IMPLANTABLE DRUG DELIVERY DEVICE |
摘要 |
The invention pertains to implantable medical devices for controlled delivery of therapeutic agents. Some devices according to the invention have a titanium reservoir, and a porous titanium oxide based membrane to control the rate of release of the therapeutic agent. The reservoir contains a formulation of the active agent, and means to promote water uptake into the reservoir upon implantation. In some embodiments the means include a gas with a higher solubility in than air water. |
