Abstract: A tissue removal device may include a handle. The device may include a sheath coupled to the handle. A first portion of the sheath may be within the handle. A second portion of the sheath may protrude from the handle. The sheath may include a passage. The device may include an end effector coupled to an end of the sheath. The device may include a drive member coupled to the handle and to the end effector. The drive member may extend through the passage of the sheath to the end effector. Actuation of the handle may move the end effector between an open state, for receiving material, and a closed state, for holding onto material, by causing relative movement between the drive member and the sheath. Further actuation of the handle may move the end effector relative to the handle while the end effector remains in the closed state.

Abstract: A handle assembly includes a drive wire coupled to an expandable end effector, the wire having a diameter of no more than 3 French and a handle cannula receiving the wire therethrough, rotation of the handle cannula transferring torque to rotate the wire. The assembly also includes a shaft receiving the handle cannula, rotation of the shaft transferring torque to rotate the handle cannula. The assembly further includes an actuation assembly receiving the shaft, the actuation assembly coupled to a sheath sized to receive the wire and end effector therethrough, the actuation assembly moveable between a proximal configuration in which the sheath is moved proximally to expand the end effector and a distal configuration in which the sheath is moved distally to retract the end effector, the actuation assembly including a rotation mechanism transferring torque to the shaft to rotate the shaft.
