    Abstract: A microfluidic device for separating target components from a source fluid includes one or more source channels connected to one or more collection channels by one or more transfer channels. The target components of the source fluid can be magnetic or bound to magnetic particles using a know binding agent. A source fluid containing magnetically bound target components can be pumped through the source channel of the microfluidic device. A magnetic field gradient can be applied to the source fluid in the source channel causing the magnetically bound target components to migrate through the transfer channel into the collection channel. The collection channel can include a collection fluid that is stagnant until a predefined volume of source fluid is processed or a predefined volume of target components accumulate in the collection channel, at which point collection fluid can be pumped into the collection channel to flush the target components out of the collection channel. The target components can be subsequently analyzed for detection and diagnosis.

    Abstract: A real time three dimensional ultrasound imaging probe apparatus is configured to be placed inside a body. The apparatus comprises an elongated body having proximal and distal ends with an ultrasonic transducer phased array connected to and positioned on the distal end of the elongated body. The ultrasonic transducer phased array is positioned to emit and receive ultrasonic energy for volumetric forward scanning from the distal end of the elongated body. The ultrasonic transducer phased array includes a plurality of sites occupied by ultrasonic transducer elements. At least one ultrasonic transducer element is absent from at least one of the sites, thereby defining an interstitial site. A tool is positioned at the interstitial site. In particular, the tool can be a fiber optic lead, a suction tool, a guide wire, an electrophysiological electrode, or an ablation electrode. Related systems are also discussed.

    Abstract: We have found that etching of a body that comprises exposed Si as well as a Ti-comprising metal layer (e.g., a patterned Ti/Pt layer) in an amine-based anisotropic etchant for Si (e.g., 100.degree. C. EDP) frequently results in undesirable changes in the Ti-comprising metal layer. We have also found that the changes can be substantially reduced or eliminated by electrolytic means, namely, by making the metal layer the anode in an electrolytic cell that contains the etchant.
