Patent ID: 8617234

Claim:
A system, for treatment of an aneurysm, comprising: a guidewire for guiding the system to an aneurysm; a tubular-shaped device for positioning by a user within a blood vessel for treatment of an aneurysm, the device including a plurality of braided strands of helically-wound material in a lattice structure, wherein the device is self-expandable to a first expanded tubular configuration, such that the device engages an inner surface of a blood vessel with a surface of the device being apposed to the vessel surface, the first expanded tubular configuration having a first porosity in a first portion and in a second portion along a length of the tubular-shaped device, the second portion being adjustable, after engagement of the device with the vessel surface, along a length of the second portion to change the device into a second expanded tubular configuration based on an input by the user while the device remains engaged with the vessel surface, such that the second portion acquires a second porosity, different from the first porosity, while the first portion maintains the first porosity; wherein at least two of the braided strands are formed of different metallic materials; wherein the at least two of the braided strands are of different widths; wherein one of the materials comprises platinum; a device adjuster configured to be positioned in the blood vessel, engage an inner surface of the device while at least a portion of the device adjuster is within the tubular-shaped device, and change the device from the first configuration to the second configuration based on the input; wherein the input comprises movement, by the user, of the device adjuster in contact with the device.
