MICRONIZED HYDROPHILIC CROSS-LINKED BIOPOLYMER SYSTEMS AND METHOD OF MAKING SAME
Disclosed are micronized hydrophilic systems of highly concentrated, cross-linked biopolymers. The system is created by combining a biopolymer with a cross-linking agent under mechanical kneading and allowing the biopolymer to undergo a cross-linking process followed by purification, drying and milling. The resulting micronized biopolymer system has an increased biopolymer concentration and increased longevity within the body.
Atraumatic detection/stimulation microlead
An atraumatic detection/stimulation lead is disclosed. The lead includes at least one microcable having a core cable comprising a plurality of elementary metal strands. One of the microcables has provided at its distal end an atraumatic protection device. The atraumatic protection device includes a protective coating on the distal ends of the elementary strands of the microcable, and the protective coating is covered by a protective cap of deformable material. The protective cap may be a conical distal end adapted to deform and axially flatten out. The microcable may have an overall diameter less than or equal to 1.5 French (0.50 mm).
Materials For Soft And Hard Tissue Repair
Biomaterials and methods and uses for repair or augmentation of tissues are provided. In particular, the invention provides a multi-layered, naturally occurring multi-axial oriented biomaterial comprising predominately type I collagen fibers. The invention further provides methods and uses for repair or augmentation of tissues using biomaterials of the invention.
Functionalized titanium binding peptides and implants coated with same
An isolated peptide is disclosed. The peptide comprises a titanium oxide binding amino acid sequence connected to a heterologous biologically active amino acid sequence via a beta sheet breaker linker, wherein: (i) the titanium oxide binding amino acid sequence is selected to bind coordinatively with titanium oxide; (ii) the titanium oxide binding amino acid sequence is selected to induce a beta sheet structure; and (ii) the titanium oxide binding amino acid sequence binds to titanium oxide with a higher affinity than said biologically active amino acid sequence binds to the titanium oxide under physiological conditions. Use of the peptides and titanium devices comprising same are also disclosed.
MATERIAL NON-ADHESIVE TO BIOLOGICAL SUBSTANCE, CURABLE COMPOSITION, AND ARTIFICIAL ORGAN AND MEDICAL INSTRUMENT USING SAME
A material non-adhesive to a biological substance containing: a polymer compound (A) which includes a repeating unit derived from a sulfobetaine monomer represented by Formula (I) or (II).
##STR00001##
In the formulae, R.sup.1 represents a methyl group, an ethyl group, an n-propyl group, or an isopropyl group, a plurality of R.sup.1's may be the same as or different from each other. R.sup.2 represents a hydrogen atom or a methyl group. n represents an integer of 2 to 4. L represents a linear or branched alkylene group having 3 or 4 carbon atoms.
Materials and Methods for Protecting Against Neuromas
The subject invention provides devices and methods for alleviating discomfort associated with neuroma formation. The devices and methods of the invention effectively use the body's natural response of reconstructing implanted biomaterials to minimize the size of, isolate, and protect a neuroma. In preferred embodiments, the subject device is a cylindrical cap, wherein the internal chamber of the cylindrical cap physically partitions the nerve to enable an arrangement of nerve fibers (as opposed to haphazardly arranged nerve fibers often produced in neuromas). Tabs arranged on the outside of the cap can be used to manipulate the cap into place on a nerve. The open end can also be configured with flaps that can be used to widen the open end for easier insertion of the nerve into the cap. In addition, the cap's material remodels into a tissue cushion after implantation, which protects the neuroma from being stimulated and inducing pain.

TISSUE FIBROSIS INHIBITOR IN WHICH BIOCOMPATIBLE POLYMER IS USED
A problem to be solved by the present invention is to provide a fibrosis inhibitor that solves the problem of inhibiting fibrosis of an organ or tissue surface, and especially of inhibiting fibrosis of an epicardial surface. Furthermore, by inhibiting fibrosis, the present invention prevents or reduces subsequent development of adhesions to avoid organ or tissue damage during re-operation. Provided is a fibrosis inhibitor for inhibiting fibrosis of a tissue by fixing a biocompatible polymer to a tissue where it is desirable to inhibit fibrosis.
Cell-Based Device For Local Treatment With Therapeutic Protein
The present invention provides a therapeutic device that comprises of mixture of cells secreting combination of therapeutic proteins, where cells producing therapeutic proteins are sealed in container which enables the exchange of nutrient and therapeutic proteins. The cells inside the therapeutic device produce and secrete certain amounts of therapeutic proteins. Cells are prepared by introducing genes encoding therapeutic proteins under the control of a constitutive or inducible promoter. The combination and concentration of therapeutic proteins is defined by the ratio of cells secreting different therapeutic proteins and/or by the gene expression ratio of the therapeutic proteins in the cells incorporated into the semi-permeable container. The therapeutic device can be used for treatments of various diseases and injuries for instance enhancement of wound healing and angiogenesis.
