Abstract: A training device for a surgical procedure for endovascular treatment of an aneurysm, includes a container having a wall defining a confined chamber and an access opening in the wall. The access opening allows insertion into the container of a guidewire and/or of a guiding catheter for endovascular surgery. A tube connects to the container at the access opening, and a movable element includes a target and connected control member. The target is within the container and includes a cannulation seat receiving the guidewire/guiding catheter. The control member at least partially protrudes out of the container through a control opening of the container wall. The movable element is movably constrained, at the control opening, to the container wall to enable the target to adopt different positions and/or orientations within the container. A training method for a surgical procedure of endovascular treatment of aneurysms uses the training device.
