The present invention relates to an endoluminal delivery cannula, for delivery of a substance to an extravascular target site via the vascular system of a human or animal body, wherein the cannula comprises a proximal cannula hub, an elongated proximal, and a tip portion. The tip is tapered towards the distal tip which is preferably provided with a pointed tip for penetrating tissue. The pointed tip may comprise at least one primary facet and two secondary facets, wherein the two secondary facets are arranged proximally of said primary facet. An endoluminal delivery assembly comprises the cannula, a protective catheter adapted for insertion into the vascular system of a human or animal body, and a proximal catheter hub provided at the proximal end of the catheter and adapted for guiding the catheter through the vascular system. |
