Abstract: A fluid handling system for applying a plurality of pulses of fluid shear stress to a fluid sample may comprise a first sample chamber; a second sample chamber; a plurality of conduits mounted between and in fluid communication with the first sample chamber and the second sample chamber; and a force delivery system mounted to the first sample chamber and configured to apply a force sufficient to push the fluid sample from the first sample chamber through each of the conduits at a substantially constant flow rate to the second sample chamber. The plurality of conduits may be arranged in series and separated by additional sample chambers or arranged such that the conduits are substantially parallel to one another. The force delivery system may be a gas delivery system or a linear drive assembly.

Abstract: A stent having an elongated tubular configuration consisting of at least one anchor section to inhibit migration. Said anchor section is fabricated by an expandable mesh of woven metallic or polymeric elements. The anchor is configured to minimize contact abrasion and irritation to the entrance of the lumen being stented, as well as to enervated tissue surrounding that entrance, as well as to better absorb forces and increase retention as the lumen is stretched.

Abstract: A stone capture device comprises a shaft with a deployable sweeping structure at its distal end. The shaft is adapted to be removably placed over and connected to a conventional ureteroscope. The combination of the stone capture device and ureteroscope can be introduced into the urinary tract to capture, fragment, and remove stones from the bladder and kidney.

Abstract: The vasoocclusive device for use in interventional therapy and vascular surgery adapted to be inserted into a portion of a vasculature, includes a vasoocclusive coil disposed about an inner reinforcement coil wherein said vasoocclusive coil is helically wound and the inner reinforcement coil forms a reverse helical winding opposite the vasoocclusive coil winding, thereby forming a biplex wound coil. The vasoocclusive device biplex winding provides improved mechanical properties to the device. An inner reinforcement stretch resistant member attached within the biplex windings limits coil stretchability.

Abstract: An endoscope includes an imaging device, a first polarizing filter disposed in front of the imaging device, a light source, and a second polarizing filter disposed in front of the light source.

Abstract: An endoscope includes an imaging device, a first polarizing filter disposed in front of the imaging device, a light source, and a second polarizing filter disposed in front of the light source. The planes of polarization of the first and second polarizing filters are at a substantially 90° angle.

Abstract: Occluding structures may be created within a body lumen by advancing a length of material distally through the body lumen. By drawing a distal location on the advanced length of material in a proximal direction, the material may be compacted into a structure which at least partially occludes the lumen. The occluding structure may be used to remove kidney stones from the ureter in conjunction with lithotripsy and irrigation.

Abstract: A luminal occlusion device comprises a tension member, an elongate shaft, and a flat film having an axial receptacle which is received over a distal portion of the tension member. The flat film has proximal and distal ends which are attached to the distal ends of the tension member and the elongate shaft, respectively. Thus, distal advancement of the tension member relative to the shaft will cause the flat film to assume a low profile configuration, while proximal retraction of the tension member relative to the elongate shaft will cause the flat film to assume a foreshortened, compacted configuration. The film usually includes one or more radioopaque markers which help shape the compacted film.
