FIELD: medicine.
SUBSTANCE: implant comprises an attachment to a human or animal living biological tissue. The implant has an external surface containing the first part and the second part which have different properties in relation to biocompatibility of each part with a biological tissue. The implant contains at least one surface patch containing a base surface forming said first part, and one or more limited areas forming said second part, and said one or more limited areas consist of a set of the limited zones more than five in number. The method for making said implant starts with equipping the implant with a perforated covering device, and applying said one or more limited areas outside of the covering device in the form of deposited layer so that notches in the covering device limit said second part of the surface. The method for making said implant starts with coating the implant and equipping it with the perforated covering device, and removing said coating from the notch zones of the covering device to provide said one or more limited areas. The covering device is designed to be used in the methods described above. An element of the implant contains comprises an attachment to a human or animal living biological tissue, herewith the implant has the external surface containing at least one surface area with a topographically modified surface. The attachment is supplied with at least one thread; the surface area is located in a profile valley of said at least one thread, and relief processed by making a number of recesses. Said recesses follow each other along the longitudinal length of the profile valley of said at least one thread. The method for making said element of the implant consists that laser generates said surface topography.
EFFECT: invention enables the implant to be adapted to interact with the biological tissue so making the implant with the surface possessing bioactive properties which thus interacts with the surrounding tissue and is simultaneously characterised by the sufficiently documented long-term actions.
