Surgeons and politicians are demanding the immediate withdrawal of mesh implants made with Chinese plastic.

The calls come following claims that polypropylene resin, sourced by medical manufacturer Boston Scientific (BSc) from China and made into permanent implants, could degrade within months.

One of the world’s top plastics experts, Duane Priddy, told US television current affairs programme 60 Minutes, that implants made of the material could only “last months” instead of up to 40 years.
