Development of porous and patient specific shape memory polymer composites as an embolic agent for endovascular embolization

Abstract

The objective of the present work is to develop a radiopaque porous and patient specific shape memory polymer SMP based embolizing agent for interventional radiology technique that overcomes the limitations of the currently used embolic agents In this regard a novel fabrication technique has been developed by combining extrusion fused filament fabrication FFF and salt leaching process to produce the patient specific porous composites Initially tungsten 7wt as a radiopaque filler a...
