High Structural Stability of Textile Implants Prevents Pore Collapse and Preserves Effective Porosity at Strain

High Structural Stability of Textile Implants Prevents Pore Collapse and Preserves Effective Porosity at Strain

Reinforcement of tissues by use of textiles is encouraged by the reduced rate of recurrent tissue dehiscence but for the price of an inflammatory and fibrotic tissue reaction to the implant. The latter mainly is affected by the size of the pores, whereas only sufficiently large pores are effective i...
