Abstract
Abstract A catheter that can be used for concurrent fluid infusion and aspiration in humans, animals and biological material, at a wide range of flow rates, without any blockage problems. The catheter is composed of two concentric tubes; their proximal ends are properly connected to the infusion equipment and the aspiration equipment respectively; the distal end of the catheter is covered by a filter or membrane or grid or mesh cage and contains a hydrodynamically moving device of concurrent infusion and aspiration. The inner tube is properly assembled to the moving infusion and aspiration device, which irrigates the space surrounding the catheter's tip, through the filter or membrane or grid or mesh cage cover preserving its permeability, while it helps, due to its motion, the aspiration through the outer tube.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
136 words
1 . An endotherapy catheter, comprising an infusion lumen-tube connected at a proximal end to a pump, bottle or any apparatus that contains fluids for infusion under positive pressures, an aspiration lumen-tube connected at a proximal end to a pump, bottle or any apparatus that collects fluids under negative pressures, of a filter, membrane, grid or mesh cage positioned at a distal end of the catheter, through which infusion and aspiration takes place, and of a hydrodynamically moving device, positioned inside the filter, membrane, grid or mesh cage, which directs infused fluid, through the surface of the filter, membrane, grid or mesh cage, to the catheter's surrounding space, thereby preventing biological material deposition and consequent blockage of a distal catheter tip, and simultaneously, due to its motion, improving the aspiration of the fluid surrounding the catheter.
Claim 2
Dependent Claim
136 words
1 . An endotherapy catheter, comprising an infusion lumen-tube connected at a proximal end to a pump, bottle or any apparatus that contains fluids for infusion under positive pressures, an aspiration lumen-tube connected at a proximal end to a pump, bottle or any apparatus that collects fluids under negative pressures, of a filter, membrane, grid or mesh cage positioned at a distal end of the catheter, through which infusion and aspiration takes place, and of a hydrodynamically moving device, positioned inside the filter, membrane, grid or mesh cage, which directs infused fluid, through the surface of the filter, membrane, grid or mesh cage, to the catheter's surrounding space, thereby preventing biological material deposition and consequent blockage of a distal catheter tip, and simultaneously, due to its motion, improving the aspiration of the fluid surrounding the catheter.
