  • SPLIT AND SIDE-PORTED CATHETER DEVICES
    Publication number: 20170203033
    Abstract: A catheter for use in medical applications is disclosed. The catheter comprises tubing with a tip hole at one end and an end portion at the other end. Fluid exits the catheter at the tip hole thereof. One or more alternative fluid pathway(s) are provided on the sidewall of the catheter to permit outflow of fluid medication from the catheter to ensure proper delivery of the medication to the intended target area, particularly when the tip opening is occluded or restricted for any reason.

  • Polymer membranes for continuous analyte sensors
    Patent number: 9693721
    Abstract: Devices and methods are described for providing continuous measurement of an analyte concentration. In some embodiments, the device has a sensing mechanism and a sensing membrane that includes at least one surface-active group-containing polymer and that is located over the sensing mechanism. The sensing membrane may have a bioprotective layer configured to substantially block the effect and/or influence of non-constant noise-causing species.

  • SILICONE BASED MEMBRANES FOR USE IN IMPLANTABLE GLUCOSE SENSORS
    Publication number: 20170086717
    Abstract: Membrane systems incorporating silicone polymers are described for use in implantable analyte sensors. Some layers of the membrane system may comprise a blend of a silicone polymer with a hydrophilic polymer, for example, a triblock poly(ethylene oxide)-poly(propylene oxide)-poly(ethylene oxide) polymer. Such polymeric blends provide for both high oxygen solubility and aqueous analyte solubility.
