Relief Cardiovascular develops a transcatheter smart implant—the Relief System—to autonomously monitor and modulate inferior vena cava flow for chronic heart‑failure patients with diuretic‑resistant congestion. The implant provides continuous preload adjustment, aiming to improve renal perfusion, reduce hospitalizations, and enable personalized hemodynamic therapy. The company generates revenue through device sales and associated monitoring services once the system receives regulatory clearance.

Problem
Congestive heart failure leads to fluid overload, causing significant patient distress and requiring frequent hospitalizations for symptom management. Current treatment strategies often rely on subjective assessments and reactive interventions, failing to proactively address fluid accumulation. Existing monitoring methods are invasive or lack the ability to provide real-time, closed-loop control of fluid balance.
Solution
Relief Cardiovascular is developing a closed-loop transcatheter implant designed to provide continuous monitoring and automated fluid management for heart failure patients. The implant uses real-time physiological data to detect fluid congestion early, triggering automated adjustments to maintain optimal fluid balance. This proactive approach aims to reduce the frequency of hospitalizations, improve patient quality of life, and alleviate the symptoms associated with congestive heart failure. By providing a closed-loop system, the device offers a more precise and responsive method for managing fluid overload compared to traditional methods.
Target Audience
The primary target audience includes heart failure patients at risk of fluid overload and the cardiologists who manage their care.
Features
- Closed-loop system for automated fluid management
- Real-time monitoring of physiological parameters related to fluid status
