Multilumen catheter for minimizing limb ischemia
First Claim
1. A method of treating a patient, comprising:
- providing an apparatus comprising;
a first elongate body having a first proximal end, a first distal end, and a first lumen extending therebetween; and
a second elongate body having a second proximal end, a second distal end, and a second lumen extending therebetween;
advancing the second elongate body percutaneously into a patient such that an outer surface thereof engages a femoral artery at an access point and the second distal end is between the access point and the aorta;
advancing the first elongate body in coaxial relationship with the second elongate body into the vasculature until the first distal end is at a location within the aorta of the patient;
configuring the second elongate body to permit blood to flow downstream of the access point to minimize ischemia.

Abstract
A multilumen catheter that maximizes the blood flow into and out of the patient'"'"'s vasculature while also providing for passive and/or active perfusion of tissue downstream of where the catheter resides in the vasculature. The inventive catheter comprises a proximal end, a first distal and a second distal end with first and second lumens extending from the proximal end to each of these distal ends to provide for blood circulation within one blood vessel or between two different blood vessels. The second lumen, and any additional lumens so desired, may be positioned coaxially with or radially around the first lumen. Redirecting means is provided at a distal end of at least one of said lumens for directing blood in a direction generally opposite of the direction of flow through said lumen.
