  • Patent number: 11779449
    Abstract: A filter having a first set of members and a second set of members defining a trap sized to fit into a blood vessel. Each of the first and second members are configured to resiliently extend from the trap. At least one of the first set of members includes a first surface for engaging the vessel wall such that the at least one of the first set of members resists downstream movement within the vessel. At least one of the second set of members includes a second surface for engaging the vessel wall such that the at least one second member resists upstream movement within the vessel.
    Type: Grant

  • Patent number: 11766345
    Abstract: A balloon for medical treatments such as percutaneous transluminal coronary angioplasty (PTCA), delivery of a vascular stents or stent grafts, employs reinforcement materials that are patterned so as to promote consistent folding of the balloon. Also disclosed are methods and apparatus for biocidal treatment using a balloon, including balloons with fiber fabric reinforcements.

  • Patent number: 11702776
    Abstract: A medical balloon with a variable diameter that is reinforced with continuous fibers woven to form a fabric with a varying number of layers and fiber densities. Portions of the balloon having a relatively smaller diameter are reinforced with a fabric having a reduced fiber density and an increased number of layers to facilitate the placement of the layers. The fabric also includes a braiding pattern that facilitates the transition from a single layer fabric to a multiple layer fabric. Also described is a manufacturing method for the braiding and layering.
