DEVICE FOR PROTECTING BIG-DIAMETER VESSELS WHEN MAKING MANIPULATIONS Russian patent published in 2007 - IPC A61F2/84 A61M25/00 A61F2/01 

FIELD: medicine; cardiac surgery.

SUBSTANCE: device can be used when doing low-invasion operations at vessels, which operations relate to rejection of intravenous filters together with thrombi and stints of vessels with bigger diameters without opening thorax under control of X-ray spectroscopy and echocardiography. Device for protection of big-diameter blood vessels during operation is made in from of two-channeled catheter onto which the soft container is placed for catching thrombi and fractures of torn-off tissue. Container has variable lateral size. Container has its wider side fastened to loop, which is connected with control handle by means of draught. Narrower side of container is connected with catheter. Loop is able of opening and to open container till complete overlap of gap in vessel. Openings are made in narrower part of container to keep blood current permanent. Working tool for controlling implant is disposed in one channel of catheter; working tool is capable of protrusion and independent manipulation. Filter of stint can be removed from big-diameter vessel safe and possible migration of torn-away fragment of vessel tissue or thrombus during manipulation is eliminated.

EFFECT: improved safe; higher reliability.
