Long Term Retrievable Venous Filter

Available for licensing and commercialization is a novel long-term or biodegradable retrievable vena cava (IVC) filter that can be retrieved indefinitely regardless of the time it was placed, or alternatively dissolves without being removed, leaving no clinically relevant traces of its presence. IVC Filters are underutilized due to the complications associated with chronic indwelling, and long-term consequences of IVC filters (like chronic venous insufficiency and venous stasis) has an uncertain, but high incidence. IVC filters would be more widely used for short-term prophylaxis against one of the most underdiagnosed and deadly hospital-acquired diseases, namely pulmonary embolism. Patients with burns, trauma, or undergoing orthopedic procedures like hip replacement are at high risk for venous clots, which could then migrate to the lung, which can be lethal. This design leaves in only several small mm long struts that are coated with drugs that prevent early clot formation on the struts and legs of the filter. The device includes struts that, upon removal of the filter, separate from the filter legs mechanical or electrical means and are left behind permanently embedded within the venous wall. Other designs include filters made from biodegradable polymers that dissolve over time without requiring removal. This biodegradable filter may suit patients with temporary needs for protection (patients with prolonged immobility, hip replacement, trauma, intensive care patients).
