Publication number: 20240108850Abstract: A urinary catheter and container. The urinary catheter can include a catheter shaft attached to a handle and a coating disposed on an outer surface of the catheter shaft. The coating can include a hydrogel, water and/or glycerin, and a polyethylene gylcol (PEG). The PEG can have a molecular weight equal to or less than 600, for example one or more of polyethylene glycol (PEG) 300 and PEG 400. The coating can be applied in a wet state and remain wet for an extended period of time in the container, thereby obviating the need for a lubricant, such as a water sachet or gel package, to accompany the catheter in the container. The container can include a gas impermeable foil material. The container can include an adhesive tab covering a perforated section, the adhesive tab including a pull loop.Type: ApplicationFiled: December 11, 2023Publication date: April 4, 2024Inventors: Zhihui Yin, David Fish, Tom Roberts

Publication number: 20240016653Abstract: An example fluid collection device includes a sheath at least partially defining a chamber sized and dimensioned to receive at least a portion of a penis of a user therein. The sheath includes a proximal end region defining an opening configured to receive at least a urethral opening of a penis and a distal end region opposite to the proximal end region. The sheath also includes a first layer and a second layer. The first layer includes at least a nonwoven fabric extending at least partially between the proximal end region and the distal end region. The second layer includes a fluid permeable multilayer fabric at least partially positioned between the first layer and the chamber.

Publication number: 20220287874Abstract: A targeted temperature management (TTM) system for providing a TTM fluid including a thermal pad is disclosed. The pad includes a fluid delivery conduit and a fluid return conduit extending continuously from the pad to the TTM module. Valves may be included in line with fluid delivery and fluid return conduits. The thermal pads include one or more conduit retention devices for binding the fluid conduits together. Methods of using the system are disclosed and include disposing a thermal pad in a storage configuring where the fluid conduits are wound together to form a coil, winding the fluid conduits together to form a coil, binding the windings together with a conduit retention device, and placing the coil underneath a stretchable band of the thermal pad.Type: ApplicationFiled: March 3, 2022Publication date: September 15, 2022Inventors: Ping Huang, Patrick Hudson Chancy, Zhihui Yin, Hannah Rose Kriscovich, Kevin A.

Patent number: 9662423Abstract: Methods for the deposition of silver-comprising films on nonconducting substrates, and, more particularly, to deposition of such films that are very thin, are provided. The surface of nonconducting substrates is modified with a superabsorbent polymer to increase silver deposition when compared to a non-modified surface. Also provided are films produced using a swelling agent, whereby porosity of the surface of the nonconducting substrate is increased, thereby permitting increased silver deposition when compared to an unmodified surface.Type: GrantFiled: February 19, 2014Date of Patent: May 30, 2017Assignee: C.
