Publication number: 20210322753Abstract: Disclosed herein are devices and methods related to UV disinfection of a transfer catheter during peritoneal dialysis. The transfer catheter comprises a first and second end, the second end comprising a transfer valve. The transfer valve body comprises an inlet, outlet, and a flush hole. The valve core comprises a notch configured to allow fluid flow between the various flow paths. The valve core and body are positioned off axis with respect to the fluid flow path. The transfer catheter can allow for a small volume kill zone, which can minimize the amount of UV required to disinfect the catheter.Type: ApplicationFiled: May 7, 2021Publication date: October 21, 2021Applicant: PuraCath Medical, Inc.Inventors: Douglas MURPHY-CHUTORIAN, James R. KERMODE, Justin A. LANCE, Julia A. RASOOLY, Michael RASOOLY, Charles Martin SCHWIMMER

Patent number: 8794929Abstract: The present invention provides a fluid delivery system having a first chamber, a second chamber and a third chamber; a flow-through pump element separating the first chamber from the second chamber; a moveable pump element separating the second chamber from the third chamber; a first outlet in communication with the third chamber; and second outlet in communication with the second chamber. Additionally, the present invention provides methods of operating a fluid delivery system having a first chamber, a second chamber and a delivery chamber by reducing the volume of the second chamber while increasing the volume of the delivery chamber without operation of a flow-through pump element that separates the second chamber from the first chamber.Type: GrantFiled: November 22, 2006Date of Patent: August 5, 2014Assignee: Eksigent Technologies LLCInventors: Deon Stafford Anex, Charles Martin Schwimmer, David Laurence Black, Richard Dean Rush, Michael James Gearhart

Patent number: 8152477Abstract: One embodiment of the present invention provides a piston assembly having a piston housing filled with an electrolyte; a housing within the piston housing that divides the piston housing into a first portion and a second portion, the housing having apertures, a shaft connecting the housing to a piston head outside of the piston housing; and a porous material inside of the housing in contact with the electrolyte. Additionally, there are provided a method for filling the delivery chamber with a delivery fluid by withdrawing the piston head from within the delivery chamber. Yet another embodiment provides a method for filling a fluid delivery assembly by withdrawing a shaft from within the fluid delivery assembly to simultaneously displace a moving pump element within the delivery chamber and bypass fluid around a housing in the pump chamber.Type: GrantFiled: November 22, 2006Date of Patent: April 10, 2012Assignee: Eksigent Technologies, LLCInventors: Deon Stafford Anex, Charles Martin Schwimmer, David Laurence Black, Richard Dean Rush, Michael James Gearhart
