Abstract: 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.

Abstract: An invasive cardiac valve comprises a tubular stent (1) and a valve (2). One end of the tubular stent (1) is of a frusto-conical structure, the other end is wide open, and the diameter of the open end is greater than the diameter of the frusto-conical end. The valve (2) is attached to the frusto-conical end of the tubular stent (1); and a delivery and retrieval hole (4) of the cardiac valve is provided at the top of the open end of the tubular stent (1). Because the diameter of the open end is greater than the diameter of the frusto-conical end, the cardiac valve can be effectively fixed in a position of aortic annulus to prevent the cardiac valve displacement caused by the impact of the blood flow. Because the valve (2) is attached to the frusto-conical end of the tubular stent (1), the valve (2) can totally avoid the left and right coronary ostia and does not affect the haemodynamics of the coronary artery.
