G4: 510(k) - k211875.Additional information: investigation.Investigation is reopened due to additional information provided.The reported allegations have been further investigated based on the information provided to date.The following allegations have been investigated: fracture, aorta/vena cava perforation, migration, pain, physical limitations.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.Filter or filter fragment migration and (or) embolization (e.G., movement to the heart or lungs) has been reported.Filter or filter fragment movement has occurred in both the cranial and caudal direction and may be either symptomatic or asymptomatic.Potential causes may include filter placement in ivcs with diameters smaller or larger than those specified in these instructions for use; improper deployment; deployment into thrombus; dislodgement due to large thrombus burdens; 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: filter migration, trauma to adjacent structures.Unknown if the reported pain, physical limitations is directly related to the filter and unable to identify a corresponding failure mode at this point in time.20 devices in lot.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.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) 2019 due to right lower extremity deep vein thrombosis (dvt) and contraindication to anticoagulation.Patient is alleging migration, vena cava perforation, and fracture.The patient further alleges "pain in right side," as well as physical limitations.Report from ct (computed tomography): "ln!rarenal ivc filter; the medial tine abuts the right aortic wall, unchanged." report from ct: "redemonstration of infrarenal ivc filter with medial tine projecting into the medial wall of the abdominal aorta (series 5, image 34 and series 6, image 56).Mild calcified atherosclerotic disease of the abdominal aorta and its branch vessels." report from ct: "ivc filter with likely extension beyond the lumen and at least one of which abuts/within the aortic wall, stable.Atherosclerotic disease." medical opinion referencing ct report from (b)(6) 2021: migration of limb is noted in right lateral aspect abutting the gonadal vein.Migration of limb noted in left lateral aspect abutting the aorta." medical opinion referencing ct report from (b)(6) 2021: "ivc stem is seen above the level of renal vein with a linear fracture.(image 1).Migration of limb is noted in right lateral aspect abutting the gonadal vein.(image 2).Migration of limb noted in left lateral aspect abutting the aorta.(image 3)".
