    摘要： An apparatus for mechanically manipulating hollow organs within the body of a subject, or an organ manipulation apparatus, includes a manipulation section. The manipulation section may include a substantially two-dimensional element, which may have a width that exceeds a distance across a portion of the interior of a hollow organ within which the manipulation section is to be positioned. The manipulation section is configured to manipulate at least a portion of a hollow organ from within, which may modify at least one of a shape, orientation, or location of at least part of the hollow organ. Methods for manipulating hollow organs are also disclosed, as are operating techniques, such as left atrial ablation, in which the shapes, orientations, and/or locations of hollow organs are manipulated to move the hollow organs away from the site of the medical procedure, reducing the potential for damage to the hollow organs.

    摘要： An electrical lead including a conductor assembly, an electrode, and a thermally sensitive material. The conductor assembly has one or more conductors. The electrode is in electrical communication with one of the conductors and has an outer contact adapted for contacting adjacent body tissue of a patient. The thermally sensitive material is electrically connected between the one conductor and the electrode outer contact, and is configured to exhibit high impedance in the presence of currents considered unsafe to the patient, thereby preventing the unsafe currents from flowing through the thermally sensitive material and through the electrode outer contact potentially causing the adjacent body tissue to increase in temperature to an unsafe level. The unsafe currents cause the thermally sensitive material to increase in temperature, thereby causing the material to transition to a high impedance state.

    摘要： A lead includes a conductor having a distal end and a proximal end and a resonant circuit connected to the conductor. The resonant circuit has a resonance frequency approximately equal to an excitation signal's frequency of a magnetic resonance imaging scanner or a resonance frequency not tuned to an excitation signal's frequency of a magnetic resonance imaging scanner so as to reduce the current flow through a tissue area, thereby reducing tissue damage. The resonant circuit may be included in an adapter that provides an electrical bridge between a lead a medical device such as an electrode, sensor, or signal generator. The resonant circuit may also be included directly in the housing of a medical device.

    摘要： Medical devices that are coated with an echogenic material that includes an electrically insulativc base layer and an echogenic layer demonstrate both improved ultrasonic imaging and protection against RF electrical breakdown. The echogenic layer includes a polymeric matrix that (i) defines a plurality of void spaces, (ii) includes glass microsphere particles, or (iii) both defines a plurality of void spaces and includes glass microsphere particles. Medical instruments exhibit enhanced ultrasonic imaging even when viewed along their lengths.
