| 20100174231 | METHOD FOR PHYSIOLOGIC CONTROL OF A CONTINUOUS FLOW TOTAL ARTIFICIAL HEART - A method is provided of controlling a pump including a electrical motor coupled to a rotor which carries first and second impellers at opposite ends thereof. The method includes: (a) driving the rotor using the motor, so as to circulate fluid from the first impeller through a first fluid circuit, the second impeller, a second fluid circuit, and back to the first impeller; (b) determining a resistance of the first fluid circuit, based on a first motor parameter; (c) determining a flow rate through the first fluid circuit based on a second motor parameter; and (d) varying at least one operational parameter of the pump so as to maintain a predetermined relationship between the flow rate and the resistance of the first fluid circuit. | 07-08-2010 |

| 20080287795 | System And Method For Identifying A Vascular Border - A system and method is provided for using a first vascular image, or more particularly a plurality of control points located thereon, to identify a border on a second vascular image. Embodiments of the present invention operate in accordance with an intra-vascular ultrasound (IVUS) device and a computing device electrically connected thereto. Specifically, in one embodiment of the present invention, an-IVUS console is electrically connected to a computing device and adapted to acquire IVUS data. The IVUS data (or multiple sets thereof) is then provided to (or acquired by) the computing device. In one embodiment of the present invention, the computing device includes a plurality of applications operating thereon—i.e., a border-detection application, an extrapolation application, and an active-contour application. These applications are used to (i) identify a border and control points on a first IVUS image (i.e., any IVUS image), (ii) extrapolate the control points to a second IVUS image (i.e., another IVUS image), (iii) identify a border on the second IVUS image, and (iv) adjust the border on the second IVUS image in accordance with at least one factor. In one embodiment of the present invention, the at least one factor is selected from a group consisting of gradient factor, continuity factor, and curvature factor. | 11-20-2008 |
| 20100174233 | VASCULAR GUIDEWIRE SYSTEM AND METHOD - A vascular guidewire system includes a tubular member which at least partially encloses a core wire. A first or distal gripper is connected with a handle to grip a proximal end portion of the tubular member. A second or proximal gripper is disposed in the handle and grips a proximal end portion of the core wire. A first or distal motor is disposed in the handle and is operable to rotate the core wire relative to the outer tubular member. A second or proximal motor is disposed in the handle and is operable to move the first or distal motor longitudinally relative to the handle to thereby move the core wire longitudinally relative to the outer tubular member. The second or proximal motor is disposed in a coaxial relationship with the first or distal motor. Rotational and/or longitudinally directed forces may be manually applied to the handle to move the tubular member and core wire relative to a patient's body. | 07-08-2010 |
| 20110087101 | System and Method for Determining a Transfer Function - A system and method is provided for using ultrasound data backscattered from vascular tissue to estimate the transfer function of a catheter (including components attached thereto—e.g., IVUS console, transducer, etc.). Specifically, in accordance with a first embodiment of the present invention, a computing device is electrically connected to a catheter and used to acquire RF backscattered data from a vascular structure (e.g., a blood vessel, etc.). The backscattered ultrasound data is then used, together with an algorithm, to estimate the transfer function. The transfer function can then be used (at least in a preferred embodiment) to calculate response data for the vascular tissue (i.e., the tissue component of the backscattered ultrasound data). In a second embodiment of the present invention, an IVUS console is electrically connected to a catheter and a computing device and is used to acquire RF backscattered data from a vascular structure. The backscattered data is then transmitted to the computing device, where it is used to estimate the catheter's transfer function and to calculate response data for the vascular tissue. The response data and histology data are then used to characterize at least a portion of the vascular tissue (e.g., identify tissue type, etc.). | 04-14-2011 |

| 20100133098 | Methods and Devices for Concentration and Purification of Analytes for Chemical Analysis Including Matrix-Assisted Laser Desportion/Ionization (MALDI) Mass Spectrometry (MS) - Analytical methods and devices are disclosed for separating low abundance analytes by electrophoretically driving the analytes through a sieving matrix to first remove high molecular weight species. Subsequently the remaining low abundance analytes are electrophoretically focused onto a capture membrane where the analytes become bound within a small capture site. After this step the capture membrane may be allowed to dry and then attached to a conductive MALDI sample plate. | 06-03-2010 |

| 20110007129 | OMNIVIEW MOTIONLESS CAMERA ORIENTATION SYSTEM - An apparatus and method is provided for converting digital images for use in an imaging system. The apparatus includes a data memory which stores digital data representing an image having a circular or spherical field of view such as an image captured by a fish-eye lens, a control input for receiving a signal for selecting a portion of the image, and a converter responsive to the control input for converting digital data corresponding to the selected portion into digital data representing a planar image for subsequent display. Various methods include the steps of storing digital data representing an image having a circular or spherical field of view, selecting a portion of the image, and converting the stored digital data corresponding to the selected portion into digital data representing a planar image for subsequent display. In various embodiments, the data converter and data conversion step may use an orthogonal set of transformation algorithms. | 01-13-2011 |
