Abstract: An endograft includes a main body having a wall separating interior and exterior surfaces and adapted to be inserted within the vessel. The main body is characterized by a single proximal opening and two distal openings and at least one aperture extending through the wall. At least one stent is secured to the main body that upon expansion pressure fits the main body into the vessel. An open tunnel is secured to the interior surface of the main body around the main body aperture and secured somewhere along the tunnel length to provide fluid communication between the interior and exterior surfaces of the main body through the aperture and with the vascular branch in proximity to the main body aperture. The insertion of a sleeve positioned partly within the tunnel and extending beyond the exterior surface of the main body into the vascular branch assures to the vascular branch.

Abstract: An endograft for a vessel having a vascular branch extending from the vessel is provided. The endograft includes a main body having a wall separating interior and exterior surfaces and adapted to be inserted within the vessel. The main body is characterized by a single proximal opening and two distal openings and at least one aperture extending through the wall. At least one stent is secured to the main body that upon expansion pressure fits the main body into the vessel. An open tunnel is secured to the interior surface of the main body around the main body aperture and secured somewhere along the tunnel length to provide fluid communication between the interior and exterior surfaces of the main body through the aperture and with the vascular branch in proximity to the main body aperture. The tunnel is readily formed independent of an expandable stent.

Abstract: The present invention relates to an arrangement and a method for providing user station with access to (a) service providing network(s). It comprises a radio access network control node (RANCN) (3) acting as a gateway node between WLAN access points (AP) (2A,2B;4) and the service providing network, and it comprises connection processing means for adapting service providing network transport protocols such that a WLAN supporting user station (1A,1B;1) can access the service providing network services over the WLAN radio interface.

Abstract: The present invention relates to an arrangement and a method for providing a user station with access to (a) service providing network(s) over a wireless radio access network, particularly Bluetooth. It comprises a radio access network control node (RANCN) (3) acting as a gateway node between access stations (HBS; 2A,2B) and the service providing network, and it comprises connection processing means for adapting service providing network transport protocols such that the user station (1A,1B) can acces the service providing network services over the radio interface of the wireless radio access network, whereby the 15 radio access network control node (3) reuses a set of service network transport protocols for communication over the radio access network, the reused protocols being tunneled using the Internet Protocol (IP) through an access station (HBS; 2A,2B) connected to the radio access network control node (3).

Abstract: A valve for controlling the flow of a gas therethrough which requires no machining in order to attain an effective seal between the valve seating surface and a rotatable plug element. The valve seat surface remains as cast while the plug consists of an overmolded plastic. The overmolding defines an array of pliable sealing ridges. The use of overmolding facilitates the use of cost-saving plastic materials, and obviates the need for expensive machining of the cooperating surfaces.
