Patent number: 10893926Abstract: Apparatus for permanent placement across an ostium of a left atrial appendage in a patient, which includes a filtering membrane configured to extend across the ostium of the left atrial appendage. The filtering membrane has a permeable structure which allows blood to flow through but substantially inhibits thrombus from passing therethrough. The apparatus also includes a support structure attached to the filtering membrane which retains the filtering membrane in position across the ostium of the left atrial appendage by permanently engaging a portion of the interior wall of the left atrial appendage. The support structure may be radially expandable from a first configuration to a second configuration which engages the ostium or the interior wall of the left atrial appendage. The filtering membrane may define an opening therethrough that is configured to expand from a first size which inhibits the passage of thrombus therethrough to a second size which allows an interventional device, e.g.Type: GrantFiled: September 4, 2015Date of Patent: January 19, 2021Assignee: Atritech, Inc.Inventors: Robert A.

Publication number: 20200201948Abstract: A system for automating design of a support frame for artificial rockwork structures. The system includes a processor and memory storing a three dimensional (3D) mesh for an exterior surface of a rockwork structure. The system includes an offset module that is code/instructions or software executed by the processor to process the 3D mesh and generate an offset mesh defining a 3D topology of the exterior surface at an offset distance from the 3D mesh. The system also includes a chip-defining module including software executed by the processor to divide the offset mesh into a plurality of subsections. The system further includes a rebar line-defining module with software executed by the processor to generate an assembly of rebar pieces for each of the subsections that defines for each of the rebar pieces a length, a location within the subsection, and a set of spaced apart bends.Type: ApplicationFiled: December 20, 2018Publication date: June 25, 2020Inventors: ANDREW STEVEN MARSHALL, DANIEL ROBERT RICHARDSON, KATRINA ANNE WILDER, DOUGLAS CHARLES SCHARFENBERG, SHAWN MICHAEL HOLMES, HEPZIBAH CHANDRANAND, MIKE S.

Publication number: 20180064103Abstract: Many pesticide, insecticide or fertilizer-type formulations prove beneficial when applied to a seed prior to planting. However, when mixing multiple formulations simultaneously in a custom blend, problems arise regarding the viscosity and stability of the blend that result in inadequate handling, coverage and stability. Further, dusting off of certain pesticides must be minimized. The present invention comprises the addition of specific surfactants to the custom blend formulation to manage viscosity, thus improving pumpability, seed coverage, and stability of custom blends while reducing seed dust off.Type: ApplicationFiled: July 21, 2016Publication date: March 8, 2018Inventors: John M.
