Abstract
A vascular implant for an endoluminal stent or blood vessel, the stent or blood vessel defining a lumen for the passage of blood. The liner can comprise a flexible bladder arrangeable within the lumen, which can be fillable with a compressible fluid. The liner can define an inner lumen for the passage of blood. The liner and the fluid are conformable in response to a pulsatile pressure wave of the blood in the blood vessel such that the pressure within the blood vessel is reduced.
Claims18
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.
A liner for a radially-inextensible lumen within a blood vessel, the liner comprising:
- a flexible bladder arrangeable within the radially-inextensible 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 radially-inextensible 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.
