Apparatus and a method for treating an irregularity in a wall of a vessel of a patient defined by an irregular or afflicted wall portion with adjacent normal wall portions comprises a catheter having a distal end portion for being guided through the vessel to the site of the irregularity. The deformation of the wood fiber board which can be achieved with the invention is known in the art as extusion, wherein a considerable plastic deformation takes place accompanied by flow and stretch of the material. A frame representing the packet for transmission is generated over a satellite link to a user terminal. The organic compound layer is formed so as to be sandwiched between a pair of electrodes and, preferably, formed by a plurality of layers each having a different carrier transport property and a different light emission wavelength. In response to the event, the extensible phone application sends the notification to the extension.
