Abstract

A device far injecting medication into a vessel wall includes an inflatable balloon mounted on a catheter.
Additionally, a tubular sleeve surrounds the balloon to create an infusion chamber between the sleeve and the balloon, and a plurality of injectors are mounted on the sleeve in fluid communication with the infusion chamber.
During use of the device, the balloon is first positioned in a vessel and then inflated to embed the injectors into the vessel wall. Next, a fluid medicament is introduced into the infusion chamber for further infusion from the chamber and through the injectors into the vessel wall.
