1. A device for treating an aneurysm by means of coagulation within a tissue pocket of said aneurysm, comprising:
- an introducer having alumen therein, with a needle being removably disposed in said lumen;
a filament which is adapted to be introduced into the pocket of said aneurysm, where said filament will temporarily dwell, and to roll up on itself therein; and
a filament delivery device, adapted for insertion in said lumen in place of said needle to introduce said filament into the pocket through the introducer.

36. A method for treating aneurysms comprising the following steps:
-
introducing in a pocket of an aneurysm an introducer having a removable needles;
removing the needle;
inserting a filament delivery device in the introducer;
introducing a thrombogenic bendable filament through the introducer into the pocket;
causing the filament to form a ball inside the pocket;
allowing the filament to provoke coagulation of the blood contained in the pocket; and
removing the filament. - View Dependent Claims (37, 38)
the filament removing step removes the filament through the introducer and filament delivery device; and
the method further comprises the steps of;
removing the filament delivery device; and
removing the introducer.

42. A device for treating an aneurysm by means of coagulation within a tissue pocket of said aneurysm, comprising:
-
an introducer comprising a removable needle;
a filament which is adapted to be introduced into the pocket of said aneurysm, where said filament will temporarily dwell, and to roll up on itself therein; and
a filament delivery device, adapted to introduce said filament into the pocket through the introducer, and to retain at least a proximal end of the filament such that said filament delivery device can withdraw said filament from the pocket after a defined time, the filament delivery device comprising an envelope which can be torn longitudinally and in which the filament is accommodated.
