Investigation: the following allegations have been investigated: vena cava (vc)/organ perforation, tilt, chest pain, dyspnea, variation in groins.Investigation is reopened due to additional information provided.The reported allegations have been further investigated based on the information provided to date.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 chest pain, dyspnea, and variation in groins are directly related to the filter and unable to identify a corresponding failure mode at this point in time.10 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 become available.This report is required by the fda under 21 cfr part 803.This report is based on unconfirmed information submitted by others.Neither the submission of this report nor any statement made in it is intended to be an admission that any cook device is defective or malfunctioned, that a death or serious injury occurred, or that any cook device caused or contributed to, or is likely to cause or contribute to a death or serious injury if a malfunction occurred.

Patient allegedly received an implant on (b)(6) 2008 via the right internal jugular vein due to venous thrombosis (vt) and pulmonary embolism (pe).Patient is alleging tilt and mesenteric perforation.The patient further alleges "persistent chest pain, shortness of breath, variation in right groins." (b)(6) 2020, report from ct: "there is an ivc filter which extends from the inferior aspect of l2 to the inferior aspect of l3.It is located within 2 cm of the lowest renal vein.This position is normal.There is slight left upper apex tilt of the filter.The apex touches the left margin of the inferior vena cava wall.The degree of tilt measures 14 degrees.There is perforation of the ivc filter legs with the wall of the inferior vena cava.The anterior strut extends beyond the caval wall by 4 mm.The lateral, right-sided strut extends beyond the wall by 4 mm: the posterior strut extends beyond the wall by 4 mm.The medial/left strut extends beyond the wall by 6 mm.There is no perforation to adjacent organs or vessels.No fracture or significant bending of the filter strut.No stenosis of the inferior vena cava.".
