METHOD AND APPARATUS FOR INFLATING AND DEFLATING BALLOON CATHETERS |
摘要 |
A system and method for controlling inflation, ablation, and deflation of a balloon catheter, including a catheter, a console having a pressurized gas or liquid inflation source, and an umbilical system to deliver coolant. A pressure-sensing device monitors pressure and volume within the catheter. During inflation, pressure and/or volume of fluid within the balloon is maintained to provide sufficient pressure against the target region. Inflation pressure is limited so a safe quantity of gas would be released should a leak occur. If the amount falls below a threshold, fluid egress is presumed, halting inflation. An intermediate console having a shut-off valve may be coupled between the console and catheter to interrupt coolant flow upon leak detection. The balloon can be re-inflated by a separate coolant source in the intermediate station or by a syringe. A second balloon may envelope the first balloon, providing a safety vacuum between the two balloons. |
