Coated endovascular intrasaccular occlusion device
An endovascular treatment mesh device for closing outpouchings by affixing at least one amorphous hydrogel layer expandable in vivo to any or all surfaces of an expandable body comprising at least one material adapted to close said outpouching in the body. The treatment mesh further includes a telescoping center-support bar disposed therein, the center-support bar having at least two telescoping elements that act as reinforcing extension elements to minimize the risk of collapse. Hydrogel is affixed to the surface of the telescoping elements to inhibit retraction. An embodiment wherein the treatment mesh device is a stent.
1. A treatment device, which comprises:
an expandable member configured to at least partially occupy an outpouching in an organ and defining an interior, and being deployable within the outpouching with a delivery member; and
a reinforcing extension member mounted with respect to the expandable member to at least partially support the expandable member when deployed in the outpouching, the reinforcement extension member comprising a telescopic support including at least two telescopic elements configured for relative movement to control a length of the telescopic support, the at least two telescoping elements entirely confined within the interior of the expandable member upon deployment within the outpouching and released by the delivery member.
2. The treatment device according to claim 1 wherein the expandable member comprises a mesh device.
3. The treatment device according to claim 2 including a hydrogel coating disposed on one of an inner surface and an outer surface of the mesh device.
4. The treatment device according to claim 3 wherein the hydrogel coating is configured to expand in vivo.
5. The treatment device according to claim 3 wherein the hydrogel coating is one of biodegradable and non-biodegradable.
6. The treatment device according to claim 3 wherein the hydrogel coating is impregnated with at least one pharmaceutical compound.
7. The treatment device according to claim 6 wherein the at least one pharmaceutical compound is configured for controlled release in the organ.
8. The treatment device according to claim 2 wherein the mesh device is configured to at least partially occupy a vascular aneurysm.
9. The treatment device according to claim 2 wherein the mesh device is configured for at least one of intravascular use, the genitourinary tract, the biliary tract and the gastrointestinal tract.
10. The treatment device according to claim 1 wherein the telescopic support is preset to a minimum height.
11. The treatment device according to claim 1 including a delivery member to deliver the expandable member relative to the outpouching in the organ, the reinforcement extension member free from connection to the delivery member.
12. A treatment device which comprises:
an expandable member configured to at least partially occupy an outpouching in an organ and defining an interior;
a reinforcing extension member mounted with respect to the expandable member to at least partially support the expandable member when deployed in the outpouching, the reinforcement extension member comprising a telescopic support including at least two telescopic elements configured for relative movement to control a length of the telescopic support, the at least two telescoping elements entirely confined within the interior of the expandable member; and
a hydrogel coating disposed on at least one of the at least two telescopic elements of the telescopic support.
13. A treatment device, which comprises:
an expandable member configured for insertion in a vascular organ with a delivery member, the expandable member configured to expand to an at least partially expanded condition in association within insertion in a target site within the vascular organ; and
a telescopic support at least partially disposed in the expandable member and independent of the delivery member, the telescopic support configured to maintain the expandable member in the at least partially expanded condition, the telescopic support including first and second elements configured for relative movement to selectively control a length of the telescopic support with the expandable member, the telescopic support entirely confined within the interior of the expandable member when the expandable member is inserted in the target site and released from the delivery member.
14. The treatment device according to claim 13 including a hydrogel applied to the expandable member, the hydrogel expandable in vivo to assist in retention of the expandable member at the target site.
15. The treatment device according to claim 14 wherein the hydrogel coating is impregnated with at least one pharmaceutical compound.
16. The treatment device according to claim 13 wherein the expandable member is configured to at least partially occupy an aneurysm within the vascular organ.
17. The treatment device according to claim 13 wherein the expandable member comprises a stent configured for insertion at the target site within the vascular organ.
18. A treatment device, which comprises:
an expandable member configured for insertion in a vascular organ with a delivery member, the expandable member configured to expand to an at least partially expanded condition in association within insertion in a target site within the vascular organ; and
an extendable support at least partially disposed in the expandable member and independent of the delivery member, the extendable support configured to maintain the expandable member in the at least partially expanded condition, the first and second members of the extendable support entirely confined within an interior of the expandable member when the expandable member is inserted in the target site and released from the delivery member.
19. The treatment device according to claim 18 wherein the extendable support includes first and second members coupled to each other and configured for relative movement within the expandable member to adjust to a dimension of the expandable member.
