<p>The invention concerned, stent for catching and breaking up thromboemboli, consists of a plastic tube (3) into which nitinol meshes are diagonally placed (7) and (9) connected with tablet (6), i.e. (8), made of crystal or ceramics. Two microchips (5) are built into a plastic pipe (5) during the manufacturing process - the one (5) which is connected to the tablets (6) and (8) via current carrying wire and to the other microchip (4) which is, via current carrying wire, connected to the crystal or ceramic tablet (5), which covers a part of space for medication (2). The microchip (5) is programmed in such way that it forwards a micro deformation of the net (7) i.e. electrical impulse from the tablet (6) to the microchip (4) only when it detects the micro deformation of the net (7) hit by a thromboembolus, but does not forward if at the same time a micro deformation is detected on the net (9), while the microchip (4), which forwards an electrical impulse to the plate (1), is programmed for counting the number of thromboemboli hits and, based on an external cause, it sends the impulse to the external source of cause (the reader, which can be placed on a wristband) informing on the amount of medication remaining. The plastic flex (10) is, after inserting and positioning of the stent, extracted from the blood vessel.</p> |
