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.

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.

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.

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.

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.
