  • Patent number: 11766511
    Abstract: The invention relates to extracorporeal blood circuits, and components thereof (e.g., hollow fiber membranes, potted bundles, and blood tubing), including 0.005% to 10% (w/w) surface modifying macromolecule. The extracorporeal blood circuits have an antithrombogenic surface and can be used in hemofiltration, hemodialysis, hemodiafiltration, hemoconcentration, blood oxygenation, and related uses.

  • Publication number: 20210268543
    Abstract: The invention features surfaces formed from a base polymer admixed with an additive of the invention. The surfaces can be resistant to bacterial adhesion. The surfaces of the invention can be applied to: (a) any medical device or material that is implanted in or juxtaposed to a human or animal tissue or body fluid, in vivo or ex vivo, permanently or for a short period, and (b) any useful article, material or device, medical or not, which is to maintain a human or animal health-safe unfouled state of cleanliness over a period of time. In these medical and non-medical applications it is known that undesirable fouling phenomenon can take place which might harm a patient, user or consumer of the compromised device, equipment or material processed by, transported or stored in contamination prone articles, equipment or environments. Such fouling phenomena include biofilm development and bacterial colony development.

  • Publication number: 20190142317
    Abstract: Disclosed are implantable glucose sensors having a biostable surface. The implantable glucose sensor includes a glucose detector and an enclosure defining a boundary between an internal space and an external space. The enclosure includes a semipermeable biointerface film containing a base polymer and a biostabilizing additive. The semipermeable biointerface film has a biostable surface and is permeable to glucose. The working electrode is disposed inside the internal space, and the biostable surface faces the external space or faces both the internal and the external spaces. Also disclosed are methods of preparation of the semipermeable biointerface films adapted for use in the implantable glucose sensors. Further, disclosed are methods of monitoring glucose levels in a subject through the use of an implantable glucose sensor. The implantable glucose sensor may be an implantable electrochemical glucose sensor, in which the glucose detector is a working electrode.
