1. A suction clip system configured for marking or hemostatic treatment of tissue, the suction clip system comprising:
- an elongate delivery catheter having a delivery lumen disposed between a proximal delivery catheter end and a distal delivery catheter end, wherein the distal delivery catheter delivery end comprises an enlarged lumen portion defining an enlarged lumenal space;
an elongate suction catheter slidably disposed through at least a portion of the delivery lumen, the suction catheter including a suction lumen disposed between a proximal suction catheter end and a distal suction catheter end; and
a suction clip member at least partially removably disposed in the delivery lumen and comprisinga distal suction chamber portion including a distal lip configured to conform to a body tissue surface, wherein the distal suction chamber portion is disposed in the enlarged lumenal space of the delivery catheter;
an intermediate portion comprising a check valve; and
a proximal portion configured for connection with a vacuum source; and
wherein the distal suction chamber portion is in fluid communication with the suction lumen when the check valve is in an open state.
