Patent number: 11904111Abstract: Disclosed herein are catheter assemblies (100) with a locator tip (134) proximal to the distal tip (112) of a catheter tube (110). The locator tip is sized to remain outside a female urethra and configured to allow the catheter tube to pass there through. As an example, the locator tip allows a woman using a urinary catheter to target her urethra without exposing the catheter tube to tissue until the urethra is located and insertion is initiated. This avoids infecting the urethra with a catheter tube that has been contaminated by bacteria around the urethra.Type: GrantFiled: December 21, 2018Date of Patent: February 20, 2024Assignee: ConvaTec LimitedInventors: David A. Donnelly, Julie Lambrethsen, Melanie Clutton

Patent number: 11420017Abstract: A urinary catheter wetting apparatus (121) has a chamber defined by a forward section (123) opposite to a rearward section (125) each having an aperture (143,153) of which are axially aligned. A catheter tube is connected to a connector (161), the latter of which spans the chamber and initially seals the two apertures. The connector is slideable through the first facial surface (129) of forward section and the second end wall (131) of the rearward section so the catheter tube can be drawn through the chamber. A wetting applicator (151) holding a wetting agent is disposed in the chamber. Upon use, the connector passes through the chamber, applying pressure to the wetting applicator, thereby releasing the wetting agent from the wetting applicator and onto the catheter tube as it follows the connector through the chamber.Type: GrantFiled: December 28, 2018Date of Patent: August 23, 2022Assignee: CONVATEC LIMITEDInventors: Gareth J.
