Absorbable blood vessel filter

Abstract

An absorbable vascular filter is disclosed for deployment within a blood vessel for temporary filtration of bodily fluids. One embodiment is configured for placing such an absorbable vascular filter within the inferior vena cava (IVC) to filter emboli and prevent pulmonary embolism (PE) in time for a limited period of time. Once protection of the PE is completed, the filter will be biodegraded according to a planned schedule determined by the absorption characteristics of the filter component. Thus, the temporary absorbable vascular filter avoids long-term complications of permanent IVC filters, such as avoiding increased deep vein thrombosis, adjacent organ puncture and embolism caused by filter rupture, while also avoiding the removal requirements of metal recoverable IVC filters.

Although these types of retrievable filters are intended to be removed over a period of several months, some studies have shown that approximately 70%-81% of patients with retrievable IVC filters do not return to the hospital to remove Thousands of patients have suffered life-threatening adverse events from long-term retrievable IVC filter placement [41,44,46-48]
