  • Patent number: 11337684
    Abstract: An occluder has a first disk-shaped structure with a grid, wherein the first disk-shaped structure is woven from at least two groups of braided wires, and the two groups of braided wires are crossed to form multiple rings of crossing points. A blocking membrane is also arranged in the disk-shaped structure, with an edge of the blocking membrane connected to the outermost ring of crossing points of the multiple rings of crossing points through a sewing wire, and the number of crossing points in the outermost ring of crossing points sewn with the blocking membrane is smaller than the number of all the crossing points in the outermost ring of the crossing points. The occluder can reduce the possibility of the phenomenon where the edge of the blocking membrane cannot abut against a disk face edge of the occluder, thereby improving the occlusion effect of the occluder.

  • Patent number: 11051877
    Abstract: Medical devices for diagnosis or treatment of tissue in a body. Representative devices include an elongate shaft having a proximal portion and a distal portion configured for movement relative to the proximal portion. A flexible member having a predetermined stiffness is disposed between the proximal and distal portions. One or more coils and an electrically passive element are disposed within the shaft with either the coils or element configured for movement with the distal portion. The element comprises a material effecting an electrical characteristic of the coils. Movement of the distal portion in response to its contact with the tissue and relative movement of the coils and element causes a change in the electrical characteristic in at least one of the coils indicative of at least a contact force magnitude between the distal portion and the tissue. Several embodiments allow determination of both force magnitude and force vector direction.

  • Patent number: 11039898
    Abstract: Improvements for use with tissue expanders are provided. A tissue expander includes: a selectively inflatable and deflatable shell that is configured to be implanted; and an access port for selectively inflating and deflating the shell, the access port comprising a sidewall, a base at a first end, and a membrane at a second end opposite the first end, wherein the sidewall and the base of the access port are constructed of a material that is non-reactive with a magnetic resonance imaging (MRI) machine. In embodiments, the tissue expander includes a magnet at the access port. In embodiments, the magnet is configured with a physical size and magnetic force such that, when the tissue expander is implanted, the magnet is detectable by an external magnetometer sensor but is not detectable by an external dangle-magnet.

  • Patent number: 11020210
    Abstract: There is provided a method for controlling a flow of intestinal contents in the intestinal passageway of a patient's intestines. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the intestinal tissue wall) at least one portion of the intestinal tissue wall to influence the flow in the intestinal passageway, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the intestinal passageway. The method can be used for restricting or stopping the flow in the intestinal passageway, or for actively moving the fluid in the intestinal passageway, with a low risk of injuring the intestines.
