Publication number: 20240173154Abstract: A stent incorporating flexible, preferably polymeric, connecting elements into the stent wherein these elements connect adjacent, spaced-apart stent elements. Preferably the spaced-apart adjacent stent elements are the result of forming the stent from a helically wound serpentine wire having space provided between adjacent windings. Other stent forms such as multiple, individual spaced-apart ring-shaped or interconnected stent elements may also be used. The connecting elements are typically web-shaped and result from creating slits or apertures in a covering of graft material applied to the stent and then, for example, applying heat to cause the slits or apertures to enlarge. The remaining graft material forms the interconnecting webs between the adjacent stent elements.Type: ApplicationFiled: December 5, 2023Publication date: May 30, 2024Inventors: Dustin C. Burkart, Edward H. Cully, Jeffrey B. Duncan, Cody L. Hartman, James D. Silverman

Publication number: 20240123205Abstract: Described herein are encapsulation devices that include an inner layer, an outer layer, a cell containment layer positioned between the inner and outer layer, and structural elements disposed within the cell containment layer to separate the inner and outer layers by a separation distance. The structural elements define reservoir spaces for the retention of a biological moiety (such as cells) therein. The structural elements maintain a separation distance both under external compressive forces and under internal expansive forces, such as undergoing a geometric change in the encapsulation device or during crushing and subsequent expansion of the cell encapsulation device. In some embodiments, a reinforcing layer is positioned between the inner layer and the cell containment layer. In addition, the encapsulation device may include at least one configuration element. Methods of placing encapsulation devices in a body conduit intra-luminally, extra-luminally, and via an open surgical procedure are also disclosed.Type: ApplicationFiled: February 25, 2021Publication date: April 18, 2024Applicant: W. L. Gore & Associates, Inc.Inventors: Edward H. Cully, Jeffrey B. Duncan, Erin Hutchinson, Paul D Drumheller, Justin Tettenborn, Regina M Dell

Patent number: 11072497Abstract: An automatic belt biasing device is provided for biasing a drive belt into frictional contact with rollers of a conveyor. The belt biasing device maintains a drive belt in contact with rollers of a live roller conveyor to provide drive for the rollers to propel items or packages along the conveyor. A spring attached to a pivot arm or pair of scissoring pivot arms adjusts a biasing force applied by guide wheels of the belt biasing device to the drive belt due to changes in drive belt tension. The belt biasing device may be selectively adjustable based on required roller pitch distances. The belt biasing device is pivotably coupled to the roller conveyor allowing the guide wheels to apply equal pressure to the drive belt while allowing the pivot arms to actuate and increase or decrease the biasing force provided by the belt biasing device.Type: GrantFiled: May 8, 2020Date of Patent: July 27, 2021Assignee: Dematic Corp.Inventors: Jeffery D. Duncan, Nicholas M. Thomas, Nolan R. Pilarz, Thomas H. Triesenberg, Shreedhar M. Hebbur

Patent number: 11066242Abstract: A positive displacement sorter and method of diverting articles includes a conveying surface configured to convey articles in a longitudinal direction and at least one diagonal take-away lane, extending diagonally from the conveying surface to receive articles being diverted from said conveying surface. A plurality of pushers are configured to move together in a lateral direction in order to displace an item on the conveying surface to the diagonal take-away lane. A rotational system is configured to rotate a leading portion of a diverted article in the direction of the take-away lane. A belt drive system is provided for driving live roller conveyors about a curved section of a roller conveyor of the sorter. The drive belt is guided along a single conical drive plane that maintains the orientation of the drive belt relative to the single conical drive plane and limits twisting and stress in the drive belt.Type: GrantFiled: October 24, 2019Date of Patent: July 20, 2021Assignee: Dematic Corp.Inventors: Nolan R.

Patent number: 10967989Abstract: A tail-cone reinforcement angle of a Cessna 180-185 series aircraft is repaired by the removal of an aft most section of that tail-cone reinforcement angle and its replacement with an elongated splice body. The elongated splice body is attached to the remainder of the tail-cone reinforcement angle and to the tail-cone portion of the fuselage of the aircraft. The aft section of the original tail-cone reinforcement angle is subject to the development and propagation of cracks in the area of the rear pivot shaft receiving bore, which cracks render the aircraft unfit for use. The invention includes the provision of a suitable elongated splice body, a method for its installation, and a tool kit which is usable in accomplishing the removal and replacement of the aft section of the tail-cone reinforcement angle.Type: GrantFiled: November 12, 2020Date of Patent: April 6, 2021Assignee: QMI, INC.Inventor: William D.
