Abstract

The present invention relates to a catheter that includes an elongate body having distal and proximal ends, the elongate body having at least one lumen therethrough, a distal portion of the elongate body having a perimeter. First and second retention members of the catheter are first and second retention members selectively disposed in either an insertion state or a retention state. In the insertion state, the first and second retention members form a distal body defining a central axis, the central axis being generally spaced apart from the perimeter of the distal portion of the elongate body, the distal body and elongate body insertable along a passageway of a mammal. In the retention state, the first and second retention members are selectively disposed in a spaced apart configuration to resist proximal movement of the catheter along the passage of the mammal.
