Abstract
The invention is also directed to a device for treating an aneurysm which has a cover covering the neck of the aneurysm and a lateral portion extending into the aneurysm. The invention is also directed to a cover which is used to cover the neck of the aneurysm thereby isolating the aneurysm from the parental vessel.
Claims30
A method of treating an aneurysm, comprising the steps of:
- providing a device having a cover and a lateral extension, the cover and extension being movable from a collapsed position to an expanded position;
- advancing the device through a patient's vascular system to an aneurysm with the cover in the collapsed position;
- moving the lateral extension into the neck of the aneurysm and the cover over the neck of the aneurysm to isolate the aneurysm from the parental vessel;
- coupling at least the lateral extension to a source of energy;
- and
- delivering the energy to the lateral extension after the advancing step.
3 more elements
A method of treating an aneurysm, comprising the steps of:
- providing a cover which is positioned around an expandable element in a collapsed position, the cover being covered by a sheath, the cover also having an extension which is movable between a retracted position and an expanded position, the extension extending away from the cover in the expanded position;
- advancing the cover to an aneurysm in a patient with the cover in the collapsed position;
- withdrawing the sheath to expose the cover;
- expanding the expandable member thereby expanding the cover, the cover expanding to an expanded condition, the cover being positioned over a neck of the aneurysm while the extension is in the expanded position and passes into the neck of the aneurysm.
1 more element
A method of treating an aneurysm, comprising the steps of:
- providing a device having a cover and a lateral extension, the cover and extension being movable, from a collapsed position to an expanded position, the cover being wrapped around the expandable element;
- advancing the device through a patient's vascular system to an aneurysm with the cover in the collapsed position;
- moving the lateral extension into the neck of the aneurysm and the cover over the neck of the aneurysm to isolate the aneurysm from the parental vessel.
