| 摘要 |
The invention relates to a device for endovascular treatment, particularly for removing concretions from body vessels, comprising a receiving element (1) and a distal element (2), which can be moved relative to each other from an open position into a closed position, wherein the receiving element (1) comprises a distal opening (14), which is arranged opposite the distal element (2) and in the open position is arranged at a distance from the distal element (2). It is characterized in that the distal opening (14) of the receiving element (1) can be closed by a proximal end (21a) of the distal element (2) such that both elements (1, 2) form a substantially closed hollow chamber in the closed position for receiving an object (42), particularly a concretion. The invention further relates to a device for endovascular treatment, which is characterized in that the distal element (2) is adjusted such that a radial diameter can be increased as a function of the axial force component acting on the object (42). |
