Safety mechanism and methods to prevent rotating imaging device from exiting a catheter |
摘要 |
The invention provides exemplary systems and methods to prevent rotation of an imaging device if the imaging device is advanced beyond a distal end of a catheter. In one exemplary embodiment, a catheter is provided which comprises a catheter body having a proximal end, a distal end and a lumen which terminates in an exit port at the distal end. The lumen is configured to receive a rotatable imaging device having an ultrasonic imaging element. An ultrasonically recognizable pattern is disposed proximally to or at the exit port. The pattern is adapted to reflect a signal from the imaging element to produce a unique detectable image which in turn is employed to stop rotation of the imaging device.
