Emboli removal system with oxygenated flow
First Claim
Patent Images
1. A medical treatment system comprising:
- an aspiration catheter comprising a suction device and a tube with an aspiration lumen and a distal aspiration port, the aspiration lumen being in fluid communication with the suction device; and
a profusion catheter comprising a reservoir of oxygenated blood and a tube with a profusion lumen and a profusion port providing an exit from the profusion lumen at or near the distal end of the profusion lumen, the profusion lumen being in fluid communication with the reservoir of oxygenated blood, wherein the profusion catheter and the aspiration catheter are configured such that the profusion catheter can be deployed within a vessel of a patient with the profusion opening downstream from the distal aspiration opening.

Abstract
Medical treatment systems incorporate inflow catheters to delivery oxygenated blood into a blood vessel. Devices suitable for the removal of emboli can be used with the inflow catheters. Suitable emboli removal structures include, for example, aspiration catheters and/or vascular filters. Blood removed with aspiration catheters can be filtered and returned to the patient through the inflow catheter.
