摘要:
The invention relates to a device for introducing an implant (1) into blood vessels or hollow organs of the human or animal body, comprising an implant (1), an insertion wire (14), and a transfer tube (13), wherein the implant (1) can be deformed in such a way that, in a micro-catheter (8), the implant assumes a form having a reduced diameter and, at the implantation location, following the removal of the external force by the micro-catheter (8), expands whilst adapting to the diameter of the blood vessel or hollow organ. A a holding element (2) is arranged on the insertion wire (14) and the holding element (2) has peripherally at least one, preferably multiple, grooves (3) let into the holding element (2), which extend on the circumference of the holding element (2) and form tracks in the form of curved lines. The implant (1) has at the proximal end at least one, preferably multiple, holding wires (5) extending in the proximal direction and fitted into the grooves (3), wherein the transfer tube (13) is pulled with a form fit over the holding element (2) and the holding wires (5) fitted into the grooves (3, such that the holding wires (5) are held in the grooves (3) by a frictional fit and the implant (1) is released by pulling back the transfer tube (13) in the proximal direction. According to an alternative embodiment, the invention relates to a device for introducing an implant (1) in which the transfer tube (13) projects into the proximal end of the implant (1), wherein there is an elastic contact surface between the inner side of the implant (1) and the outer side of the transfer tube (13), such that a frictional connection is made between implant (1) and transfer tube (13), which permits longitudinal distal or proximal displaceability of the implant (1) within the micro-catheter (8) as a result of longitudinal movement of the transfer tube (13).
