Abstract: Methods and apparatus for treatment of patent foramen ovale (PFO) provide for applying energy to tissues adjacent the PFO with a catheter device to substantially close the PFO acutely. Apparatus generally includes a catheter device having at least one energy transmission member at or near its distal end configured to apply energy to PFO tissues to acutely, substantially close the PFO. Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like. Some embodiments of a catheter device further include one or more tissue apposition members near the distal end for helping bring PFO tissues together, such as a PFO covering member, a vacuum applying member and/or the like. PFO closure via energy-based approaches of the invention may help prevent stroke, treat migraine headache, and possibly treat or prevent other medical conditions.

Abstract: The application is directed to self-securing garments designed to be donned quickly and safely secured to the body in a matter of seconds. Described are garments having an opening in the back terminating at two opposite edges. Attached to the outside of the garment is at least one flexible elongated band at least partially comprised of a shape-memory material. The ends of the band are formed into dual, oppositely wound coils. To use, the wearer puts on the garment as usual and, grasping a flexible coil in each hand, pulls them so that they unwind and elongate while simultaneously wrapping them around the sides of the body. Upon release, the shape-memory material causes the coil to contract, thus embracing the body and holding the garment between the body and the uncoiled band. The garment can have one or more coiled bands, such as at the waist, chest, or neck, to secure the garment closely to the body quickly and without assistance.

Abstract: A forceps includes an end effector assembly. The end effector assembly includes first and second jaw members. At least one of the jaws is moveable with respect to the other between a spaced-apart position and at least one approximated position for grasping tissue therebetween. At least one of the jaw members is adapted to connect to a source of energy for sealing tissue disposed between the jaw members. A chamber is defined within and extends longitudinally along at least one of the jaw members. The chamber is configured to retain a fluid therein and includes a series of apertures disposed on a tissue-facing surface thereof such that, upon application of energy to the jaw member(s), fluid within the chamber is heated to thermally expand within the chamber and forcefully exit the apertures to divide tissue disposed between the jaw members.

Abstract: The present invention relates to a method for the realization of a structure for couches, beds, mattresses, chairs and the like. In particular, in accordance with a first embodiment, operations are foreseen that include the processing in machine tools of a single mono-block in such a way as to obtain a monolithic final structure. A superficial treatment of the structure thus obtained may be included. A second embodiment relates to the processing of one or more monolithic blocks to obtain many parts that are subsequently combinable with each other to obtain the final structure. In that case, a superficial treatment can be included to join the parts with each other and provide the mechanical features to the material, or, alternatively, the superficial treatment of the single parts and subsequent combination with each other can be performed. A shape-memory polymer composite material is of particular interest for the present application.

Abstract: An electromagnetic surgical ablation probe having a tunable helical antenna element is disclosed. The probe includes a coaxial feedline having an inner conductor coaxially disposed within a dielectric, and an outer conductor coaxially disposed around the dielectric. The inner conductor and dielectric extend distally beyond a distal end of the outer conductor. A helical antenna element is operably coupled to a distal end of the inner conductor. During use, the antenna may be tuned by changing at least one dimension of the helical antenna element. Embodiments are presented wherein a dimensions of the helical antenna element is changed by state change of a shape memory alloy, by a change in temperature, by activation of a piston by fluidic pressure, by linear motion of a conical tip, and by a manual screw-type adjustment.
