Beschreibung
Zusammenfassung:	An easy-to-control interventional instrument delivery device, comprising a core tube (7), a guiding head (2) and a fixing head (3) being fixed onto the core tube (7); the guiding head (2) is fixed at a distal end of the core tube (7), and the fixing head (3) extends from a proximal end side of the core tube (7), an interventional instrument mounting position being located between the guiding head (2) and the fixing head (3); the outer periphery of the interventional instrument mounting position is provided with an axially slidable outer sheathing tube (5), further being provided with a floating limiting strip (1); a proximal end of the floating limiting strip (1) is a starting end (13) that is connected near the fixed head (3), and a distal end is a terminal end (11, 101) that floats between the interventional instrument mounting position and the outer sheathing tube (5). The easy-to-control interventional instrument delivery device is capable of fastening an end portion of a valve stent (8) during stent release so as to prevent the stent (8) from completely falling out during release, and reduces the relative friction between the delivery device and the valve during stent release and recovery.
