A catheter balloon arrangement for application in tortuous blood vessels. First and second spiraled balloons are coupled to a catheter body portion. The spiraled balloons can have first and second apexes with a pitch length there between configured to encourage tortuous compatibility between the catheter balloon arrangement and a body lumen. A method of treatment with an embodiment of a catheter balloon arrangement is also provided.

Spiraled balloon arrangement for treatment of a tortuous vessel

The invention is directed to a system and method for revascularization of a patient's heart tissue by at least one burst of RF energy over an interval of about 1 to about 500 msec, preferably about 30 to about 130 msec. The device preferably has an elongated insulated, electrical conducting shaft with an uninsulated distal tip which is configured to emit RF energy. A method is described for myocardial revascularization of a human heart in which an elongated flexible device is used which includes a radiofrequency ablation device. In some embodiments, the device is configured to be introduced percutaneously, on other embodiments, the device is configured to be introduced intraoperatively. The RF energy emitter is advanced to a position adjacent a desired area of the heart wall. The device is activated, moving tissue to form a revascularization channel.

Transmyocardial revascularization using radiofrequency energy

An intravascular device for forming a channel within a patient's ventricular wall which engages the tissue of the ventricular wall to prevent undesirable movement of the channel forming device while forming the channel.

Channel forming device with a secured distal extremity

The method for intra-operative myocardial revascularization of a human heart includes a inserting a portion of an elongated flexible lasing apparatus into the chest cavity of a patient, and lasing channels from the epicardium through the myocardium of the heart, without mechanical tearing of the heart tissue. The apparatus is guided to an area exterior to a ventricle of the patient's heart, and the distal end of the optical fiber apparatus is directed to an area of interest where the exterior wall of the heart is irradiated with laser energy to form a channel through the myocardium.
