BLOOD VESSEL OBTURATOR WITH TUBULAR COVER OF WOVEN FABRIC OR KNITTED FIBER

摘要

PURPOSE: To make fiber material in the form of woven or knitting fabric with an extremely high ratio to metal material be mounted firmly thus being able to be arranged in vessel tissues of a human body easily. CONSTITUTION: When catheter 100 is arranged in blood vessel 102 (for example, distal end 104 of catheter 100 is placed in aneurysm), a cannula comprising a coil 110 is fitted to a proximal end of catheter 100, and the coil 110 is moved from lumen of the cannula to lumen of catheter 100 by applying a force to a proximal end of the coil. Flexible pusher device 108 is used for pushing out coil 110 through catheter 100 to a desired coil releasing position. The position of coil 110 is observed due to the radioactive rayimpermeability of the metal coil. Once reaching the desired position, coil 110 is inserted solely from catheter lumen to a position 106 in blood vessel.
