Claims8
A blood flow transducer comprising a lumen section, said lumen section being split into a pair of arcuate lumen parts, an arcuate electromagnetic coil mounted in said lumen section, a pair of electrodes mounted in said lumen section, and mounting means for said lumen parts to enable selective rectilinear relative displacement therebetween, whereby said parts may be separated to provide a gap between adjacent edges thereof and moved towards each other to close said gap.
A blood flow transducer comprising a lumen section, said lumen section being split into a pair of arcuate lumen parts, each part having a pair of free ends, an arcuate electromagnetic coil mounted in said lumen section, a pair of electrodes mounted in said lumen section, and mounting means for said lumen parts to enable selective separation of both ends of one lumen part from both ends of the other lumen part, whereby said parts may be separated to provide a gap between adjacent ends thereof and moved towards each other to close said gap.
