Abstract: Provided is a method of forming a shaped structure. The method includes coupling a first section of a mold to a second section of the mold such that a mold cavity is defined, wherein a cross-sectional shape of the mold cavity corresponds to a cross-sectional shape of the shaped structure and wherein at least one of the first section of the mold and the second section of the mold comprise a soluble material; at least partially filling the mold cavity with a curable polymer; and curing the curable polymer in the mold cavity to make the shaped structure.

Abstract: Impellers made of composite materials with flow path cavities covered by an erosion resistant coating are manufactured by covering removable molds having shapes corresponding to a negative geometry of the flow path cavities, with the erosion resistant coating using plating or thermal spraying. After shaping and curing a composite material around the molds covered with the erosion resistant coating, the molds are removed, while the erosion resistant coating remains on the composite impeller.

Abstract: A catheter for ablating tissue is provided. The catheter comprises an elongated generally-tubular catheter body having proximal and distal ends. An electrode assembly is provided at the distal end of the catheter body. The electrode assembly including a porous electrode arrangement that is generally transverse to the catheter body. The porous electrode arrangement comprises one or more electrodes electrically connected to a suitable energy source and a porous sleeve mounted in surrounding relation to the one or more electrodes and defining an open space between the porous sleeve and the one more electrodes. One or more irrigation openings fluidly connect the open space to a lumen extending through the catheter through which fluid can pass. In use, fluid passes through the lumen in the catheter, through the one or more irrigation openings, into the open space and through the porous sleeve.
