Treatment of diseases by site-specific instillation of cells or site-specific transformation of cells and kits therefor
First Claim
1. A method of transfecting cells at a blood vessel wall or in tissues surrounding the blood vessel wall, comprising site specifically delivering an antisense agent into the blood vessel in an amount sufficient to transfect the cells, wherein the antisense agent is complementary to a region of a target gene expressed by the cells and wherein the antisense agent is delivered via a catheter.

Abstract
A method for the direct in vivo transformation of cells in and surrounding a solid tumor is disclosed. This method is based on the site-specific delivery of proteins to solid tumors and to tissue surrounding the solid tumor by direct injection of a nucleic acid sequence. In particular, this method is directed to site-specific delivery of nucleic acids encoding major histocompatibility proteins, cytokines, and toxins to a solid tumor. This technique provides for the transfer of vectors and expression of recombinant genes in vivo and allows the introduction of proteins of therapeutic or diagnostic value for the treatment of disease.

- 4. A method of delivering an antisense agent to a site at a blood vessel wall or in tissues surrounding the blood vessel wall, comprising introducing the antisense agent into the blood vessel wall or tissues surrounding the blood vessel wall via a catheter and releasing the antisense agent in an amount sufficient to transform cells of the blood vessel wall, cells in tissues surrounding the blood vessel wall or both.
