  • Publication number: 20200215234
    Abstract: The present invention relates to a drug-eluting medical device, in particular a balloon for angioplasty catheters with drug elution to prevent the restenosis of the vessel subjected to angioplasty. More particularly, the present invention relates to a catheter balloon completely or partially coated with paclitaxel in hydrated crystalline form or in hydrated solvated crystalline form, having an immediate release and bioavailability of a therapeutically effective amount of paclitaxel at the site of intervention. The balloon can be made of a polyether-polyamide block copolymer, or a polyester amide, or polyamide-12.

  • Patent number: 10532189
    Abstract: The invention relates to a drug-coated balloon catheter which has a catheter balloon mounted on its distal end and an expansion protection surrounding the same. The invention is characterized in that the catheter balloon is protected from premature expansion even under strong mechanical stress and in that the catheter balloon folds back more easily after dilation.

  • Publication number: 20190373899
    Abstract: A conveyor baking oven for continuous baking operation has at least two conveyor baking spaces. A plurality of oven modules of the baking oven have baking spaces, which combine to form the conveyor baking spaces between a respective initial oven module arranged in a leading manner when seen in the bakery product conveying direction, and a respective final oven module, which is the last in row when seen in the bakery product conveying direction. The oven modules have a multi-level arrangement such as to define the at least two conveyor baking spaces. A bakery product conveyor device is used to continuously convey bakery products through the conveyor baking spaces. A thermal oil heating device having at least one thermal oil heat exchanger is used to heat the conveyor baking spaces by radiant heat. The resulting conveyor baking oven is operable efficiently and adaptable to various throughput requirements.

  • Publication number: 20190376751
    Abstract: A pipe heat exchanger for a baking oven has a plurality of heat exchanger pipe sections configured to guide a heat carrier fluid, the heat exchanger pipe sections being arranged adjacent to each other in an arrangement plane. A distance between adjacent pipe sections is smaller than a pipe diameter and greater than 1% of the pipe diameter. The result is a pipe heat exchanger, which allows a baking space to be heated efficiently and variably.

  • Publication number: 20190373900
    Abstract: An endless conveyor belt for a conveyor baking oven has a conveyor run with a plurality of belt links configured in one piece, the belt links extending transversely to a conveying direction and being mounted between lateral guides. Seen in projection in a plane perpendicular to a conveying plane, each of the belt links has gas passage openings. These gas passage openings have a total opening surface area, which amounts to at least 30% of a total surface area of the projection of the belt link. The result is an endless conveyor belt, which allows a baking space of a conveyor baking oven equipped with an endless conveyor belt of this type to be heated more efficiently and flexibly.
