A device ( 30 ) for treating aneurysms comprises a bag ( 31 ) removably attached to the distal end of a catheter ( 14 ), the bag being arranged to be inserted in an aneurysm ( 20 ) and being of flexible and stretchable material and being permeable to blood components. Once the bag is inserted, individual GD coils ( 18 ) are introduced therein. The bag is inserted by a shoulder ( 42 ) or a widened portion ( 50 ) of a guide wire ( 40 ) engaging a marker ring ( 46 ). The bag material may encourage clotting. In another embodiment the bag ( 131 ) is located around the end of the catheter ( 114 ) during insertion. When insertion is completed, electrolysable struts ( 32, 172 ) are removed to separate the bag from the catheter. |
