Definitions
- the present invention relates to a transcutaneous implanted fluid transfer device, allowing the circulation of a fluid, biological or not, between an organism and an external device.
- the transcutaneous passage of liquids is carried out by means of a catheter temporarily crossing the cutaneous plane through an incision, and possibly having means of temporary fixation on the skin, using adhesives or dressings. This is how liquids can be introduced into or extracted from the body, for example for extra ⁇ bodily circulation, dialysis, administration of infusion fluids or even the extraction of effusions using 'a redon.
- Implantable devices are already known which make it possible to ensure an electrical connection between conductors implanted in the body and external conductors capable of being connected to a source of energy or to an apparatus. In reality, these projects have never passed the experimental stage, in particular because of the risk of rejection as well as the mechanical instability incompatible with the practice of everyday life.
- implants are already known in the form of a plate, intended to be fixed to a bone surface, in particular the temporal or parietal bone, and having a transcutaneous stud comprising, at its external end, fixing means making it possible to receive a prosthesis for aesthetic purposes.
- Such implants made in particular of titanium, are well tolerated, with very reduced risks of infection.
- the present invention proposes to provide a transcutaneous fluid transfer device which can be implanted permanently, and even permanently, to ensure the transfer of a fluid between external means and implanted means, under conditions of strict asepsis and which can be fixed in bodily locations in which it is apparently not possible to implant and implement fluid conduits.
- the invention also aims to achieve such devices in economical conditions with a limited number of parts and easy assembly.
- the subject of the invention is a transcutaneous device for transparent transfer of fluid between an organism and an external device, characterized in that it comprises a substantially flat base, made of a material tolerable by the organism and capable of extending parallel to the skin, in a subcutaneous position, the height of which is sufficiently low to allow easy healing of the cutaneous plane over the base, said base comprising means allowing its attachment to an underlying organic support, for example a bone surface , a transcutaneous abutment capable of being tightly fixed on said base and through the skin through an incision to present an end external to the body, at least one fluid passage extending in the pillar, and having an external mouth opening onto the external surface of the pillar, a valve arranged in the passage, preferably on the outside of the pillar, to maintain a normally closed position preventing the exit of a fluid, possibly present, and the entry of materials or microorgan
- the base has an internal passage extending substantially in its plane, that is to say perpendicular to said pillar, and opening into a nozzle in or on which said implantable conduit can be fixed, and communicating, at its other end, with the substantially perpendicular passage contained in the pillar.
- the implanted conduit or conduits remain constantly parallel to the skin plane in all their parts close to the base without having any elbow oriented transversely to the skin.
- the pillar can be fixed, in a removable manner, on the base with the interposition of a seal, thanks to fixing means capable of extending in the pillar to join the base.
- the base and the implantable conduit (s) being fixed, in a subcutaneous position, on the underlying organic support, the surface of the base intended to receive the pillar being temporarily covered by a protective cap, which allows the skin to heal, after which an incision is made at the part of the base intended to receive the pillar and, after removal of the protective cap, the pillar is fixed to the base through the incision.
- the seal between the base and the pillar can be ensured by any suitable means, for example one or more O-rings or annular seals or even a continuous membrane capable of being perforated at the level of the passage or passages contained in the pillar.
- the means for fixing the removable pillar to the base preferably include one or more screws capable of passing through the pillar in order to be screwed into a complementary tapping on the base.
- this screw is hollow, so as to form a fluid passage and be able to communicate with a passage contained in the base, the screw having, at its upper end, the above-mentioned valve.
- the base can advantageously be in the form of a plate, of the osteosynthesis plate type, with holes allowing the passage of screws, clips, or other fixing means against a bone surface previously deperosted, said plate having a shaped part.
- base, the surface of which faces the pillar has at least one opening communicating with said implantable conduit, preferably by through a passage made along the plate in a thickened element of the plate, allowing both to connect the conduit substantially in the plane of the plate, that is to say in a plane substantially parallel to the skin surface.
- the implantable conduit can be brought to the level of the part of the plate intended to form the base itself, subject to providing in this part a connection means allowing connection with said conduit implantable in a position substantially parallel to the plate, that is to say substantially perpenicular to the abutment.
- the base may have no passage of fluid and the implanted conduit is then brought, parallel to the base, to connect directly to a radial mouth of the lower end of the abutment, provided that the internal end of the abutment enters the base to approach the bone surface on which the base is fixed.
- the device according to the invention is preferably made of a metallic material and, in a particularly preferred manner of titanium or titanium alloy. It is particularly well suited to be fixed on a cranial bone, preferably parietal or temporal in the vicinity of the ear.
- the device according to the invention may also include means allowing transcurrent passage of electrical conductors and / or optical fibers.
- An electric current transfer device is described, for example, in PCT / FR / 96 00141.
- Such an electric current transfer device can be contained, either in the same pillar which presents the fluid transfer duct (s), or, less preferably, in a separate pillar carried, preferably, by the same base at a certain distance from the pillar for the passage of fluid.
- the device according to the invention can be used to ensure the transfer of any fluid to or from the body.
- any fluid such as insulin, morphine derivatives, anticoagulants, chemotherapy products, etc.
- medicament such as insulin, morphine derivatives, anticoagulants, chemotherapy products, etc.
