DRY COMPOSITION FOR USE IN HAEMOSTASIS AND WOUND HEALING
The present disclosure relates to a dry composition which reconstitutes without mechanical mixing to form a flowable paste having a soft and light consistency suitable for use in haemostasis and wound healing procedures upon addition of an aqueous medium. The disclosure further relates to methods of preparing the dry composition, methods for reconstituting the dry composition and medical use of the composition.
Wound care compositions
Glass-based particles of a biocompatible material which comprises 40 to about 80 wt % borate (B.sub.2O.sub.3) intermixed into a carrier which is an ointment, cream, or surgical glue.
THERAPEUTIC POLYMER GEL SYSTEM TO PROMOTE HEALING AND PREVENT FIBROSIS AT A WOUND OR SURGICAL SITE
Disclosed herein are therapeutic polymer gel systems for promoting healing of a wound or surgical site in a subject. The therapeutic polymer gel forms a microporous network and may be applied or injected in a fluid form and annealed or crosslinked after application to the wound or surgical site. The microporous gel may optionally contain various therapeutic agents throughout the therapeutic polymer gel which are released.
A METHOD FOR DRYING HYDROGEL COMPRISING NANOFIBRILLAR CELLULOSE AND A DRIED HYDROGEL COMPRISING NANOFIBRILLAR CELLULOSE
The present disclosure relates to method for drying hydrogel comprising nanofibrillar cellulose, the method comprising providing a hydrogel comprising nanofibrillar cellulose, providing polyethylene glycol, providing trehalose, mixing the hydrogel, the polyethylene glycol and the trehalose to obtain a mixture, and freeze drying the mixture to obtain a dried hydrogel comprising nanofibrillar cellulose. The present disclosure relates to a freeze-dryable hydrogel comprising nanofibrillar cellulose, to a freeze-dried hydrogel comprising nanofibrillar cellulose, and to a medical hydrogel comprising nanofibrillar cellulose and one or more therapeutic agent(s).
Intraoperative Topically-Applied Non-Implantable Rapid Release Patch
A device for delivery of a therapeutic agent to a surgical cavity, including: a porous, mucoadhesive, freeze-dried polymeric matrix having first and second opposed surfaces, the matrix formed by a composition including chitosan; a plurality of particles embedded within the matrix, the particles containing the therapeutic agent and having a coating around the therapeutic agent, the coating including chitosan. The first surface of the matrix is configured to be applied to the surgical cavity; the device releases the particles through the first surface; the device is also sterilized and provides release of approximately 20% to 100% of the therapeutic agent within 20 minutes of application to the surgical cavity.
Scaffold compositions for tissue repair
The present invention relates to hemostatic scaffold compositions and the method of preparation thereof. In present invention, hemostatic scaffold compositions for wound care and dental care, uses chitosan and tranexamic acid.
Biomedical Foams
The invention relates, generally, to porous absorbent materials which are suitable for packing antrums or other cavities of the human or animal body. More particularly, it relates to hydrophilic biodegradable foams, which may be used e.g. in the form of a plug or tampon, for instance for controlling bleeding, wound closure, prevent tissue adhesion and/or support tissue regeneration. The invention provides an absorbent foam, suitable for packing antrums or other cavities of the human or animal body, comprising a biodegradable synthetic polymer, which polymer preferably comprises C(O)O groups in the backbone of the polymer, for instance polyurethane and/or polyester units combined with polyethers.
FORMED SHEET PRODUCT AND HEMOSTATIC MATERIAL
A formed sheet product of a polymer composition comprising at least one protein selected from the group consisting of fibrinogen and thrombin and at least one polymer selected from the group consisting of an aliphatic polyester and a water-soluble polymer, and a laminated formed sheet product comprising a first polymer composition layer composed of fibrinogen and a water-soluble polymer and a second polymer composition layer composed of thrombin and an aliphatic polyester are provided. These formed products are applied onto a wound site and function as a hemostatic material.
Methods and compositions for achieving hemostasis and stable blood clot formation
Provided is tunable biopolymer hydrogel produced from two processed natural polysaccharides for use as a hemostat. If desired, the hydrogel formation can be tuned so that the hydrogel forms within seconds when applied to a tissue lesion. The resulting hydrogel can adhere to tissue and, without swelling, produce hemostasis within seconds after application to tissue of interest. The hydrogel also captures, aggregates and concentrates platelets and red blood cells at the site of the tissue lesion thereby initiating a clotting cascade at the site of the lesion. The hemostat can be used to prevent blood loss during surgical procedures, for example, during brain, spine or other surgical procedures where hemostasis is desirable, and is particularly useful during surgical procedures where swelling of the hemostat (e.g., in the brain or spine) would be detrimental to the subject.
Enhanced medical dressing apparatus, system, and method
An enhanced medical dressing for treatment of wounds is provided. A dressing is augmented by one or more enhancers thereon. The enhancers include a collagen, an antibiotic, or both. The enhanced medical dressing is prepared by placing and mixing the collagen, the antibiotic, and the dressing within a container. On mixing, the enhanced medical dressing is formed such that the enhancer adheres to the dressing by, for example, adsorption or an electrostatic force. The enhanced medical dressing when applied to the wound causes the collagen and the antibiotic to be released into the wound. Further, the enhanced medical dressing degrades over time due to contact with physiological moisture.
