Abstract:
1. A catheter for insertion into a vascular system of a patient and for directing fluid flow, the catheter comprising: a catheter body having a longitudinal axis and longitudinally spaced proximal and distal catheter ends with an intermediate catheter portion defined therebetween; an intermediate catheter outlet in the catheter body, located in the intermediate catheter portion, and spaced longitudinally from the distal catheter end; a first lumen defined within the catheter body and having longitudinally spaced proximal and distal first lumen ends with a reversing bend located therebetween, the first lumen providing fluid communication between the proximal catheter end and the intermediate catheter outlet; the reversing bend being located longitudinally between the intermediate catheter outlet and the distal catheter end, the reversing bend directing fluid flow to turn approximately 180° as the fluid flows through the first lumen; and an oximetric microcatheter adapted for: selective insertion into the proximal first lumen end, selective extension through the first lumen, and selective protrusion from the distal first lumen end in a cephalad direction.
