  • Patent number: 11433216
    Abstract: Methods for making medical devices and portions of medical devices (e.g., intravascular catheters, catheter shafts, and tubular guiding members) are provided. Example methods may include providing a first ribbon comprising one or more thermoplastic materials and a piece of shrink tubing defining a shrink tube lumen and forming a first assembly by positioning the first ribbon inside the shrink tube lumen and urging the first ribbon to assume a tubular shape in which the first ribbon defines a ribbon lumen. A second assembly may be formed by loading an inner tubular member over a mandrel and forming or placing a support structure over an outer surface of the inner tubular member. A third assembly may be formed by inserting the second assembly into the ribbon lumen defined by the first ribbon of the first assembly. The third assembly may be heated to a process temperature.

  • Publication number: 20220143360
    Abstract: Catheters incorporating a thin film polymeric layer or layers. The thin film may have a wall thickness of about 0.00025? +/? less than 0.0001? to about 0.0015? +/?0.0002?, for example. The thin film may be formed by extruding a sheet and cutting the sheet into elongate ribbons, each having two opposing long edges. The ribbon may be rolled or wrapped to define a tubular shape with a gap between the long edges. Heat and pressure may be applied to close the gap, abut the edges and form a longitudinal joint. The joint may extend along a portion of the length of the tubular shaft or most of the length of the tubular shaft. The tubular-shaped thin film layer may have a uniform wall thickness around the circumference, and the uniform wall thickness may extend across the joint.

  • Publication number: 20210128156
    Abstract: A plurality of structures that resiliently attract one another are provided for implanting in a patient around a body tissue structure of the patient. For example, the body tissue structure may be the esophagus, and the plurality of structures may be implanted in an annulus around the outside of the esophagus, the annulus being substantially coaxial with the esophagus. The attraction may be between annularly adjacent ones of the structures in the annulus, and it may be provided, for example, by magnets or springs. The array of structures is preferably self-limiting with respect to the smallest area that it can encompass, and this smallest area is preferably large enough to prevent the apparatus from applying excessive pressure to tissue passing through that area.
