Abstract: In some examples, a catheter body includes an outer jacket positioned over a structural support member. A proximal portion of the structural support member comprises a straight or tapered polymer hypotube and a distal portion of the structural support member comprises a distal support member that is more flexible than the polymer hypotube. In some examples, the polymer hypotube defines one or more openings, through which an adhesive may be introduced between the polymer hypotube and an inner liner of the catheter body.

Abstract: A method for operating an exhaust gas system is provided. The method includes determining an amount of a reducing agent to be supplied to the exhaust gas of an engine and evaluating measurements which indicate a content of nitrogen oxides in the exhaust gas downstream of a catalytic device adapted to diminish the content of nitrogen oxides. A magnitude and a frequency of the measurements are taken into account in determining the amount of the reducing agent to be supplied. A plurality of measurements is captured during a predetermined period of time. A magnitude of a measurement captured within this period of time is related to a quantity derived from the respective magnitudes of the plurality of measurements. The related measurement is utilized to determine the amount of the reducing agent to be supplied. A control assembly for operating an exhaust gas system is also provided.

Abstract: A method and a control assembly for operating an exhaust gas system of a motor vehicle is disclosed. Measuring values are evaluated, which indicate a content of nitrogen oxides in an exhaust gas downstream of a catalytic device. The catalytic device is adapted to diminish the content of nitrogen oxides in the exhaust gas produced by an engine of the motor vehicle. Based on the measuring values a quality of a reducing agent supplied to the catalytic device is assessed. The method includes determining whether reducing agent has been filled into a storage tank. A plurality of measuring values is captured during a predetermined period of time, and a magnitude and a frequency of the plurality of measuring values are taken into account to assess the quality of the reducing agent.
