Abstract: Described is a maneuverable endovascular catheter comprising an elongated and hollow body extending longitudinally and provided with a distal aperture, a proximal aperture, and a lateral aperture in fluid connection with the hollow body. The catheter is further provided with a steering line secured at the exterior distal aspect of the catheter. The steering line enters the interior lumen of the hollow body of the catheter through the lateral aperture and traverses the length of the hollow body. Tension applied to the proximal end of the steering line may deflect the distal aspect of the catheter according to the amount of force applied. The maneuverable endovascular catheter described may be used in endovascular surgeries or procedures.

Abstract: A detector for detecting vapors emitted from analytes includes a housing, a pump and a sensing assembly. The housing has an inlet, an outlet and an enclosed sensing volume therebetween. The pump communicates with the housing for moving a carrier sequentially through the enclosed sensing volume at a predetermined flow rate. The sensing assembly senses the vapors of the analyte delivered by the carrier as the carrier passes through the housing. The sensing assembly includes a sensing unit constructed of an amplifying fluorescent polymer, a source of excitation, a detector, and a convertor assembly.
