More Information
Summary:A transseptal access system is disclosed. The system includes a radiofrequency perforation device having a proximal portion and a distal portion. The proximal portion has an electrically insulated outer surface, the distal portion is electrically conductive and terminates at a functional tip, and at least part of the distal portion is uninsulated. A tubular dilator is further disclosed comprising an elongated body terminating in a distal tip, a hub at the proximal end of the body, and a dilator lumen extending through the hub and the body. The dilator lumen is dimensioned to slidingly receive the radiofrequency perforation device. An electrical contact element disposed within the hub adjacent to the dilator lumen is also disclosed. When the radiofrequency perforation device is in a first position within the dilator lumen, the electrical contact element is in electrical engagement with the distal portion of the radiofrequency perforation device.
