Integrated infusion and aspiration system and method
First Claim
1. A system for percutaneous infusion and aspiration of an internal wound site, the system comprising:
- a catheter assembly comprising;
an aspiration catheter having a proximal section and an opposing distal section, the aspiration catheter bounding a first lumen extending along the length thereof, at least one port being formed on the distal section of the aspiration catheter so as to communicate with the first lumen; and
an infusion catheter having a proximal section and an opposing distal section, the infusion catheter bounding a second lumen extending along the length thereof at least one port being formed on the distal section of the infusion catheter so as to communicate with the second lumen, at least a portion of the aspiration catheter or infusion catheter being disposed within the lumen of the other of the aspiration catheter or infusion catheter, the distal section of the aspiration catheter and the distal section of the infusion catheter being spaced apart from each other so as not to be disposed within the lumen of the other;
a medication reservoir in fluid communication with the proximal section of the infusion catheter;
a first pump adapted to transfer fluid from the medication reservoir to the infusion catheter;
an aspiration reservoir in fluid communication with the proximal section of the aspiration catheter;
a second pump adapted to draw fluid from the aspiration catheter to the aspiration reservoir; and
an electronic controller which selectively controls both the flow rate of the fluid through the infusion catheter and the flow rate of fluid through the aspiration catheter.

Abstract
An integrated infusion and aspiration system includes of a flow control system and a catheter assembly. The catheter assembly includes an infusion catheter and an aspiration catheter, each having ports located at the distal end of thereof. The distal ends of the catheters are separated so that the aspiration catheter ports can be positioned on an opposing side of a surgical wound site from the infusion catheter ports. Methods of operation of the integrated infusion and aspiration system provides for uninterrupted aspiration with concurrent controlled delivery of an infusion solution such that the infusion solution is substantially evenly dispersed of over the wound site.
