Embodiment Construction
[0029] figure 1 Shown is an embolic protection device, including a pushing guide wire 10 , a filter 20 , and a catheter 30 . Filter 20 is shown in an expanded state external to catheter 30 . The filter 20 has a screen 21 for blocking emboli. The pushing guide wire is connected with the filter, and there is a cannula at the connection, which is divided into a distal cannula 221 and a proximal cannula 222 . The cannula can be fixedly connected to the pushing guide wire 10, and the way of fixed connection can include one or a combination of welding, crimping, bonding and the like. The cannula can also be slipped over the push wire over the guide wire. One embodiment is to fix limit devices 501 and 502 on the pushing guide wire. When the filter is slidably connected to the guide wire, the limit devices are used to limit the sliding range of the filter to a certain area. The distal end of the catheter 30 has a visualized marker ring 31 for indicating the position of the cathete...
