Abstract: A flexible belt is disclosed for use in a printing system. The belt comprises an endless strip which, in use, travels along a continuous path. Formations are provided along the sides of the strip which are capable of engaging with lateral tracks to place the belt under lateral tension, the lateral tracks further serving to constrain the belt to follow the continuous path.

Abstract: A method for injecting a therapeutic agent into a target tissue, the method comprising: (a) providing an expandable member; (b) positioning said expandable member in proximity to the target tissue; (c) Introducing the therapeutic agent into the expandable member until a desired pressure is achieved; and (d) creating a plurality of small apertures in the expandable member.

Abstract: A pressure sensitive valve comprising: (a) an outer balloon adapted for intravascular insertion comprising at least one hole adapted for ejection of a fluid; (b) an inner structure adapted to substantially fill the outer balloon; (c) at least one selectively blockable flow path between the outer balloon and the inner structure, at least some of the at least one flow path in fluid communication with at least one of the at least one hole; (d) an inlet port to the at least one flow path; and (e) a pressure source operable to provide a fluid at least at a selected injection pressure to the inlet port. A flow of the fluid along the at least one selectively blockable flow path to the at least one hole is prevented when the pressure source provides any pressure below the selected injection pressure and a flow of the fluid along the at least one selectively blockable low path to the at least one hole occurs when the pressure source provides pressure at or above the selected injection pressure.

Abstract: A balloon for injecting material into a wall of a hollow organ of a human, comprising: an expandable balloon body having a surface and having an axis; at least one predefined ejection port on said body adapted for ejection of fluid therefrom, in a transaxial direction; and an impulse source configured for and adapted to eject material out of said point at a velocity and shape suitable for mechanically penetrating tissue adjacent said port.
