Abstract
A device for injecting medication into a vessel wall includes a plurality of flexible tubes mounted between a multi-lumen catheter and a grommet. A push-pull wire is connected to the grommet and passed through a lumen of the multi-lumen catheter. A plurality of injectors are mounted on each of the flexible tubes. During use, the device is first positioned in a vessel. The push-pull wire is then partially withdrawn forcing the grommet to advance towards the multi-lumen catheter. The advancing grommet forces the flexible tubes to bow outwardly, embedding the injectors into the vessel wall. A fluid medication is then introduced through the multi-lumen catheter, into the flexible tubes and out of the injectors for infusion into the vessel wall.
