The present invention provides for therapeutic treatment methods, devices, and systems for the partial or complete closure or occlusion of a patent foramen ovale ('PFO'). In particular, various methods, devices, and systems for joining or welding tissues, in order to therapeutically close a PFO are described. In yet another aspect of the invention, various methods, devices, and systems for the penetration of the interatrial septum enabling left atrial access are also provided.

Transseptal closure of a patent foramen ovale and other cardiac defects

A PMR catheter and associated methods are disclosed. A catheter in accordance with the present invention comprised, an elongate shaft having a proximal portion, a distal portion, and a lumen extending through at least the distal portion thereof, an electrode disposed proximate the distal portion of the elongate shaft, and an electrode lumen defined by the electrode and being in fluid communication with the lumen of the elongate shaft.

PMR catheter and associated methods

A steerable guide wire and associated methods are disclosed. A guidewire in accordance with the present invention includes a shaft assembly including a lumen defined by a coil and an elongate shaft disposed within the lumen defined by the coil, a distal end of the coil being fixed to the elongate shaft proximate a distal end thereof, the elongate shaft including a curved portion proximate the distal end thereof, wherein the curved portion of the elongate shaft is biased to assume a substantially curved shape.

Steerable guidewire

Devices and methods for performing percutaneous myocardial revascularization (PMR). A catheter in accordance with the invention includes an elongate shaft having a proximal end and a distal end. The elongate shaft defines a lumen, and a conductor is disposed inside the lumen. An electrode portion is formed by the bent portion of the conductor which extends from the distal end of the elongate shaft. A method in accordance with the present invention may be used to form a wound through the endocardium and into the myocardium of a patient's heart. Collateral damage to the myocardium may be created by infusing pressurized fluid into the wound. A number of fluids may be delivered to a location proximate the wound via the catheter.
