摘要:
An artificial blood vessel is formed of a tubular body of composite fibers. The composite fibers are composed of a polyethylene terephthalate and a polyester elastic body which are materials familiar with the tissue of an organism. The tubular body is produced by weaving, knitting or assembling processing, or the combined processing thereof, of the composite fibers.

A vascular prosthesis is disclosed which excels in expansibility and allows satisfactory attachment thereto of cells and tissues. This vascular prosthesis is obtained by air-jet entangling a mass of yarns containing in at least a part thereof an elastic bulked yarn in order to get an entangled yarn furnished with fine crimps formed in fiber thereof, and fabricating a tubular fabric of the entangled fiber by one treatment selected from among weaving, knitting, and braiding treatments.
摘要:
A filter for removing leukocytes and thrombocytes from a solution containing blood components, such as CRC, comprises a filter material having a first surface serving as an inlet surface and a second surface serving as an outlet surface. The outlet surface has a positive zeta potential greater than that of the inlet surface in an electrolyte solution having a pH value of 5.0 to 7.0.
