<p>The apparatus 10 employs a collapsible infusate reservoir 14 which is biased toward its collapsed condition to supply infusate under pressure to an outlet catheter 32 via a pair of parallel flow paths 22, 34 having different fluid restriction characteristics. The flow path 34 has a controllable valve 38 and a fluid accumulator 46 is connected to the path 34 upstream of the valve 38 so that infusate can be delivered to the catheter 32 via one or both paths 22, 34 depending upon whether the valve 38 is closed or open.</p> |
