  • Publication number: 20240188989
    Abstract: A delivery sheath comprises inter-connected fingers extending around a cylindrical inner lumen and forming one or more gaps. The inter-connected fingers may be configured to assume a default form in which the inner lumen has a first width, bend in response to an implant passing through the inner lumen to cause at least a portion of the inner lumen to increase beyond the first width, and/or elastically return to the default form following removal of the implant from the inner lumen.

  • Publication number: 20210277488
    Abstract: A detection panel for the universal detection of SARS-like coronaviruses and SARS-CoV-2 viruses and a method for using the detection panel are provided. The detection panel may be known as a Center for Discovery and Innovation (“CDI”) detection panel (CDI Enhanced COVID-19 Test) and may also include an additional primer/probe set in the detection panel to detect the human RNase P gene (RP) in control samples and clinical specimens. The detection panel is designed for both universal detection of SARS-like coronaviruses using an E gene (envelope) detection assay, and specific detection of the SARS-CoV-2, using an N2 (nucleocapsid) detection assay.

  • Patent number: 10975623
    Abstract: A constant velocity joint for downhole power transmission has a first insert mounted in a radially extending drive shaft arm. The first insert engages a second insert mounted along a slot formed in a tubular housing disposed to receive the arm. The material for the two inserts may be different, having different galling properties. An insert may be shaped to have at least a flat surface, a cylindrical surface intersecting the flat surface, and a conical surface intersecting the cylindrical surface. The inserts may extend beyond the cavities in which they are mounted. Opposing cavity walls adjacent the cavity opening may be angled away from one another to permit the insert to flex under a load. The back wall of a cavity and back surface of an insert may be arcuate to permit rotational movement of the insert under a load.

  • Patent number: 10939793
    Abstract: The handheld cleaning apparatus provides a handheld cleaning apparatus comprising a removable handle, abrasive particles, angled edges, open channels, and a flexible yet durable surface for scouring. The invention creates an abrasive, or “sanding,” cleaning apparatus that is better suited for cleaning dirty surfaces than a traditional cleaning sponge. The handheld cleaning apparatus retains the abrasive outer shell of a sanding sponge but is much more flexible and water permeable than current sanding sponges. To this end, the handheld cleaning apparatus comprises open channels, or “blow holes,” that promote water flow through the sponge and give the sponge flexibility. The size and the number of the channels vary by the material or density of the sponge. The handheld cleaning apparatus, additionally, contains a handle that is removably attached, which enables the consumer the ability to connect one or more cleaning apparatuses together to form the desired shape and form of the cleaning apparatus.

  • Patent number: 10934577
    Abstract: Nucleic acid amplification assays for mutations to two short sections of the fungal gene FKS1. Mutations in these target sequences have been shown to correlate with resistance to echinocandin-class drugs. Assays may include detection by sequencing or by labeled hybridization probes. Also, primers, probes and reagent kits for performing such assays.

  • Patent number: 10690179
    Abstract: An assembly for use in a wellbore can include a drill string having an outer housing and a thrust bearing sleeve positioned within the outer housing of the drill string. The assembly can also include a stationary thrust bearing positioned within the thrust bearing sleeve and coaxially around a mandrel extending through a longitudinal length of the thrust bearing sleeve. The assembly can further include an interlocking component including a first end coupled to the stationary thrust bearing and a second end positioned in a recessed portion of a housing of the drill string for preventing the stationary thrust bearing from rotating about a central axis of the mandrel, and for allowing the stationary thrust bearing to rotate about one or more axes perpendicular to the central axis. The assembly can include a flexible member for opposing a rotational force applied to the stationary thrust bearing by another thrust bearing.
