Abstract
Abstract A textile surgical implant includes a base cloth, and an array of fibers provided on the base cloth. The base cloth is removable from the fibers before or after the location of the implant in a patient. A method of making a textile surgical implant is further disclosed. The method includes the step of placing an array of fibers on a base cloth by embroidery. The base cloth is removable from the fibers before or after the implant is implanted.

Dependent Claim
30 words
A textile surgical implant comprising a bioabsorbable base cloth having an embroidered mesh structure disposed thereon, said base cloth being absorbed after the location of the implant in a patient.
Claim 3
Dependent Claim
13 words
An implant as claimed in claim 1, wherein the base cloth is soluble.
Claim 4
Dependent Claim
26 words
An implant as claimed in claim 1, wherein the base cloth is made from materials which will degrade after the implant is implanted in a patient.
Claim 5
Dependent Claim
20 words
An implant as claimed in claim 1, wherein the embroidered mesh structure is reinforced in at least a part thereof.
Claim 6
Dependent Claim
15 words
An implant as claimed in claim 1, wherein said implant is of substantially triangular shape.
Claim 7
Dependent Claim
25 words
An implant as claimed in claim 1, said embroidered mesh structure having fibres arranged to give greater stiffness in one direction than in another direction.
Claim 8
Dependent Claim
46 words
An implant as claimed in claim 6, comprising first fibres of a greater stiffness extending in one direction, and second fibres of a lesser stiffness extending in a second direction, the first and second directions of the fibres being substantially at right angles to one another.
Claim 9
Dependent Claim
17 words

Claim 10
Dependent Claim
23 words
An implant as claimed in claim 6 formed as a tube having a radial stiffness greater than the stiffness in the axial direction.
Claim 11
Dependent Claim
28 words
