Hemodialysis system and method |
摘要 |
A treatment assembly is positioned along an AV-fistula and couples therapeutic energy to an adjacent area due to a material response to an applied energy field from a remotely located energy source. The treatment assembly may be delivered into the fistula through a hemodialysis needle, or may be secured to the fistula graft itself and implanted therewith within a patient. A cover provides a shield between an anastomosis area and blood flow. Another AV-fistula includes a valved reservoir that receives a fluid agent from a hemodialysis needle while moving the needle into or from the fistula; the agent leaks from the reservoir into the fistula lumen. Another valved fistula is adjustable between an open condition and closed conditions during and between hemodialysis treatments, respectively. Another AV-fistula has a bladder reservoir coupled to a second refillable fluid reservoir and is adapted to locally deliver a therapeutic agent into the fistula lumen. |
