A FLOW DIVERTING APPARATUS FOR CHRONIC INFLAMMATION AND LYMPHEDEMA
20250073015 · 2025-03-06 ·

A flow diverting apparatus includes a stent frame body, and a stent frame extension.

The stent frame body includes an inlet opening, an outlet opening, and a cavity extending from the inlet opening to the outlet opening. The stent frame body is configured to pass a flow of fluid from the inlet opening to the outlet opening through the cavity. The stent frame body includes a first portion having the inlet opening, and a second portion having the outlet opening. The second portion is tapered from one end of the second portion to a first location of the second portion, thereby forming an indented portion having a plurality of pores. The stent frame extension is configured to be disposed between at least a portion of the indented portion and a vessel wall, thereby preventing a migration of vessel wall cells onto the indented portion.
