  • Patent number: 11376110
    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.

  • 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.

  • Publication number: 20220054806
    Abstract: Systems, devices and methods for treating lymphatic congestion are disclosed. In one method, a balloon is placed at or near the veno-lymph junction. The balloon is inflated and deflation through cycles of slow inflation and rapid deflation. In another embodiment, an arteriovenous fistula is created near the veno-lymph junction. Alternate embodiments may also include axial pumps, stents, or balloons in combination with the fistula. These devices and methods create an acceleration of the blood flow past the lymphatic duct which reduces local pressure via the Venturi effect and according to the Bernoulli principle which facilitates lymph entering into the bloodstream.

  • 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.

  • Publication number: 20200289300
    Abstract: An asymmetrical stent includes a tubular shaped framework with a first region that is exclusive of a second region, both of which extend less than completely around a longitudinal axis. The first region and the second region expand responsive to inflation of a balloon positioned with the tubular shaped framework. The first region is more resistant to expansion than the second region. The tubular shaped framework includes a first plurality of barbs and a second plurality of barbs that all point away from the longitudinal axis. The first and second plurality of barbs being on respective sides of a plane that includes the longitudinal axis and bisects the first region.

  • Publication number: 20200060525
    Abstract: Methods of treating diverticulosis and medical devices suitable for use in such methods are described herein. In an embodiment, a method of treating diverticulosis in an animal comprises clearing the lumen of the colon of the animal of solid matter, isolating a treatment portion of the colon, applying suction at a point within the lumen of the colon to depressurize the treatment portion, applying a material to the external surface across at least one diverticulum of the diverticula on the colon, and removing the suction. In some embodiments, the material comprises an adhesive. A step of applying a second material across at least one diverticulum of the diverticula on the colon can also be included.

  • Patent number: 10022218
    Abstract: Animal models useful in the evaluation of medical devices, such as intraluminal medical devices, including intraluminal valve prostheses, are described. An example animal model comprises an animal in which a chordae tendineae attached to at least one of the leaflets of the tricuspid valve has been cut during an interventional procedure. Methods of evaluating intraluminal medical devices are also described. An example methods comprises cutting chordae tendineae attached to a leaflet of a tricuspid valve of an animal; allowing the animal to recover from the step of cutting the chordae tendineae; implanting an intraluminal medical device at a target site within a body vessel of the animal; allowing the animal to recover from the step of implanting an intraluminal medical device; and monitoring in vivo performance of the intraluminal medical device.
