The invention provides novel hemostasis, tissue barriers, wound healing and cosmetology materials based on biocompatible carboxymethylcellulose, and methods for their preparation and use thereof.

An implantable article comprising a dissolvable sponge derived from the mixture of chitosan, a first polysaccharide and a second polysaccharides. The polysaccharides have different number average molecular weight characteristics to enable the control of the mechanical features of the sponge.

The invention relates to biocompatible polymer gel compositions useful in facilitating and maintaining hemostasis. The biocompatible polymeric gel composition is comprised of (a) one or more than one polyanionic polymer, (b) one or more than one polycationic polymer, and (c) a solvent. A preferred composition includes sodium alginate, chitosan, and water to produce an adhesive hemostatic device that is useful in facilitating and maintaining rapid hemostasis.

The invention concerns methods of delivering a hydrogel to the heart, comprising: introducing a hydrogel composition into a subject, said hydrogel comprising components mixed prior to introduction; the introducing being performed such that the hydrogel composition resides between the epicardium and the pericardium of the subject. In some embodiments, the injection is performed using a syringe or catheter.

A composition for providing or maintaining a healthy skin microbiota and methods of providing or maintaining a healthy skin microbiota are disclosed. The composition can be a prebiotic composition that can include a carrier and a skin microbiota balancing agent. In some aspects, the skin microbiota balancing agent can include at least one combination of carbohydrate sources including a first carbohydrate source and a second carbohydrate source. The skin microbiota balancing agent can be configured to provide at least two of the following desired ratios: a first desired ratio of Corynebaderium to Staphylococcus of 1.3, a second desired ratio of Corynebaderium to Micrococcus of 1.4, and a third desired ratio of Staphylococcus to Micrococcus of 1.1. The carbohydrate sources may be D-alanine, D-threonine, L-alanyl-glycine, succinic acid, α-keto-glutaric acid, m-tantaric acid, bromo succinic acid, mucic acid, phenylethyl-amine, inulin, oxalic acid, pectin, Tween 40 etc.

In various embodiments, a tissue thickness compensator can comprise one or more capsules and/or pockets comprising at least one medicament therein. In at least one embodiment, staples can be fired through the tissue thickness compensator to rupture the capsules. In certain embodiments, a firing member, or knife, can be advanced through the tissue thickness compensator to rupture the capsules.
