MECHANICAL CHARACTERISATION OF ELECTROSPUN MEMBRANES FOR THE REPAIR ANDREGENERATION OF PELVIC FLOORAbstract:Pelvic organ prolapse (POP) is one of the most common chronic disorder in women, impacting thequality of life of millions of them worldwide. Since their first introduction, surgical meshes havedramatically transformed POP repair, showing superior anatomic outcomes in comparison to traditionalapproaches. Nevertheless significant progress has been attained, there are still unmet clinical needs interms of biocompatibility, mechanical properties, failure and complication rates. Regarding themechanical behaviour of prosthetic implants for POP repair, this is an important factor in ensuring theirfunctionality and integration into the host tissue. Moreover, matching mechanical properties, mainly ina physiological loading range is a desirable requirement towards reducing clinical complications.The aimof this project is to evaluate the mechanical behaviour of novel electrospun membranes for POP repair,based on the blend of two polymers at different concentrations.The work will be based on the development of an experimental protocol, which will include:uniaxialtension evaluation, cyclic loading, and test of the membranes in dry as well as wet conditions.Overall, the project will be carried out through multiple steps, which are summarised here below:1) analysis of the current literature;2) development of an experimental protocol;3) experimental set-up development and characterisation of the samples;4) analysis of the results;5) discussion and report.Reference:1.
