CANCER CELL-TRAPPING METAL FILTER, CANCER CELL-TRAPPING METAL FILTER SHEET, CANCER CELL-TRAPPING DEVICE, AND MANUFACTURING METHODS THEREFOR

摘要

Provided are a cancer cell-trapping metal filter with a high opening area ratio, a cancer cell-trapping metal filter sheet, and a cancer cell-trapping device using the cancer cell-trapping metal filter, as well as manufacturing methods therefor. With the cancer cell-trapping metal filter (1), it is possible, as a result of the openings of linked through holes (12) provided in a metal sheet (11) being wave-shaped, to extract CTCs from other components utilizing the hole diameter of the short sides thereof, and as a result of the openings having a wave-like shape, to draw the linked through holes closer to each other while maintaining CTC-trapping ability. Consequently, it is possible to increase the opening area ratio in the cancer cell-trapping metal filter (1).
