Patent ID: 7967776

Claim:
A dual lumen cannula adapted for insertion at a point of insertion for use in peritoneal dialysis, hemodialysis or hemofiltration, the cannula comprising: a first cannula body having a proximal end, a distal end, and a first lumen extending between the proximal and distal ends, and a second cannula body having a proximal end, a distal end, and a second lumen extending between the proximal and distal ends, wherein, the lumen of the first and second cannula bodies each include a corresponding diameter, the diameter of the first and second lumen may be varied, and at least one of the first and second distal ends further comprise a tip, wherein the tip is removable or eccentrically located; wherein at least one of the cannula bodies comprises a plurality of flexible filaments; at least one mechanism that, upon actuation, serves to alter the conformation of the first cannula body and/or the second cannula body, between a normal profile conformation and a low profile conformation; wherein, the lumen diameters of at least one of the first and second cannula bodies distal to the point of insertion are expandable up to the diameter of a surrounding vessel, environment, or to the maximum lumen diameter.
