1. A process for delivering a protein or peptide to an extravascular cell in a mammalian target tissue in vivo comprising:
- inserting an injection solution containing the protein or peptide into the lumen of an efferent or afferent vessel of the target tissue wherein the inserting of the injection solution results in an increase in pressure in a vein of the target tissue of 10 mm Hg or greater thereby resulting in delivery of the protein or peptide to the extravascular cell.

Abstract
Disclosed is a system for providing in vivo delivery of molecules or complexes to extravascular mammalian cells using an intravascular administration route. The molecules or complexes are inserted in an injection solution into a mammalian vasculature. Insertion of the injection solution at an appropriate rate transiently increases the volume of extravascular fluid in the tissue thereby facilitating delivery of the molecule to the cell.

25. A process for delivering a protein or peptide to an extravascular in vivo mammalian cell in a target tissue comprising:
- rapidly inserting a sufficient volume of injection solution containing the protein or peptide into the lumen of an efferent or afferent vessel of the target tissue and impeding fluid flow away from the tissue during the injection wherein the inserting of the injection solution results in an increase in pressure in a vein of the target tissue of 10 mm Hg or greater thereby resulting in delivery of the protein or peptide to the extravascular mammalian cell in the tissue.
