1. A method for testing insurgence of spinal ischemia due to endovascular treatment of aortic aneurisms comprising:
- providing an implantable and removable medical device for the endovascular insertion in the thoracic aorta, said medical device comprising a supporting structure which has a substantially tubular shape and is covered externally by a covering, to define a duct for blood circulation, said device comprising extraction means for extracting said duct from the body of the subject in whom it is inserted, said extraction means being associated with said duct and communicating with the outside of said body;
introducing a device in a thoracic aorta of a patient, in a segment of the thoracic aorta where an aneurism is formed, the device comprising;
a supporting structure having a substantially tubular shape;
a covering coupled externally to the supporting structure; and
means for extracting the device, the extracting means communicating with an outside of the patient;
defining a duct for blood circulation with the device;
expanding the duct to make a wall of the segment radially impervious to blood, thereby reducing blood flow through the intercostal arteries;
evaluating the patient response to reduction of blood flow through the intercostal arteries; and
selecting an aneurism treatment method based at least in part on the evaluation.

Abstract
A removable implantable medical device (1) for the endovascular treatment of aneurysm, particularly of aneurysm of the thoracic aorta, comprising a supporting structure (2) tubular in shape and covered externally by a covering (3).
The supporting structure (2) and the covering (3) define a duct (4) for blood circulation.
The device is provided with extraction means (5) for extracting the duct (4) from the body of the subject in whom it is inserted. The extraction means (5) are associated with the duct (4) and communicate with the outside of the body.
