Device with a locating member for removably implanting a blood filter in a vein of the human body |
摘要 |
This device comprises an elastic guide wire onto which is fitted a semi-rigid tubular mandrel which is in turn fitted into a thin-walled tubular sheath. A catheter in the form of an easily divisible flexible tube has a distal end that permanently holds a blood filter. The catheter's proximal end receives a locating member that can be confined under the skin of a patient to insure that no infection develops. After the filter is temporarily implanted, a removable strengthening cable can be inserted into the catheter to advance the filter along the sheath to a chosen position in a vein, in particular the inferior vena cava, of the patient. The locating member makes it easy to remove the filter whenever the risk of pulmonary embolism is no longer present.
