Abstract
Apparatus for intravascular ultrasonic imaging comprises a catheter having an ultrasonic transducer array fabricated at least in part from an electrostrictive material, wherein the electrostrictive material is non-polymeric.
Claims21
An apparatus for intravascular ultrasonic imaging, the apparatus comprising:
- a catheter having an ultrasonic transducer array fabricated at least in part from non-polymeric electrostrictive material;
- and
- a high permitivity ceramic member or layer that couples a common radiofrequency source to elements of the array.
A method of manufacturing a catheter for intravascular ultrasonic imaging having an ultrasonic transducer array fabricated at least in part from a non-polymeric, electrostrictive material, the method comprising:
- fabricating the transducer in-the-flat;
- the transducer array comprising a high permitivity ceramic member or layer that couples a common radiofrequency source to elements of the array;
- and
- reconfiguring the array into a substantially cylindrical configuration.
