Method and device for transseptal facilitation using location system

摘要

A method for performing a procedure at the fossa ovalis (107) in the septal wall of the heart includes the steps of identifying the septal wall (105) of the heart (100); identifying the fossa ovalis in the septal wall; tagging a point at the fossa ovalis; providing a sheath (120) having a body (120a) wherein the body has a lumen extending therethrough and an open end at a distal end (126) of the body. The body also has a position sensor (128) at the distal end of the body wherein the position sensor generates signals indicative of a location of the distal end of the body. The sheath is navigated to the fossa ovalis at the tagged point using the position sensor. The fossa ovalis is punctured at the tagged point using a penetrating device.
