Abstract

A catheter capable of rapid inflation and deflation and operation by one individual.

Claims

1. 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.

2. The catheter of claim 1, wherein the catheter is capable of inflating the balloon in less than about one second.

3. The catheter of claim 1, wherein the catheter is capable of deflating the balloon in less than about five seconds.

4. The catheter of claim 1, wherein the catheter is capable of deflating the balloon in about one second.

5. The catheter of claim 1, wherein the catheter shaft includes an independent lumen to deliver one or more beneficial agents.

6. The catheter of claim 1, wherein the shaft includes three independent lumen extending from a proximal section and a distal section of the shaft, and further wherein the lumen are juxtaposed to form an I-beam shaped polymeric web aligned transversely to the longitudinal axis of the lumen.

7. The catheter of claim 1, wherein the balloon is a compliant balloon.

8. The catheter of claim 7, wherein the balloon is sufficiently compliant to shape to a blood vessel when introduced within the vessel.

9. The catheter of claim 1, wherein the balloon is spiral shaped or fluted shaped.

10. 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.

11. The catheter of claim 10, wherein the arming device pierces the reservoir to permit release of inflation fluid into the inflation lumen.

12. The catheter of claim 11, wherein the inflation fluid is a gaseous substance.

13. The catheter of claim 10, wherein the catheter includes an indicator disposed between the balloon and a check valve associated with the deflation lumen.

14. The catheter of claim 10, wherein the catheter facilitates improved infarct size after an ischemic event in a subject.
