1. A system comprising a left ventricular outflow tract stent and a delivery system, wherein the left ventricular outflow tract stent comprises a stent body, the stent body is composed of a plurality of supporting components arranged along a first path configured to coincide with a left ventricular outflow tract path, and the supporting components form a ring structure;
each of the supporting components individually comprises one of both an inverted-V-shaped frame and an inverted-trapezoidal frame, and the inverted-V-shaped frames and the inverted-trapezoidal frames of all of the supporting components are alternately arranged to form peak regions and valley regions;
the left ventricular outflow tract stent further comprises connecting strips, and the connecting strips are arranged on the supporting components for storage and fixation of the stent body;
the delivery system using the left ventricular outflow tract stent comprises a control component, a delivery catheter, an air bag component, a guide component, and a loading component, the control component is configured to control the entire delivery system, the air bag component is connected with the control component through the delivery catheter to control the contraction and expansion of an air bag, the guide component is arranged at an end of the air bag component away from the delivery catheter, and the loading component is arranged at an end of the guide component away from the air bag component for storage and carrying of the stent body; and
the loading component comprises an optical channel, a first reflecting component, a second reflecting component, and a first medium component, the optical channel is arranged at the end of the guide component, a light source is arranged in the optical channel and acts in the optical channel, the first reflecting component is arranged at the periphery of the optical channel and surrounds the optical channel, first light-pervious regions are alternately arranged on a surface of the first reflecting component, the second reflecting component is arranged at the periphery of the first reflecting component, a first gap is formed between the second reflecting component and the first reflecting component, the first medium component is arranged in the first gap, and the position of the first medium component corresponds to the first light-pervious regions.
