摘要： A system and method for controlling the inflation, ablation, and deflation of a balloon catheter. The system includes a balloon catheter, a console, a pressurized gas or liquid inflation source, and an umbilical system to deliver pressurized coolant to the balloon catheter. The system may include controller that monitors the amount of pressure and volume within the balloon catheter. During inflation, the pressure and/or volume of fluid within the balloon is maintained at a target amount in order to provide sufficient mechanized pressure against the desired target region. The system limits the inflation pressure such that a safe quantity of gas would be released should a leak occur. If the amount falls below a certain threshold level, gas or fluid egress is presumed and the inflation process is halted.

摘要： A medical apparatus and system for determining contact assessment includes a catheter having an elongate body having a proximal end, a distal end opposite the proximal end, and defining an injection lumen and an exhaust lumen, an expandable membrane defining a cooling chamber disposed at a point along the elongate body, the cooling chamber in fluid communication with the injection lumen and the exhaust lumen, and a contact assessment element which may be a temperature sensor located proximate the coolant return lumen for measuring an internal temperature of the chamber. The system may include the catheter, a console having a fluid supply, an exhaust path and at least one control mechanism operationally coupled to the temperature sensor for processing a temperature signal received from the temperature sensor. The apparatus and system can also have multiple electrodes to measure and process various impedances to determine contact assessment.

摘要： The present invention provides a medical device having an elongate body with both a proximal end and a distal end, wherein the elongate body defines an intake lumen and an exhaust lumen. The medical device also has a first pliable element defining a cooling chamber disposed at a point along the elongate body, with the cooling chamber being in fluid communication with the intake lumen and the exhaust lumen. A second pliable element is provided which at least partially encloses the first pliable element, thereby defining a junction between the first and second pliable element. Moreover, a check valve is included which is in fluid communication with the junction between the first pliable element and second pliable element, the valve further being in fluid communication with the exhaust lumen. In addition, the medical device may include sensors or other monitoring means in fluid communication with the junction and the cooling chamber.

摘要： A system (10) and method for controlling the inflation, ablation, and deflation of a balloon catheter (1) is provided. The system includes a balloon catheter (1), a console (20) having a pressurized gas or liquid inflation source, and an umbilical system (12) to deliver pressurized coolant to the balloon catheter (1). The system (10) comprises a PID (Proportional Integral Derivative) controller or other pressure-sensing device that monitors the amount of pressure and volume within the balloon catheter. During inflation, the pressure and/or volume of fluid within the balloon (23) is maintained at a target amount in order to provide sufficient mechanized pressure against the desired target region. The system limits the inflation pressure such that a safe quantity of gas would be released should a leak occur. If the amount falls below a certain threshold level, gas or fluid egress is presumed and the inflation process is halted.
