Body lumen fluid delivery device
First Claim
1. A fluid delivery device, comprising:
- a flexible conduit having a proximal end and a distal end;
an image viewable zone disposed along an exterior of the flexible conduit at a predetermined location suitable for delivery of a fluid from the device and proximally located with respect to the distal end, the image viewable zone defined by one or more markers viewable in vivo by an imaging device; and
a lumen extending along an interior of the flexible conduit providing a fluid flow path between the proximal end and the distal end for a fluid injected into the flexible conduit, the lumen transitioning from a portion having a first cross-sectional flow area into a micro-lumen having a second cross-sectional flow area less than the first cross-sectional flow area, the micro-lumen exiting from the flexible conduit at a port at the image viewable zone, the port configured in such a way as to direct fluid out through the port along a longitudinal length of the flexible conduit and the image viewable zone in a direction primarily parallel with respect to a longitudinal axis of the flexible conduit, the port having a first cross-sectional flow area that is less than a second cross-sectional flow area.

Abstract
A method and apparatus for fluid delivery enables navigation through tortuous, spatially restricted body anatomy to access narrow diameter body lumens for the continuous delivery of fluids, including therapeutic fluids, to the lumen in an atraumatic manner that avoids damage to the body lumen. The fluid delivery device can have a flexible conduit having a proximal end, a distal end, and a lumen extending along an interior of the flexible conduit providing a fluid flow path between the proximal and distal ends, where the lumen transitions into a micro-lumen exiting through a port through which a high concentration of fluid injected into the lumen exits laterally out along an image viewable zone at the distal end of the flexible conduit. The flexible conduit has a maximum outer diameter sized sufficient to navigate narrow diameter body lumens.
