Abstract: A catheter system includes a catheter and a control system. The catheter includes an elongate catheter body and a catheter tip coupled to a distal end of the elongate catheter body. The catheter tip includes a plurality of openings corresponding to a plurality of lumens extending through the elongate catheter body. The control system is configured to initiate a source of vacuum pressure to at least one of the plurality of lumens, receive an indication of a vacuum seal, and in response to the indication of the vacuum seal, initiate a source of ablation energy.
