20150157504 | DRAINAGE DEVICE AND METHOD OF PRODUCING SAME - The invention relates to medical technology and is intended for use in ophthalmology in the surgical treatment of various types of glaucoma. According to a first aspect of the invention, the drainage device for use in the surgical treatment of glaucoma is formed from a bioresorbable material in the form of a hollow profile with a closed contour in cross section, ensuring the possibility of the scleral flap passing through the cavity of the device during the surgical treatment. As a result, the formation of adhesions under the scleral bed, along the scleral flap rib and also between the scleral flap and the conjunctiva is prevented, the ease and reliability of fixing the device on the scleral flap is increased, and adverse immune and inflammatory reactions are reduced. According to a second aspect, the described drainage device is produced by manufacturing a blank from polymer material on a rod in the form of a hollow profile of closed cross section and subsequently cutting at least one section out of the blank in order to produce at least one drainage device. According to a third aspect of the invention, in order to produce the drainage device, a blank in the form of a hollow profile of closed cross section is woven from threads, and at least one section is subsequently cut out of the blank in order to produce at least one drainage device. According to a fourth aspect of the invention, blanks in the form of strips are produced from a flat preliminary blank made of polymer material, wherein the drainage device is produced by connecting the ends of at least one blank. | 06-11-2015 |
