Axial retraction of the tip member moves the expandable portion from a closed position where the struts extend parallel with a centerline of the expandable portion to an opened position where the struts bow outwardly. An incising element is associated with at least one of the struts. The incising element extends parallel with the centerline when the expandable portion is in the closed position.

  • Patent number: 11083480
    Abstract: A gripping mechanism includes: two gripping pieces pivoted relative to each other about a pivot axis; a base supporting at least one of the gripping pieces; a pulley rotatably supported about a rotation axis parallel to the pivot axis; a wire wound around the pulley, causing tensile forces that move the rotation axis in one direction to act, and transmitting a pressing force; and a force-receiving portion receiving the pressing force. The pulley is disposed so that a resultant force of the tensile forces of the wire acting on the rotation axis generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be closed. The force-receiving portion is disposed so that the pressing force applied from the wire generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be opened.

  • Patent number: 11076841
    Abstract: A biopsy device has a flexible sheath having a terminus with a distal chamber. The distal chamber is configured with a forward facing cutting edge. The forwarding facing cutting edge has multiple movable blades, in which the movable blades are two counter rotating blades configured perpendicular or angular to a long axis of the distal chamber. Each counter rotating blade is configured to pivot from a separate axis. The biopsy has a manipulation end controllable by the user to plunge the forward facing cutting edge at a set depth or a depth selected by the user, and to engage a cutting action by the multiple movable blades at the set depth or the selected depth. The movement of the forwarding facing cutting edge enables the biopsy device to acquire a plurality of specimens for storage in the distal chamber.

  • Patent number: 11013907
    Abstract: Various surgical devices and methods are provided for monitoring and regulating tissue compression and cutting to improve tissue effect. In general, these devices include a handle portion, an elongate shaft, and an effector disposed at a distal end of the shaft and configured to engage tissue. In one embodiment, one or more sensors can be positioned at various locations on the device and can determine a force applied to tissue engaged by the end effector. When the force exceeds a threshold, a notification signal can be issued to a user. In another embodiment, a sensor can determine an amount of current moving between jaws of the end effector and a controller can slow a speed of the cutting element when the sensed current exceeds a threshold amount.
