Abstract: A prosthetic device includes a main body, a first anchor, and a second anchor. The main body has an atrial end and a ventricular end. The main body tapers from the atrial end to the ventricular end. The first and second anchors are coupled to the main body and are movable toward and away from the main body.

Abstract: A machine accesses a first image captured prior to initiation of a procedure, where the first image depicts a set of instruments, as well as a second image captured after initiation of the procedure, where the second image depicts a proper subset of the set of instruments depicted in the first image. From the first and second images, the machine may determine that an instrument among the set of instruments depicted in the first image is not depicted among the proper subset of the set of instruments in the second image, and then cause presentation of a notification that indicates the instrument not depicted in the second image is missing. Alternatively, or additionally, the machine may determine whether an instrument among the set of instruments was used in the procedure, and then cause presentation of a notification that indicates whether the instrument was used in the procedure.

Abstract: Bone anchor assemblies and related methods are disclosed herein that can provide for improved fixation of a primary bone anchor. A bone anchor assembly can include a base rotatably received within a rod-receiving member. The base can have a toroid body with a radially-extending portion including at least one auxiliary bone anchor opening that can receive an auxiliary bone anchor to augment fixation of a primary bone anchor of the bone anchor assembly. The base can be rotated relative to the rod-receiving member and the primary bone anchor such that the at least one auxiliary bone anchor opening can be placed in a desired position for supplemental fixation.

Abstract: A method for tracking surgical items with a system including an imaging system, a display, and one or more processors is provided. The method includes capturing a video that depicts a user handling the surgical items, and performing computational analysis of the video to detect a characteristic arm motion of the user which is indicative of the user moving the surgical item to be counted in to a surgical procedure. The method further includes, in response to each instance of the characteristic arm motion being detected, updating a count of surgical items and displaying the updated count on the display.

Abstract: Bone anchor assemblies are disclosed herein that can provide for improved fixation as compared with traditional bone anchor assemblies. An exemplary assembly can include a bracket or wing that extends down from the receiver member. The distal portion of the wing can define a bone anchor opening through which one or more auxiliary bone anchors can be disposed to augment the fixation of the assembly's primary bone anchor. A distal surface of the distal portion of the wing can be obliquely angled relative to a proximal-distal axis of the spanning portion to face one of a caudal direction or a cephalad direction. A distal surface of the distal portion of the wing can be obliquely angled relative to the proximal-distal axis of the spanning portion to face one of a medial direction or a lateral direction. Surgical methods using the bone anchor assemblies described herein are also disclosed.

Abstract: A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing to assess intra-arterial fluid volume is described. The system uses averaging of similar pulses based on prior (n?1; n minus 1) R-to-R pulse wave duration, and prior-prior (n?2; n minus 2) R-to-R pulse wave duration, to determine a patient's fluid status and whether it is below or above optimal intravascular hydration.

Abstract: Cold brewing systems for beverages such as coffee, espresso, tea, or infused water and methods of using the systems. The systems use two or more electrodes to create a Pulse Electrical Field (PEF) used to solubilize and extract numerous organic compounds from coffee grounds, tea, or other flavored substances. The PEF brewing system may be a flow-through, a drip, or a pot brew system.

Abstract: Methods and systems for making three-dimensional printed articles. In one example, a method of making a three-dimensional article can include printing a conductive element including a composite of a conductive material and a polymeric build material; printing an adjacent portion in contact with the conductive element, where the adjacent portion includes a nonconductive polymeric build material; and heating the conductive element by running an electric current through the conductive element, and thereby heating the adjacent portion to a temperature sufficient to change a physical property of the nonconductive polymeric build material of the adjacent portion.

Abstract: The invention relates to solidification of liquid nonionic surfactants with a binder, carrier, or both binder and carrier to form a solidified surfactant composition. In particular, the invention relates to solidification of liquid nonionic surfactants utilizing drying device(s), wherein the feed composition contains at least one liquid nonionic surfactant and the binder, carrier, or binder and carrier to form a solidified surfactant composition. The solidified surfactant compositions can be useful in various cleaning compositions.

Abstract: A syringe pump configured to at least partially surround a syringe loaded into the pump. The syringe pump including a syringe pump housing defining a syringe receptacle shaped and sized to accept loading of the syringe, a plunger driver assembly configured to manipulate a plunger of a syringe loaded into the syringe pump, and a syringe housing including a syringe barrel shield pivotably coupled to the syringe pump housing configured to at least partially enclose a syringe loaded into the syringe pump within the syringe receptacle, and a syringe plunger tray and lid assembly operably coupled to the syringe pump housing and configured to at least partially enclose a portion of the plunger driver assembly.

Abstract: A system using combined electrocardiography (EKG) and photoplethysmography (PPG) sensing, to determine venous oxygen saturation is described. The system uses averaging of similar pulses based on Prior (or n?1) R-to-R pulse wave duration, and current (or n) R-to-R pulse wave duration for evaluation of the metabolic reserve and/or stress of the patient.

Abstract: Embodiments disclosed herein provide an organic matter processing apparatus and method for the use thereof to convert organic matter into a ground and selectively dried product. This can be accomplished using a bucket assembly that can grind, paddle, and heat organic matter contained therein. An algorithm is used to control the conversion of organic input to organic output by progressing through processing states based, in part, on time windows, runtimes, and sensor data. Motor operation can be observed to promote efficient grinding of the organic matter contained in the bucket assembly.

Abstract: Embodiments disclosed herein provide a user experience to interact with an organic matter processing apparatus (OMPA) that converts organic matter into a ground and dried shelf-stable product. The user experience can be accessed via an application that operates on a mobile device or a website. The application can be used to set an operational schedule of the OMPA, start or stop an OMPA processing cycle, observe a status of the OMPA, observe statistics related to the OMPA, request supplies, access a guide to assess whether certain organic matter can be safely added to the OMPA, and alert the user of potential issues with the OMPA.
