Device for the Implantation of Self-Expanding Endoprostheses

Abstract

Abstract A device for implanting endoprostheses (1) has basically a tubular outer body (2) and an elongated core element (3) placed inside of this. To operate the device, both the core element (3) and the tubular body (2) are provided with handles (5, 6) at their proximal ends. In order to produce a form-locking connection between the endoprosthesis (1) and the core element (3), the core element (3) exhibits a region (10) in which is impressed a relief corresponding to the inner form of the endoprosthesis (1). As a result of this, there are a great number of form- locking meshing sites between the enclosed, folded endoprosthesis (1) and the core element (3). A device with this type of design permits partially released endoprostheses (1) to be folded back up again by pushing the tubular body (2) forward so that the endoprosthesis (1) may be repositioned. In addition, sure and reliable operation is achieved by this type of stamping of the core element (3).
