Abstract
A tissue resecting device includes a handle coupled to an elongated sleeve assembly. The elongated sleeve assembly includes a windowed outer sleeve and an inner sleeve adapted to reciprocate and/or rotate relative to the window to resect tissue intruding into the window, where the resected tissue is captured in a channel in the sleeve assembly. One or more motors in the handle both move the inner sleeve relative to the window and operate a pump which causes a fluid to flow through the channel in the sleeve assembly to remove resected tissue therefrom.
Claims30
A tissue resecting device comprising:
- a handle coupled to an elongated sleeve assembly, wherein the elongated sleeve assembly includes a windowed outer sleeve and an inner sleeve adapted to move relative to the window to resect tissue intruding into the window, where the resected tissue is captured in a channel in the sleeve assembly;
- at least one motor in the handle configured to both move the inner sleeve relative to the window and to operate a pump which causes a fluid to flow through the channel in the sleeve assembly to remove resected tissue therefrom.
A tissue resecting system comprising:
- a handle coupled to an elongated sleeve assembly comprising a windowed outer sleeve and an inner sleeve adapted to move in a cycle to resect tissue interfacing with the window;
- a pump mechanism in or proximate the handle configured to provide a fluid flow through a channel in the sleeve assembly.
A tissue resecting system comprising:
- a handle coupled to a elongated outer sleeve with a closed distal end and a window that opens to an interior lumen;
- an inner sleeve adapted to longitudinally in said lumen between window open and window closed positions to thereby resect tissue in the window;
- and
- a resilient element disposed in distal end of said lumen adapted to interface with the distal end of the inner sleeve when in its distal-most position.
A tissue resecting system comprising:
- a handle coupled to a elongated outer sleeve with a closed distal end and having a window that opens to an interior lumen;
- and
- a motor-driven inner sleeve adapted to reciprocate longitudinally in a first distal direction across the window to resect tissue and in a second proximal direction to thereby open the window;
- wherein said inner sleeve carries an electrode for applying RF energy to tissue;
- and
- wherein a controller moves the inner sleeve in the first direction at a first speed and moves the inner sleeve in the second direction at a second different speed.
A tissue resecting system comprising:
- a handle coupled to an elongated outer sleeve with a closed distal end and having a window that opens to an interior lumen;
- and
- a motor-driven inner sleeve adapted to reciprocate longitudinally in a first distal direction to resect tissue which protrudes through the window and in a second proximal direction to thereby open the window;
- wherein said inner sleeve carries an electrode for applying RF energy to tissue;
- and
- wherein a controller modulates RF energy application and applies first RF energy parameters to the electrode when the inner sleeve moves in the first direction and applies second RF energy parameters to the electrode when the inner sleeve moves in the second direction.
