Abstract
Abstract A radially self-expanding implantable intraluminal device formed from a hollow tubular braid. The intraluminal device may be used in a variety of medical procedures which require a passageway to be maintained in an open position or which require reinforcement, support or a bypass conduit such as in blood vessels weakened by disease. The intraluminal device is longitudinally expanded or radially collapsed for ease of insertion into a lumen and upon alignment within the lumen, the intraluminal device radially self-expands to come into intimate contact with the inner surface of the lumen.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
86 words
A method for repositioning an implanted radially self-expanding intraluminal hollow thermoplastic tubular braid comprising the step of: introducing a guide wire having on its distal end at least one finger-like member for grasping only one end of the implanted thermoplastic braid so that the implanted thermoplastic braid may be repositioned within a lumen wherein the braid is made from a thermoplastic material which is heat-set for a sufficient time and temperature to effectuate a permanent memory in an expanded state and is a three dimensional braid.
Claim 2
Independent Claim
86 words
A method for repositioning an implanted radially self-expanding intraluminal hollow thermoplastic tubular braid comprising the step of: introducing a guide wire having on its distal end at least one finger-like member for grasping only one end of the implanted thermoplastic braid so that the implanted thermoplastic braid may be repositioned within a lumen wherein the braid is made from a thermoplastic material which is heat-set for a sufficient time and temperature to effectuate a permanent memory in an expanded state and is a three dimensional braid.
Claim 3
Dependent Claim
14 words
A method as described in claim 1, wherein the finger-like member is selectively positionable.
Claim 4
Dependent Claim
70 words
The method of claim 1, wherein the introducing step further comprises: grasping the braid with the finger-like member; applying a radially inward force to said braid whereby its diameter decreases to facilitate its being moved within the vessel; repositioning the braid at a location within the vessel; expanding said braid radially until its diameter substantially conforms to the diameter of said vessel whereby said braid is substantially anchored in position.
Claim 5
Independent Claim
167 words
A method for substantially repairing a damaged vessel comprising: providing a prosthesis in the form of an implantable radially self-expanding intraluminal hollow tubular braid; applying a radially inward force to said prosthesis whereby its diameter decreases to facilitate entry of said prosthesis into said vessel; delivering said prosthesis intraluminally to a site of damage in said vessel; expanding said prosthesis radially until its diameter substantially conforms to the diameter of said vessel whereby said prosthesis is substantially anchored in position; introducing a guide wire having on its distal end at least one finger-like member; grasping only one end of the prosthesis with the finger-like member; applying a radially inward force to said prosthesis whereby its diameter decreases to facilitate its being moved within the vessel; repositioning the prosthesis at a location within the vessel; and releasing the prosthesis from the finger-like member so that said prosthesis expands radially until its diameter substantially conforms to the diameter of said vessel whereby said prosthesis is substantially anchored in position.
Claim 6
Independent Claim
167 words
A method for substantially repairing a damaged vessel comprising: providing a prosthesis in the form of an implantable radially self-expanding intraluminal hollow tubular braid; applying a radially inward force to said prosthesis whereby its diameter decreases to facilitate entry of said prosthesis into said vessel; delivering said prosthesis intraluminally to a site of damage in said vessel; expanding said prosthesis radially until its diameter substantially conforms to the diameter of said vessel whereby said prosthesis is substantially anchored in position; introducing a guide wire having on its distal end at least one finger-like member; grasping only one end of the prosthesis with the finger-like member; applying a radially inward force to said prosthesis whereby its diameter decreases to facilitate its being moved within the vessel; repositioning the prosthesis at a location within the vessel; and releasing the prosthesis from the finger-like member so that said prosthesis expands radially until its diameter substantially conforms to the diameter of said vessel whereby said prosthesis is substantially anchored in position.
Claim 7
Dependent Claim
17 words
The method according to claim 4, further comprising the step of securing said prosthesis to said vessel.
Claim 8
Dependent Claim
37 words
The method according to claim 4, wherein said prosthesis is radially self-expanding whereby said prosthesis radially expands to substantially conform with the diameter of said vessel following intraluminal placement of said prosthesis at the site of damage.
Claim 9
Dependent Claim
57 words
The method according to claim 4, wherein the providing step provides an implantable intraluminal device including a radially self-expanding hollow tubular braid, wherein the device is made from a thermoplastic material which is heat-set for a sufficient time and temperature to effectuate a permanent memory in an expanded state and wherein the braid is a three-dimensional braid.
