An embodiment of the invention provides a method for detecting and treating a tumor using tissue localized volumetric impedance measurement. The method includes providing an impedance measurement apparatus having a plurality of resilient members deployable with curvature and configured to sample tissue impedance through a plurality of conductive pathways. The apparatus is configured to be coupled to at least one of an energy delivery device, a power supply, a switching device or logic resources. The apparatus is then positioned at a selected tissue site and the impedance array deployed to define a sample volume. The impedance array is then utilized to make impedance measurements through a plurality of conductive pathways. Information from the impedance measurements is then utilized to determine a tissue condition of the sample volume. Energy is then delivered from the energy delivery device to ablate or necrose at least a portion of the tumor.

A method and apparatus for carrying our thermal ablation of target tissue is disclosed. The apparatus includes an RF ablation device having a multi-electrode electrode assembly designed to be deployed in target tissue, defining a selected-volume tissue region to be ablated, and having infusion channels for infusing a liquid into the target tissue during the ablation process. A control unit in the apparatus is operably connected to an RF energy source, for controlling the RF power level supplied to the electrodes, and to an infusion device, for controlling the rate of infusion of a liquid through the device into the tissue. During both electrode deployment and tissue ablation, impedance and or temperature measurements made within the tissue are used to control the RF source and infusion device, for optimizing the time and extent of tissue ablation.

A tamper-proof electronic security seal which includes a bolt and a locking element and an electronic seal element. The bolt has a head and a hollow shank extending therefrom having a longitudinal bore formed therein. The shank is dimensioned to pass through a lock hasp and has a free end formed for locking engagement with the locking element. The electronic seal element is formed for mechanical connection to the bolt head, and includes an electrical power source, a control unit, communications means responsive to the control unit and a sensor adapted for insertion into the longitudinal bore of the shank, and connected to the control unit. In response to a severing of the shank and the sensor inserted therein, the control unit is operative to activate the communications means to emit an alarm signal.

Systems and methods are provided for monitoring a subject, and particularly, for inferring an underlying brain state present in absence of current conditions. In some aspects, a method for monitoring the subject is provided including steps of receiving physiological feedback from at least one sensor configured to acquire physiological information from locations associated with a subject's brain, assembling a set of time-series data using the received physiological feedback, and identifying portions of the set of time-series data that indicate a burst suppression state. The method also includes identifying a burst characteristic profile associated with a burst pattern determined from the identified portions, and comparing the burst characteristic against a reference set of burst profiles. The method further includes determining, based on the comparison, a likelihood of a brain state of the subject underlying the burst suppression state, and generating a report indicative of the likelihood of the determined brain state.

Methods and systems for making a financial payment to a payee via a paper check utilizing a mobile device such as a mobile telephone (cellphone) or wireless connected personal digital assistant (PDA). The mobile device communicates wirelessly with a mobile financial transaction system (MFTS) that stores user information and transaction information. A user enters information via the mobile device identifying a payee and indicating a paper check payment method. The mobile device generates a mobile payment instruction that includes information corresponding to the identified payee and indicating a paper check payment method. The mobile payment instruction is wirelessly communicated to the MFTS. The MFTS generates an MFTS payment instruction to a payment instruction recipient that can issue a paper check. The MFTS communicates the MFTS payment instruction to the payment instruction recipient, which arranges for payment to the identified payee by printing and mailing of a paper check to the payee.

An apparatus for treating tumors comprises an elongated delivery device that includes a lumen and is maneuverable in tissue.
