumen, which houses the distal end release element, and a fourth lumen.
Claim 5
Dependent Claim
16 words
The placement catheter assembly according to claim 3 wherein said fourth lumen comprises a guidewire lumen.
Claim 6
Dependent Claim
22 words
The placement catheter assembly according to claim 2 wherein the inner shaft defines a third lumen housing the distal end release element.
Claim 7
Dependent Claim
52 words
The placement catheter assembly according to claim 5 further comprising an opening, formed in the inner shaft spaced apart from the distal end of the inner shaft, which opens into the third lumen to permit a portion of the distal end release element to extend through the opening and engage the prosthesis.
Claim 8
Dependent Claim
42 words
The placement catheter assembly according to claim 1 wherein the outer shaft defines a first lumen, which houses the proximal end release element, and a second lumen, which houses the inner shaft, a portion of the holder extending into the first lumen.
Claim 9
Dependent Claim
15 words
The placement catheter assembly according to claim 1 wherein the holder is a flexible tube.
Claim 10
Dependent Claim
24 words
The placement catheter assembly according to claim 1 further comprising a remotely visualizable band secured to the bolder, the band circumscribing the inner shaft.
Claim 11
Dependent Claim
19 words
The placement catheter assembly according to claim 1 wherein the distal and proximal end release elements comprise pull wires.
Claim 12
Dependent Claim
16 words
The placement catheter assembly according to claim 1 wherein the prosthesis is a coiled endoluminal prosthesis.
Claim 13
Dependent Claim
18 words
The placement catheter assembly according to claim 11 wherein the coiled endoluminal prosthesis is a coiled stent graft.
