摘要

Apparatus for delivering therapeutic agents to the central nervous system of a subject is described. The apparatus comprises at least one intracrania l catheter and a percutaneous access device (50;140;150;160). The percutaneo us access device comprises a body (10;52;152) having at least one extracorpo real surface (22;68) and at least one subcutaneous surface, the body (10;52) defining at least one port (12;116) for connection to an implanted intracra nial catheter. The port (12;116) is accessible from the extracorporeal surfa ce (22;68) of the device, but is provided with a seal (14;112;142;146) such as a rubber bung between the lumen of the port and the extracorporeal surfac e (22;68). The percutaneous access device may have more than two ports (12;1 16) and/or a flange (26;54). A method of implanting the percutaneous access device(50;140;150;160) is also described.
