Abstract: A method of producing glass tiles, glass borders, ornamental panels made from glass or the like, the rear side of which is structured to form a relief, involves the following steps: trimming the glass slab to the desired size, applying an adhesive layer on predetermined regions forming a pattern or a motif on the rear side of the glass slab by means of a printing technique, depositing a powder coating that resists high temperatures on the rear side of the glass slab and removing the excess powder from the non-adhesive regions of the glass slab, positioning the glass slab with its coated rear side on a base that resists high temperatures and is provided with a parting agent, submitting the glass slab to a temperature treatment until plastic deformation is achieved, the glass slab sinking into the pattern or motif formed by the powder coating on account of its own weight, and removing the powder that resists high temperatures from the regions covered with the pattern or the motif once the glass slab has c

Abstract: For the better anchoring of a stent in its use area within a vessel, in the case of a stent expandable from a radially contracted introduction state into a radially expanded position state and having a body with material areas in the form of ribs and gaps in the form of free spaces between the ribs, in the radially expanded state at least one front end of the stent has a greater radial extension than the remaining main stent body with the material areas of the body being relatively thin and without material crossing points as in knitted and braided structures.

Abstract: A stent for reducing a diameter of a duct in a body of a living creature. The stent includes a sleevelike port having walls provided with perforations enlarged ends as well as a intermediate area reduced in diameter by a constriction. Thrombogenic threads are provided on an exterior of the sleevelike port between the enlarged ends.

Abstract: A stent, which has an easier and better bendability and higher flexibility than known stents, has several meander paths (2,2a,2b,2c) successively arranged in the axial direction (A) and extending over its circumference (U), and between axially facing areas (3,3a,3'a,3b), interconnected by connecting areas (4,4a,4b,4c), of the meander paths (2,2a,2b,2c) in the circumferential direction (U) there are at least two facing, non-interconnected areas (3,3a,3'a,3b) of each meander path (2,2a,2b,2c)

Abstract: For the better anchoring of a stent in its use area within a vessel, in the case of a stent expandable from a radially contracted introduction state into a radially expanded position state, in the radially expanded state at least one front end of the stent has a greater diameter than the remaining main stent body with ribs of the front end being longer than those in the main stent body.

Abstract: An apparatus for widening a stenosis in a body cavity, such as an artery, in the bile duct, in the ureter, etc. is proposed, which in view of a problem-free, reliable and permanent widening of a stenosis is characterized by a memory alloy part having a cylindrical jacket-shaped outer contour, said part radially widening at a transition temperature, which is above ambient temperature, but below body temperature, while maintaining a cylindrical outer contour and at a temperature below the transition temperature the diameter is smaller than that of the vessel.

Abstract: An apparatus for correcting a positioning of a stent for widening or keeping open a stenosis, in blood vessels, the urethra, the ureter, etc. The apparatus includes a guide part slidably housing an elongated wire part provided at a forward end thereof with radially expandable wire portions having structures for grasping the stent.

Abstract: A stent set for keeping a urethral stenoses open, particularly in the vesical neck, for bladder drainage with an intraurethral catheter having a largely cylindrical basic body, with small baskets or cages at respective ends of the basic end an intraurethral insertion rail and a slide. At a rounded tip with at least one initial opening is provided at a proximal end of the intraurethral catheter.

Abstract: Guide wires for the medical field and which are e.g. used for the introduction of catheters, locks, etc. into the human body and in particular into vessels and organs are disclosed. To avoid the risk of a detachment of parts, the guide wire is provided as a one-piece, highly flexible material guide wire, which has a proximal end portion with a first thickness and following onto the same at least one cross-sectional reduction for increasing the bending flexibility at least in an area connected to the proximal end portion and which in the distal end portion remote from the proximal end portion has portions with a cross-section of the same order of magnitude as that of the proximal end portion. According to a preferred process for producing such a guide wire, a rod-shaped part with a smooth outer wall is drawn continuously and at least once over part of its length from an etching bath attacking its material into a non-etching environment.

Abstract: The invention relates to an apparatus for widening a stenosis in an elongated body cavity such as an artery, the urethra, the ureter, a bile duct or the like, characterized by an endoprosthesis made from a memory alloy with a substantially cylindrical jacket-like outer contour with a lock surrounding and radially holding together the endoprosthesis and with an applicator for the endoprosthesis. It is important that the apparatus is supplied in such a way that in the delivery pack the endoprosthesis is held radially from the outside in its compressed (low temperature) position, which is ensured by the above-described construction of the apparatus according to the invention.
