Self-extendable stent for pulmonary artery

Abstract

The invention relates to a self-expandable stent, especially a pulmonary stent, with 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 arranged at the middle section thereof, a skirt surrounding the dry valve at least at the middle section and made of one of bovine pericardium and polyester, wherein the stent further comprises eyelets arranged at a distal end at the distal section and/or a proximal end at 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, the middle 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. The invention further relates to A delivery device for delivering a self-expandable stent according to claims 1 to 14, 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, and/or wherein the actuation mechanism has a torque control and can rotate the stent about an axis of the main body, and/or the delivery device having a knob or the like at the actuation mechanism, with the knob in particular being able to be rotated about an axis of rotation of the actuation mechanism.
