be used to position the device also with respect of its rotation around its axis the structure of the anchoring portion 29 and of the deflecting portion 25 is essentially similar to the structure illustrated with reference to fig1 a the difference resides mainly in the design of the deflecting portion and in the provision of the markers 0057 fig2 a through 2c illustrates a carotid artery portion generally designated 36 in which the common carotid artery cca is designated 38 the internal carotid artery ica is designated 40 and the external carotid artery eca is designated 42 for placing the deflecting device 20 seen in fig1 conventional stent deployment equipment may be used which equipment typically comprises an expandable balloon 46 fitted at an end of an inflating tube 48 carried by a guide wire not seen however the device may also be self expandable as known per se and as readily understood by the skilled person the arrangement is such that by using suitable imaging equipment the assembly seen in fig2 a is inserted through the vasculator of an individual into the cca until the deflecting device 20 is positioned within the bifurcation zone 52 with the deflecting member 24 extending opposite inlet 54 of ica 40 in this position balloon 46 is inflated as shown in fig2 b whereby the anchoring walls 22 of deflecting device 20.
