The invention provides a medical device having a catheter and one or more expandable constricting/occluding members. The catheter is adapted for use with therapeutic or diagnostic devices, including an angioplasty/stent catheter and an atherectomy catheter. The constrictor/occluder is mounted at the distal end of the catheter. Manometers may be mounted distal to one or more constrictors for measuring pressure distal to the constrictor(s). Methods of using the devices for preventing distal embolization during extracranial or intracranial carotid procedures or vertebral artery procedures by reversing blood flow in an internal carotid artery, an external carotid artery, and/or a common carotid artery toward the subclavian artery are disclosed.

Methods and apparatus for treatment of layered tissue defects such as a patent foramen ovale provide for applying energy to tissues adjacent to the PFO with a closure device that substantially closes the PFO. Apparatus generally includes an elongate flexible member having a proximal end and a distal end and an energy transmission member deployable from the elongate flexible member. The energy transmission member applies energy to the layered tissue defect at a first position and a second position adjacent to the first position so as to substantially close the layered tissue defect along at least a portion of the defect. Applied energy may be monopolar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating, direct heat energy, cryogenic or the like. PFO closure via energy-based approaches of the invention may help prevent stroke, treat migraine headache, and possibly treat or prevent other medical conditions.

The invention provides a medical device having a catheter and first and second expandable members. The device may be used for protection against stroke by inserting the catheter into a carotid artery, locating the first expandable member within a common carotid artery, locating the second expandable member within an external carotid artery, expanding the first expandable member to occlude the common carotid artery, and expanding the second expandable member to at least partially obstruct the external carotid artery. By this method antegrade blood flow in the internal carotid artery stops.

Methods and apparatus for treatment of patent foramen ovale (PFO) provide for applying energy to tissues adjacent the PFO with a catheter device to substantially close the PFO acutely. Apparatus generally includes a catheter device having at least one energy transmission member at or near its distal end configured to apply energy to PFO tissues to acutely, substantially close the PFO. Applied energy may be monoploar or bipolar radiofrequency energy or any other suitable energy, such as laser, microwave, ultrasound, resistive heating or the like. Some embodiments of a catheter device further include one or more tissue apposition members near the distal end for helping bring PFO tissues together, such as a PFO covering member, a vacuum applying member and/or the like. PFO closure via energy-based approaches of the invention may help prevent stroke, treat migraine headache, and possibly treat or prevent other medical conditions.
