Indications for Use
The ALN Optional Vena Cava Filter and the ALN Optional Vena Cava Filter with Hook 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 and the ALN Optional Vena Cava Filter with Hook may be retrieved according to the instructions supplied in the Instruction For Use of the ALN Extraction Kit. The ALN Optional Vena Cava Filter with Hook may be retrieved with a standard GooseNeck Snare according to the instructions supplied in the Instruction For Use of this medical device. Extraction kit: The ALN Optional Vena Cava Filter Extraction Kit has been designed for the removal of an implanted ALN Optional Vena Cava Filter or ALN Optional Vena Cava Filter with Hook 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 316L stainless steel vena cava filter (9 legs, optional retrieval hook) and extraction kit (8-arm 316L stainless steel forceps). Filter delivered via 7F sheath (jugular, brachial, or femoral approach) to capture free thrombus in vena cava. Extraction performed via jugular approach using provided forceps or standard Gooseneck snare. Used by physicians in clinical settings. Filter traps emboli to prevent pulmonary complications; retrieval allows removal once patient no longer requires protection, reducing long-term risks associated with permanent implants.
Clinical Evidence
Clinical performance supported by 14 years of data and literature review. A study of 220 patients receiving the filter for VTE prevention showed low complication rates. 55 filters were successfully retrieved after a mean of 51 days (range 6-352 days) without complication. Clinical performance is consistent with predicate devices.
Technological Characteristics
316L stainless steel filter (9 wires); 8-arm stainless steel forceps. 7F filter introducer; 9F extraction kit introducer. PE catheters. Features include apical wire fixation, optional retrieval hook, 28-32mm base diameter, 55mm height. Non-clinical testing confirmed MRI compatibility.
Indications for Use
Indicated for prevention of recurrent pulmonary embolism in patients with contraindications to anticoagulants, failure of anticoagulant therapy, or emergency treatment for massive pulmonary embolism. Applicable to patients requiring vena cava filter placement and subsequent retrieval when no longer needed.
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.
