Abstract
A programmable manifold system for controlling pressure and fluid delivery within and through a catheter for use in a body lumen is disclosed. By means of a feedback loop controller, the system delivers known volumes of media through the catheter and into the body lumen and the system conforms the rate of change of pressure within the catheter to a desired value and makes possible consistent expansions and deflations using an automated or semi-automated system regardless of variations in catheter volume and compliance characteristics.
Claims17
An automatic fluid delivery system, comprising:
- a manifold having a plurality of ports, each port including a valve for controlling the flow of fluid therethrough;
- a fluid drive means for drawing fluid from and delivering fluid to said manifold via a first one of said ports;
- a catheter in fluid communication with said manifold via a second one of said ports;
- a fluid reservoir in fluid communication with said manifold via a third one of said ports;
- and
- means for controlling said valves and said fluid drive means to coordinate their operation to cause fluid from said reservoir to flow into said catheter through said manifold.
An automatic fluid delivery system, comprising:
- a manifold having a plurality of ports, each including a valve for controlling the flow of fluid therethrough;
- a fluid drive means for drawing fluid from and delivering fluid to said manifold via a first one of said ports;
- a balloon catheter in fluid communication with said manifold via a second one of said ports;
- a fluid reservoir in fluid communication with said manifold via a third one of said ports;
- and
- means for controlling said valves and said fluid drive means to coordinate their operation to cause fluid from said reservoir to pressurize said balloon catheter through said manifold.
An automatic fluid delivery system, comprising:
- a manifold having a plurality of ports, each port including a valve for controlling the flow of fluid therethrough;
- a fluid drive means for drawing fluid from and delivering fluid to said manifold via a first one of said ports;
- an inflatable balloon catheter in fluid communication with said manifold via a second one of said ports;
- a fluid reservoir in fluid communication with said manifold via a third one of said ports;
- and
- means for controlling said valves and said fluid drive means to coordinate their operation to cause fluid from said reservoir to flow into said catheter through said manifold and to apply controllable pressure to the inflatable balloon to control its inflation;
- and
- a pressure transducer in fluid communication with the balloon of the catheter operative to provide a signal to said controlling means indicative of pressure within said balloon;
- wherein said controlling means is programmed to vary the pressure within said balloon at a predetermined rate.
