Fluid exchange system for controlled and localized irrigation and aspiration
First Claim
1. A system for irrigation and aspiration within a localized region of the body comprising:
- a fluid exchange apparatus comprising an irrigation reservoir and irrigation lumen having means for controlled delivery of irrigant fluid from the irrigation reservoir through the irrigation lumen to a target site;
an aspiration lumen having means for controlled collection of aspirant fluid through an aspiration lumen; and
a catheter element comprised of the irrigation or aspiration lumen, wherein the irrigation lumen terminates with at least one irrigation port at a distal end of the catheter element and the aspiration lumen terminates with at least one aspiration lumen such that fluid volume exchange occurs between the at least one irrigation port and the at least one aspiration port.

Abstract
The control of fluid introduction into and out of body conduits such as vessels, is of great concern in medicine. As the development of more particular treatments to vessels and organs continues it is apparent that controlled introduction and removal of fluids is necessary. Fluid delivery and removal from such sites, usually referred to as irrigation and aspiration, using fluid exchange devices that control also need to be considerate of potential volume and/or pressure in the vessel or organ are described together with catheter and lumen configurations to achieve the fluid exchange. The devices include several electrically or mechanically controlled embodiments and produce both controlled and localized flow with defined volume exchange ratios for fluid management. The applications in medicine include diagnostic, therapeutic, imaging, and uses for the introduction or removal of concentrations of emboli within body cavities.

16. A fluid exchange device for fixed volume fluid exchange within a body lumen comprising:
-
means for producing a pulsatile flow within the body lumen comprising;
means for controlled delivery of a fixed volume of irrigant fluid from an irrigation reservoir through an irrigation lumen and an irrigation port located at the distal end of a catheter;
means for controlled collection of a fixed volume of aspirant fluid from an aspiration port located in the distal end of the catheter through an aspiration lumen and into aspiration reservoir, wherein the means for controlled delivery and means for controlled collection are linked and produce the fixed volume exchange of the irrigant fluid and the aspirant fluid by the pulsatile flow at a target fluid exchange site within the body lumen. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27)
