摘要：
A device and method for predictably controlling the collapsing of a collapsible and expandable stent for subsequent translation through a delivery sheath lumen to an anatomical target such as a heart valve or intravascular location for expansion and implantation. The loading device defines an inner lumen comprising a successively decreasing, from the proximal to the distal direction, inner diameter alternating between two sections of decreasing diameter and two sections of constant diameter until reaching the inner diameter of the delivery sheath. A fluid-filled reservoir is provided at the proximal end of the loading device that is configured to provide moisture or wetting for materials associated with or attached to the stent that require moisture retention. Thus, as the stent is being collapsed with the loading device, at least a portion of the stent may be immersed in the fluid reservoir to preserve the subject material.本發明揭示一種用於可預測地控制一可折疊且可展開支架之折疊以用於透過一輸送鞘管腔至一解剖目標(諸如一心臟瓣膜或血管內位置)之後續平移以用於展開及植入的裝置及方法。裝載裝置界定一內管腔，該內管腔包括自近端至遠端方向之一依次遞減、在兩個遞減直徑區段與兩個恆定直徑區段之間交替直至達到輸送鞘的內徑。一流體填充儲槽係提供於該裝載裝置的近端處，其經構形以提供與需要保濕之支架相關聯或經附接至支架的材料的濕氣或潤濕。因此，當支架與裝載裝置一起折疊時，支架的至少一部分係可浸沒於流體儲槽中，以保存主體材料。
