From Which Medical Device
The Optease filter is a retrievable filter that can be inserted via femoral, jugular or antecubital routes. The filter comes compressed in a plastic tube for insertion, marked for the appropriate insertion route. This nitinol hypotube filter is a modified version of the permanent TrapEase filter. It has a double-basket design for dual-level filtration and has side struts with unidirectional fixation barbs to protect against cephalad migration. It can be inserted via jugular, femoral or antecubital approaches but has a hook at the caudal end only and therefore may be retrieved only by a femoral approach.
Although the filter is removable it is recommended not to leave it longer than 23 days.
