摘要： In one embodiment, an irrigated catheter ablation apparatus comprises an elongated body having a distal end, a proximal end, and at least one fluid lumen extending longitudinally therein; and a plurality of segmented ablation electrodes on a distal portion of the elongated body. The electrodes are spaced from the proximal end and from the distal end of the elongated body by electrically nonconductive segments. The electrodes are spaced from each other longitudinally by electrically nonconductive segments. For each electrode that is longitudinally disposed next to one of the nonconductive segments, an edge is formed between an electrode end of the electrode and a nonconductive segment end of the nonconductive segment. A plurality of elution holes are disposed adjacent to the edges. A plurality of ducts establish fluid communication between the elution holes and the fluid lumen.

摘要： An ablation apparatus comprises an ultrasonic transducer which includes a piezoelectric element having a cylindrical shape; a plurality of external electrodes disposed on the outer surface of the piezoelectric element; and at least one internal electrode disposed on the inner surface of the piezoelectric element. The at least one internal electrode provides corresponding internal electrode portions that are disposed opposite the external electrodes with respect to the piezoelectric element, the external electrodes and the at least one internal electrode to be energized to apply an electric field across the piezoelectric element. The ultrasonic ablation zones of the external electrodes are distributed in a staggered configuration so as to span one or more open arc segments around the longitudinal axis, and the ultrasound ablation zones of all external electrodes projected longitudinally onto any lateral plane which is perpendicular to the longitudinal axis span a substantially closed loop around the longitudinal axis.

摘要： A catheter for sensing electrical events about a selected annulus region of the heart and for treating tissue in the selected annulus region has a handle assembly, and a shaft having a proximal end coupled to the handle assembly. The catheter also has a mapping element provided adjacent its distal end, and an ablation element positioned spaced apart along the shaft from the mapping element. The mapping element is first positioned at the desired treatment location in the selected annulus region and the desired treatment location is mapped. The ablation element is then positioned at the desired treatment location by moving the mapping element away from the desired treatment location, and the desired treatment location is ablated.

摘要： A lead includes an elongated body and an anchor segment disposed between the distal end of the body and electrodes on a distal portion of the body. The anchor segment has lobes which are separated by slits and movable between a collapsed position and an expanded position. A positioning mechanism is disposed inside the hollow interior of the body and at least partially within the anchor segment. The positioning mechanism has a distal positioning portion attached to the distal end of the body and a proximal positioning portion. A control member is connected with the proximal positioning portion to control the positioning mechanism to pull the distal end toward the proximal end so as to move the lobes from the collapsed position to the expanded position and to push the distal end away from the proximal end so as to move the lobes from the expanded to the collapsed position.

摘要： High quality flexible optical mirrors (in a single or multi-layer implementation) are fabricated from polymer matrix composite material(s) by replication, cast-spinning, and 3-D printing processes. These mirrors are suited as controllable mirrors for different applications including telescope mirrors. The mirrors made from “smart” materials (carbon nanotubes in epoxy) attain controlled properties that may be changed by application of external stimuli, including stress, temperature, moisture, electric and magnetic fields, as well as electromagnetic fields. When formed with non-ferrous metal particles embedded in epoxy, the mirrors are suited for cryogenic operations. The mirrors formed with the ferromagnetic/epoxy material can be deformed and steered by magnetic or electromagnetic fields.
