Abstract

The present invention relates to an aneurysm stent having a base and connector. The base has a vessel facing side and an aneurysm facing side, and is shaped to cover an aneurysm sufficiently. The connector is coupled to the aneurysm facing side of the base such that when deployed the connector is adapted to extend partially into the aneurysm to anchor the base about the aneurysm and alter flow into the aneurysm. Further, the stent can be used as a delivery mechanism to deliver growth factor.

Claims

1-42. -42. (canceled)

43. An apparatus to inhibit flow to an aneurysm packed with coils, the apparatus comprising:

a base having a vessel facing side and an aneurysm facing side;

the base when deploy being larger than a neck of the aneurysm and comprising a shape sufficient to cover the neck of the aneurysm; and

a connector attached to the aneurysm facing side of the base, the connector comprising at least a connector coil, the connector and connector coil is adapted to extend from the base only partially into the aneurysm, the connector coil couples to the coils packed in the aneurysm when deployed,

wherein the connector is adapted to anchor the base about the aneurysm to inhibit flow into the aneurysm.

44. The apparatus according to claim 43, wherein the connector and connector coil are specially designed not to pierce a wall of the aneurysm.

45. The apparatus according to claim 43, wherein the coils packed in the aneurysm comprise Guglielmi Detachable Coils.

46. The apparatus according to claim 43, wherein the connector coil is a Guglielmi Detachable Coil.

47. The apparatus according to claim 43, wherein the base comprises graft material.

48. The apparatus according to claim 43, wherein the base comprises self-expanding material such that the base can be delivered in a small package and expands on deployment to cover the aneurysm.

49. The apparatus according to claim 48, wherein the base also comprises graft material.

50. The apparatus according to claim 48, wherein the self-expanding material comprises a shaped memory alloy.

53. The apparatus according to claim 43, wherein the base resides completely in the vessel.

54. The apparatus according to claim 43, wherein the aneurysm facing side is coated with an adhesive.

55. The apparatus according to claim 43, wherein the base comprises a growth factor.

57. An aneurysm treatment system, comprising:

a plurality of guglielmi detachable coils adapted to be packed in the aneurysm;

an aneurysm base, the aneurysm base when deploy being larger than a neck of the aneurysm and comprising a shape sufficient to cover the aneurysm;

at least one connector coupled to the base adapted to have a portion that extends only partially in the aneurysm; and

the portion of the at least one connector that extends only partially in the aneurysm adapted to couple to the plurality of guglielmi detachable coils adapted to be packed in the aneurysm.

58. The aneurysm stent treatment system according to claim 57, wherein the at least one connector is coupled to a geometric center of the base.

59. The aneurysm stent treatment system according to claim 58, wherein the at least one connector is at least two connectors, each connector adapted to extent only partially in the aneurysm.

60. The aneurysm stent treatment system according to claim 57, wherein the base has a vessel side and an aneurysm side, the vessel side comprises a layer of biocompatible material that promotes permanent fixation of the stent

61. The aneurysm stent treatment system according to claim 60, wherein the biocompatible material is a graft coated with a material to stimulate cell growth

62. The aneurysm stent treatment system according to claim 61, wherein the material to stimulate cell growth is a growth factor.
