4:03 PM Abstract No. 280 Resorbable polydioxanone inferior vena cava filter infused with bismuth nanoparticles as radiopacifer agent

Polydioxanone (PPDO) is a resorbable polymer that has been shown to be effective resorbable inferior vena cava filters (IVCF) in preventing pulmonary embolism (PE). However, PPDO is radiolucent with no intrinsic capability for radiographic visualization. Here, we synthesized bismuth nanoparticles (BiNPs) and infused unto PPDO, making it visible by x-ray and computed tomography (CT). This enhanced radiopacity will allow placement accuracy during device implantation and continuous monitoring of the structural integrity of the device to check for fracture or device failure post implantation.
