  • Publication number: 20220177824
    Abstract: Material processing apparatus, systems, methods, and products are described. An example of a material processing apparatus includes a holding member, a base, a tensioning member, an actuator, and a first inner member. The holding member defines a holding member passageway. The base is attached to the holding member. The tensioning member is partially disposed within the holding member passageway. The tensioning member defines a tensioning member passageway. The tensioning member is moveable relative to the holding member between a first position and a second position. The actuator is attached to the tensioning member and is moveable in a first direction and a second direction. Movement of the actuator results in movement of the tensioning member between its first position and second position. The first inner member is adapted to be disposed within the tensioning member passageway.

  • Patent number: 11317892
    Abstract: Disclosed are embodiments of devices and methods for imaging the inside of a body part, such as a blood vessel. In particular embodiments, a catheter has a chamber within which is a transducer. A wire guide channel extends throughout the length of the catheter. The transducer is rotatable about the wire guide channel and the transducer is driven by a cable or other device that is connected to a motor which is located outside the catheter. In one form, a torque cable connects the transducer to the motor. In other embodiments, a pusher piece having a plurality of lumens is positioned in the catheter. Each of the lumens is sized to receive a cable, wire, and/or flushing fluid. The lumens maintain the orientation and separation of the cables, wires, and/or to flushing fluid.

  • Publication number: 20220010251
    Abstract: Differential pressure material processing systems, apparatus, methods, and products are described. An example embodiment of a differential pressure material processing system includes a tank, a holding member, and a sheet of tissue disposed within the holding member. The holding member defines a first holding member chamber and a second holding member chamber. The first holding member chamber has a first pressure when a fluid is disposed within the first holding member chamber. The second holding member chamber has a second pressure when a fluid is disposed within the second holding member chamber. The second pressure is different than the first pressure.

    Abstract: Storage devices, loading devices, delivery systems, kits, and associated methods for implantable medical devices are described. An example embodiment of a storage device includes a storage member, a first cap, and a second cap. The storage member has a first end, a second end, and a main body that defines a first opening, a second opening, a passageway, a separating wall, and a plurality of holes. The passageway has a first portion and a second portion. The first portion extends from the first end of the storage member to the separating wall and the second portion extends from the second end of the storage member to the separating wall. Each hole of the plurality of holes extends through the separating wall and provides access between the first portion and the second portion. Each of the first and second caps is releasably attached to the storage member.

  • Patent number: 11071521
    Abstract: There are disclosed embodiments of devices and methods for imaging the inside of a body part, particularly a blood vessel. In particular embodiments, a catheter has a tip chamber, within which is an ultrasound transducer mounted on a pivot mechanism, a motor for turning the transducer, and an implement for pivoting the transducer. Examples of such an implement are a linear motor, a shaft or filament, and the pivot mechanism may be biased to return to a base position when the implement is not pivoting the transducer. In other embodiments, a mirror reflecting ultrasound signals from the transducer may be rotated and/or pivoted, using similar mechanisms.

  • Patent number: 10653391
    Abstract: Among other things, there is disclosed structure and methods for registering images obtained through internal (e.g. intravascular) ultrasound devices. Embodiments of a device with a rotating ultrasound beam is provided, with a wall of the device being anisotropic in ultrasound passage. As examples, a cable opaque to ultrasound is attached along the wall of the device, so that the ultrasound beam at the location of the cable is blocked, reflected or scattered. As another example, a thin film of metallic material is placed on or in the wall to allow a portion of the beam to be blocked or attenuated. The imaging system recognizes the changes to the signals made by the anisotropic wall, and registers successive images according to those changes.

  • Patent number: 10328290
    Abstract: Systems and methods for treating a blood clot positioned within a blood vessel are disclosed. In one embodiment, a balloon member is positioned on a distal end region of a catheter and an ultrasound emitting element is positioned within the balloon member and arranged for actively emitting ultrasound. In some exemplary embodiments, the disclosure provides a multi-wall balloon member and a multi-lumen catheter with at least one and/or all cavities of the balloon member arranged for heat transfer with the ultrasound emitting element. The disclosure also provides catheter arrangements with an ultrasound emitting element arranged to heat tissue adjacent to the balloon member. Additionally, in some embodiments, at least one and/or all walls of the balloon member have apertures arranged to release a therapeutic agent such as a thrombolytic drug.
