  • METHOD FOR MANUFACTURING A BENDABLE TUBE
    Publication number: 20100287755
    Abstract: With a method for manufacturing a bendable tube, which is preferably envisaged for an endoscopic instrument, first a tube is separated into several tube sections in a manner such that adjacent tube sections engage into one another with a positive fit in the axis direction of the tube. After the separation of the tube into several tube sections, one envisages peripherally arranging means for providing a positive fit transversely to the axis direction of the tube, on the regions of the tube sections, which are situated in engagement with one another.

  • SYRINGE, IN PARTICULAR FOR VETERINARY-MEDICINE APPLICATIONS
    Publication number: 20100081999
    Abstract: A syringe for veterinary-medicine applications has a main body with a syringe cylinder whose discharge-side end is connected to a cannula and in which a piston connected to a piston rod is situated so it is displaceable. The syringe includes a protective module including protective cap and a securing element. The protective cap is mounted so it is displaceable on the main body, which receives the cannula in its first terminal position so that the front end thereof does not protrude from the protective cap. The securing element can be moved from a first securing position into a second securing position and then into a third securing position. The securing element releases a locking of the piston rod relative to displacements, so that the piston can be moved in the syringe cylinder in the direction toward the discharge-side end using the piston rod.

  • Method for effecting local increases in temperature inside materials, particularly body tissue
    Patent number: 7645235
    Abstract: Local tissue areas should be thermally destroyed when using ultrasound thermotherapy. Traditionally, mono-frequency continuous wave ultrasound signals are used to this end. These lead to a non-optimal distribution of heat or to a non-optimal localization of the heating inside the tissue. In practice, the following dosage problem arises: the prevention of unwanted tissue damage in the tissue located in front of the target area while simultaneously having a sufficiently high damaging effect in the target area. The aim of the invention is to optimize the distribution of heat or to increase the localization of the heating. To these ends, modified transmitted signals (e.g. multi-frequency signals) are used that are adapted to a specific utilization of the non-linear ultrasound propagation and attenuation properties inside the tissue.
