  • Patent number: 11957857
    Abstract: A process for arranging a protective sheath on a drug-coated balloon catheter in a machine. The protective sheath is transported via a transport system into a holding device. A drug coated area of the balloon catheter from contact with the machine. The protective sheath is arranged on a drug-coated area of the balloon catheter by machine relative motion between the balloon catheter and the protective sheath. The protecting can be placing at least one first and one second flexible film between the balloon catheter and a guide of the machine during the relative motion or can be holding the balloon catheter at a position on the catheter away from the drug-coated area during the relative motion.

  • Patent number: 11890214
    Abstract: A process for repositioning a drug-coated stent that is pre-crimped on a balloon of a balloon catheter extending in an axial direction so that an inner surface of the stent lies against an outer surface of the balloon. The stent is gripped with at least one contact element and a protection device between the stent and the at least one contact element to prevent contact between the stent and the at least one contact element.

  • Patent number: 11707372
    Abstract: A process for arranging a stent, especially a drug-coated stent, on a balloon of a balloon catheter. At a stent implantation site (e.g., during an angioplasty procedure), the balloon of the balloon catheter serves to expand the stent radially, so that the stent, e.g., opens a vascular stenosis and is securely fixed to the vessel wall. Pressure plates are arranged and operate to maintain a protection device that avoids contamination of the stent.

  • Patent number: 11382780
    Abstract: A system and method for loading a self-expandable prosthetic device into a delivery device. The system includes a compression member that has a chamber with a tapered inner surface, a support member, a splay member and a constriction member. The compression member and the constriction member can be releasably attached to each other directly or via a spacer element, in two different positions relative to each other. The first position offers an optimal configuration for releasable attachment of the prosthetic device to the delivery device and the second position offers an optimal configuration for reducing the diameter of the delivery device. The risk of damaging the delivery device and to the prosthetic device during the loading procedure is thereby reduced.
