Designer collagens and use thereof

The present disclosure provides synthetic collagen and methods of making and using synthetic collagen that include a synthetic collagen that facilitates wound closure comprising an isolated and purified triple helical backbone protein that facilitates wound closure comprising one or more alteration in a triple helical backbone protein sequence, that stabilize the isolated and purified triple helical backbone protein and does not disrupt an additional collagen ligand interaction; and one or more integrin binding motifs, wherein the isolated and purified triple helical backbone protein facilitates wound closure.

Compounds and matrices for use in bone growth and repair

Compositions of small molecules, matrices, and isolated cells including methods of preparation, and methods for differentiation, trans-differentiation, and proliferation of animal cells into the osteoblast cell lineage were described. Examples of osteogenic materials that were administered to cells or co-cultured with cells are represented by compounds of Formula II, IV, and VI independently or preferably in combination with a matrix to afford bone cells. Small molecule-stimulated cells were also combined with a matrix, placed with a cellular adhesive or material carrier and implanted to a site in an animal for bone repair. Matrix pretreated with compounds of Formula II, IV, and VI were also used to cause cells to migrate to the matrix that is of use for therapeutic purposes.

Biofilm resistant medical implant

A method of incorporating silver and/or copper into a biomedical implant includes: providing an implant having an outer surface; depositing silver and/or copper onto the outer surface of the implant; diffusing the silver and/or copper into a subsurface zone adjacent the outer surface; and oxidizing or anodizing the implant after the diffusion step to form an oxidized or anodized layer that contains at least some amount of elemental silver, elemental copper or silver or copper ions or compounds.

Modified demineralized cortical bone fibers

Methods for making surgical implants (or grafts) for the repair of bone defects, and more particularly, surgical implants that include demineralized bone fibers, are disclosed. Also disclosed are methods for increasing the wettability and ensuring uniform density of such implants. The surgical implants have a wettability time of less than 5 minutes and a residual moisture content of less than 6% by weight, and they remain cohesive and retain their shape upon complete rehydration.

SURGICAL SUTURE HAVING EXCELLENT BIOCOMPATIBILITY AND LOW FRICTION, AND METHOD FOR MANUFACTURING SAME

The present invention relates to a surgical suture having excellent biocompatibility and low friction, and to a method for manufacturing same. The suture according to the present invention has excellent biocompatibility and low friction, thereby reducing pain that may occur in a patient during suturing and minimizing the occurrence of inflammation in cells at a suture site, and also has excellent contact properties with cells, thereby capable of being used for various medical and surgical operations.

Hydrophilic Medical Catheters
20230119743 · 2023-04-20 ·

This invention disclosed medical catheters with surface hydrophilic coatings. Said catheters were grafted with a thin layer of zwitterions, which forms lubricious water layer when contacted with human body liquids or other water solutions, to lower the surface friction and mechanical damage to human body. One benefit of the present invention is due to the excellent biocompatibility and tight bonding between modification material and catheter substrate, the modification will stably stay on the substrate during usage, to avoid the potential side effects caused by lubricants. This modification can be applied to multiple material surfaces, including but not limited to silicone rubber, polyurethane, rubber, polyetheretherketone, polyethylene, polypropylene, polyvinyl chloride, nylon, ABS (Acylonitrile Butadiene Styrene), and polycarbonate.
