Indications for Use
The ALN Optional Vena Cava Filter is indicated for the prevention of recurrent pulmonary embolism via placement in the vena cava in the following situations: - Pulmonary thromboembolism when anticoagulants are contraindicated: - Failure of anticoagulant therapy in thromboembolic diseases; - Emergency treatment following massive pulmonary embolism where anticipated benefits of conventional therapy are reduced; and - Chronic, recurrent pulmonary embolism where anticoagulant therapy has failed or is contraindicated. The ALN Optional Vena Cava Filter may be retrieved according to the instructions supplied in the Instruction For Use of the ALN Extraction Kit. Extraction kit: The ALN Optional Vena Cava Filter Extraction Kit has been designed for the removal of an implanted ALN Optional Vena Cava Filter in patients who no longer require a filter. The retrieval of the filter can be performed only by jugular approach.
Device Story
Device consists of 9-leg 316L stainless steel vena cava filter and 8-arm 316L stainless steel retrieval forceps. Filter delivered via 7F sheath using jugular, brachial, or femoral approach; retrieval performed via jugular approach. Designed to trap free thrombus in vena cava. Used in clinical settings by physicians. Output is physical capture of thrombus; retrieval kit allows removal when filter no longer needed. Benefits include prevention of pulmonary embolism in high-risk patients where anticoagulation is contraindicated or ineffective.
Clinical Evidence
Clinical evidence based on 14 years of data, including a 2006 study in Chest of 220 patients. Primary endpoints included safety and complication rates. 55 filters were successfully retrieved after a mean of 51 days (range 6-352 days) without complication. Results demonstrate performance similar to predicate devices.
Technological Characteristics
316L stainless steel filter (9 legs) and forceps (8 arms). 7F sheath introducer. Polyethylene catheters. Apical fixation of wires. Non-clinical testing included simulated deployment, clot trapping, filter fracture, caval perforation/migration, thrombogenicity, and MRI compatibility.
Indications for Use
Indicated for patients requiring prevention of recurrent pulmonary embolism due to contraindication to anticoagulants, failure of anticoagulant therapy, or emergency treatment for massive pulmonary embolism.
Regulatory Classification
Identification
A cardiovascular intravascular filter is an implant that is placed in the inferior vena cava for the purpose of preventing pulmonary thromboemboli (blood clots generated in the lower limbs and broken loose into the blood stream) from flowing into the right side of the heart and the pulmonary circulation.
