Compacted hemostatic cellulosic aggregates
11235085 · 2022-02-01 · ·

The present invention is directed to a hemostatic material comprising a compacted, hemostatic aggregates of cellulosic fibers. In some aspects, the hemostatic material further includes additives, such as carboxymethyl cellulose (CMC) or other polysaccharides, calcium salts, anti-infective agents, hemostasis promoting agents, gelatin, collagen, or combinations thereof. In another aspect, the present invention is directed to a method of making the hemostatic materials described above by compacting a cellulosic-based material into hemostatic aggregates. In another aspect, the present invention is directed to a method of treating a wound by applying hemostatic materials described above onto and/or into the wound of a patient.

Procoagulant peptides and their derivatives and uses therefor
09717820 · 2017-08-01 · ·

The present invention is directed to a hemostatic or tissue sealing material having (a) a peptide having a sequence SEQ ID NO: 1 or an amino acid analog sequence thereof, and (b) a scaffold for said peptide or amino acid analogue sequence. The scaffold is preferably hemostatic, such as a natural or genetically engineered absorbable polymer, a synthetic absorbable polymer, or combinations thereof. The natural or genetically engineered absorbable polymers can be selected from the group consisting of a protein, a polysaccharide, or combinations thereof.

Formulations for wound therapy

The present invention relates to novel formulations comprising a dry powder fibrin sealant comprised of a mixture of fibrinogen and/or thrombin, for use in the treatment of wounds or injuries, in particular for use as a topical hemostatic composition or for surgical intervention.

COLLAGEN MATRIX AND N-HYDROXYLSUCCINIMIDE FUNCTIONALIZED POLYETHYLENE GLYCOL STAPLE LINE REINFORCEMENT

Disclosed herein are surgical staple line reinforcement materials and methods of production and use thereof.

In situ forming hemostatic foam implants

Systems and methods related to polymer foams are generally described. Some embodiments relate to compositions and methods for the preparation of polymer foams, and methods for using the polymer foams. The polymer foams can be applied to a body cavity and placed in contact with, for example, tissue, injured tissue, internal organs, etc. In some embodiments, the polymer foams can be formed within a body cavity (i.e., in situ foam formation). In addition, the foamed polymers may be capable of exerting a pressure on an internal surface of a body cavity and preventing or limiting movement of a bodily fluid (e.g., blood, etc.).

Haemostatic compositions

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.

CROSS-LINKED POLYMERS AND IMPLANTS DERIVED FROM ELECTROPHILICALLY ACTIVATED POLYOXAZOLINE

A biocompatible, covalently cross-linked, polymer that is obtained by reacting an electrophilically activated polyoxazoline (EL-PDX) with a nucleophilic cross-linking agent is disclosed. The EL-PDX comprises m electrophilic groups; and the nucleophilic cross-linking agent comprises n nucleophilic groups, wherein the m electrophilic groups are capable of reacting with the n nucleophilic groups to form covalent bonds; wherein m≧2, n≧2 and m+n≧5; wherein at least one of the m electrophilic groups is a pendant electrophilic group and/or wherein m≧3; and wherein the EL-PDX comprises an excess amount of electrophilic groups relative to the amount of nucleophilic groups contained in the nucleophilic cross-linking agent. Biocompatible medical products and kits comprising the cross-linked PDX-polymers are also disclosed.

HEMOSTATIC DEVICES AND METHODS OF USE

An anchorage device is provided that is configured to surround an implantable medical device. The anchorage device includes a first component having a first substrate and a second component having a second substrate. The second component is positioned within the first component. One of the first and second substrates includes a hemostatic agent and the other of the first and second substrates includes an active pharmaceutical ingredient. Kits, systems and methods are disclosed.

PROCESSING METHODS OF SOLGEL-DERIVED BIOACTIVE GLASS-CERAMIC COMPOSITIONS AND METHODS OF USING THE SAME

Methods for processing and or removing organic residuals and or impurities from a solgel-derived bioactive glass-ceramic and compositions comprising solgel-derived bioactive glass-ceramics processed using these methods, are described.

CHEMICALLY FOAMING HEMOSTAT
20170319739 · 2017-11-09 ·

A chemically foaming hemostat may use a liquid gel, a dried gel, a dry powder, or a solid “plug” like medium including a foaming agent to stop bleeding. The hemostat also may introduce pharmaceuticals and/or other compounds into a wound to control/mitigate shock, calm the patient, administer antibiotics, administer anti-sepsis compounds, control infection, control sepsis, and/or mitigate pain. No foreign matter need be introduced in connection with use of a chemically foaming hemostat. This eliminates the need to surgically remove introduced foreign matter at a later time. Use of a chemically foaming hemostat also may reduce the likelihood of trauma that sometimes occurs when foreign matter is left in place inside a wound.
