Abstract
Abstract A prosthetic fabric comprises a sheet textile structure capable of two different shapes, one being a flat, unfolded arrangement and the other being an ordered, gathered arrangement, and at least one continuous filiform element having two free gripping ends. The continuous filiform element is connected to the sheet structure by a plurality of catching points distributed over a surface of the sheet, along and on either side of a neutral axis that is parallel to one of the principal dimensions of the sheet. The structure of the fabric is such that pulling on the two gripping ends of the continuous filiform element generates the folded arrangement wherein the sheet is ordered transversely and on either side of the neutral axis and pulling on only one gripping end of the continuous filiform element extracts the continuous filiform element from the sheet.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
200 words
A prosthetic fabric comprising a sheet with a biocompatible, implantable textile structure conformable from a flat arrangement to a folded arrangement having a memory of the flat arrangement, and at least a continuous filiform element joined onto the textile structure of the sheet while also remaining free to slide with respect to the sheet, the continuous filiform element having first and second free gripping ends, wherein the continuous filiform element defines in the flat arrangement of the sheet a continuous line along at least on dimension of said sheet, wherein the continuous filiform element in joined onto the sheet with a plurality of catching points distributed along said continuous line, wherein the catching points are distributed over a surface of the sheet, along and on each side of a neutral axis, parallel to one of the principal dimensions of said sheet, wherein pulling on the two gripping ends of the continuous filiform element generates the folded arrangement of the sheet, ordered transversely and on each side of said neutral axis, and wherein pulling one gripping end of the continuous filiform element in either the flat arrangement or the folded arrangement of the sheet allows extraction of the continuous filiform element.
Claim 2
Dependent Claim
200 words
A prosthetic fabric comprising a sheet with a biocompatible, implantable textile structure conformable from a flat arrangement to a folded arrangement having a memory of the flat arrangement, and at least a continuous filiform element joined onto the textile structure of the sheet while also remaining free to slide with respect to the sheet, the continuous filiform element having first and second free gripping ends, wherein the continuous filiform element defines in the flat arrangement of the sheet a continuous line along at least on dimension of said sheet, wherein the continuous filiform element in joined onto the sheet with a plurality of catching points distributed along said continuous line, wherein the catching points are distributed over a surface of the sheet, along and on each side of a neutral axis, parallel to one of the principal dimensions of said sheet, wherein pulling on the two gripping ends of the continuous filiform element generates the folded arrangement of the sheet, ordered transversely and on each side of said neutral axis, and wherein pulling one gripping end of the continuous filiform element in either the flat arrangement or the folded arrangement of the sheet allows extraction of the continuous filiform element.
Claim 3
Dependent Claim
44 words
The fabric as claimed in claim 1, in which the textile structure of the sheet consists of an interlacing of warp threads and of weft threads that forms meshes, wherein the neutral axis lies parallel to the warp threads or to the weft threads.
Claim 4
Dependent Claim
19 words
The fabric as claimed in claim 2, wherein the neutral axis passes substantially through the middle of the sheet.
Claim 5
Dependent Claim
80 words
The fabric as claimed in claim 3, wherein the catching points define, in pairs, transverse segments arranged perpendicular to the neutral axis and distributed along the neutral axis, wherein a first transverse segment is joined at an end thereof to the first gripping end, a last transverse segment is joined at an end thereof with the second gripping end, and remaining transverse segments are joined at ends thereof to each other alternately by longitudinal segments parallel to the neutral axis.
Claim 6
Dependent Claim
36 words
The fabric as claimed in claim 4, wherein the catching points define two lines of connection with the textile structure of the sheet, these lines being parallel to and on each side of the neutral axis.
Claim 7
Dependent Claim
19 words
The fabric as claimed in claim 5, wherein the lines of connection are substantially equidistant from the neutral axis.
Claim 8
Dependent Claim
15 words
The fabric as claimed in claim 4, wherein the transverse segments are equal in length.
Claim 9
Dependent Claim
15 words
The fabric as claimed in claim 4, wherein the longitudinal segments are equal in length.
Claim 10
Dependent Claim
47 words
The fabric as claimed in claim 1, wherein two opposed filiform elements each describe, when flat, approximately a sinusoid or a zigzag, on either side of the neutral axis, the two sinusoids or zigzags crossing each other in a plurality of points lying on the neutral axis.
Claim 11
Dependent Claim
26 words
The fabric as claimed in claim 9, wherein the two opposed filiform elements form a geometrical figure which is symmetrical with respect to the neutral axis.
Claim 12
Dependent Claim
23 words
The fabric as claimed in claim 9, wherein each opposed filiform element is connected at both ends to two free gripping ends, respectively.
Claim 13
Dependent Claim
30 words
The fabric as claimed in claim 1, wherein the filiform element and the sheet are designed to allow extraction of the filiform element, in the folded arrangement of the sheet.
Claim 14
Dependent Claim
14 words
The fabric as claimed in claim 4, wherein the transverse segments have different lengths.
Claim 15
Dependent Claim
14 words
The fabric as claimed in claim 4, wherein the longitudinal segments have different lengths.
Claim 16
Dependent Claim
27 words
The fabric as claimed in claim 1, wherein the fabric has a size capable of passing through a trocar and of being deployed in a peritoneal cavity.
Claim 17
Dependent Claim
25 words
The fabric as claimed in claim 1, wherein the two gripping ends of the continuous filiform element are located at opposite ends of the fabric.
