US Patent 9084870 Catheter for uniform delivery of medication

The present invention provides a catheter for the delivery of fluid medication across an anatomical region. In accordance with some embodiments, the catheter includes a tube having a plurality of exit holes in a side wall of the tube and an elongated member positioned within the tube. The exit holes combine to form a flow-restricting orifice of the catheter. Advantageously, fluid within the catheter flows through all of the exit holes, resulting in uniform distribution of fluid within an anatomical region.
