METHOD AND DEVICES FOR FLOW OCCLUSION DURING DEVICE EXCHANGES
First Claim
1. A method of treating an injured blood vessel of a patient, the method comprising:
- inflating a balloon of an access wire balloon catheter within the injured blood vessel to reduce blood flow past an injury site in the vessel;
attaching an extension wire to an extra-corporeal end of the access wire balloon catheter that resides outside the patient, wherein, when the extension wire is attached, an inflation port of the access wire device is disposed outside the patient and between a free end of the extension wire and the balloon of the access wire balloon catheter;
advancing at least a first treatment catheter into the blood vessel over the access wire balloon catheter and at least a portion of the extension wire; and
treating the injured blood vessel using the first treatment catheter.

Abstract
A method of treating an injured blood vessel of a patient may first involve inflating a balloon of an access wire balloon catheter within the injured blood vessel to reduce blood flow past an injury site in the vessel. After inflation, the method may involve attaching an extension wire to an extra-corporeal end of the access wire balloon catheter that resides outside the patient. When the extension wire is attached, an inflation port of the access wire device is disposed outside the patient and between a free end of the extension wire and the balloon of the access wire balloon catheter. The method may further include advancing at least a first treatment catheter into the blood vessel over the access wire balloon catheter and at least a portion of the extension wire and treating the injured blood vessel using the first treatment catheter.

8. A system for facilitating treatment of an injured blood vessel of a patient, the system comprising:
-
an access wire balloon catheter, comprising; an elongate tubular body with a proximal end, a distal end, and a lumen extending longitudinally through at least part of the body; an inflatable balloon disposed on the elongate body closer to the distal end than to the proximal end and in communication with the lumen; a valve at or near the proximal end of the elongate body configured to couple with an inflation device to allow for inflation and deflation of the balloon; and a first coupling member at the proximal end; and an extension wire having a second coupling member at one end, wherein the first and second coupling members are configured to attach to one another to connect the proximal end of the access wire balloon catheter with one end of the extension wire, wherein an outer diameter of the access wire balloon catheter is approximately the same as an outer diameter of the extension wire, at least in an area around a connection between the access wire balloon catheter and the extension wire. - View Dependent Claims (9, 10, 11)

12. A device for facilitating treatment of an injured blood vessel of a patient, the device comprising:
an extension wire having a coupling member at one end for coupling with a corresponding coupling member on an access wire balloon catheter device used to occlude blood flow in the injured blood vessel, wherein an outer diameter of the extension wire is approximately the same as an outer diameter of the access wire balloon catheter, at least in an area around a connection between the extension wire and the access wire balloon catheter. - View Dependent Claims (13, 14, 15)
