摘要:
An implant system comprising a functional implant (5, 6) that fulfills a medical function, particularly a bone implant, which is formed at least in part of a metal material that can be degraded by the body (2) of the implant wearer, as well as a control device (7) for controlling the degradation behavior of the functional implant (5, 6). The control device (7) has a counter-electrode (10) to the functional implant (5, 6), and a voltage source (8) for making available a polarization voltage (ΔU) between functional implant (5, 6, 15) and counter-electrode (10), to control the degradation behavior of the functional implant (5, 6).
摘要:
An implant for implantation in a human or animal body having a structure comprising a) an implant base body; b) a primer layer which is partially or completely applied to the surface of the implant; c) an active ingredient layer consisting of one, two, three or more active ingredients applied entirely or partially to the surface of the primer layer; and d) a diffusion-controlling layer which is applied partially or entirely to the active ingredient layer, and optionally to the primer layer, wherein diffusion of the active ingredients of the active ingredient layer is controlled. Also disclosed is a manufacturing method for an implant.
摘要:
The present invention relates to an implant (10), and particularly to an intraluminal endoprosthesis, comprising a body and at least one abluminal layer (3) disposed on the body, the abluminal layer preferably containing at least one pharmaceutically active substance. In order to protect the abluminal layer (3) from delamination or shearing, the abluminal layer (3) is additionally fastened to the implant body at least in a transition region (7) by way of at least one anchoring layer (5) disposed on the abluminal layer (3). In addition, methods for producing such an implant are described.
摘要:
An implant is proposed, in particular made from a base material including a biodegradable metal and/or a biodegradable metal alloy, wherein the implant includes a coating made of crystalline calcium phosphate and/or amorphous calcium phosphate.
摘要:
A method for producing an agent depot for mechanical connection to a surface of an endovascular implantable body, comprising a) providing one or more polymers; b) providing one or more agents; and c) producing an agent depot from said polymers and said agents, the agent depot being mechanically connectable to the surface of the body using force action or adhesive.

摘要:
An implant comprising a body (1), at least one active pharmaceutical substance (4) and an element (5, 15, 35, 45, 55) deflectable in relation to the body, serving to release the at least one active pharmaceutical substance (4) during or after an external excitation of the deflection. Also disclosed is a system of such an implant and an excitation device (30, 70).
摘要:
An endoprosthesis, in particular an intraluminal endoprosthesis, for example a stent, having a base body composed at least partially of a metallic material, and having a functional element which is attached to the base body or imbedded therein and which contains material that is radiopaque and/or X-ray opaque and has a different material composition, at least in a portion of its volume, compared to the material of the base body. To avoid contact corrosion and undesired corrosion, the functional element is provided with a barrier layer which electrically insulates the radiopaque and/or X-ray opaque material from the base body.
摘要:
The invention relates to an implant having a base body made of a biocorrodible material. A surface of the implant has a coating at least in some regions, wherein the coating comprises a tissue adhesive.
摘要:
A drug-eluting stent, comprising a base body that is made of an implant material, the base body being partially or entirely covered on the abluminal side with an active ingredient-releasing coating that comprises or is made of a polymer and an active ingredient having an antiproliferative effect, characterized in that the stent's luminal surface and the abluminal surface carrying the active ingredient-releasing coating are covered by a biocorrodible protective layer in a form-fitting manner.
