IMPLANTABLE AND REFILLABLE DRUG DELIVERY RESERVOIR

摘要

Implantable drug delivery apparatuses and methods are described. An input port septum receives a therapeutic drug. An implantable delivery catheter holds a volume of the therapeutic drug and includes a proximal end in fluid communication with the input port septum, a distal end including an output septum for removing fluid from the catheter, and a drug permeable surface for diffusion of the therapeutic drug into nearby tissue.
