- the present invention relates to an impersonable prosthetic system 1 in a human or animal body.
- the system 1 of the invention is therefore specifically designed to be implanted, that is to say introduced, inside a human or animal body, so as to be completely encompassed by said organism, without contact with outside, at the end of the surgical implantation procedure.
- a system comprises at least two independent elements connected or not together by construction.
- the system 1 comprises, on the one hand, a support 2 intended to come into contact with a biological tissue 4, and, on the other hand, an adhesive 3 intended to adhere said support 2 to the biological tissue 4.
- the support 2 may be made of a polymer-type material and used for example as implant site silicone or heart valve.
- Such an implantable prosthetic system 1 can thus be used in multiple applications, for example as parietal support, fixing means, retaining means, support means or reinforcement means.
- the shape, the size and the material of the support 2 are therefore variables according to the destination of the system 1 and the use made of it.
- Said adhesive 3 comprises, as an adhesive substance, at least one hydrocolloid.
- the hydrocolloid of [invention comprises particles of size between substantially one nanometer and one micrometer.
- said particles are not hydrosolutes and form in an aqueous medium a homogeneous solution.
- the hydrocolloid of the invention is chosen from natural hydrocolloids, that is to say that it is of natural origin.
- the natural hydrocoloid is of plant origin and is thus extracted from all or part of a plant
- the hydrocoiloid comes for example from a fruit, a seed or sap.
- the hydrocolo ⁇ de nature! is advantageously derived from a bacterial fermentation.
- hydrocoloid is obtained naturally and has not been chemically synthesized.
- a natural hydrocolloid has the advantage of being well tolerated by the body and limits the risks of intolerance that may exist with synthetic hydrocolioids.
- natural hydrocolloids are easily accessible, perfectly biocompatible and well known.
- said hydrocolio ⁇ cie is intended to form at least one weak bond with the biological tissue 4 for bonding said support 2 to said biological fabric 4.
- the adhesive function of the hydrocoiloid of the invention is, in fact, obtained thanks to its creation. weak bonds between said hydrocolloid and the tissue 4, especially between the hydrocoioid and the tissues 4 of the body.
- the weak bonds are ionic bonds, hydrogen bonds or Van der Walis that can be created naturally between two molecules in the presence, as opposed to covalent strong bonds that usually require a chemical reaction.
- the hydrocoiloid thus promotes the adhesion of the support 2 to the biological tissue 4 when a plurality of weak bonds is established between the hydrocoiloid and the tissue 4.
- said hydrocoiioid comprises at least one electrolyte group intended to form at least one weak bond with the biological tissue 4, so as to bond said support 2 to said biological tissue 4.
- an electrolyte group is considered to be preferably a tonic or ionizable group, ie a highly polar chemical group present in the molecule forming the hydrocolloid, said electrolyte being capable of forming weak bonds with biological tissues. , so as to allow a reliable and stable bonding of the support 2 on said fabrics 4,
- said hydrocolloid allows said support 2 to adhere to the biological tissue 4 advantageously with a bonding force substantially greater than five Newtons (N), preferably substantially greater than ten Newtons (N).
- N five Newtons
- the implementation of the weak links contributes very clearly to the strength of the bonding, notably by making it possible to obtain a bonding force greater than ten N, namely a sufficient bonding force to prevent any migration of the support after the laying of said support 2 on the fabric 4.
- Such a bonding force allows a stable, reliable and durable bonding of the support 2 on the fabric 4 for the duration of the treatment.
- the hydrocolloid ri ⁇ ve ⁇ tio ⁇ further comprises other properties promoting bonding.
- the viscosity of the hydrocolloid promotes a durable and reliable support 3 which does not migrate and remains in position on the tissues 4,
- This property makes it possible to obtain a prosthetic system 1 with an adhesive 3 which remains on the support 2, does not flow and does not dissolve in the presence of biological tissue 4, said adhesive 3 thus making it possible to effectively adhere said support 2 to the tissues 4.
- the weak bonds which are created mainly after the penetration of water tissue 4 into the molecule of the hydrocolloid, also form slowly, which causes a delayed sticky effect of said support 2 on the tissues 4.
- a retarded sticky effect mainly caused by the viscosity and hydration time of the hydrocolloid, allows the surgeon, who practices the prosthetic system 1, to have the possibility of repositioning said system 1 before the latter is definitively glued on the biological tissue 4. Indeed, before the bonding of the support 2 on the biological tissue 4 is actually effective, the surgeon has a time, more or less short depending on the vescoelastic properties and hydration of the hydrocolloid, possibly to change the replacement of the system 1, for example to better adjust the position ducHt system 1.
- the adhesive 3 comprises certain hydrocolloids in particular.
- the adhesive 3 comprises one or more of the following hydr ⁇ eolloids: carrageenan, gum tragacanth, pectin, geliane, xanthan, gum arabic and gum of guar.

- hydrocolloids Six plates of the same type of faille and material are each coated with one of the following hydrocolloids, said hydrocolloid being distributed in an identical and uniform amount on each of the six plates: carrageenan, gum tragacanth, pectin, gellan, xanthan and gum guar
- each coated plum is placed between two pieces of meat 6, simulating human body tissues, for example two beefsteaks.
- beefsteaks 6, 7 being of similar size, shape and weight.
- the plate 5 is positioned between the steaks 6, 7 in such a manner that a portion 5A of the plate 5 than to be able to be easily pulled to perform a measurement at the adhesion test, a pressure is applied so as to improve the bonding.
- the plate 5 is then left between the two beefsteaks 8, 7 during a rest period of several hours, preferably between 3 and 20 hours, the rest times being perfectly identical between the six plates ⁇ .
- a first end 8A of an alligator clip 8 is hooked at the portion of the plate 5A that protrudes and a second end 8B of the crocodile clip 8 to a dynamometer 9.

- hydrocolloids of the invention make it possible to obtain bonding forces greater than 5 N, preferably greater than 10 N. It is considered that the bonding of the support 2 to a fabric 4 is sufficient when the bonding force is at least between 10 and 15 N.
- carrageenan, gum tragacanth, pectin, ge ⁇ a ⁇ e and xanthan allow an effective and safe bonding of the prosthetic system 1 with bonding forces greater than 10 newtons.
- These hydrocoiloids are polyelectrolytes. Guar gum, which, in turn, is not polyoleolytic, allows a bonding force of 7 N which is much lower than that of polyelectrolyte hydrocoiioids. Since then; it can be concluded that the presence of several electrolytic groups in the hydrocoiloid improves the bonding. In addition, it is then possible, depending on the desired bonding strength, to adapt the composition of the adhesive by mixing several hydrocolloids with different collage.
- the adhesive 3 may advantageously comprise other ingredients which can contribute to the improvement of the adhesive effect of the support 2.
