摘要： An implant delivery device (100) includes a casing (110); and inner and outer tube driving members (150, 160), an inner tube (120), an intermediate tube (130), an outer tube (140) and an air-evacuation locking assembly (170), each at least partially accommodated in the casing (110). The three tubes are sequentially nested in one another, and first, second and third spaces are formed between neighbouring tubes. The inner tube driving member (150) has a proximal end that is sealingly fixed to a proximal end of the inner tube (120), and the outer tube driving member (160) is sealingly fixed to a proximal end of the outer tube (140). The intermediate tube (130) has a proximal end that is sealingly fixed to the inner tube driving member (150), and the intermediate tube extends through and is sealingly connected to the outer tube driving member (160). The air-evacuation locking assembly (170) is detachably coupled to the inner tube driving member (150). The inner tube driving member (150) and the air-evacuation locking assembly (170) are provided with first and second air-evacuation channels (A, B), respectively. When the air-evacuation locking assembly (170) is coupled to the inner tube driving member (150), the second air-evacuation channel (B) is brought into communication with the second and third spaces via the first air-evacuation channel (A) and the first space. The inner tube driving member (150) is coupled to the casing (110) by the air-evacuation locking assembly (170). When the air-evacuation locking assembly (170) is disconnected from the inner tube driving member (150), the inner tube driving member (150) remains in slidable connection with the casing (110).

摘要： 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 conical section of the guide cap and smaller than the diameter of the small open end (11) of the guider.

摘要： A drive handle and system for delivering an implant are disclosed. The drive handle includes a manual control unit, an electrical control unit and a transmission mechanism. The manual control unit is connected to the transmission mechanism to actuate the transmission mechanism to drive a delivery catheter for delivering the implant. The electrical control unit is connected to the transmission mechanism to actuate the transmission mechanism to drive the delivery catheter. The drive handle is switchable between a manual drive/control mode and an electrical drive/control mode to drive the delivery catheter to deliver the implant. The operation is simple, and the operating physician can take full advantage of the two modes to perform the surgical procedure based on his/her own operational preferences. This can result in higher surgical accuracy. Further, by providing these two modes, the apparatus has an increased the security and a reduced surgical risk.

摘要： An implant capsule (10) and an implant delivery system are disclosed. The implant capsule (10) includes, sequentially from a proximal end to a distal end, a flexural section (102, 102a-102e), a reinforcement section (101, 101a-101e) and a radiopaque reinforcement ring (104a-104e). The reinforcement section (101, 101a-101e) has higher strength than the flexural section (102, 102a-102e). The implant delivery system includes the implant capsule (10). The implant capsule (10) can ensure the implant to be deployed in a coaxial condition and prevent over-expansion due to large expansion forces exerted by a stent of the implant.
