摘要:
A catheter system includes a proximal base having a distal diagonal end surface and a distal tip connected to the proximal base and movable relative to the proximal base, wherein the distal tip has a proximal diagonal end surface. The distal diagonal end surface and the proximal diagonal end surface contact opposing sides of a tissue portion to create the fistula. A peripheral edge defines the proximal distal end surface. A proximal point is disposed on the peripheral edge. The proximal point comprises a shortened angle and a fully radiused edge relative to a remaining portion of the peripheral edge and a relief recess is disposed on a distal end of the proximal base, both for the purpose of minimizing tissue snagging.
