Patent number: 11724085Abstract: Systems and methods of disinfection of catheter connections are provided. A transfer catheter connector can include a UV-transparent window at its distal end and a sealing plunger proximal to the UV-transparent window. A solution set connector can be inserted inside a portion of the transfer catheter connector to connect a solution set and transfer catheter. The solution set connector comprises a lumen covered by a leading membrane surface; a sealing surface configured to sealingly engage the window surface, and a piercing member configured to pierce the membrane surface. The sealing plunger, membrane surface, and window define a disinfection zone. The connectors can be connected in a disinfection position configuration in which flow is not permitted between the catheters and the connectors are irradiated with UV light. After disinfection, the connectors are advanced to a flow position in which the piercing member pierces the membrane surface, enabling flow between the catheters.Type: GrantFiled: March 17, 2021Date of Patent: August 15, 2023Assignee: PURACATH MEDICAL, INC.Inventors: Justin A. Lance, Stephen Bower, John E. Ashley, Jeffrey Etter, Julia A. Rasooly, Michael Rasooly, Benjamin S. Arnett

Patent number: 11185603Abstract: Systems and methods of disinfection of catheter connections are provided. A transfer catheter connector can include a UV-transparent window at its distal end and a seal proximal to the window. A solution set connector can be inserted inside a portion of the transfer catheter connector to connect a solution set and transfer catheter. The solution set connector comprises a lumen covered by a leading membrane surface; and a sealing surface configured to sealingly engage the window surface. The connectors can be connected in a disinfection position configuration in which flow is not permitted between the catheters and the connectors are irradiated with UV light. After disinfection, the connectors are advanced to a flow position in which the piercing member pierces the membrane surface, enabling flow between the catheters. The system comprises clips that prevent advancement to the flow position without interference by the disinfection unit or by a user.Type: GrantFiled: July 11, 2017Date of Patent: November 30, 2021Assignee: PURACATH MEDICAL, INC.Inventors: Julia A.

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
