    Abstract: Surgical tools include an end effector mounted to an instrument shaft for articulation relative to the instrument shaft. A surgical tool includes an instrument shaft, an intermediate member pivotally coupled to the instrument shaft, an end effector and four tension members. The end effector includes an end effector base that is pivotally coupled to the intermediate member. The end effector base includes four attachment features. Each of the four tension members interfaces with an associated one of the four attachment features. The four tension members extend distally within a lumen of the instrument shaft and are arranged in diagonally opposed pairs.

    Abstract: A medical device can include a housing, a first seal structure, and a seal expander. The first seal structure can have a proximal end and a distal end, and a side wall surrounding and defining an interior chamber. A seal wall can be connected to the side wall and include an expandable opening. A seal expander can be coupled to the housing, and can be at least partially in the interior chamber of the first seal structure. The seal expander can include an expandable neck portion and a seal interface portion, the seal interface portion being near an intersection of the side wall and the seal wall.
