Abstract
The present disclosure relates to a braid for treating an aneurysm. The braid can include a proximal expandable portion for positioning inside the aneurysm and sealing across a neck of the aneurysm. The braid can also include a distal expandable portion distal of the proximal expandable portion, the distal expandable portion for filling the aneurysm.
Claims19
A braid for occluding an aneurysm, the braid comprising:
- a proximal expandable portion capable of moving from a collapsed state within a microcatheter to a deployed state within the aneurysm, wherein in the deployed state, the proximal expandable portion forms a proximal sack sealing about a neck of the aneurysm;
- a junction disposed at a distal end of the proximal expandable portion;
- and
- a distal expandable portion connected to the junction and distal end of the proximal expandable portion, wherein the distal expandable portion is capable of moving from a collapsed state within the microcatheter to a deployed state whereby the distal end expandable portion forms a distal sack at least partially filling the aneurysm;
- wherein the distal expandable portion is capable of applying an outward force on the proximal expandable portion to anchor it in the aneurysm, and wherein during delivery, the proximal expandable portion contacts the distal expandable portion causing a resistive force facilitating inversion of the proximal expandable portion.

A system for treating an aneurysm, the system comprising:
- a microcatheter;
- a delivery tube translatably disposed in the microcatheter;
- and
- a braid detachably connected to the delivery tube and slideably disposed within the microcatheter in a collapsed state and distally translatable from within the microcatheter to a deployed state, the braid comprising:
- a proximal expandable portion capable of moving from the collapsed state within the microcatheter to the deployed state within the aneurysm, wherein in the deployed state, the proximal expandable portion forms a proximal sack sealing about a neck of the aneurysm;
- a junction disposed at a distal end of the proximal expandable portion;
- and
- a distal expandable portion connected to the junction and distal end of the proximal expandable portion, wherein the distal expandable portion is capable of moving from a collapsed state within the microcatheter to a deployed state whereby the distal expandable portion forms a distal sack at least partially filling the aneurysm, the distal expandable portion comprising a single layer mesh with an open distal end;
- wherein the braid expands to the deployed state as a distal end of the braid distally exits the microcatheter.

A method of delivering an occlusive device to an aneurysm, the method comprising:
- selectively positioning a braid in a vessel associated with the aneurysm, the braid comprising:
- a proximal expandable portion capable of moving from a collapsed state within a microcatheter to a deployed state within the aneurysm;
- a junction disposed at a distal end of the proximal expandable portion;
- and
- a distal expandable portion connected to the junction and distal end of the proximal expandable portion, the distal expandable portion capable of moving from the collapsed state within the microcatheter to the deployed state at least partially filling the aneurysm;
- distally sliding the braid, by a delivery tube, from the microcatheter towards the aneurysm thereby
- at least partially filling the aneurysm by expanding the distal expandable portion inside the aneurysm to form a distal sack;
- anchoring the braid to the aneurysm by expanding the proximal expandable portion to form a proximal sack sealing about a neck of the aneurysm;
- and
- proximally translating the distal sack causing the proximal sack to invert into itself.
