Stent delivery catheter

The present invention provides a stent delivery catheter that can place a stent in a tortuous narrowed area with good maneuverability while preventing falling or displacement of the stent. The present invention provides a stent delivery catheter for delivering a stent for treating stenosis in a body to a narrowed area. A distal end of the catheter includes a collapsible balloon in a collapsed state and the stent in an undeployed state, the stent being mounted on the outer surface of the collapsed balloon, the balloon having frustoconical tapered segments and a cylindrical straight tubular segment. An inner tube for defining a guidewire lumen extends into the interior of the balloon, and displacement prevention mechanisms for preventing the stent from moving in the longitudinal direction of the stent delivery catheter are affixed to the inner surface of the balloon only. Another aspect of the present invention provides a stent delivery catheter that can prevent the stent from moving in the axis direction of the catheter without requiring additional components or additional steps that complicate the manufacturing process. In this catheter, the thickness T1 of a near-center portion of the distal-end tapered segment and the thickness T2 of a near-center portion of the straight tubular segment satisfy a predetermined relationship, and the thickness T3 of a near-center portion of the proximal-end tapered segment and the thickness T2 of the near-center portion of the straight tubular segment satisfy a predetermined relationship. In this manner, the distal-end and proximal-end tapered segments in the collapsed state prevent the movement of the stent. The present invention also provides a preferable RX balloon catheter, i.e., a stent delivery catheter, having improved maneuverability and enhanced responsiveness for expansion and contraction of the balloon without complicating the manufacturing process or increasing the cost.

Window control method

InactiveUS20050060658A1Maximized and minimizedIncreased and reduced in sizeCathode-ray tube indicatorsInput/output processes for data processingComputer scienceComputer hardware
A method allows a window to be enlarged, reduced in size, or moved easily by designating an operated object without performing an operation of accurately positioning a point position at a frame line or vertex as the operated object. The method comprises a step of sequentially acquiring the position of a pointer of said pointer device as said pointer is moved after the movement trajectory of said pointer intersects itself following the start of a pointer moving operation, until said pointer moving operation is completed, and storing the thus acquired positions in a table; a step in which it is determined if a part of the movement trajectory of said pointer that is obtained by connecting the information about the movement positions of said pointer stored in said table intersects any of the frame lines of the window as a controlled object, and if it does, the following factors: a. the number of intersected frame lines of the window; and b. the number of end-point coordinates of the intersected frame lines, in order to determine the movement trajectory of said pointer corresponds to which of the instructions of the enlargement / reduction and movement of the window frame, and the window frame or a vertex is determined as the object of operation; and a step of enlarging, reducing, or moving the window frame or vertex as the object of operation in accordance with the thus recognized instruction, in a positional direction in which the movement operation of said pointer has ended after the movement trajectory of said pointer intersected itself, until the completion of the movement operation, by moving the window frame or vertex in accordance with the amount of movement of said pointer.

INTEGRATED PROPULSION & STEERING For Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), Fuel Cell Electric Vehicles (FCEV), AV (Autonomous Vehicles); Electric Trucks, Buses and Semi-Trailers

A vehicle, integrated all-wheel propulsion and steering system with plurality of propulsion and steering power sources, designed with enumerate specifications are coupled to, and de-coupled from a final drive of the vehicle propulsion system. A controller receives input-signals from the driver steering-wheel sensor; computes a set of reactions to the plurality of steering-actuators, wherein feedback-mechanism with each wheel-position sensor, the controller secures each wheel in its computed angle. In different speed and load conditions, the controller is programmed to compute a desired power demand then couple to the final drive[s] the propulsion power source[s] that is designed to do-the-job with the least energy consumption. When the vehicle changes speed and load, the controller couples a different power source[s], and de-couples the previous power source[s] to meet the power demand. In turning-modes, whilst positioning every wheel in its computed position, the controller computes the different distances the left and the right wheels of the vehicle have to travel, wherein the controller moves-up the propulsion power sources velocity to the wheels opposite to the turn to make a perfect turn without EPS assistance.
