Abstract:
Catheter ultrasound systems including a sheath, a handle (2), a sheath lumen, and an ultrasound catheter (196) disposed within the lumen of the sheath with ultrasound elements (220) capable of visualizing anatomical regions. The handle (2) allowing the ultrasound catheter (196) to rotate with respect to the sheath using a rotation adjustment knob within the handle or alternatively a separate manipulation handle attached to the proximal end of the ultrasound catheter (196). The sheath, ultrasound catheter (196), or both may also include one or more electrodes or other location sensor for both orienting the ultrasound element (220) as well as for diagnostic purposes.
Abstract:
The present invention is a catheter actuation handle (14) for deflecting a distal end (18) of a tubular catheter body (12), the handle including an auto-locking mechanism, (54). The handle comprises upper and lower grip portions (24a, 24b), an actuator (20), and an auto-locking mechanism, (54). The auto-locking mechanism (54) is adapted to hold a deflected distal end (18) of the catheter (10) in place without input from the operator. When the distal end (18) of the catheter (10) is deflected from its zero position, it typically will seek a return to its zero position, and as a result exerts a force on the actuator (20). The auto-locking mechanism (54) acts by providing a second force that resists this force from the distal end (18) and holds the distal end (18) in place. As a result, the operator does not need to maintain contact with the buttons (22a, 22b) to maintain the distal end (18) in a set position.
