Abstract: A thrust recovery outflow valve and method for controlling the transfer of air between a cabin in an aircraft and atmosphere outside of the aircraft are provided. An outflow valve is mounted on the aircraft that includes a valve frame, a first valve door, and a second valve door. The first valve door is rotated to a first predetermined open position while the second valve door is in the second door closed position to thereby open first and second flow passages that place the aircraft cabin in fluid communication with the atmosphere. When the first valve door is at a first predetermined open position, a flap is rotated, relative to the first valve door, to at least partially cover the second flow passage and thereby at least inhibit flow through the second flow passage.

Abstract: Methods and apparatus for providing transapical access to a heart chamber for performing an intra cardiac procedure are described. The apparatus include a helical needle driver, a dilator, a straight access needle, and optionally a guidewire. After entering the heart chamber with the straight access needle, the helical needle driver is used to place a helical suture within the myocardium. After removing the needle driver, the dilator is advanced through the pre-placed helical suture, dilating both a passage and the circumscribing suture. After performing procedure, the pre-placed suture may be closed by proximally retracting an external end of the suture.

Abstract: An open ear clamp having a clamping device like a so-called Oetiker ear. To make the installation of the clamp on a pipe easier, the clamp is pre-deformed, for example, in the course of production, to such an extent that the clamp surrounds the pipe for which the clamp is intended without play. Because of the elasticity produced in the clamp by this pre-deformation, the clamp still can be moved effortlessly to the installation location on the pipe and yet is retained there in the position of the clamp and in the desired orientation.
