ABSTRACT:
A medical catheter comprising a proximal end having an opening for fluid containing a therapeutic drug, a distal end, the distal end defining at least one opening, and a porous portion covering the opening defined by the distal end. In one embodiment, the medical catheter comprises a proximal end having an opening for fluid containing a therapeutic drug, at least two distal ends, the proximal end connected to the two distal ends with a connector, the distal ends each defining at least one opening, a diffuser covering the opening of each distal end, and a separate restrictor downstream of the connector and upstream of each distal end to provide substantially equal flow through each distal end. An additional restrictor can also be placed upstream of the connector. In another embodiment, a combination diffuser and restrictor covers the opening of each distal end. In one embodiment, the diffuser can define tubes that extend from the inside surface of the diffuser to the outside surface of the diffuser, to permit more equal drug flow through the tubes defined therein.
