For some time now we have been writing about the IVC filter, its role in helping to stop blood clots and the risks connect with device migration, or the failure of thin, metallic struts that can drift along the inferior vena cava and approach, or even penetrate vital organs, including the heart.
But what is the inferior vena cava, anyway? And why is it inferior?
In truth, there is no inferiority complex include. In fact, there are two venae cavae – two large veins that carry deoxygenated blood to the heart. The ‘inferior’ (lower) vena cava carries blood from the lower body to the heart, while the ‘superior’ (upper) vena cava carries blood from the upper half of the body.You can also visit http://www.bardfilterlawsuitcenter.com/bard-ivc-filter-lawsuit-lawyers.asp here to know more on ivc filter.
In medical terminology, one is known as ‘inferior,’ while the other is known as ‘superior.’ Both are vital to blood flow and ultimately, survival. However, the inferior vena cava continue the focus for blood clots that can form in the legs and travel up the inferior vena cava to the heart and lungs. Anti-coagulants (blood thinners) are most often used to thin the blood and help avert blood clots and stroke. However, patients who cannot tolerate blood thinners become prime candidates for the inferior vena cava filter – a device placed in the inferior vena cava and designed to entrap a wandering blood clot, and hold it in place so it doesn’t travel to the heart or lung.
However, as you have read before there have, and continue to be problems with IVC filters, which have been known to migrate from its initial insertion point and travel to the heart. Struts have been known to break off and undertake a similar migration to the heart, where the small, sharp struts have punctured the heart or become embedded in tissue, providing a grievous and ongoing health threat to the patient.
The Bard IVC filter has become the flashpoint for the issue. C.R. Bard is alleged to have known about difficulty with its original retrievable filter, but failed to undertake a recall and sat on the concern for some time before releasing what was purported to be an improvement over the original, problematic filter. However, critics have been suggesting that the Bard G2 IVC filter – the new and upgraded version – turned out to be not much better than the filter it was meant to replace. Many an IVC filter lawsuit has targeted C.R. Bard.
