Patent ID: 8246876

Claim:
A method for making embolization particles for occluding fluid flow through a body vessel, the method comprising: moving an elongated body of biocompatible material relatively towards a guide member and a cutting device, the elongated body defined by extrusion of a body cross-section along a longitudinal axis, the guide member having an opening formed therethrough for guiding the elongated body toward the cutting device; tensioning the elongated body between at least two tensioning members, the tensioning members being longitudinally spaced apart along the elongated body; coating the elongated body with a medicant; feeding the elongated body through the opening of the guide member toward the cutting device, the guide member being disposed downstream of the tensioning members; and cutting the elongated body with the cutting device at a plurality of locations along the longitudinal axis to form the embolization particles such that each of the embolization particles has a particle cross-section that substantially matches the body cross-section.
