• Microfluidics

Background:

• The human vasculature, including the cardiovascular and cerebrovascular systems, is vital for life.
• Malfunctions in blood vessels can lead to severe health conditions like heart attack and stroke.
• Studying intact human blood vessels is challenging due to accessibility and technical difficulties.

Purpose of the Study:

• To review microdevices designed to mimic human vasculature.
• To highlight the potential of microdevices as alternatives to traditional tissue models.
• To focus on microdevices replicating cardiovascular and cerebrovascular systems.

Main Methods:

• Review of existing literature on microdevices for vascular modeling.
• Analysis of microdevices fabricated in 2D and 3D configurations.
• Discussion of microdevices mimicking physiological properties of blood vessels.

Main Results:

• Microdevices offer a viable alternative to human tissue models for vascular research.
• Various microdevices have been developed to replicate specific aspects of the vasculature.
• Both 2D and 3D microdevices show promise in simulating cardiovascular and cerebrovascular functions.

Conclusions:

• Microdevices are emerging as powerful tools for studying vascular diseases and physiology.
• Further development of microdevices will enhance our understanding of the cardiovascular and cerebrovascular systems.
• These engineered systems hold potential for drug screening and personalized medicine.
