  • Patent number: 7497858
    Abstract: An instrument assesses the transmurality of an ablation lesion from a first surface of a targeted biological tissue to an opposed second surface thereof. The instrument includes at least a first electrode operably attached to an ablation instrument adapted to engage a tissue first surface, and at least a second electrode adapted to engage a tissue second surface, the at least second electrode positioned generally opposed to the at least first electrode. Alternatively, the at least second electrode may be adapted to be placed within a chamber of an organ. These electrodes facilitate measuring at least one of conduction time, conduction velocity, phase angle, and impedance through at least a portion of the targeted tissue to determine the transmurality of the ablation lesion.

  • Publication number: 20080071259
    Abstract: A flexible microwave antenna assembly for a surgical ablation instrument capable of conforming to a tissue surface for ablation thereof. The ablation instrument includes a transmission line having a proximal portion suitable for connection to an electromagnetic energy source. The antenna assembly includes a flexible antenna coupled to the transmission line for radially generating an electric field sufficiently strong to cause tissue ablation. A flexible shield device is coupled to the antenna to substantially shield a surrounding area of the antenna from the electric field radially generated therefrom while permitting a majority of the field to be directed generally in a predetermined direction. A flexible insulator is disposed between the shield device and the antenna which defines a window portion enabling the transmission of the directed electric field in the predetermined direction.

  • Patent number: 7346930
    Abstract: The present disclosure is a method for bridging requests for access to resources between requesters in a distributed network and an authenticator servicing the distributed network. The bridging mechanism has security features including a naming service for machine authentication and machine process rules to authorize what process machines can perform. The security proxy bridge intercepts an access request, and checks the IP address for machine authentication as well as the machine process rules and if both verifications are successful, the bridge then forwards the request for access to the authenticator. The security proxy framework utilizes a data structure that provides a method for storing selected security information stored as data records supporting an authentication and authorization system for users to access resources on multiple components of a distributed network supporting multiple business units of an enterprise.

  • Patent number: 7020159
    Abstract: Methods and systems for matching the communication protocol of a calling device with one of a plurality of communication protocols supported by an answering device are provided. Initially, a predetermined amount of data is received and buffered in a memory component. Following, an analysis is performed to match the received data with one of the communication protocols supported by the answering device. Communication protocols that can be detected and matched include, for example, the V.110, V.120 and ISDN protocols. During the buffering and analyzing steps, a predetermined data pattern such as mark idle can be transmitted to the calling device. Thereafter, the answering device is configured to answer the call according to the protocol matched in the analyzing step. A timer can be utilized to limit the period for matching to a predetermined length, after which time the answering device can be configured to answer the call in analog mode.
