摘要：
A medical system for introduction through a septum separating a first heart chamber from a second heart chamber includes a guide catheter with a distal segment and a guide catheter lumen adapted to receive a mapping/ablation catheter. The guide catheter includes a deployable retention mechanism that engages the septum and inhibits advancement or retraction of the guide catheter through the septum. The system also includes an ablation device for delivering ablation energy to tissue. The ablation device is positioned in a heart chamber via the guide catheter lumen.
