Abstract: In an example, a fluid collection device includes a fluid impermeable barrier that at least partially defines a chamber. The fluid impermeable barrier also defines an opening extending therethrough. The opening is configured to be positioned adjacent to a female urethra or have a male urethra positioned therethrough. The fluid collection device also includes a conduit at least partially disposed in the chamber. The conduit defines at least one aperture that allows an interior of the conduit to be in fluid communication with the chamber. The fluid collection device further includes a valve. The valve includes a first aperture coupled to the conduit and a second aperture that is fluid couplable to at least one of an air source, a vacuum source, or a fluid storage container. The valve is configured to control fluid flow through the conduit responsive to direction from a user.

Abstract: Devices and methods for vascular navigation, assessment, treatment and/or diagnosis are disclosed. The system generally comprises an elongate body sized for introduction and translation through a catheter lumen. One or more openings may be located at or in proximity to a distal end of the elongate body and a sensor is positioned at or in proximity to the distal end. The sensor is configured to measure at least one parameter of a mixture of a first fluid and a second fluid after the first fluid is emitted from the openings and into the second fluid when the distal end is advanced beyond a distal opening of the catheter lumen. A controller in communication with the sensor is configured to receive a signal indicative of the at least one parameter and is further configured to obtain a position of the sensor within a body of a subject based upon the signal.

Abstract: We describe the novel use of a sugar-containing hydrogels as very highly porous, aqueous support material for the immobilization of oligonucleotides, peptides, proteins, antigens, antibodies, polysaccharides, and other biomolecules for sensor applications. The unusually large sizes of the interconnected pores allow large target molecules to pass rapidly into and through the gel and bind to immobilized biomolecules. An additional advantage of the sugar-containing hydrogels are their extremely low non-specific absorption of labeled target molecules, providing low background levels. State-of-the-art hydrogel materials do not have this type of homogeneous interconnected macroporosity, thus large target molecules cannot readily diffuse through them. In addition, they nearly always experience non-specific (background) absorption of labeled target molecules, limiting their usefulness in sensor applications.

Abstract: The wall thickness of lipid microtubules are controlled by selecting a methanol/water system and determining the required amount of a lipid to form the desired wall thickness. The lipid is dissolved in a small portion of the heated methanol and that clear solution is added to the remaining amount of the heated methanol/water system. By slowly cooling the solution, microtubules are formed which have the desired wall thickness. Preferred microtubules have a wall thickness of just 2 bilayers and they are robust so they can be further coated. They can be made with a large aspect ratio and with lengths of greater than 250 microns. The process permits production of microtubules in very high yields.

Abstract: Lipid microtubules having a controlled bilayer structure and high aspect io are formed in a methanol/ethanol/water solvent system. The lipid microtubules may then be catalyzed (e.g., with a palladium/tin catalyst) in an acidified catalytic bath having no more than about 30 g of catalytic salts. These catalyzed microtubules are then metallized using a diluted plating bath with replenishment of the plating bath as needed to obtain the desired metallization thickness.
