Area of Science:

  • Biomedical Engineering
  • Computational Mechanics
  • Materials Science

Background:

  • Myocardial infarction causes irreversible heart damage, potentially leading to heart failure.
  • Treating myocardial infarction is challenging due to the anisotropic nature of the heart's fibrous structure.
  • Patches and cardiac restraint devices offer promising therapeutic strategies for post-infarction care.

Purpose of the Study:

  • To develop a model-assisted method for designing patterned membranes for post-infarction treatment.
  • To optimize design parameters for patterned membranes using computational and statistical models.
  • To create customized membranes with patient-specific technical specifications.

Main Methods:

  • Utilized a combination of computer experiments and statistical models.
  • Employed finite element modeling (FEM) and global sensitivity analysis.
  • Integrated random forest and response surface models for metamodeling.

Main Results:

  • Developed a metamodel-based design method for rapid estimation of membrane properties (e.g., Young's modulus).
  • Successfully applied the method to design a functional membrane.
  • Validated optimization results through subsequent laboratory measurements.

Conclusions:

  • The proposed metamodel-based approach enables efficient and accurate design of patterned membranes.
  • This method facilitates the creation of customized cardiac patches tailored to individual patient needs.
  • Opens new avenues for developing advanced medical devices for cardiovascular disease treatment.
