    • An implantable catheter or shunt (24) for draining fluid from a body cavity. The catheter or shunt body has a wall structure (28) that carries one or more therapeutic agents (26) in a manner enabling release of the therapeutic agent from the wall structure in situ after surgical implantation of the catheter or shunt body. The therapeutic agent can be gradually released over time to prevent infection, inhibit tissue ingrowths, and/or provide some other desired medicinal purpose. As an example, the therapeutic agent can be rapamycin or an mTOR inhibitor. According to some contemplated embodiments of the present invention, the therapeutic agent carried by the catheter/shunt is rechargeable or refillable in situ so that the therapeutic agent can be gradually released from the catheter/shunt over the expected useful life of the catheter/shunt.
    • 用于从体腔排出流体的可植入导管或分路器(24)。 导管或分流体具有壁结构(28),该壁结构承载一种或多种治疗剂(26),以使得能够在手术植入导管或分流体之后将治疗剂从壁结构释放。 治疗剂可以随着时间逐渐释放以防止感染,抑制组织向内生长和/或提供一些其它期望的药物用途。 作为实例,治疗剂可以是雷帕霉素或mTOR抑制剂。 根据本发明的一些预期的实施例,由导管/分流器承载的治疗剂可以在现场进行可再充电或可再填充,使得治疗剂可以在导管/分流器的预期使用寿命期间从导管/分流器逐渐释放。
