Fluid exchange system for controlled and localized irrigation and aspiration
First Claim
1. A mechanical device for creating turbulent fluid exchange 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 and an aspiration lumen having means for controlled collection of aspirant fluid, wherein the means for controlled delivery of irrigant fluid and the means for controlled collection of aspirant fluid are mechanically linked to produce simultaneous delivery of irrigant fluid and removal of aspirant fluid, and wherein the fluid exchange apparatus is hand held and is comprised of a trigger actuated to simultaneously exert force on the means for controlled delivery of irrigant fluid and the means for controlled collection of aspiration fluid, and a catheter element comprised of the irrigation or aspiration lumen a both, 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 port, wherein the at least one irrigation port and the at least one aspiration port are oriented to produce turbulent fluid exchange from the simultaneous delivery of irrigant fluid and removal of aspirant fluid.

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.
