Claims14
A catheter system comprising,
- a catheter shaft and a single balloon disposed on the catheter shaft, the single balloon having an inflation port connected with an inflation lumen and a deflation port connected to an independent deflation lumen, wherein the catheter is capable of being operated by one person to actuate inflation of the balloon in less than about four seconds;
- and
- a handle capable of hand-carrying and comprising a reservoir for supplying fluid to the catheter shaft and balloon, wherein a fluid circuit is defined by the catheter shaft, balloon, and handle.
A catheter system, the catheter comprising:
- a catheter shaft and a single balloon disposed on the catheter shaft,
- a reservoir housing inflation fluid,
- an inflation lumen and a separate deflation lumen connected to the single balloon, the inflation and deflation lumen providing independent fluid communication between inflation and deflation ports and the interior of the balloon, and
- a non-reversible arming device to allow flow of the inflation fluid from the reservoir to the inflation lumen.
