Devices for repair of a selected blood vessel or part thereof and rapid healing of injured internal body cavity walls

Abstract

Abstract The invention relates to an apparatus comprising a catheter having a catheter body with a distal end and a proximal end; a light emitter disposed at the distal end of the catheter body and configured to emit light; a fluid conduit disposed in the catheter body, extending from the proximal end to the distal end of the catheter body, having an inlet at the proximal end of the catheter body and coupleable to a source of fluid and having an outlet at the distal end and configured to discharge fluid from the source via the conduit and out of the distal end; a spacing member disposed at the distal end of the catheter body and reconfigurable from a collapsed configuration to an expanded configuration, in the expanded configuration the spacing member disposed about the light emitter to maintain the light emitter approximately centered within the spacing member with respect to at least one axis of the spacing member, the spacing member at least partially transmissive and / or transflective of the light emitted from the light emitter; the apparatus configured for the distal end of the catheter body to be inserted at least partially into a body lumen having an interior wall, for the spacing member to be disposed in the expanded configuration within the body lumen, for fluid to be discharged into the body lumen, and for light to be emitted from the light emitter to illuminate the interior wall of the body lumen.
