Blank fields on this form indicate the information is unknown, unavailable, or unchanged.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.New pe as a reported complication, is a known risk in relation to filter implant and is well documented in the clinical literature and in clinical practice guidelines.This is supported by the clinical evidence report established to assess available clinical data to identify and evaluate the clinical safety and performance of the cook vena cava filters.Potential adverse events that may occur include, but are not limited to, the following: pulmonary embolism.Ivc occlusion/ thrombosis, new dvt, ivc stenosis as a reported complication, is a known risk in relation to filter implant and is well documented in the clinical literature and in clinical practice guidelines.This is supported by the clinical evidence report established to assess available clinical data to identify and evaluate the clinical safety and performance of the cook vena cava filters.Potential adverse events that may occur include, but are not limited to, the following: vena cava occlusion or thrombosis, vena cava stenosis, deep vein thrombosis.Physician practice guidelines and published guidance from regulatory agencies recommend that patients with indwelling filters undergo routine follow-up.The risks/benefits of filter retrieval should be considered for each patient during follow-up.Once protection from pe is no longer necessary, filter retrieval should be considered.Filter retrieval should be attempted when feasible and clinically indicated.Filter retrieval is a patient-specific, clinically complex decision; the decision to remove a filter should be based on each patient¿s individual risk/benefit profile (e.G., a patient¿s continued need for protection from pe compared to their experience with and (or) ongoing risk of experiencing filter-related complications).For all retrievable ivc filters, retrieval becomes more challenging with time, and this is commonly due to encapsulation of the filter legs or hook (in a tilted filter) by tissue ingrowth.The filter is designed to be retrieved with the günther tulip vena cava filter retrieval set.It may also be retrieved with the cloversnare® vascular retriever.Cook has not performed testing to evaluate the safety or effectiveness of filter retrieval using other retrieval systems or techniques.The published clinical literature includes descriptions of alternative techniques for filter retrieval; use of these techniques varies according to physician experience, patient anatomy, and filter position.The safety or effectiveness of these alternative retrieval techniques has not been established.Specific for ¿embedded¿ a filter that is embedded in the wall of the ivc may be difficult to retrieve.For all retrievable ivc filters, retrieval becomes more challenging with time, and this is commonly due to encapsulation of the filter legs or hook (in a tilted filter) by tissue ingrowth.Unknown if the reported thrombectomy, balloon angioplasty, pain, complications, femoral vein catheterization, and thrombolytic therapy are directly related to the filter and unable to identify a corresponding failure mode at this point in time.20 devices in lot.No relevant notes on work order.The product is manufactured and inspected according to specifications.The following allegations have been investigated: pulmonary embolism, deep vein thrombosis (dvt), thrombus, inability to retrieve, thrombectomy, balloon angioplasty, pain, complications, femoral vein catheterization, thrombolytic therapy.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.The following fields were updated per additional information received: a2, a4, b1, b5, b6, b7, d1, d4, h4, h6.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 via the right common femoral vein due to deep venous thrombosis and pulmonary embolism.Patient is alleging inability to retrieve, thrombus, deep venous thrombosis, thrombectomy and balloon angioplasty.Patient further alleges pain, complications, femoral vein catheterization, thrombolytic therapy, pulmonary embolism.Report from computerized tomography (ct): "infrarenal ivc filter in place, with likely acute thrombus within the ivc, iliac veins, and femoral veins." report from venogram: "chronic and acute right femoral vein dvt, which ws treated with balloon angioplasty plus mechanical thrombectomy plus thrombolytic therapy using tpa infustion.The patient also had a thrombus in the ivc filter with significant thrombus burden, which ws treated with mechanincal thrombectomy using agiojet mechanical thrombectomy device.
