    Abstract: The invention relates to a catheter system comprising a totally implantable reservoir for a treating agent, and at least one catheter connected thereto. The reservoir is designed to have a variable volume so that it can be positioned in the tissue by a small cannula needle when its volume is small and can be brought to the required internal volume in situ.

  • Syringe for Doppler sonographically aided penetration
    Patent number: 5080103
    Abstract: In a syringe for ultrasonically aided penetration of arterial or venous vessels the transmitter and the receiver are arranged in the piston. This simplifies manipulation and, particularly if a physiological saline solution is simultaneously injected to directly couple the ultrasound to the soft parts surrounding the vessel, enables vessels even in anatomically difficult positions to be localized simply and without the danger of complications.
