Definitions
- the present invention is part of the technique of implantable surgical implants made of adhesive textiles intended for the parietal repair of the human organism.
- the applications fall within the field of the treatment of hernias and abdominal eventrations, as well as the treatment of urinary incontinence and vaginal and rectal prolapse, plasties of the spinal and cerebral dura by patches, pericardium plasties and tissue repairs soft in orthopedics.
- the parietal repair surgical implants have been fixed either by stapling, by sutures, or by gluing.
- the fixation is carried out by the surgeon using an independent medical device: stapler, wires, sprayer. It is possible not to fix the implant, but the risk of mobility of the parietal implant is then high.
- the staples as described in international patent application WO 03/034925, or the surgical sutures, offer good fixation of the implant on the tissues, whether they are biocompatible, absorbable or not.
- stapling remains traumatic, a nerve ending can be pinched and post-operative pain sometimes felt.
- Secondary adhesions may appear on the staples, especially for the venting plates placed intraperitoneally.
- the realization of stitches has the disadvantage of being a long operation.
- Surgical adhesives for bonding an implant to human tissue such as fibrin and cyanoacrylate adhesives, are already known. Fibrin-based adhesives, which are completely biodegradable, are only very slightly adhesive compared to cyanoacrylate adhesives.
- Fibrin glues are applied by the surgeon to the implant and require a long and restrictive advance preparation for the operating theater nurse.
- Cyanoacrylate adhesives have strong adhesion, but necrotize living tissue or burn it by exothermic reaction.
- the rapid hardening of the cyanoacrylate is an obstacle in the use, the repositioning of the plate after contact is no longer possible. Biocompatibility is not proven, the exothermic hardening reaction releasing certain toxic molecules.
- the main disadvantage of these adhesives remains the difficulty of dosing and application at the time of use, the adhesive having to be deposited on the plate, under the conditions of intervention in the operating room.
- the invention consists of a textile surgical implant for parietal repair, the adhesive properties of which vary with the environment of the product.
- the implant is available, without these examples being limiting, in a hernia repair plate, in a patch for the plasty of the dura mater, in a gynecological implant impregnated with biocompatible adhesive.
- the biocompatible adhesive with which the implant is coated is inactive. Once in the body, the adhesive properties of the coating are activated when it is placed on the internal tissues by the surgeon. Indeed, the simultaneous action of the pressure force that the surgeon exerts on the implant combined with the humidity of the tissues activates the adhesive properties of the bioadhesive polymer composition coated on the textile or impregnated in the textile making up the implant.
- the bioadhesive polymer composition used is a water-soluble polymer composition having an ability to adhere the implant, in a repositionable manner, to the tissues of the human body only under the combined action of a pressure force and water molecules.
- This bio-adhesive is advantageously a pressure-sensitive adhesive or PSA (Pressure Sensitive Adhesive) adhesive.
- PSA Pressure Sensitive Adhesive
- the bio-adhesive used comprises polyvinylpyrrolidone (PVP), a polymer having these particular adhesive properties.
- the adhesive properties of such adhesives have a persistent and effective action while allowing the repositioning of the implant by gripping the latter by the surgeon.
- the adhesive properties can optionally be adjusted by adding a selected proportion of polyethylene glycol (PEG).
- PEG polyethylene glycol
- polyvinylpyrrolidone with or without the presence of polyethylene glycol which is one of the pressure-sensitive adhesives can also be used.
- the ideal proportion allowing to obtain the most adherent mixture is 64 percent of PVP for 36 percent of PEG (mass proportions), at a relative humidity level of 50 to 65%.
- the viscosity of the mixture can be controlled by the amount of water added: the PVP is polar and very soluble in water. Beyond 36%, the more the PEG is increased in proportion, the more the grip is limited. However, to decrease the cost of a bioadhesive polymer composition comprising PVP and avoiding too great a rigidity thereof, the quantity of PEG must not be too low.
- the viscosity tests measured by shear stress on a Mettler viscometer, indicate that the aqueous solution of PVP and PEG is shear thinning and has a thixotropic nature.
- the ideally obtained solution is sufficiently fluid to be applied, but also sufficiently viscous not to fuse, because its viscosity remains constant.
- Bonding of the implant comprising the aforementioned adhesives is created by the appearance of Van Der Walls type chemical bonds or by hydrogen bonds, and not by covalent bonds.
- the covalent bonds are strong and do not allow easy repositioning of the implant by the surgeon, if he so wishes, while the weak bonds generated by these adhesives are sufficient for the fixed retention of the implant on tissues under stress. , while allowing repositioning of the implant.
- the impregnation of textile surgical implants in an aqueous solution of bioadhesive polymer or polymers thus described is carried out in a clean room.
- the textile structure of the implant is, for example, made of polypropylene or polyester, knitted, woven or non-woven.
- the invention avoids the surgeon or his assistants the delicate operative phase of coating and metering of adhesive on the implant, in the operating room, just before installation, since the polymeric composition is already impregnated on the implant, at the not active in an ambient environment.
- the implant is already ready to be inserted and glued into the patient's body and will develop its advantageous properties when it is placed on the tissue.
- the invention has the advantage of being an atraumatic bio-adhesive implant for rapid fixing and easily repositionable at the time of placement by the surgeon.
- the bioadhesive is composed of polyvinylpyrrolidone.
- the polyvinylpyrrolidone which makes up the bio-adhesive, prevents necrosis or burning of the tissues.
- the degradation of the bio-adhesive agent gives way to fibrosis in a few weeks.
- the surgical implant comprises a biocompatible textile and at least one biocompatible polymeric composition which is water-soluble and having an ability to adhere the implant to the tissues of the human body, only under the combined action of a pressure force and of water molecules, repositionably.
- the polymer composition very advantageously comprises a polymer adhesive from the family of pressure-sensitive adhesives.
- the biocompatible polymeric composition is impregnated on at least part of the implant or coated on at least one of the surfaces of the implant.
- the self-adhesive biocompatible polymeric composition can be mixed with active pharmaceutical agents (antibiotics, anticancer agents, autocoagulant for example).
- the polymeric composition may comprise polyvinylpyrrolidone (PVP), and may alternatively comprise a mixture of polyvinylpyrrolidone (PVP) and polyethylene glycol (PEG) which can advantageously replace the PVP used alone.
- the polymeric composition may include carboxymethylcellulose (CMC). It is possible to use, as polymeric composition, a mixture of polymers consisting of carboxymethylcellulose (CMC) and polyethylene glycol (PEG).
- the self-adhesive biocompatible polymeric composition can also comprise a copolymer composed of monomers belonging to the family of acrylates and of monomers selected to confer water-solubility on the self-adhesive biocompatible polymer.
- the acrylate monomer can be chosen from the class comprising Octyl acrylate, 2-Ethylhexyl acrylate, Isooctyl acrylate, Isononyl acrylate, 1 Hexyl acrylate, Butyl acrylate, and the monomer selected to confer solubility in water with the self-adhesive polymer composition is chosen from the class comprising ⁇ -acryloyloxypropionic acid, acrylic acid, vinylphosphonic acid, 1 methacrylic acid.
- the self-adhesive biocompatible polymeric composition can also comprise a copolymer composed of monomers belonging to the class of acrylates, of monomers selected to confer water solubility of the self-adhesive polymer, as well as monomers of Hydroxyalkyl (meth). acrylates.
- the acrylate monomer can be chosen from the class comprising: Octyl acrylate, 2-Ethylhexyl acrylate, Isooctyl acrylate, Isonylyl acrylate, Hexyl acrylate, Butyl acrylate; the monomer selected to confer solubility in water to the self-adhesive polymeric composition can be chosen from the group comprising: ⁇ -acryloyloxypropionic acid, acrylic acid, vinylphosphonic acid, methacrylic acid; the hydroxyalkyl (meth) acrylates monomer can be selected from the group comprising: 2-hydroxyethyl acrylate, 2-hydroxypropyl acrylate, 2-hydroxyethyl methacrylate, 2-hydroxypropyl methacrylate.
- the first possible is to carry out the invention by the technique of impregnation: the biocompatible polymer composition is impregnated at the heart of the textile surgical implant, by soaking the structure in an aqueous solution in at least one biocompatible polymer, for a few seconds. The implant is then suspended in an oven for at least 24 hours, at a temperature of 50 ° Celsius.
- the invention is carried out by coating an aqueous solution of at least one polymer.
- the aqueous solution of at least one polymer contains per 100 grams of demineralized water 165 grams of PVP of grade K30 (molecular mass between 44 and 58 kilograms per mole) and 19 grams of PEG by mass molecular 400 grams per mole.
- the drying of the implant thus obtained is done flat, in an oven at 50 ° Celsius, for at least 24 hours.
- a film of at least one polymer deposited on the surface of the fibers of the implant is obtained.
