Publication number: 20220362519Abstract: A catheter may include a tubular member having a lumen and an outer surface, a sleeve configured to be positioned in the lumen in a retracted configuration and to evert over at least a portion of the outer surface in an everted configuration, and a filament configured to retract the sleeve into the retracted configuration. The catheter may include an aperture proximal of a distal end, where the filament extends through the aperture from the lumen. A pull member may be on a distal end of the filament. The filament may be looped, coiled, and/or bunched in the catheter when the sleeve is in the retracted configuration. A shuttle may be attached to a distal end of the sleeve, where the shuttle includes a tubular member configured to maintain patency of the sleeve, and the filament engages the shuttle to retract the sleeve into the lumen.Type: ApplicationFiled: August 1, 2022Publication date: November 17, 2022Inventors: Morgan TIERNEY, Ronald John KELLY, David SCULLY, Aleksejus FOMINAS, David ROWE, Rodney W. DENLINGER, Adrian MAHON

Publication number: 20210402146Abstract: A catheter (700) includes a tubular member (702) having a lumen and an outer surface, a sleeve (704) configured to be positioned in the lumen in a retracted configuration and to evert over at least a portion of the outer surface in an everted configuration, and a filament (700) configured to retract the sleeve (702) into the retracted configuration. The catheter includes an aperture (774) proximal of a distal end, where the filament (770) extends through the aperture (774) from the lumen. A pull member (772) may be on a distal end of the filament (770). The filament (770) may be looped, coiled, and/or bunched in the catheter (700) when the sleeve (704) is in the retracted configuration. A shuttle (718) may be attached to a distal end of the sleeve (704), where the shuttle (718) includes a tubular member configured to maintain patency of the sleeve (704), and the filament (770) engages the shuttle (718) to retract the sleeve (704) into the lumen.Type: ApplicationFiled: November 13, 2018Publication date: December 30, 2021Inventors: Morgan TIERNEY, Ronald John KELLY, David SCULLY, Aleksejus FOMINAS, David ROWE, Rodney W.

Publication number: 20200391202Abstract: Systems and methods for detecting an infection are provided. A method of detecting an infection in a patient includes subcutaneously collecting a whole blood sample in a reservoir of the sampling device. The method further includes removing the reservoir, connecting the reservoir to a sample processor, and transferring the whole blood sample from the reservoir to the sample processor for processing. The method also includes connecting the sample processor to an analytical instrument and analyzing the processed sample via the analytical instrument.Type: ApplicationFiled: September 1, 2020Publication date: December 17, 2020Inventors: John C. VICTOR, David T. ROWE, Rodney W. DENLINGER, Victoria E. WAGNER, Michael A. BOUCHARD, Zheng ZHANG

Patent number: 10617344Abstract: A coupler for indicating the presence of a substance in blood is disclosed. The coupler includes a housing and a test strip. The housing has a proximal end and a distal end, and defines a hollow interior for receiving withdrawn blood. The test strip is held within the hollow interior of the housing. The housing removably couples with a medical instrument and a needle. The test strip produces a visible signal that indicates the presence or absence of the substance in the withdrawn blood. A kit including a syringe, a needle and the coupler is also disclosed.Type: GrantFiled: December 21, 2016Date of Patent: April 14, 2020Assignee: Teleflex Medical IncorporatedInventors: Nisha Gupta, David T. Rowe, Rodney W. Denlinger

Patent number: 9554736Abstract: The disclosure provides an allergy detection system for use during catheterization. The allergy detection system is incorporated into specialized syringes, connectors for use with standard syringes, or can be an independent test module designed for the sole purpose of allergy detection. The detection system features a test strip, such as an immunochromatographic test strip, and a structure to couple the system to a connector, syringe, or a housing, to form an independent test module. The detection system, by way of test strips, is used to detect potential allergic reactions.Type: GrantFiled: November 29, 2012Date of Patent: January 31, 2017Assignee: Teleflex Medical IncorporatedInventors: Nisha Gupta, David T. Rowe, Rodney W. Denlinger
