  • Patent number: 11986882
    Abstract: An apparatus and method for fabricating a three-dimensional object from a representation of the object stored in memory. The apparatus includes a build platform having a build gap defined therein. A base plate is initially supported along a lower surface of the build platform such that an edge of the base plate extends along and closes off the build gap. A powder delivery assembly is configured to supply powder to the build gap. At least one directed energy source is configured to apply directed energy to at least a portion of the build gap to form a layer of the three-dimensional structure. An advancement assembly configured to selectively engage with the base plate and/or the three-dimensional structure to hold the base plate and the three-dimensional structure in a fixed position during forming of a layer and to advance the base plate and the three-dimensional structure once the layer is formed.

  • Patent number: 11986612
    Abstract: Flexible high-pressure angioplasty balloons are disclosed herein which utilize an inflatable balloon positioned upon the catheter and a supporting structure secured over or along the catheter at a first location proximal to the balloon and at a second location distal to the balloon. Inflation of the balloon reconfigures the supporting structure to urge the first location and the second location towards one another thereby inhibiting longitudinal elongation of the balloon relative to the catheter. The supporting structure may surround, support, or otherwise extend over the entire length of the balloon and allows for the balloon to retain increased flexibility which enables the balloon to bend or curve even at relatively high inflation pressures.

  • Patent number: 11958244
    Abstract: A manufacturing system includes a plurality of rails, a plurality of head manipulating mechanisms respectively coupled to the rails, and a plurality of automated fiber placement (AFP) heads respectively coupled to the head manipulating mechanisms. The rails are arranged around a barrel-shaped layup tool, and each rail is parallel to a tool axis. Each head manipulating mechanism moves along a rail. The head manipulating mechanisms position the AFP heads in circumferential relation to each other about a tool surface of the layup tool. A total quantity of AFP heads comprises the maximum number of AFP heads that can be circumferentially arranged in longitudinal alignment with each other on the layup tool without interfering with each other while applying layup material over the tool when the layup tool is stationary and during rotation about the tool axis, to thereby fabricate a green state layup having a barrel shape.
