1. A liner for a vascular implant, the vascular implant defining a lumen for the passage of blood through a blood vessel, the liner comprising:
a flexible bladder arrangeable within the lumen and fillable with a compressible fluid, the bladder defining an inner lumen for the passage of blood; and
a plurality of discrete fillable portions extending primarily along a length of the inner lumen, the plurality of discrete fillable portions fluidly interconnected with one another;
wherein the bladder and the fluid are conformable in response to a pulsatile pressure wave of the blood in the blood vessel such that the lumen can continually deform to mimic a healthy vessel such that the pressure within the blood vessel is reduced.
