Micrograft for the treatment of intracranial aneurysms and method for use

A vascular graft configured for occluding a vasculature of a patient, the vascular graft comprising:

• an absorbent biocompatible textile structure forming a tubular structure;
• and
• a core element having a proximal end, a distal end and a lumen within the core element, the core element positioned inside the biocompatible structure and attached to the biocompatible structure for implantation with the biocompatible structure within the vasculature, the core element having a coiled structure having multiple coils and a gap between adjacent coils;
• a tube secured to the core element for implantation with the biocompatible structure within the vasculature, wherein a distal portion of the tube is within the textile structure, the tube having a lumen extending therethrough from a distal opening to a proximal opening to enable blood flow into and out of the tube, the tube seated within the coils so as to engage in the gap between adjacent coils;
• the vascular graft forms a capillary tube wherein a capillary effect is created within the vascular graft when the biocompatible structure is exposed to blood such that blood is transported in a proximal direction through the vascular graft wherein blood clots.
