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.

Abstract: An apparatus and method for limiting access to a septum in a body implanted device. The apparatus includes a screen member which covers the septum. The screen member has a plurality of openings which are sized such that needles larger than a predetermined size will not pass through the openings. Needles of a size less than the predetermined size of the openings will pass through and be provided access to the septum.

Abstract: A catheter (22) comprises proximal end (24) connected to a pump (20) and at least one distal end (26) fitted with a radio-opaque porous tip (60) made from a fritted metal such as tungsten, tantalum or titanium with pores of 0.3 - 6.2 microns diameter. The distal ends are connected to the main catheter by a Y-shaped connector (50) with optional regulators to balance the flow in the branches.

Abstract: A medical catheter comprising a flexible tube having an outer wall and an inner wall, the inner wall defining a lumen, the lumen extending longitudinally along the flexible tube and having a cross-sectional area; and a flexible core within the lumen substantially extending longitudinally along the flexible tube, the flexible core having a cross-sectional area smaller than the cross-sectional area of the lumen at any given longitudinal point along the flexible tube and flexible core, the flexible tube and the flexible core defining a passageway, and which in combination provides structure resistant to occlusion of the passageway.

Abstract: A catheter system and method for intracranial infusion of therapeutic substances to a patient. An anchor formed of generally flexible, elastomeric material is used to mount the catheter to the outer surface of the skull of the patient. The anchor has a through hole for receiving the catheter, a channel, extending substantially from the through hole, into which a portion of the catheter may be inserted to retain the portion substantially parallel to the surface of the skull, and at least one flange for engaging the outer surface of the skull. An anchor clip may be provided to engage the anchor adjacent the through hole to further stabilize the catheter.
