Abstract
The infusion stent system includes a stent member having a plurality of openings provided in the wall of the stent along the entire length of the stent. An imperforate open ended guide tube member used for installation and infusion of the stent accommodates a core member that stiffens the guide tube member. The core member is relatively moveable in the guide tube member to provide selective flexibility at a proximal end of the guide tube member. The stent is positioned in the renal cavity, the ureter and bladder by being pushed along the guide tube member by a push catheter. Fluid is infused through a proximal end of the guide tube member when the core member is removed. The proximal end of the guide tube member can be located at any selected position within the stent. Thus fluid can be infused to any selected location in the stent by positioning the proximal end of the guide tube member at a desired location in the stent. Openings in the stent that are bypassed by the guide tube member are not infused with fluid.
