Evaluation of FlowMod System While Intermittently Partially Occluding Vena Cava Blood Flow in Subjects With ADHF (FLOW-HF)

3 settembre 2026 aggiornato da: FlowMod, Inc.

An Evaluation of the FLOWMod System to Occlude Vena Cava Blood Flow in Subjects With Acute Decompensated Heart Failure

FLOW-HF will assess the impact of intermittent partial occlusion of the SVC and/or IVC, the cardiac filling pressure and the difference of effects between the two occlusion locations (SVC and IVC) using the FlowMod flow modulating device on select parameters in subjects experiencing ADHF (Acute Decompensated Heart Failure)
