A catheter tip (50, 170) is provided that is adapted for mating attachment to a catheter body (90, 300). In an embodiment, the catheter tip (50,170) comprises a transducer array (32, 60, 110, 210) in electrical communication with an interconnect (120, 220) and in a mechanical driven relationship with an actuator (80), also in the catheter tip (50, 170), via a drive shaft (38, 82). Oscillating back and forth motion of the transducer array (32, 60, 110, 210) provides ultrasonic imaging functionality that may include real time three-dimensional imaging. Other embodiments of the catheter tip (50, 170) and methods of fabrication also are provided.
An ultrasonic imaging catheter tip assembly comprising:
An ultrasonic imaging catheter tip comprising a cylindrical outer capsule comprising a cut-out section, a transducer array encapsulated in a rotatable cylinder comprising a solid material providing a desired ultrasound acoustical transmission, the rotatable cylinder positioned in the cut-out section and in driven relationship with an actuator positioned within the outer capsule, and an interconnect communicating with the transducer array and adapted to extend to or through a catheter body adapted to receive the catheter tip.
An ultrasonic imaging catheter tip comprising a cylindrical outer capsule comprising a cut-out section with a fluid-permeable membrane over the cut-out section, a transducer array encapsulated in a rotatable cylinder, the rotatable cylinder positioned in the cut-out section and in driven relationship with an actuator positioned within the outer capsule, and an interconnect communicating with the transducer array and adapted to extend to or through a catheter body adapted to receive the catheter tip.
An ultrasonic imaging catheter tip comprising a cylindrical outer capsule, a transducer array encapsulated in a rotatable cylinder, the rotatable cylinder comprising a gel material providing a desired acoustical transmission, the rotatable cylinder in driven relationship with an actuator positioned within the outer capsule, and an interconnect communicating with the transducer array and adapted to extend to or through a catheter body adapted to receive the catheter tip.
An ultrasound probe catheter tip comprising:
