  • Patent number: 11890027
    Abstract: An endoscopic grasping device for use during an endoscopic procedure. The device includes at least a fork operably connected to a pair of jaws pivotally mounted about a pivot point to the fork. A pusher is disposed within the fork and operably connected to a drive wire and a pair of arms. Each arm is attached to a respective jaw and configured to move that jaw upon a movement of the pusher in a distal direction or proximal direction resulting in the pair of jaws being in a closed position and a open position. Each jaw includes a plurality of teeth extending therefrom and towards the opposite jaw. One or more of the teeth are backwards curved and angled in a proximal direction from the jaw to improve a grasping, cutting, and handling feature of the teeth.

  • Publication number: 20230363764
    Abstract: An endoscopic device, includes a clip assembly and a driving assembly. The clip assembly includes a first jaw, a second jaw, a pivot, a housing having an internal channel, and a release portion connecting to the first and second jaws. At least a portion of the first and second jaws is disposed within the internal channel, the first and second jaws selectively move along with the internal channel. The driving assembly includes an outer sheath, an inner tube, movably disposed within the outer sheath, and a driver, movably disposed within the inner tube, and removably received within the release portion. The driver is unbrokenly released from the release portion by a predetermined pull force. The housing and the outer sheath form a releasable handshake engagement. The inner tube extending into the housing prevents the handshake engagement from disengaging.

  • Publication number: 20210298777
    Abstract: An endoscopic device includes a base, one or more end effectors, and an actuating assembly. The base includes a cylindrical shaft will a hollow interior. The end effectors are connected to the distal portion of the base such that the end effectors are movable between open and closed positions. The actuating assembly moves the end effectors between the open and closed position. The actuating assembly includes a driver that has at least one stopper feature extending radially from the driver shaft. The driver of the actuating assembly is at least partially disposed within the hollow interior of the base such that the stopper feature is movable in an opening of the base. The stopper feature engages a distal edge of the opening to prevent movement of the driver in a distal direction relative to the base and engages a proximal edge of the opening to prevent movement of the driver in a proximal direction relative to the base.

  • Publication number: 20180228503
    Abstract: A medical device for performing an endoscopic procedure through an endoscope is provided. The device includes an elongated catheter having a first lumen and a second lumen; a needle system for injecting a target tissue within a body; and a base disposed at a proximal end of the catheter. The actuator tube is inserted through the base and the first lumen. A needle housing member is positioned between the needle and the first lumen when the needle is in a stored position. The needle housing member has a predetermined length so that the needle is disposed within the needle housing member when the needle is at the stored position. The needle housing member has a continuous inner surface and prevents the needle from penetrating the first lumen. The needle includes a tip, deflected towards a center axis of the needle. The first and second lumens have different deflected forces.
