Abstract

A device and method for loading an implant into a delivery system are disclose which are capable of simplifying operations required in interventional surgery using the implant. The device includes a guide cap (1), a guider (2) and a guiding tube (3). The guide cap (1) has a conical section (101) and a straight or conical tube (103) in communication with a small open end (102) of the conical section, and the conical section has a large open end (104) that flares outward, thereby forming a flange (105) facing the tube (103). The guider (2) has tapered sections (9, 10) that are tapered along an axis of the guider and thus form large and small open ends (8, 11). The small open end (11) has a diameter greater than a diameter of the small open end (102) of the conical section of the guide cap (1). The guide cap (1) and the guider (2) are so sized that the flange (105) can cover and be locked to the guider (2), with an end portion of the straight or conical tube (103) protruding from the small open end (11) of the guider (2). The guiding tube (3) is a round tube with two open ends, in which the first open end has a diameter greater than the diameter of the small open end (102) of the coni…
