The treatment of pathologies, biotransport, and fluid–structure interaction problems in biomechanics

Development of patient-specific modeling has emerged as the key driver of medical research during the past decade. Design of many medical devices and prediction of disease progression require biomechanical assessment as to their suitability for a patient, given specific data such as age and anatomical images. For instance, medical devices and surgical procedures include ventricular assist devices and balloon angioplasty in the cardiovascular system, and presbyopia for cataract treatments in the ocular system. While components of the human body influence bidirectional interactions between tissue and blood and between solid constituents and interstitial flow, these problems are still modeled separately by solid, blood, and interstitial fluid, in which those interactions can be neglected: such biological systems will be analyzed by both solid and fluid biomechanics communities. In this special issue, we highlight advanced articles that were presented on the above problems from either a solid mechanics perspective or from a fluid mechanics perspective, and also those which account for the interaction between solid and fluid
