Abstract (en)

[origin: CA2318132A1] A method and device for injecting fluid into a treatment area are provided herein. One embodiment includes a balloon (16) catheter (14), the balloon having a plurality of injectors (20) extending outwardly. Fluid passageways (26) connect each injector with a fluid source (60). During use, the balloon is positioned in a vessel proximate the treatment area (54) and inflated to embed the injectors into the vessel wall. The fluid is thereby introduced into the fluid passageway (26), through the injectors (20), and into the treatment area (54). The second embodiment includes flexible tubes (64) having aforementioned injectors (20). The tubes (64) are mounted between a multi-lumen catheter (14) and a grommet. A wire (38) connected to the grommet is passed through a lumen (27) of the catheter (14). Once the device is positioned in a vessel, the wire is partially withdrawn. This forces the grommet to advance towards the catheter (14), which thereby forces the flexible tubes (64) to bow outwardly, embedding the injectors (10) into the vessel wall.
