A clot retrieval system comprises a clot retrieval device, a catheter 51, and a tubular shield element 61. The clot retrieval device comprises an elongate member 53 having a proximal end and a distal end, and a clot engaging element 54 at the distal end of the elongate member 53 the clot engaging element 54 having a collapsed delivery configuration and an expanded deployed configuration. The catheter is adapted for placement at a location at which a distal end of the catheter is proximal of the clot engaging element and the tubular shield element 61 extends over the elongate member 53 and is adapted for location between the distal end of the catheter and the proximal end of the clot engaging element 54. The tubular shield element 61 is movable relative to the elongate member 54 when the clot engaging element is in the expanded configuration in that the force that is applied on retraction of the elongate member is spread over the outer surface of the tubular shield element. The force that would usually be exerted on vessels on retrieval of the clot engaging element is spread by the shield element thus reducing the effects of abrasion.

A seal extending between adjacent slots of a gas turbine engine is disclosed. The seal comprises a plurality of generally planar members fixed together along a central axis. The outer member further comprises rounded ends that encompass the second and plurality of third generally planar members. The seal disclosed herein improves sealing capability by providing a more compliant seal over the prior art while reducing the mechanical loads experienced along the seal weld joint, thereby improving seal durability.

There is provided an organic light emitting display capable of improving the display quality of a low brightness region. The organic light emitting display includes pixels positioned at intersections of scan lines, emission control lines, and data lines, a converter for receiving data to generate brightness values, a timing controller for extracting emission time values and gamma values to correspond to the brightness values, an emission control line driver for supplying emission control signals to the emission control lines so that emission times of the pixels are controlled to correspond to the emission time values, and a gamma voltage generator for generating gamma voltages corresponding to the gamma values.

In an elastic wave device, an interdigital transducer (IDT) electrode is disposed on a piezoelectric substrate. In at least one of first and second electrode fingers of the IDT electrode, elongated sections with a widthwise dimension larger than that of a center of the first and second electrode fingers in a longitudinal direction are provided in at least one of a portion closer to a base end of the first or second electrode finger and a portion closer to a leading end of the first or second electrode finger than a central region of the first or second electrode finger. At least one of first and second busbars includes a plurality of openings provided separately from each other along the longitudinal direction of the first and second busbars.
