Abstract: A stent delivery system can facilitate positioning of a stent within a first vessel. The system can include an elongate member, an expandable stent coupled to the elongate member, and an imaging mechanism, such as an ultrasonic probe. The imaging mechanism can be positioned distal or proximal relative to the stent or adjacent to an aperture in the stent, such that the imaging mechanism can facilitate positioning of the stent within the first vessel such that flow into an orifice of a second vessel is not blocked by the stent.

Abstract: A fenestrated endograft having an expandable stent frame and a lumen is described herein. The stent frame has a proximal end portion, a distal end portion, and a central portion. The central portion may include a fabric that has an aperture partially surrounded by part of the expandable stent frame. The lumen extends through the proximal end portion, the central portion, and the distal end portion. The stent frame is radially expandable from a collapsed configuration to an expanded configuration. The central portion is coupled to a fabric, which extends about a perimeter of the central portion. The fabric has an aperture with a cross-sectional dimension that is substantially equal to a cross-sectional dimension of an outer cross-sectional dimension of the distal end portion. The central portion has a curved elongate member, which includes a curved segment extending around at least one-fourth of a perimeter of the aperture.

Abstract: A basket that is used in a pool cleaning system includes a flap that is biased closed and is opened against the bias by water flowing into the basket. When a pump drawing water out of a pool moves water through the basket, debris in the water is trapped in the basket. However, when the pump is shut off, any back flow of water associated with the pump shut off will not cause debris to move out of the basket because the flap will be shut by the bias and the backward movement of water.

Abstract: A method for enhancing the optical performance of a reflective spatial light modulator by micro-planarizing surfaces within the SLM, such as the reflective surface of each pixel, by gas-cluster-ion-beam bombardment.

Abstract: A laminate of plaster reinforced with a monofilament, continuous strand, glass fibre, preferably in the form of a mat. The laminate can be made flexible by subjecting it to stress, such as by rolling it to cause flexion.
