Zusammenfassung:An intravenous filter comprises a cylindrical holder (1) and a thromboembolus-trapping device in the form of a set of resilient pins (4) secured in the holder. Each pin has an L-shaped grip (5) on its free end. An apparatus for preoperative preparation of the filter comprises an applicator capsule (9) attached to a catheter (11), a guide element (8) comprising conical (20) and a cylindrical (19) portions, a threaded stylet (21) and a collet clamp (17, 18). Preoperative preparation of the filter comprises matching the cylindrical portion of the guide element with the capsule bringing the stylet up through the guide element capsule, catheter and collet, screwing the filter on to the thread, retracting the filter through the guide element into the capsule and removing the guide element. The tightened collet prevents unwanted rotation/unscrewing of the filter.
