Self-extendable stent for pulmonary artery

A delivery device for delivering a self-expandable stent:

• the self-expandable stent comprising:
• a proximal section, a middle section and a distal section arranged at a longitudinal axis of the stent, the stent having a dry valve made of bovine pericardium with a calcium content selected in a range of 0.01 to 0.1 g/Kg arranged at the middle section thereof, wherein the dry valve is rehydrated with a saline solution upon placement at a point of interest with the delivery device, a skirt surrounding the dry valve at least at the middle section, the skirt comprising at least one of bovine pericardium and polyester, wherein the stent further comprises eyelets arranged at at least one of a distal end of the distal section and a proximal end of the proximal section for fixing the stent at an artery, and wherein the stent comprises a frame composed of a plurality of arms forming the proximal section, the middle section and the distal section with the sections being interconnected, and the stent comprising a fixture area at the middle section of the frame with the arms being arranged in parallel to each other at the fixture area and the middle section comprising one or more fixture openings at said fixture area for fixing the valve at the frame, with said fixture openings being present in the arms or respectively between the arms which are directly connected to one another;
• and
• the delivery device comprising:
• a flush port;
• a main body part for holding, inflating and/or releasing the stent;
• and
• an actuation mechanism for moving the stent to a delivery site, wherein the actuation mechanism has a torque control and can rotate the stent about an axis of the main body;
• and
• the delivery device having a knob at the actuation mechanism, with the knob in particular being able to be rotated about an axis of rotation of the actuation mechanism.
