Abstract: This disclosure relates to RNA interference (RNAi) compositions that target expression of heat shock protein 90 (HSP90) in a subject. Polymeric delivery devices for providing the RNAi compositions are also described, as are methods of treating cancer using the described RNAi compositions.

Abstract: The present invention relates to a system and method for the delivery of a treatment element, and in particular, to such a system and method in which an implantable treatment element is implanted at a target site.

Abstract: Implantable medical device eluting drug locally and in prolonged period is provided, including several types of such a device, the treatment modes of implementation and methods of implantation. The device comprising of polymeric substrate, such as a matrix for example, that is used as the device body, and drugs, and in some cases additional scaffolding materials, such as metals or additional polymers, and materials to enhance visibility and imaging. The selection of drug is based on the advantageous of releasing drug locally and in prolonged period, where drug is released directly to the extracellular matrix (ECM) of the diseased area such as tumor, inflammation, degeneration or for symptomatic objectives, or to injured smooth muscle cells, or for prevention. One kind of drug is the gene silencing drugs based on RNA interference (RNAi), including but not limited to si RNA, sh RNA, or antisense RNA/DNA, ribozyme and nucleoside analogs.
