Abstract: An ablation catheter having a catheter shaft and a virtual electrode, the virtual electrode comprising portholes through an outer peripheral wall of the catheter shaft and a metal electrode, the catheter being used for treatment of cardiac arrhythmia, for example, atrial fibrillation, by electrically isolating a vessel, such as a pulmonary vein, from a chamber, such as the left atrium. The catheter shaft includes a proximal portion and a distal portion. The distal portion includes an active region, which is either a looped structure transverse to the longitudinal axis of the catheter shaft, or a linear structure that extends parallel to the longitudinal axis of the catheter shaft. During use, the active region is directed into contact with, for example, the wall of a pulmonary vein. Upon energization, the virtual electrode creates a continuous lesion on an inner wall of the pulmonary vein, thereby electrically isolating the pulmonary vein from the left atrium.

Abstract: A membrane actuator includes a magnetically actuatable membrane and a magnetic trigger. The membrane includes a shape memory alloy (SMA), and the magnetic trigger is configured to induce a martensitic transformation in the SMA, to produce a larger force than would be achievable with non-SMA-based materials. Such a membrane actuator can be beneficially incorporated into a wide variety of devices, including fluid pumps, shock absorbing systems, and synthetic jet producing devices for use in an aircraft. The membrane/diaphragm can be formed from a ferromagnetic SMA, or a ferromagnetic material can be coupled with an SMA such that the SMA and the ferromagnetic material move together. A hybrid magnetic trigger, including a permanent magnet and an electromagnet, is preferably used for the magnetic trigger, as hybrid magnetic triggers are easy to control, and produce larger magnetic gradients than permanent magnets or electromagnets alone.

Abstract: A catheter used for diagnosing and treating, for example, atrial fibrillation. The catheter includes a catheter shaft that has a proximal portion and a distal portion. The distal portion is adapted to be inserted into a body cavity having tissue to be diagnosed or treated and is disposed remotely from the proximal portion. The distal portion, which may be curved or straight, comprises an outer peripheral wall having an active region, and the distal portion has a cross-sectional configuration along the active region. The cross-sectional configuration is adapted to bias the active region against the tissue to be diagnosed or treated.

Abstract: Accessing interior compartments for storage or other purposes is improved by the use of one or more active material components. Activating one or more active material components carries out one or more of the following functions: opening or closing the compartment (which may include cinching a closure) and/or latching or unlatching a closure from a frame. Activation may result from a remote trigger signal. A method is provided for controlling access to an interior compartment that may be carried out by a controller operatively connected to various active material components that unlatch the closure from the frame, close the closure and cinch the closure to the frame, respectively.

Abstract: Methods and apparatus for treatment of anatomic defects in human tissues, such as patent foramen ovale (PFO), atrial or ventricular septal defects, left atrial appendage, patent ductus arteriosis, blood vessel wall defects and certain electrophysiological defects, involve positioning a distal end of an elongate catheter device at the site of the anatomic defect, engaging tissues at the site of the anatomic defect to bring the tissues together, and applying energy to the tissues with the catheter device to substantially close the anatomic defect acutely. Apparatus generally includes an elongate catheter having a proximal end and a distal end, a vacuum application member coupled with the distal end for engaging tissues at the site of the anatomic defect and applying vacuum to the tissues to bring them together, and at least one energy transmission member coupled with the vacuum application member for applying energy to tissues at the site of the anatomic defect to substantially close the defect acutely.
