Title: APPARATUS FOR EXTRUDING A STRUCTURED EXTRUDATE
Abstract:
The invention relates to an apparatus for extruding a structured extrudate which can be introduced into a human or animal body. Said apparatus comprises an extrusion device with a housing, said housing having a peripheral lateral wall which is provided with a nozzle wall having an outlet nozzle and with a spindle sleeve upstream thereof in the direction of production, the space in the housing between the spindle sleeve, the lateral wall and the outlet nozzle delimiting an extrusion space and the housing being provided with a polymer feeding device in the area of the extrusion space. At least one guide channel is formed in the spindle sleeve and extends in the direction of production so that at least one rod-shaped body can be introduced into the extrusion space by the device for feeding rod-shaped bodies, the at least one guide channel being arranged in approximate rectilinear alignment with the outlet nozzle.
