  • Publication number: 20220323223
    Abstract: According to a general aspect, an insertion device can include an elongate barrel having an opening defined in a distal end; a lumen defined within the elongate barrel, the lumen being accessible through the opening; and an obturator disposed within the lumen of the elongate barrel. The obturator can be movable within the lumen between a proximal position in the elongate barrel and a distal position in the elongate barrel. The obturator, in its distal position in the elongate barrel, can be configured to receive a needle via the opening. The obturator, in its proximal position in the elongate barrel, can be configured to secure the needle within the elongate barrel.

  • Publication number: 20220322913
    Abstract: A medical device includes a sheath extending longitudinally from a proximal end to a distal end and a handle coupled to the proximal end of the sheath. The handle includes a deflection lever coupled thereto. The deflection lever is rotatable proximally and distally along the handle to deflect a distal end of the shaft to which it is operably coupled and a locking mechanism movable between an locked configuration in which the locking mechanism engages an engagement feature on the outer surface of the handle, preventing the deflection lever from rotating and locking the distal end of the shaft in a desired position, and an unlocked configuration in which the locking mechanism releases the engagement feature to allow rotation of the deflection lever and deflection of the distal end of the shaft.

  • Publication number: 20190388074
    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.
