  • Publication number: 20220333705
    Abstract: A safety valve is configured for use at temperatures at or above 760° C. (1400° F.). The safety valve includes a closure assembly that can create a self-energizing, metal-to-metal seal. In one implementation, this closure assembly includes a disc with an arcuate finger that circumscribes an axis of fluid flow through a seat. The arcuate finger may extend inwardly toward this axis and downwardly toward the seat. This geometry permits the finger to flex in response to pressure of fluid that impinges on the downstream side of the disc, such flexure causing a first sealing surface on the disc to more forcefully contact a second sealing surface on a seat.

  • Publication number: 20220304813
    Abstract: Systems are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. The systems include a drill guide adapted to create a pilot SI joint opening in the dysfunctional SI joint through an incision comprising a length no greater than 3.0 cm; portions of the pilot SI joint opening being disposed in the sacrum and ilium bone structures. The drill guide includes a tri-mode fixation system adapted to position and stabilize the drill guide during creation of the pilot SI joint opening in the dysfunctional SI joint and delivery of the SI joint prosthesis therein. The systems also include a SI joint prosthesis configured to be inserted into the pilot SI joint opening of the dysfunctional SI joint, and a prosthesis deployment assembly configured to engage the SI joint prosthesis and advance the SI joint prosthesis into the dysfunctional SI joint.

  • Publication number: 20220273448
    Abstract: Methods are described for conducting minimally invasive medical interventions utilizing instruments and assemblies thereof to stabilize and/or fixate a dysfunctional sacroiliac (SI) joint. In one embodiment, a drill assembly is advanced from a posterior approach into the SI joint to create a pilot SI joint opening; portions of which being disposed in the sacrum and ilium bone structures. After the pilot SI joint opening is created, a SI joint prosthesis is inserted into the pilot SI joint opening, wherein the SI joint prosthesis is positioned in the dysfunctional SI joint at a distance of at least 3.0 mm away from the SI joint dorsal recess.

  • Publication number: 20220268795
    Abstract: A calibration device is disclosed. The device comprises an array of teaching pendants. The device comprises a translation actuator configured to translate the array of teaching pendants to a set of x and y positions, wherein the x and y positions are measured in a plane substantially parallel to a floor of an instrument deck. The device comprises a plurality of height actuators configured to move each of the teaching pendants in a direction substantially perpendicular to the plane. One or more of the teaching pendants contact one or more teaching objects of an array of teaching objects above the instrument deck as a result of a position of the array of teaching pendants.

  • Publication number: 20220205170
    Abstract: A coated barrier fabric for use in a reusable medical product (e.g., surgical gown, surgical drape, etc.) is provided and has two woven or knitted plies. Each of the two plies are coated on one side with a non-fluorine containing polymer and retain similar comfort and feel of uncoated woven or knitted fabrics. The coated sides of the plies face each other (i.e., inwardly) in the interior of the barrier fabric. Because of the orientation of the plies, the coated sides of the plies can come into direct contact with and move freely against each other within the interior of the barrier fabric. The coating on each of the plies is protected from exterior and environmental factors, including repeated institutional laundering/autoclave cycles, that could abrade and degrade the coating. Thus, the useful life of the reusable medical product including the barrier fabric is extended.

  • Patent number: 11166500
    Abstract: A personal protective equipment (PPE) rear opening isolation gown is provided that can be used by workers in the healthcare industry. The isolation gown is reusable and can provide for ease of doffing, such as in a pull forward manner that is consistent with how current users of disposable isolation gowns are accustomed to removing such gowns, without substantial risk of damaging (e.g., tearing) the gown and without substantial risk of the transfer of potentially harmful microorganisms, body fluids, and/or particulate material, to the neck or hair on the head or neck of a wearer. The reusable, rear opening isolation gown is provided with an easy release fastener(s) that provides a safe and secure hold when fastened but permits the gown to be removed easily, quickly, and more safely than other reusable options.
