Abstract: A prerotation basin for use in a sump pit or wet well includes a basin body having an upstanding exterior wall, an interior concavity for placement of a pump inlet therein, and a fluid entry channel formed in the basin body defined by a discontinuity in the upstanding exterior wall, where the fluid entry channel has a channel floor, the threshold of which is at an elevation that is equal to or lower than the elevation of the bottom surface of the interior concavity. The prerotation basin thereby provides a channel floor that slopes upwardly toward the bottom surface of the interior concavity to provide better solids entrainment in fluid being processed from the sump pit or wet well, and to provide self-flushing of the basin.

Abstract: Techniques for creating a mesoporous surface for enhanced bone integration are provided. An example of a method for generating a mesoporous surface on a substrate includes depositing a layer of titanium on an area of the substrate to generate a nano-textured surface, and anodizing the layer of titanium on the area of the substrate to generate the mesoporous surface. The method may also include incorporating pharmaceutical, biological, or molecular additives into the mesoporous surface intended to further enhance performance of the substrate via enhanced osseoconduction, osseoinduction, or antimicrobial/anti-infective properties.

Abstract: Methods and apparatus are disclosed for inserting flexible, multi-lumen catheters into blood vessels, and in particular, for inserting flexible, split-tip catheters into blood vessels. The invention accomplishes these objects by temporarily stiffening each catheter lumen and tip independently through use of intra-catheter stiffener elements disposed within the catheter lumens. This provides means for advancing the catheter/stiffeners assembly through a subcutaneous tunnel, and over a plurality of guidewires until a distal tip of the catheter is at a desired position within the vessel. The intra-catheter stiffener elements are sufficiently stiffening to allow advancing the catheter over guidewires, but sufficiently flexible to allow bending and looping of the catheter for proper placement within the vessel.

In one aspect of the invention, the manufacturing methods can include the steps of: providing a catheter body having at least a first and a second internal lumen extending longitudinally through the catheter body; removing a distal portion of the catheter body to form a first distal tip segment such that the first lumen extends longitudinally within this tip segment beyond the second lumen; and joining a second lumen tip segment to the catheter body in communication with the second lumen. The second tip segment can be joined to the catheter body such that it is at least partially separated from the first tip segment and, in some embodiments, preferably diverges at an angle relative to the first tip segment.
