Patent number: 11229728Abstract: Methods and apparatus provide therapeutic electromagnetic radiation (EMR) for inactivating infectious agents in, on or around a catheter residing in a patient's body cavity and/or for enhancing healthy cell growth. Transmitting non-ultraviolet therapeutic EMR substantially axially along an optical element in a lumen of the catheter body and/or the catheter body. Through delivery of the therapeutic EMR to particular infected areas and/or areas requiring tissue healing. The inactivation of the major sources of infection in, on, and around catheters and/or enhance healthy cell growth around catheters is accomplished by utilizing controlled relative intensity and/or treatment region specific dosing of the therapeutic EMR emitted radially from the optical element. Specific embodiments of urinary catheters, peritoneal dialysis catheters, dialysis accesses, and hemodialysis accesses are also disclosed.Type: GrantFiled: August 24, 2020Date of Patent: January 25, 2022Assignee: Light Line Medical, Inc.Inventors: Mitchell D.

Patent number: 11090441Abstract: A syringe includes a barrel having an internal surface defining an internal bore therein; a plunger having a distal end disposed within the internal bore of the barrel, and a proximal end disposed outside the internal bore of the barrel; and a dose divider configured to bear on the barrel in response to translation of the plunger relative to the barrel along the longitudinal direction. The dose divider includes a base including a flange that extends at least partly in a radial direction; and at least one column extending away from the base along the longitudinal direction. The at least one column includes a proximal end and a distal end opposite the proximal end, the proximal end of the at least one column being coupled to the base. The at least one column includes a sacrificial portion coupled to a frangible link.Type: GrantFiled: August 23, 2016Date of Patent: August 17, 2021Assignee: TELEFLEX MEDICAL INCORPORATEDInventors: Huy Tran, Perry Croll

Publication number: 20070255167Abstract: An improved apparatus for monitoring the intra-abdominal pressure of a hospitalized patient includes a urinary catheter connected to a urine valve having selectable communication positions between a discharge end of the urinary catheter and either a drain or a fluid source. Preferably, the urine valve has a housing adapted to resist patient discomfort from leg-valve contact. One operable protective housing may be embodied as a separate tray component. Plumbing structure desirably maintains fluid supply and drain conduits in a substantially parallel arrangement to assist routing those conduits between a patient's legs. When the urine valve is oriented for communication to the fluid source, an infusion pump may be used to introduce a known quantity of fluid through the urine valve and into the patient's bladder where the fluid's pressure can be measured.Type: ApplicationFiled: July 3, 2007Publication date: November 1, 2007Inventors: Mark Christensen, Timothy Wolfe, Perry Croll, Marshall Denton, Edward Kimball

Publication number: 20070106226Abstract: An improved syringe with a sleeve operable as a barrier effective to resist entry of undesired particles, such as microorganisms or pathogens, for contact with the inside of the syringe from the plunger end. A portion of the sleeve is configured for disposition surrounding the plunger and inside the syringe's barrel. A syringe structured according to certain principles of the invention is effective to maintain the inside of the syringe's barrel in a sterile condition, even subsequent to multiple strokes of the plunger.Type: ApplicationFiled: November 9, 2005Publication date: May 10, 2007Inventors: Perry Croll, Mark Christensen, Marshall Denton

Publication number: 20070038143Abstract: An apparatus for monitoring the intra-abdominal pressure of a hospitalized patient includes a urinary catheter connected to a urine valve providing selectable communication between a discharge end of the urinary catheter and either a drain or a fluid source. Preferably, the urine valve is adapted for remote actuation and has a housing adapted to resist patient discomfort from leg-valve contact. Plumbing structure desirably maintains fluid supply and drain conduits in a substantially parallel arrangement to assist routing those conduits between a patient's legs. When the urine valve is oriented to permit communication with the fluid source, an infusion pump may be used to infuse a known quantity of fluid through the urine valve and into the patient's bladder. A pressure transducer desirably is connected in-circuit to indicate the fluid's pressure.Type: ApplicationFiled: August 9, 2005Publication date: February 15, 2007Inventors: Mark Christensen, Timothy Wolfe, Perry Croll, Marshall Denton, Edward Kimball
