Flow diverting device for chronic inflammation and lymphedema

A flow diverting apparatus includes a stent body and a stent extension. The stent body includes an inlet opening, an outlet opening, and a cavity extending from the inlet opening to the outlet opening. The stent body is configured to pass fluid flow from the inlet opening through the lumen to the outlet opening. The stent body includes a first portion having the inlet opening and a second portion having the outlet opening. The second portion tapers from one end of the second portion to a first position of the second portion, thereby forming a recessed portion having a plurality of holes. The stent extension is configured to be disposed between at least a portion of the recessed portion and the vessel wall to prevent migration of vessel wall cells onto the recessed portion. 一种流动转向设备包括支架主体和支架延伸部。所述支架主体包括入口开口、出口开口和从所述入口开口延伸到所述出口开口的腔。所述支架主体被构造用以使流体流从所述入口开口通过所述腔传递到所述出口开口。所述支架主体包括具有所述入口开口的第一部分和具有所述出口开口的第二部分。所述第二部分从所述第二部分的一端到所述第二部分的第一位置渐缩，从而形成具有多个孔的凹进部分。所述支架延伸部被构造成设置在所述凹进部分的至少一部分与血管壁之间，从而防止血管壁细胞迁移到所述凹进部分上。
