  • Patent number: 7628802
    Abstract: A stent is constructed using interconnected links having micro-mechanical latching mechanisms. The micro-mechanical latching elements allow relative rotational movement of interconnected links in one rotational direction but restrict relative rotational movement of the two links in the opposite direction. The micro-mechanical latch surface features are formed using micro-electronic mechanical systems (MEMS) manufacturing methods. The male surface of the latching components contains an array of ridges or protrusions, and the receiving surface contains a matching array of recesses. The array of ridges or protrusions and the corresponding recesses have uniformly dissimilar slopes that result in a substantially greater frictional force in one direction than in the opposite direction. The separation distance between the two surfaces is such that the male latch surface is engaged with the receiving surface recesses in the low stress “locked” state, preventing motion in the undesired direction.

  • Patent number: 7618363
    Abstract: A ventricular assist device comprises a sheet of hydraulically actuated material that can be affixed to prescribed locations on the surface of the heart to assist areas of the heart that do not contract normally. The material is comprised of a network of contractible unit cells that individually contract when fluid is pumped into them. These unit cells are connected together in a network that causes the sheet to contract radially inward. This contraction causes the sheet to transmit forces to the heart to assist in its natural contraction. A sensing function coordinates the contraction of the sheet with the contraction of the heart. The change in shape of the device is accomplished by distributing pressurized fluid throughout the spaces of the device by way of a network of channels. When pressure is removed from the fluid system, it assumes a deenergized “rest” position in which it does not transmit any forces to the surface of the heart.

  • Publication number: 20090030291
    Abstract: A wireless sensor for indicating a physical state within an environment includes a unitary housing defining a cavity. A structure located within the cavity of the housing has elements providing capacitance, the elements being arranged such that the distance and thereby the capacitance of the structure changes when a physical state of the environment changes. The structure has a resonant frequency based at least in part on the capacitance of the structure when in the presence of a fluctuating electromagnetic field. When the sensor is positioned within an environment and is subjected to a fluctuating electromagnetic field, the resonant frequency indicates the physical state of the environment.

  • Publication number: 20080027570
    Abstract: Scoring a board configuration for a territory board game is often not straightforward and yet there is a desire to determine such scores quickly and accurately. For example, in the game of GO, determining the score at the end of the game involves assessing whether stones on the board are alive or dead which is a difficult judgment. Given a board configuration, the game is played by a scoring system to obtain a terminal board configuration. This is repeated to obtain a plurality of terminal board configurations from which an assessment can be made as to how likely each board position is to be won by a particular player at the end of the game. The scoring system obtains the terminal board configurations by playing random moves or by making a biased sampling of moves. The biased sampling is made using an evaluation function or in any suitable way. In the game of GO, seki positions are quickly and easily identified.

  • Publication number: 20080004096
    Abstract: We describe an apparatus for learning to predict moves in games such as chess, Go and the like, from historical game records. We obtain a probability distribution over legal moves in a given board configuration. This enables us to provide an automated game playing system, a training tool for players and a move selector/sorter for input to a game tree search system. We use a pattern extraction system to select patterns from historical game records. Our learning algorithm learns a distribution over the values of a move given a board position based on local pattern context. In another embodiment we use an Independent Bernoulli model whereby we assume each moved is played independently of other available moves.

  • Publication number: 20070282210
    Abstract: A method and apparatus for determining cardiac parameters within the body of a patient includes a wireless sensor positioned in the patient's pulmonary artery. An external RF telemetry device communicates wirelessly with the sensor and interrogates the sensor to determine changes in pressure in the pulmonary artery over time. The peak pressure difference is determined. Then, assuming zero blood flow velocity at the time of valve opening and at the time of valve closing, a velocity-time function is determined. The velocity-time function is used to determine a velocity-time integral. The velocity-time integral is then used to determine cardiac stroke volume. The cardiac stroke volume is multiplied times the heartbeat rate to determine cardiac output. The cardiac output can be monitored over time to determine continuous cardiac output.

  • Publication number: 20070270934
    Abstract: An implant assembly for releasing into a vessel at an implant location includes an intracorporeal device and an anchor. The anchor comprises a pair of resiliently deformable loops operatively associated with the intracorporeal device, both of the loops extending toward the same side of a plane defined by the intracorporeal device. The deformable loops have a relaxed state and a deformed state. When the deformable loops are in a relaxed state, the implant assembly has a major dimension in a direction out of the plane that is greater than the diameter of a vessel at the implant location. The loops are deformable to permit insertion of the implant assembly into the vessel. The tendency of the loops to return to their relaxed state exerts a force on a wall of the vessel that imposes the intracorporeal device against an opposite wall of the vessel.
