Patent number: 12616501Abstract: 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.Type: GrantFiled: November 14, 2024Date of Patent: May 5, 2026Assignee: Vycor Medical, Inc.Inventors: Robert Schaefer, David Cantor

Publication number: 20250345504Abstract: 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.Type: ApplicationFiled: July 21, 2025Publication date: November 13, 2025Applicants: AWE Technologies LLC, Fresenius Medical Care Deutschland GmbH, Fresenius Medical Care Holdings, Inc.Inventors: Dipen N. SINHA, Robert SCHAEFER, Curtis OSTERHOUDT, Peter G. ESPINA, Martin J. CRNKOVICH, Fei WANG, Steve M. BOWMAN, Martin URBAN

Publication number: 20250235596Abstract: 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.Type: ApplicationFiled: April 8, 2025Publication date: July 24, 2025Applicants: AWE Technologies LLC, Fresenius Medical Care Holdings, Inc.Inventors: Robert SCHAEFER, Gareth T.

Patent number: 11517347Abstract: 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.Type: GrantFiled: January 13, 2020Date of Patent: December 6, 2022Assignee: Vycor Medical, Inc.Inventors: David Cantor, Robert Schaefer
