Method for treating a wall of a blood vessel
First Claim
1. A method for treating a wall of a vessel, the vessel having a vessel pH level, the method comprising the steps of:
- providing a fluid having a fluid pH level which is different from the vessel pH level, at least a portion of the fluid precipitating at approximately the vessel pH level; and
dispensing the fluid into the wall of the vessel to allow at least a portion of the fluid to approach the vessel pH level and precipitate.

Abstract
A method and device for injecting fluid into a treatment area of a vessel wall is provided herein. A first version of the device includes an inflatable balloon mounted on a catheter and a plurality of dispensers extending outwardly and moving with the balloon. At least one fluid passageway connects each injector in fluid communication with a fluid source. During use of the device, the balloon is first positioned in a vessel proximate the treatment area. Next, the balloon is inflated to embed the dispensers into the vessel wall. Subsequently, the fluid from the fluid source is introduced into the fluid passageway and through the dispensers into the treatment area. A second version of the device 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. The dispensers 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 The push-pull wire is then partially withdrawn forcing the grommet to advance towards the multi-lumen catheter.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 dispensers into the vessel wall.
