  • Publication number: 20250135082
    Abstract: This disclosure teaches a system and method for monitoring an extracorporeal blood circuit of a patient and identifying a needle dislodgement. The method includes identifying a potential needle dislodgement event based on changes in pressure of the extracorporeal blood circuit, searching for a heart rate of a patient by analyzing an optical backscatter signal from an optical sensor attached to the extracorporeal blood circuit or by analyzing a pressure signal representative of the pressure in the extracorporeal blood circuit, and verifying the potential needle dislodgement event is a needle dislodgement based on the absence of the heart rate.

  • Publication number: 20250064480
    Abstract: A surgical introducer system having an outer introducer sidewall extending along a longitudinal axis from a proximal introducer end to a distal introducer end, an inner introducer sidewall extending within the outer introducer sidewall along the longitudinal axis and forming an introducer passage extending in a distal direction from a proximal passage opening at the proximal introducer end to an introducer passage end wall located proximal to the distal introducer end, and an end wall passage extending from the introducer passage end wall towards the distal introducer end. The introducer end wall passage joins the introducer end wall at one or more end wall edges defining an axial stop ring configured to contact the distal tip of a navigation probe between the probe shaft and a terminal end of the distal probe tip at a line of contact to thereby prevent movement of the navigation probe in the distal direction.

  • Patent number: 11648693
    Abstract: A personal care product system having a stand and a handle is provided. The handle can be docked with the stand when not in use. The position of the handle relative to the stand is maintained by a docking magnet in the handle and a docking magnet in the stand. The stand includes a base having a stand resting plane and an opposing top surface. The handle extends upward from the opposing top surface of the stand and is tilted with respect to a vertical axis with a majority of the handle being unsupported. A handle resting plane intersects the stand resting plane at an included angle of less than 90 degrees, and an axis of polarity of the docking magnet in the handle intersects the handle resting plane at an included angle between 15 and 35 degrees to facilitate the tilted position of the handle.

  • Patent number: 11517347
    Abstract: An introducer system for use with a navigation probe. The introducer system has an introducer and a probe retainer configured to selectively connect to the introducer. The probe retainer includes a receiver configured to receive a navigation probe shaft and limit movement of the navigation probe shaft in the lateral direction. A first clamp and a second clamp are connected to the receiver with the receiver located between the first clamp and the second clamp. Each of the first clamp and the second clamp is selectively engageable with respective portions of the introducer sidewall to hold the receiver at a fixed location relative to the introducer. The receiver, the first clamp, and the second clamp are configured to provide a visual path through the probe retainer and into the introducer passage.

  • Patent number: 11476708
    Abstract: A personal care product system is provided. The personal care product system has a stand that has a first stand permanent docking magnet. A stand inductive charging coil is also positioned within the stand. A handle that has a first handle permanent docking magnet is removably mounted to the stand. A handle inductive charging coil is positioned within the handle. A handle flux guiding member is in close proximity to a surface of the first handle permanent docking magnet to direct a magnetic field away from the inductive charging coils.

  • Publication number: 20220032037
    Abstract: Improved securement devices for use with intracardiac blood pump assemblies are provided. The present technology provides securement devices that may be used with a sheath assembly (e.g., an introducer sheath assembly, repositioning sheath assembly), and which are configured to restrict movement of an object (e.g., the catheter of the pump assembly) within the sheath assembly except when a mechanism (e.g., button) of the securement device is actively being actuated (e.g., pressed, held, etc.).

  • Publication number: 20220001090
    Abstract: In one aspect, a method and system for detecting a change in fluid dynamics of a fluid flowing through an extra-corporeal circuit is disclosed, which includes establishing an acoustic wave resonance across a transverse dimension of at least a portion of a line associated with the extra-corporeal circuit through which the fluid flows, monitoring a phase signal of the resonant acoustic wave, and identifying occurrence of a change in fluid dynamics of the flowing fluid when the observed phase signal of the resonant acoustic wave indicates a deviation from the expected fluid flow signature. The change in fluid dynamics can be used to indicate a venous needle dislodgement event.

  • Patent number: 11045182
    Abstract: A surgical introducer system having a sidewall that forms an introducer passage, and a probe receptacle at the distal end of the introducer. The probe receptacle begins at a proximal end and terminates at a distal end with the proximal receptacle end being between the distal receptacle end and the proximal introducer end. The receptacle's inner surface tapers continuously from the proximal end to the distal receptacle end, with the lateral size being greater at the proximal receptacle end. The inner surface receives the distal tip of a navigation probe and restricts movement of the distal probe tip in the lateral direction, and the sidewall is spaced from the navigation probe shaft to allow the shaft to move in the lateral direction within the passage when the distal probe tip is positioned in the probe receptacle.
