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.

Abstract: A catheter system including a delivery sheath and a wire management device. The wire management device is slidably disposed within a lumen of the sheath, and includes a shaft and at least two vane assemblies. The vane assemblies each project from an exterior surface of the shaft and are circumferentially spaced from one another. Further, the vane assemblies are collapsible to a collapsed stated when disposed within the lumen, and are configured to self-expand from the collapsed state toward a normal, expanded state when released from the lumen. The catheter assembly generates a plurality of compartments that are separated from one another by the vane assemblies and along which individual guidewires can be tracked. The compartments maintain the guidewires separate from one to prevent possible twisting. An advancing endograft delivery device tracked over the guidewires collapses the vane assemblies, coalescing the compartments into a single compartment during endograft deployment.
