Fabrication of strong, bioactive vascular grafts with PCL/collagen and PCL/silica bilayers for small-diameter vascular applications

Materials & Design, 2019
In vascular surgical applications, small-diameter vascular grafts made from synthetic polymers are rarely commercialized, owing to delayed reendothelialization and subsequent thrombus formation and occlusion.

Trans-prosthetic recanalization of a collapsed iliac limb using the GoBack catheter: a case report

CVIR Endovascular, 2021
Background Recanalization of graft limb occlusion can prove challenging and the use of the GoBack crossing and reentry device may be a suitable option, especially when there is no other way to restore flow with an usual endovascular approach.

Vascular replacement using a layered elastin-collagen vascular graft in a porcine model: one week patency versus one month occlusion [PDF]

Organogenesis, 2015
A persistent clinical demand exists for a suitable arterial prosthesis. In this study, a vascular conduit mimicking the native 3-layered artery, and constructed from the extracellular matrix proteins type I collagen and elastin, was evaluated for its performance as a blood vessel equivalent.
