Patent ID: 7803141

Claim:
A device for direct delivery of a shear thickening fluid having therapeutic properties to a target site, the device comprising: a channel having a proximal end, a distal end and a central lumen extending therethrough, the central lumen having a longitudinal axis, the channel containing a shear thickening fluid having therapeutic properties, the channel configured to expose the shear thickening fluid to a viscosity adjuster; wherein the viscosity adjuster comprises at least two non-overlapping projections extending from one or more walls of the channel and leaving an open flow channel coincident with the central lumen's longitudinal axis, wherein the viscosity adjuster's at least two non-overlapping projections are located at the same point along the central lumen's longitudinal axis and define at least one constricted flow orifice perpendicular to the central lumen's longitudinal axis.
