Abstract
The present disclosure provides for a double cone filter and a delivery apparatus for deploying the filter within the body. The filter may have superior and inferior rings connected to each other by a plurality of connectors. The rings may have a first degradation rate, and the connectors may have a second degradation rate. The second degradation rate may be faster than the first degradation rate, such that the connectors degrade faster than the rings. In this way, the filter has a filtering state when the connectors are present. After the connectors degrade or partially degrade, the rings may relax against the vessel wall in an open state. After a sufficient length of time, the rings also degrade such that the filter is completely removed from the body.
