Abstract:
1. A system, for treatment of an aneurysm, comprising: a guidewire for guiding the system to an aneurysm; a stent, for implanting in a patient's vessel, comprising: a plurality of braided strands; a proximal portion having a proximal end; a distal portion having a distal end; a stent length extending from the proximal end to the distal end; a stent wall that defines a lumen extending between the proximal end and the distal end, the stent wall having a delivery configuration and an expanded configuration, the stent wall being self-expandable to the expanded configuration, such that the stent wall engages an inner surface of the vessel with an outer surface of the stent wall being apposed to the vessel surface, the stent wall having a self-expanded porosity while in the expanded configuration; wherein, when in the expanded configuration and while the stent wall remains engaged with the vessel surface, the stent wall has a porosity that is changeable in a discrete location proximal to the distal portion by changing the stent length by a user input, such that the discrete location transitions from the self-expanded porosity to an adjusted porosity, while the distal portion maintains the self-expanded porosity; and a stent adjuster configured to engage an inner surface of the stent while at least a portion of the stent adjuster is within the stent and change the stent from the expanded configuration to the adjusted configuration based on the input comprising movement, by a user, of the stent adjuster while engaged with the inner surface of the stent; wherein the plurality of braided strands comprises a first plurality of strands of a first metallic material and a second plurality of strands, of a second metallic material, different from the first material, wherein each of the first plurality of strands has a first width and each of the second plurality of strands has a second width, different than the first width; wherein the first material comprises platinum.
