Aneurysm liner
First Claim
1. A device for treating an aneurysm in a parent vessel, the parent vessel defining a lumen, the aneurysm having a neck and an inner wall defining a cavity communicating with the lumen, the device configured for deployment within the cavity, and comprising:
- an expandable aneurysm liner having an axial length; and
an extender member having an axial length substantially no greater than the axial length of the expandable liner and being located inside the aneurysm liner wherein the liner and extender member are movable between an insertion position and a deployed position, the liner being in a relatively low profile conformation and the extender member extending longitudinally and having an overall longitudinally elongate conformation when the liner and the extender member are in the insertion position.

Abstract
An improved aneurysm liner is used for treating an aneurysm in a parent vessel. The parent vessel defines a lumen. The aneurysm includes a neck and an inner wall defining a cavity in fluid communication with the lumen. The liner device is configured for deployment within the cavity. The device includes an extender inside an expandable aneurysm liner. The proximal pusher end of the extender receives force from a distal end of a delivery catheter for maneuvering the device into a deployment position. The device is arranged such that, when deployed within the cavity, the liner is expanded to fill the cavity. In treating an aneurysm, the liner device is directed to the aneurysm site by a guidewire that extends through the extender. Upon removal of the guidewire, the extender is released within the liner and the liner is expanded to fill the cavity.

19. A method of treating an aneurysm in a parent vessel having a lumen, the aneurysm having a neck and an inner wall defining a cavity communicating with the lumen, the method comprising:
-
providing a liner having an axial length and an extender member therein and connected thereto, the liner and extender member being movable between a low profile insertion position and an expanded deployed position, the extender member having an axial length substantially no greater than the axial length of the liner, the extender member defining a guidewire receiving passage receiving a guidewire and assuming a longitudinally elongate conformation when in the insertion position;
endovascularly moving the liner and extender member over the guidewire to a site proximate the aneurysm; and
deploying the liner within the cavity. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
providing a catheter coaxially aligned with, and disconnectably coupled to, a proximal mouth of the liner.
-
-
21. The method of claim 20 wherein endovascularly moving comprises:
-
maintaining the liner in a relatively low profile insertion position; and
advancing the extender member and catheter over the guidewire and into the aneurysm.
-
-
22. The method of claim 21 wherein deploying the liner comprises:
-
removing the guidewire from the guidewire receiving passage in the extender member; and
expanding the liner.
-
-
23. The method of claim 22 wherein the step of expanding the liner includes releasing the extender member into a preformed, radially expanded shape.
-
24. The method of claim 22 wherein the step of expanding the liner includes filling the liner with an embolic agent.
-
25. The method of claim 22 wherein deploying further comprises:
detaching the catheter from the aneurysm liner.
-
26. The method of claim 22 wherein removing the guidewire comprises advancing the liner and extender member distally beyond the guidewire.
-
27. The method of claim 26 wherein the embolic agent is one of a detachable coil, a liquid polymer, occlusion particles or a combination thereof.
-
28. A system for treating an aneurysm in a vessel, the aneurysm having an inner wall and a neck defining a cavity, the system comprising:
-
a catheter having a distal end; and
a treatment device disconnectably attached to the catheter;
wherein the treatment device comprises an expandable liner having an axial length, and an extender coil, the liner and extender coil being movable between a low profile insertion position and a radially expanded deployed position, the extender coil having an overall longitudinally elongate conformation when in the insertion position, the extender coil including a distal end attached to the expandable liner and a proximal end coaxially alignable with the distal end of the catheter, the extender coil defining a guidewire lumen, the extender coil having an axial length no greater than the axial length of the liner.
