FILTER FOR FLOW IMPROVEMENTS FOR DELIVERY OF BIOMATERIALS

摘要

A flow delivery system includes a syringe and a needle and/or a catheter that delivers an aqueous solution, e.g., a biomaterial alone or mixed with a fluid lubricant, into a body. A filter located within the body of the syringe includes a plurality of openings each of a predetermined size. As the solution travels through the syringe, the solution encounters the filter openings which downsize any biomaterial particles larger than the size of the openings. Also, the filter openings allow any particles of the biomaterial originally smaller than the size of the openings to pass without any downsizing. The size of the filter openings is selected as a function of the size of the opening in the needle and/or catheter. The downsized particles then pass with any other non-downsized particles in a relatively unobstructed manner into the body through the needle and/or catheter.
