Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
23 words
A textile surgical implant comprising an array of fibres, characterised in that the fibres forming the implant are placed in position by embroidery.
Claim 2
Dependent Claim
16 words
An implant as claimed in Claim 1, wherein the fibres are provided on a base cloth.
Claim 3
Dependent Claim
26 words
An implant as claimed in Claim 2, wherein the base cloth is removable from the fibres before or after location of the implant in a patient.
Claim 4
Dependent Claim
16 words
An implant as claimed in Claim 2 or Claim 3, wherein the base cloth is soluble.
Claim 5
Dependent Claim
29 words
An implant as claimed in Claim 2 or Claim 3, wherein the base cloth is adapted to degrade and/or be absorbed after the implant is implanted in a patient.
Claim 6
Dependent Claim
16 words
An implant as claimed in any preceding claim, wherein the fibres are arranged as a mesh.
Claim 7
Dependent Claim
18 words
An implant as claimed in Claim 6, wherein the mesh is reinforced in at least a part thereof.
Claim 8
Dependent Claim
16 words
An implant as claimed in any preceding claim, wherein said implant is of substantially triangular shape.
Claim 9
Dependent Claim
25 words
An implant as claimed in any of Claims 1 to 7, having fibres arranged to give greater stiffness in one direction than in another direction.
Claim 10
Dependent Claim
15 words
An implant as claimed in Claim 9, wherein the directions are substantially at right angles.
Claim 11
Dependent Claim
26 words
An implant as claimed in Claim 9 or Claim 10, formed as a tube having a radial stiffness greater than the stiffness in the axial direction.
Claim 12
Dependent Claim
28 words
An implant as claimed in Claim 11, wherein the tube is formed from a strip having fibres arranged in two directions, the strip being wound about an axis.
Claim 13
Dependent Claim
31 words
An implant as claimed in Claim 12, wherein the strip is wound in a plurality of turns and each turn of the strip, other than the first, overlaps the preceding turn.
Claim 14
Dependent Claim
21 words
An implant as claimed in any of Claims 10 to 13, wherein the tube is heat set to retain its shape.
Claim 15
Dependent Claim
19 words
An implant as claimed in any preceding claim and comprising one or more growth factors, angiogenic and neurogenic materials.
Claim 16
Independent Claim
23 words
A method of making an implant, said implant comprising an array of fibres, the method comprising placing the fibres in position by embroidery.
Claim 17
Dependent Claim
16 words
A method as claimed in Claim 16, wherein the fibres are placed on a base cloth.
Claim 18
Dependent Claim
21 words
A method as claimed in Claim 17, wherein the base cloth is removed after the fibres have been placed in position.
Claim 19
Dependent Claim
22 words
A method as claimed in Claim 18, wherein the base cloth is soluble and is removed by dissolving it in a solvent.
Claim 20
Dependent Claim
28 words
A method as claimed in Claim 18 or 19, wherein the base cloth is removed by degradation and/or absorption after the implant has been implanted in a patient.
Claim 21
Independent Claim
19 words
A method as claimed in any of Claims 16 to 20 when the fibres are arranged as a mesh.
Claim 22
Dependent Claim
18 words
A method as claimed in Claim 21 and comprising reinforcing the mesh in at least a part thereof.
Claim 23
Dependent Claim
29 words
A method as claimed in Claim 21 or Claim 22, wherein the fibres are placed in the mesh to give greater stiffness in one direction than in another direction.
Claim 24
Dependent Claim
23 words
A method as claimed in Claim 23, wherein fibres giving greater stiffness are placed at substantially right angles to fibres giving differential stiffness.
Claim 25
Dependent Claim
31 words
A method as claimed in Claim 23 or 24, wherein the array of fibres is formed as a tube having a radial stiffness greater than the stiffness in the axial direction.
Claim 26
Dependent Claim
28 words
A method as claimed in Claim 25, wherein the tube is formed from a strip having fibres arranged in two directions by winding the strip about an axis.
Claim 27
Dependent Claim
30 words
A method as claimed in Claim 26, wherein the strip is wound in a plurality of turns, each turn of the strip, other than the first, overlapping the preceding turn.
Claim 28
Independent Claim
21 words
A method as claimed in any of Claims 25 to 27, wherein the tube is heat set to retain its shape.
