Abstract
Abstract A radially expandable tubular prosthesis which allows for controlled expansion in a circumferential direction following implantation while limiting expansion in a longitudinal direction. The prosthesis is particularly suited to intraluminal implantation via a catheter and is also particularly suited for percutaneous implantation in children.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
82 words
A method for intraluminally repairing a damaged lumen in a patient comprising: delivering an expandable prosthesis to a site of damage in said lumen, said prosthesis being formed from a tubular substantially fluid-impermeable polymeric fabric having yams which extend around the circumference of said fabric and which are sufficiently undrawn to allow for controlled inelastic radial expansion upon the application of a preselected radial force thereto; and delivering an internal preselected radial force to said prosthesis sufficient to inelastically expand said prosthesis.
Claim 2
Independent Claim
82 words
A method for intraluminally repairing a damaged lumen in a patient comprising: delivering an expandable prosthesis to a site of damage in said lumen, said prosthesis being formed from a tubular substantially fluid-impermeable polymeric fabric having yams which extend around the circumference of said fabric and which are sufficiently undrawn to allow for controlled inelastic radial expansion upon the application of a preselected radial force thereto; and delivering an internal preselected radial force to said prosthesis sufficient to inelastically expand said prosthesis.
Claim 3
Dependent Claim
14 words
The method of claim 1, wherein said prosthesis is expanded via a balloon catheter.
Claim 4
Dependent Claim
17 words
The method of claim 1, wherein said prosthesis includes means for securing said prosthesis to said lumen.
Claim 5
Dependent Claim
17 words
The method of claim 3, further comprising the step of securing said expandable prosthesis to said lumen.
Claim 6
Dependent Claim
12 words
The method of claim 1, wherein said lumen is a blood vessel.
Claim 7
Dependent Claim
19 words
The method according to claim 1, wherein said prosthesis is delivered intraluminally to said damaged lumen via a catheter.
Claim 8
Dependent Claim
26 words
The method of claim 6, wherein said prosthesis is initially sized for intraluminal delivery via said catheter without need for rolling or bunching of said prosthesis.
Claim 9
Dependent Claim
22 words
The method according to claim 6, wherein said prosthesis is expanded until its diameter substantially conforms to that of said damaged lumen.
Claim 10
Dependent Claim
21 words
The method according to claim 1, wherein said patient is a child, and said prosthesis is surgically implanted in said child.
Claim 11
Dependent Claim
39 words
The method according to claim 9, wherein said prosthesis is expanded following a period of growth in said child until its diameter substantially conforms to that of a connecting host lumen which has experienced a period of circumferential growth.
