  • Medical device with articulating shaft
    Patent number: 9339286
    Abstract: A medical device (10) includes an articulating shaft (20, 20a, 20b, 20c, 20d, 20e, or 20f) with a pair of slat assemblies (31, 33). By moving an articulator (37), the slat assemblies (31, 33) are configured to concurrently push while the other pulls in order to bend the articulating shaft (20). The articulating shaft (20) includes a series of pivot members (26, 26a, 26b, 26c, 26d, 126e and 226e, or 126f and 226f). The pivot members (26) may include inner links (126e, 126f) and outer links (226e, 226f). A method for articulating a shaft of a medical device is also provided.

  • Medical device with articulating shaft
    Patent number: 7553275
    Abstract: A medical device includes an articulating shaft with a pair of slat assemblies. By moving an articulator, the slat assemblies are configured to concurrently push while the other pulls in order to bend the articulating shaft. The articulating shaft includes a series of alternating pins and pivot members. Each pin defines an aperture that collectively forms a passageway for receiving an actuator or a tube. The pair of slat assemblies extend generally parallel to each other on opposite sides of the pins. A method for articulating a shaft of a medical device is also provided.
