A device for creating a surgical perforation with a functional distal tip for creating a controlled perforation. The functional tip may comprise at least one active electrode for creating the perforation through the application of Radio Frequency (RF) energy. The device is curved in order to decrease the likelihood of injury to structures of a patient such as inadvertent cardiac perforation when used in transseptal perforation procedures. The device is introduced into the right atrium, and the functional tip is then positioned against the atrial septum. Energy is applied to create the perforation. The tip is advanced toward the left atrium to create the perforation and as it advances into the left atrium, the device takes on its curved shape to direct the tip away from cardiac structures. The position of the tip of the device can be determined in response to pressure sensed at the tip and determined by a monitor.

A feeding fence section (1, 1′) suitable for separating a feeding area (4) for animals and a feed-holding part (5) is disclosed, where the feeding fence section (1, 1′) is provided with flexible mounting means (2), which allows the fence section (1, 1′) to be angularly displaced by said animals from a starting position (1) towards a tilted position (1′) about a substantially horizontal, longitudinal axis, wherein the mounting means (2) are biasing the fence section from said tilted position (1′) towards the starting position (1).

The invention relates to the technical field of mechanical mounting equipment and discloses a blind pin puller. The blind pin puller comprises a front pull rod, a chuck and a center screw. A through hole is formed in the middle of the front pull rod, the lower end of the front pull rod is a counter bore, the end part of the counter bore in the lower end is a cone-shaped horn mouth, the upper end of the front pull rod is a counter bore, the upper end of the chuck is a cone-shaped head, the lower end of the cylinder body of which is big on the lower side but small on the upper side, the upper end of the chuck is a screw hole while the lower end of the chuck is a pin pulling hole, an open slot is formed from a hole arm of the pin pulling hole to the lower end, the cone-shaped face of the cone-shaped head of the chuck is matched with the cone-shaped horn mouth of the front pull rod when the chuck is matched in the counter bore in the lower end, a distance is formed between the front end ofthe chuck and the bottom of the counter bore in the lower end of the front pull rod, the center screw is formed in the middle through hole of the front pull rod, the thread at the lower end of the center screw is matched with a screw hole in the upper end of the chuck, and the head of the center screw is located in the counter bore in the upper end of the front pull rod. The blind pin puller provided by the invention is simple and feasible and convenient to operate, and does not damage a product body and a pin in the pin pulling process.

A specimen container system and methods of use are described herein for capturing, storing and accessing fluids for lab testing. A cup is removably secured to a cap assembly. The cap assembly is comprised of cover and a lid which are connected by a hinge assembly having a biasing member for maintain the lid in an open position. An aperture in the cap has two sections that in combination with the lid decreases the contamination risk compared to prior art container system.

A mixer wagon includes a mixing chamber having a bottom, a fill opening larger than the bottom, and a wall. A work tool is provided in the mixing chamber for sweeping over a work area on the bottom. The wall is provided at its side with a flattening defined by curved portions, the flattening having assigned thereto a discharge opening which is closable by a slide. The flattening encloses with the mixing chamber bottom a first inclination angle that is smaller than a second inclination angle enclosed by the curved portion with the bottom. A comfortable lateral discharge of the fodder is combined with a thorough mixing by providing that in the vicinity of the bottom the slide and the curved portion of the wall on the discharge opening follows the shape of the circumference of the work area, and the opening and closing path P extend at an angle that is substantially equal to or larger than the larger inclination angle.
