IMPLANTABLE SEALABLE SYSTEM FOR ONE-WAY DELIVERY OF THERAPEUTIC PREPARATIONS TO TISSUES

摘要

FIELD: medical engineering. ^ SUBSTANCE: device operates by subjecting organ to therapeutic drug action when making their contact through window or canal, providing in this way controllable, selective unidirectional drug diffusion into selected tissue or organ. The device gives protection to adjacent organs or tissue structures against exposure to excessive supplied drug doses. The device implements invented method for delivering chemotherapeutical drugs or biologically active substances to mammalians organs or tissues. ^ EFFECT: enabled selective and save diffusion control. ^ 57 cl, 23 dwg
