  • Nitric oxide donors and uses thereof
    Patent number: 7968575
    Abstract: Disclosed are novel NO-donating compounds, designed such that when NO is released from the compound a residue which is a naturally occurring metabolite is formed, and thus a development of tolerance to the compounds upon repetitive administration is prevented or decreased. Also disclosed are methods of preparing such NO-donating compounds, pharmaceutical compositions and medical devices containing such compounds and methods utilizing such compounds in the treatment of various medical conditions.

  • Method and device for wireless communication using MIMO techniques
    Patent number: 7970355
    Abstract: The present invention describes a method of closed loop MIMO communication utilizing implicit or explicit channel state information (CSI) at the transmitter and the receiver. The transmitter performs linear pre-processing (for example, QR decomposition or bi-diagonal decomposition or Jacobi rotations, and/or sporadic SVDs) on a channel matrix, and the receiver mitigates the mutual interference between the streams by performing MMSE processing on the received signals. The MMSE matrix is computed with respect to the processed channel that may estimated by the receiver through preprocessed pilot signals. The transmitters preprocessing is of much lesser cost and complexity than full SVD.

  • SENSING CONTACT OF ABLATION CATHETER USING DIFFERENTIAL TEMPERATURE MEASUREMENTS
    Publication number: 20110152854
    Abstract: Tissue ablation is carried out using insertion tube having at least one ablation electrode, a first temperature sensor disposed on the distal portion sufficiently proximate the ablation electrode to detect heat generated during the ablation procedure, a second temperature sensor disposed on the distal portion sufficiently distant from the ablation electrode to be unable to detect the heat, and electronic logic circuitry linked to the first temperature sensor and the second temperature sensor and programmed to compute a temperature differential between respective temperatures sensed by the first temperature sensor and the second temperature sensor when conveying the electromagnetic energy. Satisfactory contact status between the ablation electrode and the target tissue is indicated when the temperature differential exceeds a predetermined threshold.

  • ESTIMATION AND MAPPING OF ABLATION VOLUME
    Publication number: 20110152856
    Abstract: Tissue ablation systems and methods are provided, wherein a cardiac catheter incorporates a pressure detector for sensing a mechanical force against the distal tip when engaging an ablation site. Responsively to the pressure detector, a controller computes an ablation volume according to relationships between the contact pressure against the site, the power output of an ablator, and the energy application time. A monitor displays a map of the heart which includes a visual indication of the computed ablation volume. The monitor may dynamically display the progress of the ablation by varying the visual indication.

  • Model-based correction of position measurements
    Patent number: 7962195
    Abstract: Visualization of a probe when impedance-based measurement technology is being used is improved by stabilizing a displayed image of the probe or catheter. Using a model of reasonable probe shapes and a matching algorithm, an erroneous probe image is adjusted so that it assumes a realistic shape on a display. A range of positional variations is also incorporated in the model. When an apparent probe position exceeds a permissible range of motion, the probe image is constrained to a realistic position.
