Abstract
An intervention guidance device () includes a main body portion () and a guidance portion (). The guidance portion () has a contracted configuration and an expanded configuration. In the expanded configuration, the guidance portion () has a central area () and a closed outer edge (). In the contracted configuration, the outer edge () is farther away from the main body portion () than the central area (), and the guidance portion () is restorable from the contracted configuration to the expanded configuration. In the intervention guidance device (), the radial dimension of the guidance portion () is larger than the distance between the chordae tendineae, so that an effective access path that does not cross the chordae tendineae can be established, the subsequent implantation of a heart valve prosthesis does not pass through the chordae tendineae, and the success rate of a heart valve prosthesis implantation surgery can be improved.
