The previous medwatch report was submitted by william cook europe under manufacturer report reference# 3002808486-2020-00451.Additional information provided determined that this device was manufactured by cook inc.With the submission of this initial medwatch report, cook inc.Informs that all future submissions regarding this complaint will be handled under the manufacturer report reference #.Initial reporter occupation: non-healthcare professional.Investigation: the following allegations have been investigated: fracture, vena cava perforation, tilt, anxiety, pain.Investigation is reopened due to additional information provided.The reported allegations have been further investigated based on the information provided to date.Filter fracture has been reported and may be either symptomatic or asymptomatic.Fracture of a filter leg may be due to repetitive motion on a filter leg in an unusual, stressed position, such as a filter leg penetrating/perforating the ivc; or a filter leg being caught in a side branch (e.G., a renal vein).Other potential causes of filter fracture may include excessive force or manipulations near an implanted filter (e.G., a surgical or endovascular procedure in the vicinity of a filter).Retrieval of a fractured filter or filter fragments (including embolized fragments) using endovascular techniques has been reported.Potential adverse events that may occur include, but are not limited to, the following: filter fracture, filter or filter fragment embolization, trauma to adjacent structures.Filter interacts with ivc wall, e.G.Penetration/perforation/embedment.This may be either symptomatic or asymptomatic.Potential causes may include improper deployment; and (or) excessive force or manipulations near an in-situ filter (e.G., a surgical or endovascular procedure in the vicinity of a filter).Potential adverse events that may occur include, but are not limited to, the following: trauma to adjacent structures, vascular trauma, vena cava perforation, vena cava penetration.Filter tilt has been reported.Potential causes may include filter placement in ivcs with diameters larger than those specified in these instructions for use; improper deployment; manipulations near an implanted filter (e.G., a surgical or endovascular procedure in the vicinity of a filter); and (or) a failed retrieval attempt.Excessive filter tilt may contribute to difficult or failed retrieval; vena cava wall penetration/perforation; and (or) result in loss of filter efficiency.Potential adverse events that may occur include, but are not limited to, the following: unacceptable filter tilt.Unknown if the reported anxiety, pain are directly related to the filter and unable to identify a corresponding failure mode at this point in time.(b)(4) devices in lot.No relevant notes on work order.The product is manufactured and inspected according to specifications.No evidence to suggest that this device was not manufactured according to specifications and nothing indicates that the filter did not perform as intended, e.G.Intended for the prevention of recurrent pulmonary embolism (pe) via placement in the vena cava.Cook will reopen its investigation if further information is received warranting supplementation in accordance with 21 c.F.R.803.56.This report includes information known at this time.A follow-up medwatch report will be submitted if additional relevant information becomes available.

Patient allegedly received an implant on (b)(6) 2013 via right femoral vein due to conjunct with/or orthopedic proc.The patient alleges tilt and fracture.The patient further alleges pain on left side, anxiety.On (b)(6) 2019, per a report from computed tomography; ¿findings: inferior vena cava: interval placement of a greenfield filter into the infrarenal inferior vena cava.The superior margin of the filter is immediately below the level of the confluence of the right and left renal veins with the inferior vena cava.The filter is oriented from slightly inferior lateral to superomedial the superior tip of the filter abutting the left lateral wall of the ivc.The inferior prongs of the filter protrude beyond the wall of the inferior vena cava as follows: right anterior strut extends 5.5mm beyond the inferior vena cava into the fat and does not contact any organs.Left anterior strut protrudes 4.6mm beyond the wall of the inferior vena cava into the retroperitoneal fat and does not contact the abdominal aorta or other organs.Right posterior strut extends 4.7mm beyond the wall of the inferior vena cava into the retroperitoneal fat and does not contact the vertebral body or any organs.Left posterior strut extends 4.3mm beyond the wall of the inferior vena cava and abuts the wall of the abdominal aorta.No retroperitoneal mass or hemorrhage.¿.
