Abstract
Abstract A tendon of artificial materials which are tolerated by the organism and of which the ends, which can be stitched, show good properties of adhesion to the tissues whilst the middle portion remains non-adherent. The artificial tendon, which is inextensible and is of a length which can be adjusted according to the needs of the surgeon, comprises a suturable textile strip which is such as to permit fibroblastic infiltration and which is sheathed at its longitudinal central portion in a flexible tube which is nonadherent to tissue.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
66 words
An artificial tendon consisting of a longitudinally inextensible textile strip which has a uniform porosity along its length and which has suturable end portions at each end thereof, said end portions permitting fibroblastic infiltration, and a longitudinally central portion between said end portions; and a flexible tube of a material which will not adhere to tissues sheathing said longitudinally central portion leaving said end portions exposed.
Claim 2
Dependent Claim
66 words
An artificial tendon consisting of a longitudinally inextensible textile strip which has a uniform porosity along its length and which has suturable end portions at each end thereof, said end portions permitting fibroblastic infiltration, and a longitudinally central portion between said end portions; and a flexible tube of a material which will not adhere to tissues sheathing said longitudinally central portion leaving said end portions exposed.
Claim 3
Dependent Claim
16 words
A tendon as claimed in claim 1, wherein said longitudinally central portion is impregnated with adhesive.
Claim 4
Dependent Claim
83 words
An artificial tendon consisting of a longitudinally inextensible textiLe strip having suturable end portions at each end thereof, said end portions permitting fibroblastic infiltration, and a longitudinally central portion between said end portions; a flexible tube of a material which will not adhere to tissues sheathing said longitudinal central portion leaving said end portions exposed; and two longitudinal side edges to said strip, at least the sheathed portion of said strip being wound up on itself widthwise starting from said two side edges.
Claim 5
Dependent Claim
83 words
An artificial tendon consisting of a longitudinally inextensible textiLe strip having suturable end portions at each end thereof, said end portions permitting fibroblastic infiltration, and a longitudinally central portion between said end portions; a flexible tube of a material which will not adhere to tissues sheathing said longitudinal central portion leaving said end portions exposed; and two longitudinal side edges to said strip, at least the sheathed portion of said strip being wound up on itself widthwise starting from said two side edges.
Claim 6
Dependent Claim
68 words
An artificial tendon consisting of a longitudinally inextensible textile strip having suturable end portions at each end thereof, said end portions permitting fibroblastic infiltration, and a longitudinally central portion between said end portions; and a flexible tube of a material which will not adhere to tissues sheathing said longitudinal central portion leaving said end portions exposed, said textile strip being independently slidable with respect to said sheathing tube.
Claim 7
Dependent Claim
68 words
An artificial tendon consisting of a longitudinally inextensible textile strip having suturable end portions at each end thereof, said end portions permitting fibroblastic infiltration, and a longitudinally central portion between said end portions; and a flexible tube of a material which will not adhere to tissues sheathing said longitudinal central portion leaving said end portions exposed, said textile strip being independently slidable with respect to said sheathing tube.
Claim 8
Dependent Claim
93 words
An artificial tendon consisting of a longitudinally inextensible textile strip having suturable end portions at each end thereof, said end portions permitting fibroblastic infiltration, and a longitudinally central portion between said end portions; a flexible tube of a material which will not adhere to tissues sheathing said longitidinal central portion leaving said end portions exposed; and an area of localized gluing adjacent only to the longitudinal centre of the interior of the tube with the end portions being free of gluing, the textile strip being adhered to said tube by said localized gluing.
Claim 9
Dependent Claim
93 words
An artificial tendon consisting of a longitudinally inextensible textile strip having suturable end portions at each end thereof, said end portions permitting fibroblastic infiltration, and a longitudinally central portion between said end portions; a flexible tube of a material which will not adhere to tissues sheathing said longitidinal central portion leaving said end portions exposed; and an area of localized gluing adjacent only to the longitudinal centre of the interior of the tube with the end portions being free of gluing, the textile strip being adhered to said tube by said localized gluing.
Claim 10
Dependent Claim
95 words
An artificial tendon consisting of a longitudinally inextensible textile strip having suturable end portions at each end thereof, said end portions permitting fibroblastic infiltration, and a longitudinally central portion between said end portions; a flexible tube of a material which will not adhere to tissues sheathing said longitudinal central portion leaving said end portions exposed; and an area of localized gluing adjacent only to the ends of the interior of said tube with the central portion between said ends being free of gluing, the textile strip being adhered to said tube by said localized gluing.
Claim 11
Dependent Claim
95 words
An artificial tendon consisting of a longitudinally inextensible textile strip having suturable end portions at each end thereof, said end portions permitting fibroblastic infiltration, and a longitudinally central portion between said end portions; a flexible tube of a material which will not adhere to tissues sheathing said longitudinal central portion leaving said end portions exposed; and an area of localized gluing adjacent only to the ends of the interior of said tube with the central portion between said ends being free of gluing, the textile strip being adhered to said tube by said localized gluing.
