ABSTRACT:
Angiographic vascular occlusion agents comprising a biopolymer alone or in combination with platelet-rich plasma. A liquid biopolymer gels in situ in contact with divalent cations. Biopolymer agent achieves permanent occlusion, biopolymer combined with the platelet-rich plasma achieves temporary or semi-permanent occlusion. The plasma is obtained from the patient's own blood to avoid undesirable immunogenic reactions. The occlusion agents have strong occlusive properties when injected into a bleeding vessel.
