Left ventricular outflow tract stent and delivery system

Abstract

The present invention discloses a left ventricular outflow tract stent and a delivery system. The left ventricular outflow tract stent includes a stent body, the stent body is composed of a plurality of supporting components arranged along a first path coinciding with a left ventricular outflow tract path, each of the supporting components includes an inverted-V-shaped frame and an inverted-trapezoidal frame, and the inverted-V-shaped frames and the inverted-trapezoidal frames are alternately arranged to form peak regions and valley regions; connecting strips are arranged on the supporting components; and the stent delivery system includes a control component, a delivery catheter, an air bag component, a guide component, and a loading component, the air bag component is connected with the control component through the delivery catheter, 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. The control component is configured to control the delivery system to accurately carry and release the stent body on the loading component to a proper position of the left ventricular outflow tract, so that the safety of a minimally invasive surgery is improved.
