Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
107 words
A multi-lumened catheter having at least two lumens, one of said lumens being an oxygenation lumen and the other being an aspiration lumen, each of said lumens having an opening therein, and a protuberance whereby the aspiration lumen is spaced by said protuberance from approximate tissue surfaces, said lumens having a common flow control means in communication therewith and having multiple flow positions for controlling independently or simultaneously the flow through said lumens, said control means having a plunger means, said plunger means having a locking tab member affixed thereto for locking said plunger means into the desired flow position for controlling the flow through said lumens.
