Bioresorbable embolization microspheres
The present disclosure is generally directed to an embolic material which, in some embodiments, may be in the form of a microsphere or a plurality of microspheres. The embolic material generally comprises carboxymethyl chitosan (CCN) crosslinked with carboxymethyl cellulose (CMC). In some embodiments, the embolic material may further comprise a therapeutic agent, such as doxorubicin.
METHOD OF APPLYING A SKIN BENEFICIAL AGENT TO AN ABSORBENT ARTICLE
Method of applying a skin beneficial agent to an absorbent article including a topsheet layer having a body facing surface and a garment facing surface, the article having a longitudinal front portion, a longitudinal back portion and a crotch portion located between the front and the back portion. The method includes at least the step of printing, by means of an in-line synchronized print technique, a water based ink composition including a binder and a microencapsulated skin beneficial agent on the article, the skin beneficial agent being at least a partly hydrophobic or lipophilic substance or additive, and the microcapsule material being water-insoluble at 20? C.
PRODUCT AND METHOD FOR TREATMENT OF BIOFILM, INCLUDING CONTROL OF SUBSTRATE COLONIZATION AND TREATMENT OF INFECTION
An antimicrobial product and methods of use are provided. The antimicrobial product includes a water-soluble antimicrobial organosilane and various additional compound, including antibiotic and anti-inflammatory medications, antiseptics, and/or detergents.

NANOFIBER-HYDROGEL COMPOSITES FOR CELL AND TISSUE DELIVERY
A soft tissue device can incorporate a composite material comprising a gel and at least one nanostructure disposed within the gel. A soft tissue device can further incorporate biologically active materials such as cells, tissues. A method for healing a soft tissue defect while promoting soft tissue regeneration can include applying a soft tissue device to a soft tissue defect, wherein the composite material includes a gel and a nanostructure disposed within the gel. A method for manufacturing a soft tissue device for use in healing soft tissue defects can include providing a gel, disposing nanofibers within the gel, and a biologically active material.
System and method for delivering protease inhibitors
The disclosed invention provides a system and method of artificially retarding fibrin-based blood clot degradation via the sustained release of a protease inhibitor, such as, for example, aprotinin or tranexamic acid (TA). The sustained release of the protease inhibitor is accomplished through incorporation within a biodegradable polymer microsphere to produce a protease inhibitor formulation. Next, the formulation along with fibrinogen and thrombin is applied to a wound site where an outer surface of the polymer microsphere degrades in a proteolytic environment to expose and release the incorporated protease inhibitor to the surrounding hydrogel or sealant or clot matrix at the wound site.
Superabsorbent composition with tannins for odor control
The present invention relates to a water-absorbing composition comprising water-absorbing polymer structures, on the surface of which is at least one tannin fraction which has a number-average molecular weight, determined in accordance with the test method described herein, of at least 1,000 g/mol, which has a weight-average molecular weight, determined in accordance with the test method described herein, of at least 1,000 g/mol, or which is a hydrolysable gallotannin. The present invention also relates to a process for the preparation of a water-absorbing composition, the water-absorbing composition obtainable by this process, a composite, a process for the production of a composite, the composite obtainable by this process, chemical products, such as, for example, hygiene articles, the use of a water-absorbing composition or of a composite and the use of a tannin fraction.
DRUG DELIVERY SHOCK WAVE BALLOON CATHETER SYSTEM
A catheter comprises an elongated carrier and a balloon carried by the carrier in sealed relation thereto. The balloon has an outer surface and is arranged to receive a fluid therein that inflates the balloon. The catheter further comprises a shock wave generator within the balloon that forms mechanical shock waves within the balloon, and a medicinal agent carried on the outer surface of the balloon. The medicinal agent is releasable from the balloon either before or in response to the shock wave.
Compositions and methods for macrophage conversion
The present invention describes methods and compositions of hydrogel microspheres for inducing macrophage conversion by sequentially converting a first population of wound macrophages in a wound to M2A macrophages by exposing the first population of wound macrophages to IL-4 and converting a second population of wound macrophages to M2C macrophages by exposing the second population of wound macrophages to IL-10. One aspect describes a method of inducing macrophage conversion in a wound. Another aspect describes compositions and methods of preparing a hydrogel microsphere for wound healing. Yet another aspect describes methods for treating a chronic wound with hydrogel microspheres.
