1. A catheter system, comprising:

  • a catheter body having a proximal end, a distal end, at least one catheter body lumen running along a longitudinal axis from the proximal end through the distal end, and a lateral opening disposed on a periphery of the catheter body and in communication with the at least one catheter body lumen; and

    a reentry member comprising a reentry member lumen and a distal end, the distal end comprising;

    a first sharp edge parallel to the longitudinal axis to permit cutting, wherein the first sharp edge is formed on at least a portion of a bottom distal edge and extending outwardly from a surface of the reentry member, wherein the bottom distal edge is parallel to the longitudinal axis, the bottom distal edge being opposite a top edge of the reentry member;

    a second sharp edge to permit cutting, wherein the second sharp edge and the first sharp edge meet at an angle and form a distal tip of the distal end of the reentry member, wherein the angle is less than 90 degrees;

    wherein the reentry member is configured to flex from a first position inside the at least one catheter body lumen to a second position outside of the at least one catheter body lumen and through the lateral opening of the catheter body when an axial eccentric load is placed on the top edge of the reentry member.
