  • Patent number: 11857405
    Abstract: Medical Implant (100), comprising a microbial cellulose tube (1), comprising a wall (2) having an inner surface (3) and an outer surface (4), wherein the wall comprises several layers (5, 6, 7) of microbial cellulose, wherein said layers are concentric or substantially concentric to a longitudinal axis (L) of the tube, a stent (9) which placed inside of the microbial cellulose tube (1), wherein an outer surface (10) of the stent contacts the inner surface (3) of the microbial cellulose tube (1), and method for producing such implant. The implant can be covered with newly created bile duct epithelium, thereby creating a new bile duct from body cells. The implant can be removed after completion of creation of the new bile duct. So, the implant as suitable as a temporary implant. The implant can be used for surgery, such as surgery of gall bladder, bile duct and/or liver, e.g. gall bladder removal, hepatobiliary malignancy surgery or liver transplantation.

  • Publication number: 20190062477
    Abstract: The present invention relates to a curable composition which can be cured by radiation and/or the influence of temperature; a cured product which is obtained from such a composition; an object and a composite which have the cured composition; and a method for producing the same. The cured composition has a high refractive index.

  • Patent number: 6932842
    Abstract: An implant is generated which is functionally and aesthetically adapted to the patient with a greater degree of precision, irrespective of the size, form and complexity of the defect, whereby the implant can be produced and operatively inserted into the patient over a short time period and in a simple manner. A virtual three-dimensional model of the patient which is formed from existing recorded (two-dimensional) image data of the patient is compared with real medical reference data. The comparison which is, for example, carried out using a data bank with test person data enables a reference model object which is most suited to the patient or closest to the patient model to be selected or formed and a virtual implant model is generated accordingly. Computer numeric control data is directly generated from the implant model which is generated virtually in the computer for program-assisted production of the implant.
