Definitions

  • the present invention relates to an occlusion device consisting of a braid of thin wires which is given a suitable final shape by means of a reshaping and heat treatment process and which can be tapered to implant or explant to the diameter of a catheter used for intravascular surgery, with a proximal retention area , a distal retention area, in which the ends of the wires or threads converge in a socket, and with a cylindrical web between the proximal retention area and the distal retention area, the two retention areas after implantation on both sides of a shunt to be closed in a septum Come as the web runs through the shunt.
  • the invention further relates to a surgical set for implanting and explanting an implant, in particular an occlusion device described above.
  • the present invention relates to a method for the repeatable coupling of an implant, in particular an occlusion instrument described above, to such surgical equipment.
  • Such a system could, for example, consist of two umbrellas, each positioned on the distal side (ie on the side further away from the center or the heart) or on the proximal side (ie on the side closer to the center) of the septum are then screwed into a double umbrella in the septal defect.
  • the closure system In the assembled state, the closure system then usually consists of two open umbrellas, which are connected to one another via a short pin running through the defect.
  • the implantation procedure is relatively complicated, difficult and complex. Apart from the complicated implantation of the closure system in the septum defect to be closed, there is basically a risk of material fatigue with industry fracture in the umbrellas used. Furthermore, thromboembolic complications are often to be expected.
  • the end of the distal retention area has a socket which can be brought into engagement with the introducer or guide wire. It is provided that the intervention in the defect can be easily released after the positioning of the occlusion device.
  • the coupling to the insertion wire is designed as a screw thread. The occluder can be pushed forwards or backwards in the catheter tube using the insertion wire. After placement in the cardiac septum, the insertion wire is unscrewed and the occluder is finally released. A correction is then no longer possible.
  • the occluder Since the insertion wire and the coupling are relatively stiff and the catheter hits the cardiac septum at a shallow angle for anatomical reasons during the minimally invasive implantation of the occluder over the leg artery, the occluder is held in a tilted position when it is deployed and the umbrellas cannot be on both sides of the shunt. In this situation, the surgeon cannot recognize whether the occluder will assume its predetermined fit when disconnected. This results in a great deal of uncertainty for the surgeon, in particular because the uncoupled occluder cannot be repositioned minimally invasively.
  • the sleeve protruding from the proximal retention area of the occluder can cause the problem that the implant used causes embolism-related problems, especially consecutive embolization it also prevents complete endothelialization of the occlusion implant.
  • the present invention is based on the object of specifying an occlusion instrument which, in the inserted state, is as flat as possible on the proximal side of the septal defect and can be retrieved after uncoupling if a defect is visible.
