    Abstract: An ultrasound system has an ultrasound transducer having a transducer housing and a horn provided at the distal end of the transducer housing, an ultrasound transmission member, a sonic connector that is connected to the horn and the proximal end of the ultrasound transmission member, and a catheter knob having a proximal end that is coupled to the distal end of the transducer housing. The catheter knob has a proximal bore that houses the sonic connector. The system also includes a nesting piece that is retained inside the proximal bore of the catheter knob. The nesting piece can be moved from a first position where the sonic connector is received inside the nesting piece to a second position where the sonic connector is separated from the nesting piece when ultrasound energy is being propagated through the ultrasound transmission member.

    Abstract: Shape memory polymers featuring reversible actuation capability under ambient stimulus for integration with apparel. One approach is to use a multiblock polymer consisting of two (or potentially more) blocks in which the one block is the crystalline switching block with relatively low melting transitions, the other block has a higher thermal transition, and the two blocks are linked together by a linker molecule. Another approach is to use a graft copolymer having high and low melting transitions where the graft copolymer has a first polymer serving as the backbone and a second polymer being grafted to or from the backbone at certain graft locations. A further approach is to use latent crosslinking of a semicrystalline polymer with reactive groups placed on the backbone.

    Abstract: A surgical ablation system employing an ablation probe having a deployable ground plane is disclosed. The disclosed system includes a source of ablation energy and a source of electrosurgical energy, and a switching assembly configured to select between ablation and electrosurgical modes. The probe includes a cannula having a shaft slidably disposed therein. The shaft includes a deployable ground plane electrode assembly and a needle electrode disposed at distal end of the shaft. As the shaft is extended distally from the cannula, the ground plane electrode unfolds, and the needle electrode is exposed. Electrosurgical energy is applied to tissue via the needle electrode to facilitate the insertion thereof into tissue. Ablation energy is applied to tissue via the needle electrode to achieve the desired surgical outcome. The shaft, ground plane electrode and needle electrode are retracted into the cannula, and withdrawn from the surgical site.
