Occlusin 500 is a family of biodegradable, dense, hyperechoic microspheres, which are available in a range of calibrated sizes and marketed under the trade name Ekobi Embolization Microspheres. The microspheres consist of poly-DL-lactic-co-glycolic acid (PLGA) coated with bovine collagen. Following injection into the target vasculature, the collagen binds circulating platelets resulting in a platelet-rich clot which occludes the target vasculature. The microspheres slowly degrade and are removed from the body over 4-6 months.
A sterile, bioabsorbable, implantable bead/microsphere intended to be used to temporarily occlude an artery supplying hyperplastic/neoplastic tissue in a variety of anatomies (e.g., liver, lung, breast, bladder, uterus, head or neck); it does not include a pharmaceutical agent. It may be used independently to create ischemia in the tissue, or as an adjuvant in combination with cytostatic agents and other antitumour drugs to help optimize intra-tumour drug accumulation for interventional radiology and visceral surgery procedures. It is typically available as an injectable solution containing numerous microspheres [e.g., degradable starch microspheres (DSM)]. This is a single-use device.
