  • Haemostatic compositions
    Patent number: 11246958
    Abstract: A sterile, ready-to-use, flowable haemostatic composition comprises a soluble haemostatic agent comprising a plurality of carriers and a plurality of fibrinogen binding peptides immobilised to the carrier; a biocompatible liquid; and particles of biocompatible cross-linked polysaccharide suitable for use in haemostasis and which are insoluble in the biocompatible liquid. Such compositions may be used for the control of bleeding, especially in surgical procedures.
    Type: Grant
    Filed: May 11, 2016
    Date of Patent: February 15, 2022
    Assignee: HAEMOSTATIX LIMITED
    Inventors: Renata Zbozien, John Benjamin Nichols
  • Peptide dendrimers comprising fibrinogen-binding peptides
    Patent number: 10994047
    Abstract: Peptide dendrimers and agents are described, which can be used for polymerising fibrinogen and as haemostatic agents. The peptide dendrimers comprise a branched core, and a plurality of fibrinogen-binding peptides separately covalently attached to the branched core.

  • HAEMOSTATIC MATERIAL
    Publication number: 20180140737
    Abstract: Haemostatic materials are described, particularly haemostatic materials comprising an oxidised cellulose substrate covalently immobilised to a plurality of fibrinogen-binding peptides. Methods are described for covalently attaching fibrinogen binding peptides to oxidised cellulose substrates ad other substrates that have carboxyl groups on their surface.
