The present invention provides a kit for preparing a composition for sealing a lung tract, comprising: (a) a first component comprising: (i) a fibrinogen solution, and (ii) prewet gelatin particles in an aqueous solution; and (b) a second component comprising: (i) a thrombin solution, and (ii) a dry gelatin powder; wherein the first and second components are stored separately and configured for mixing together to form a composition that is flowable and cross-linkable. The composition may be used to seal tissue tracts such as lung tissue tracts.

Kit for composition for tissue tract sealing

The present disclosure relates to a method for preparing a haemostatic composition comprising thrombin, the method comprising the step of reconstituting a dry thrombin directly in a paste, such as a paste comprising a biocompatible polymer. The haemostatic composition comprising thrombin may be prepared from a dry thrombin composition and a paste in a single step operation and be used for treatment of a wound.

Method for preparing a haemostatic composition

Exoskeletal devices or sleeves that can be used with the delivery tube of an applicator device to help dispense fluids, typically flowable biocompatible materials such as hemostatic agents, adhesives, or sealants, onto specific sites in the human body for a medical reason are disclosed. The exoskeletal devices or sleeves are rigid, pre-shaped, and snappably or slidably affixed to the delivery tube. The exoskeletal devices or sleeves do not come into contact with the flowable biocompatible fluid being dispensed, and they can be placed at any position along the delivery tube to address different application situations. Once the exoskeletal device or sleeve is in place, it can optionally be locked onto the delivery tube to prevent further sliding under stresses when pushed against tissue. Multiple exoskeletal devices or sleeves can also be used to achieve more complicated shapes for hard-to-reach anatomical sites.

Rigid reinforcing exoskeletal sleeve for delivery of flowable biocompatible materials

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.

Procoagulant peptides and their derivatives and uses therefor

The present invention is directed to hemostatic material containing compacted ORC powder comprising particles having an average aspect ratio from about 1 to about 18, wherein said compacted ORC powder have preferably been processed in a compaction device, such as a ball milled ORC powder. The present invention further relates to methods of making the hemostatic material and a method of treating a wound by applying the hemostatic powder onto and/or into the wound of a patient.

Oxidized regenerated cellulose hemostatic powders and methods of making

The present invention is directed to a reinforced absorbable multilayered hemostatic wound dressing comprising a first absorbable nonwoven fabric, a second absorbable woven or knitted fabric, thrombin and/or fibrinogen.

Reinforced absorbable multilayered hemostatis wound dressing

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 analog 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.

The present invention is directed to a hemostatic material comprising a scaffold and a galvanic particulate. The galvanic particulate comprises particles made of at least two dissimilar metals. The scaffold is preferably a biocompatible polysaccharide-based hemostatic, such as a chitosan or cellulosic based hemostatic like ORC.

Hemostatic materials and devices with galvanic particulates

The present invention includes both sterilized and unsterilized hemostatic compositions that contain a continuous, biocompatible liquid phase having a solid phase of particles of a biocompatible polymer suitable for use in hemostasis and which is substantially insoluble in the liquid phase, and a discontinuous, biocompatible gaseous phase, each of which is substantially homogenously dispersed throughout the continuous liquid phase, methods for making such compositions, medical devices that contain sterilized hemostatic compositions disposed therein and methods of making such devices.

Process of making flowable hemostatic compositions and devices containing such compositions

The present inventions includes a plurality of packed particles that contain interstitial pores, where the interstitial pores have a pore volume and a median pore diameter effective to provide improved absorption of physiological fluids or an aqueous media when placed in contact therewith, compared to a plurality of unpacked particles of the same material, where the particles are made of a biocompatible material and hemostatic agents and have an average diameter suitable for use in providing hemostasis to a site of a body of a mammal requiring hemostasis, hemostatic compositions containing such plurality of packed particles, methods of making such particles and compositions and medical devices suitable for delivering and containing the hemostatic plurality of particles and/or composition to a site of a body.

Hemostatic compositions and devices

The present invention is directed to processes of making flowable hemostatic compositions and devices that include the flowable hemostatic composition disposed therein, where a volume of a biocompatible liquid, a volume of a biocompatible gas, and an amount of solid particles of a biocompatible polymer are mixed together to form a substantially homogenous composition including a discontinuous gas phase and the solid particles substantially homogenously dispersed throughout a continuous liquid phase to form a flowable hemostatic composition, and the composition then transferred into a device suitable for applying the flowable hemostatic composition to a site of a body requiring hemostasis under conditions effective to maintain the substantially homogeneous dispersion of the gas phase and the solid particles throughout the liquid phase.

The present invention is directed to a hemostatic wound dressing that utilizes a fibrous, fabric substrate made from carboxylic-oxidized cellulose and containing a first surface and a second surface opposing the first surface, the fabric having flexibility, strength and porosity effective for use as a hemostat; and further having a porous, polymeric matrix substantially homogeneously distributed on the first and second surfaces and through the fabric, the porous, polymeric matrix being made of a biocompatible, water-soluble or water-swellable cellulose polymer, wherein prior to distribution of the polymeric matrix on and through the fabric, the fabric contains about 3 percent by weight or more of water-soluble oligosaccharides.

Hemostatic wound dressings and methods of making same

The present invention is directed to wound dressings that contain a fabric made from biocompatible polymeric fibers and having flexibility, strength and porosity effective for use as a hemostat, and a porous, polymeric matrix prepared from a biocompatible, water-soluble or water-swellable polymer dispersed through the fabric; and to methods of making such wound dressings.
