Abstract: A gas sterilizable syringe includes an enclosure having walls that define a fluid chamber. A flowable material is disposed within the fluid chamber of the enclosure. A plunger is assembled with the enclosure and is moveable toward a distal end of the enclosure for dispensing the flowable material. One or more apertures are formed in at least one of the walls of the enclosure. A gas permeable barrier covers at least one of the apertures formed in at least one of the walls of the enclosure for enabling sterilization gases to pass through the at least one aperture covered by the gas permeable barrier while preventing the flowable material from passing through the at least one of aperture. The gas permeable barrier is permeable to the sterilization gases and impermeable to the flowable material disposed within the fluid chamber of the enclosure.

Abstract: There is provided signal modifying compositions for medical imaging comprising a carrier and signal modifying agents specific for two or more imaging modalities. The compositions are characterized by retention efficiency, with respect of the signal modifying agents that enables prolonged contrast imaging without significant depletion of the signal modifying agent from the carrier. The carriers of the present invention are lipid based or polymer based the physico-chemical properties of which can be modified to entrap or chelate different signal modifying agents and mixtures thereof and to target specific organs or tumors or tissues within a mammal.

Abstract: An apparatus for directing a user to a predefined location, which includes a receiver arranged to receive input information identifying the predefined location as well as an output device for tangibly communicating to the user information for directing the user to the predefined location. Advantageously, the user receives direction information via tactile information transfer means.
