Elastomeric balloon support fabric
InactiveCN1494441ANo significant reduction in flexibilityEasy to control follow-upStentsBalloon catheterElastomerYarn
Balloon catheter covers are elastic fabric structures of interconnected yarns, the structure having a high degree of stretch and recovery in the circumferential direction with little change in dimension in the longitudinal direction during multiple pressurization cycles over full range of inflation and deflation of the balloon catheter. The covers have longitudinal yarns positioned at about zero degrees to the balloon axis and reversibly-stretchable, circumferential yarns positioned at a high angle O to the axis. A method for making the balloon catheter covers allowing nearly orthogonal placement of circumferential and longitudinal yarns involves triaxial braiding a minimum number of elastomeric braid yarns with multiple axial yarns to provide maximum convergence angle (approaching 90 degrees).

The invention discloses a detection method for detecting a blocked or unlocked state of a parking brake member comprising a bistable linear electromagnet (1). The parking brake member being connectedboth to a power supply assembly (14) arranged to generate a control voltage (Uc) and to a current sensor (15) arranged to measure a control current (Ic), the control voltage (Uc) being greater than the control current (Ic). The detection method comprises the steps: controlling the power supply assembly (14) to generate a test voltage (Utest) across the terminals of the coil and thus a test current(Itest) flowing in the coil, the test voltage having an amplitude less than a predetermined voltage threshold such that a test magnetic field generated by the test current does not shuttle; acquiringa measurement of the test current as generated by the current sensor (15); and analyzing the measurement of the test current and detecting a blocked or unlocked state of the parking brake member based on this analysis.
