摘要：
Disclosed is a medical device that includes a phased array ultrasound transducer. The transducer includes a number of transducer elements that are electrically coupled to corresponding electrical conductors. In one embodiment, the conductors are included in a flex circuit and engage corresponding transducer elements though a conductive surface formed on outwardly extending ribs of a frame that holds the ultrasound array. In one embodiment, the phased array is forward facing in the medical device and has an element pitch of 0.75 lambda or less and more preferably 0.6 lambda or less. In one embodiment, the transducer is rotatable over an angle of +/−90 degrees to provide a 360 degree view of tissue surrounding the distal end of the device.
