A Universal Device to Convert a Continuous Flow Assist Device to a Pulsatile Flow Device to Simulate Normal Blood...

Area of Science:

• Biomedical Engineering
• Cardiovascular Devices

Background:

• Continuous flow assist devices (CFADs) are prevalent mechanical circulatory support systems.
• CFADs produce non-physiologic flow, potentially causing complications due to the lack of pulsatility.
• Lack of pulsatility complicates clinical management, leading to undetectable pulses and minimal pulse pressure.

Purpose of the Study:

• To introduce a concept for a universal converter device.
• To enable the conversion of continuous flow to pulsatile flow in existing CFADs.
• To simulate native-like flow and pressure patterns.

Main Methods:

• A conceptual inline universal converter device is proposed.
• The device features two parallel components operating in tandem.
• Specially positioned openings facilitate the conversion of continuous to pulsatile flow.

Main Results:

• The converter aims to provide the benefits of pulsatile physiologic flow after CFAD implantation.
• It can achieve a native-like flow pattern, potentially preventing CFAD-related complications.
• The device offers a method for pulsatility generation and simulation.

Conclusions:

• The presented concept offers a universal add-on solution for CFADs.
• This device can convert continuous flow to physiologic pulsatile flow.
• It has the potential to enhance patient outcomes and management.
