摘要：
Catheter systems and methods for facilitating the delivery of a therapeutic agent directly to the interior of a body organ, and/or the extraction of material from said organ. The catheter distal end is placed within the body organ to be treated. The catheter may carry a fixation device near the catheter distal end. When implanted, the fixation device retains the catheter distal end in the organ despite normal patient activity. The fixation device may include porous material to promote soft tissue ingrowth for anchoring the catheter distal end within the organ.
