Beschreibung
Zusammenfassung:	An apparatus for delivering an agent to a treatment area. The apparatus includes a catheter that has a distal portion and a proximal portion. The catheter defines a lumen. A pressure regulator is in fluid communication with the lumen. A selectively inflatable member is also in fluid communication with the lumen, and is formed from a membrane. The membrane has first and second portions. The first portion defines pores sized from about 0.05 mu to about 1 mu and has a pore density from about 106 pores/cm2 to about 109 pores/cm2. The flux rate is from about 0.001 ml/(minxcm2xatm) to about 0.4 ml/(minxcm2xatm). The second portion is substantially impermeable.
