摘要： An apparatus includes a body assembly, a shaft, and at least one tip member. The shaft extends distally from the body assembly and includes a distal end. The at least one tip member is secured at the distal end of the shaft. The at least one tip member and the distal end of the shaft are sized and configured to fit within a chamber of a heart of a human subject. The at least one tip member includes an atraumatic distal tip and an exterior dilation surface adjacent to the atraumatic distal tip. The atraumatic hollow distal tip may present an angled profile to minimize risk of coring tissue and is configured to deliver electrical energy to tissue for forming an opening through the tissue. The exterior dilation surface is configured to enlarge the opening formed by the atraumatic distal tip.

摘要： A catheter includes a tip electrode with a shell and a support member to provide a plenum chamber. The support member is formed with a U-shaped passage for a safety line to wrap around and secure the support member (with the shell affixed thereto) to the catheter. Additional passages are formed in the support member to accommodate components such as irrigation tubing, lead wires and a thermocouple wire pair. A method of manufacture provides distal installation and/or anchoring of the safety line, lead wire and thermocouple wire pair in the support member prior to sealing the support member and mounting the shell.

摘要： A transseptal puncture system and method uses a guiding instrument, and an atraumatic puncture instrument longitudinally movable therein, with a first electrode configured for ablation and a second electrode electrically insulated from the first electrode. An impedance monitoring module is configured to measure at least an impedance at the second electrode, and an electrical generator is configured to selectively apply electrical energy to the first electrode based at least in part on the measured impedance at the second electrode. Moreover, impedance measurements at the first and second electrodes are used to determine relative positions of the instruments in the approach, contact, ablation and puncture of the septum.
