Choosing Wisely: Optimizing Medical Textiles To Enhance Cardiovascular Devices

By Andrew Metzger and Dan Treusch, Secant Group

Braided, knitted, and woven textiles each bring distinct advantages to cardiovascular devices, from conforming around complex frames to supporting tissue integration and controlling blood flow. Selecting the right structure requires balancing flexibility, porosity, thickness, permeability, and catheter compatibility against the device’s intended function. As minimally invasive procedures expand to younger, lower-risk patients, durability and long-term performance are becoming even more critical. Emerging approaches, including composite materials, nanofiber scaffolds, and polymer coatings, may help address challenges such as thrombosis, tissue regeneration, and mechanical reliability.

Explore how informed textile selection and early collaboration with experienced textile engineers can support more effective heart valves, grafts, occlusion devices, and other next-generation cardiovascular technologies.
