    Abstract: Various methods and devices are provided for accessing a body cavity. In one embodiment, a surgical access device is provided and includes an elongate member having a proximal support member configured to rest against an external tissue surface, a flexible elongate central portion extending distally from the proximal support member and configured to extend through tissue, and an inflatable distal portion coupled to a distal end of the central portion. The distal portion is movable between an initial configuration, in which the distal portion is configured to be passed through an incision in tissue, and an inflated configuration in which the distal portion is expanded such that the central portion forms a working channel through the tissue for access to a body cavity. The distal portion can include an opening such that gas delivered to the distal portion can flow through the opening to insufflate a body cavity.

    Abstract: An end effector includes a first portion having a first specific acoustic impedance value, and a second portion having a second specific acoustic impedance value less than the first specific acoustic impedance value. The first portion includes a proximal end segment of the end effector and a distal end segment of the end effector, and the proximal end segment and the distal end segment are composed of a first material. The second portion includes an insert segment of the end effector composed of a second material. The insert segment is located between the proximal end segment and the distal end segment along the longitudinal axis of the end effector. The insert segment functions to bridge or fill the nodal energy gap. A surgical instrument includes a transducer configured to produce vibrations along a longitudinal axis as a predetermined frequency. An ultrasonic blade extends along the longitudinal axis coupled to the transducer. An insert segment or a pad is positioned adjacent to the blade such that it engages the blade when the surgical instrument is in a closed position and generates heat filling the nodal energy gap.
