摘要： Disclosed is a user terminal for wireless communication with a remote access point, the user terminal comprising: a mapping module adapted to map one or more input data bits to an uplink symbol; a delay module adapted to apply a delay to the uplink symbol; a transmit module adapted to modulate the delayed symbol into a frequency channel; and a directional antenna oriented along a dominant path to the access point, the antenna being adapted to transmit the modulated symbol to the access point, wherein the delay is chosen such that the transmitted symbol arrives at the access point simultaneously with a further symbol modulated into the frequency channel and transmitted by a further user terminal.

摘要： A catheter used for treatment of complex vasculature, such as a bifurcated aneurysm, is provided with an inflatable balloon at a distal portion thereof. The shape, location and material of the inflatable balloon are selected such that when inflated, the balloon conforms to the shape of the complex vasculature, or at least a portion thereof, without appreciably deforming the vessel walls. In this manner, the balloon can be used to control flow in the vasculature, for example occluding a selected branch of the vasculature during introduction of material in order concentrate the material and minimize its disbursement by blood flow.
