1. A device to treat an aneurysm comprising:
- at least one core member including a distal end, that is inserted into the aneurysm; and
at least one longitudinal flexible member, wherein the longitudinal flexible member is attached to the core member, wherein the longitudinal flexible member is wound with multiple complete rotations around the at least one core member within the aneurysm, wherein the device is in a first state prior to insertion of the core member into the aneurysm wherein the longitudinal flexible member is wound a first number of complete rotations around the core member and this first number can be zero, wherein the device is in a second state after insertion of the core member into the aneurysm wherein the longitudinal flexible member is wound a second number of complete rotations around the core member and this second number is greater than the first number, and wherein accumulation of the at least one longitudinal flexible member within the aneurysm reduces blood flow into the aneurysm; and
a guide loop that guides the longitudinal flexible member as the longitudinal flexible member winds around the core member and that encircles the core member, including the distal end of the core member, in a plane which is substantially parallel to the rotational axis of the core member while the longitudinal flexible member winds around the core member.

Abstract
This invention is a device and method for reducing blood flow into an aneurysm, especially a cerebral aneurysm, in order to promote therapeutic embolization of the aneurysm. The device comprises: at least one core member that is inserted into the aneurysm; and at least one longitudinal flexible member that is wound repeatedly around the core member within the aneurysm. The longitudinal flexible member is wound around the core member until the rotational accumulation of the flexible member reduces blood flow into the aneurysm and promotes therapeutic embolization of the aneurysm.

9. A device to treat an aneurysm comprising:
-
at least one core member including a distal end, that is inserted into the aneurysm; and
at least one longitudinal flexible member, wherein the longitudinal flexible member is attached to the core member, wherein the longitudinal flexible member is wound with multiple complete rotations around the at least one core member within the aneurysm, wherein the device is in a first state prior to insertion of the core member into the aneurysm wherein the longitudinal flexible member is wound a first number of complete rotations around the core member and this first number can be zero, wherein the device is in a second state after insertion of the core member into the aneurysm wherein the longitudinal flexible member is wound a second number of complete rotations around the core member and this second number is greater than the first number, wherein the longitudinal flexible member accumulates around the core member in an outwardly-expanding manner, and wherein accumulation of the at least one longitudinal flexible member within the aneurysm reduces blood flow into the aneurysm, and wherein the at least one longitudinal flexible member is wound repeatedly around the at least one core member by one or more rotations selected from the group consisting of;
rotation of the at least one core member; and
rotation of the longitudinal flexible member around the core member; anda guide loop that guides the longitudinal flexible member as the longitudinal flexible member winds around the core member and that encircles the core member, including the distal end of the core member, in a plane which is substantially parallel to the rotational axis of the core member while the longitudinal flexible member winds around the core member. - View Dependent Claims (10, 11, 12, 13)
