  • Rapidly exchangeable coronary catheter
    Patent number: 6129708
    Abstract: A rapidly exchangeable catheter for use in the coronary arteries includes an elongate relatively stiff proximal segment that defines an inflation lumen, an intermediate, shorter segment formed from a more flexible plastic material and having two lumens, and a third, single lumen distal segment. A balloon or other instrumentality adapted to operate in a coronary artery is mounted to the distal region of the catheter. The intermediate and distal segments include a guidewire lumen by which the catheter may be advanced along a guidewire. The proximal segment may include an inflation lumen when the operating instrumentality at the distal end of the catheter is a balloon.
    Type: Grant

  • Vented spike connection component
    Patent number: 5041105
    Abstract: A connection component suitable for use with an enteral fluid delivery set is arranged in the form of a replacement for the cap of a pre-filled, foil sealed fluid container. The connection component includes a fluid outlet passage which is arranged in the form of a projecting spike which penetrates and opens the foil seal as the connection component is attached to the pre-filled container.
