Abstract
A tissue-resecting probe includes an elongated outer sleeve extending about an axis to a distal housing having a first window for receiving tissue. An edge of the first window has a dielectric surface. A rotatable inner sleeve has a second window, and at least a portion of an edge of the second window provides a first polarity electrode. Rotation of the inner sleeve within the outer sleeve moves the probe between window-open and window-closed configurations to resect tissue.
Claims18
A tissue-resecting probe comprising:
- an elongated outer sleeve extending about an axis to a distal housing having a first window for receiving tissue, wherein an edge of the first window has a dielectric surface;
- and
- a rotatable inner sleeve having a second window wherein the inner sleeve carries a first polarity electrode and wherein rotation of the inner sleeve within the outer sleeve moves the probe between window-open and window-closed configurations to resect tissue;
- a motor for rotating the inner sleeve;
- a controller for controlling the motor, wherein the controller is configured to de-activate the first electrodes in response to a signal of an operational parameter of the motor.
The tissue-resecting probe of claim wherein an edge of the second window comprises the first polarity electrode.
A tissue-resecting probe comprising:
- an elongated probe comprising a windowed outer sleeve and cooperating windowed inner sleeve that is rotatable to resect tissue, wherein an edge of the inner sleeve window comprises a first polarity electrode and a portion of the outer sleeve comprises a second polarity electrode;
- a motor for rotating the inner sleeve;
- and
- a controller and electrical source operatively connected to the first and second electrodes, wherein the controller is configured to de-activate the first and second electrodes in response to a signal of an operational parameter of the motor.
A tissue-resecting probe comprising:
- an elongated probe comprising a windowed outer sleeve and cooperating windowed inner sleeve that is rotatable to resect tissue, wherein an edge of the inner sleeve window comprises a first polarity electrode and a portion of the outer sleeve comprises a second polarity electrode;
- a motor for moving the inner sleeve;
- and
- a controller and electrical source operatively connected to the motor and to the first and second electrodes, wherein the controller is configured to receive stop rotation of the motor and the inner sleeve relative to the outer sleeve in at least a first position.
