  • Patent number: 10765539
    Abstract: A stent graft device that includes a frame, a cover material covering the frame, and an anchoring member having an adjustable geometry is provided. The anchoring member may be incorporated as part of the frame or coupled thereto. The anchoring member may be formed of a material having a tensile strength such that it can be bent, straightened, or otherwise changed in shape. Tissue growth over and/or around the anchoring member anchors the stent graft device within a lumen. During removal of the stent graft device, the geometry of the anchoring member changes to allow the anchoring member to be removed from the tissue growth along a removal path with minimal trauma. The design and/or shape of the anchoring member is not particularly limited so long as the anchoring member has an adjustable geometry that permits tissue overgrowth and subsequent removal from the tissue overgrowth with minimal trauma.

  • Patent number: 10695084
    Abstract: A thrombus treatment device includes a support wire, a body frame portion that is disposed about an axis defined by the support wire, one or more tethers that each have a first end and a second end. Each of the one or more tethers is attached at its first end to the body frame portion, and at its second end to a collar that couples the second end of each of the multiple tethers to the support wire. When the collar is advanced to a position substantially within a region interior of the body frame portion, a rotational actuation of the support wire causes a swiveling motion of the one or more tethers. The swiveling motion of the tethers operates to macerate a thrombus.

  • Patent number: 10676344
    Abstract: An environmental-barrier layer can protect a die or an array of die. A substrate that includes various functional components can be coupled to a porous environmental-barrier layer to form an array of die prior to dividing the array into individual die. The porous environmental-barrier layer can be a layer that includes polymer or fluoropolymer. The porous environmental-barrier layer can also be a filter layer for allowing certain waves to pass through and blocking particles and other debris. The porous environmental-barrier layer can protect each die in the array and the functional components from damage by protecting the die and the functional components from mechanical, electrical, or environmental damage (e.g., contamination by fluid or dust) without impeding a function of the functional components.
