Joint repair using mesenchymal stem cells
A method of repairing and/or stabilizing a joint by administering mesenchymal stem cells to the joint. Such a method provides for the regeneration of cartilaginous tissue in the joint, including meniscal tissue.
Implant pellets and methods for performing bone augmentation and preservation
Embodiments described herein are related to pellets that are placed within an extraction site that is in need of bone augmentation and preservation. The pellets are typically cylindrical in shape and comprise a material and a polymer coating. The goal of the pellets are to encourage sufficient new bone growth that jaw bone deterioration is prevented. The pellets create, arrange, and assemble an ideal growth environment for new bone growth to rapidly grow and preserve the original contours of an individual's jaw bone.
Instruments and methods for loading cells into implantable devices
Embodiments herein describe tools, instruments and methods for aseptic loading, dispensing and/or delivering cells into an implantable device and aseptically and selectively sealing a device inside a sterile package as well as and storing and preparing for shipment the cell-filled device.
Artificial urinary sphincter system
An artificial urinary sphincter (AUS) system includes a cuff, a pump, and a single tube that provides the system with an inflatable storage compartment. The single tube is connected between the cuff and the pump and includes a first lumen communicating between the cuff and the pump and a separate second lumen communicating between the cuff and the pump. The cuff is inflatable with a cuff volume of liquid that is sized to selectively close the urethra for treatment of urinary incontinence. The pump is operable to move the cuff volume of liquid out of the cuff to provide the cuff with a deflated state that allows the urethra to open and pass urine. The second lumen has a storage compartment sized to retain the cuff volume of liquid.
Implantable bioartificial perfusion system
The disclosure provides an implantable bioartificial active secretion system for providing a physiological regulating secretion such as insulin necessary for functionality of a physiologic activity such as glucose metabolism of a living-being host. The system includes a housing implantable within the host, in fluidic communication with tissue fluid indicative of a physiological regulating secretion need. A chamber within the housing contains a plurality of physiologically active, autonomously functioning, live secretory cells for producing the physiological regulating secretion. A continually operating two pump apparatus moves tissue fluid into contact with the secretory cells for pick up of the physiological regulating secretion for subsequent physiologically-effective dispensing into the host, while avoiding immuno-rejection of the host body or of the host to the secretory cells.
BIOMEDICAL PATCHES WITH ALIGNED FIBERS
A structure of aligned (e.g., radially and/or polygonally aligned) fibers, and systems and methods for producing and using the same. One or more structures provided may be created using an apparatus that includes one or more first electrodes that define an area and/or partially circumscribe an area. For example, a single first electrode may enclose the area, or a plurality of first electrode(s) may be positioned on at least a portion of the perimeter of the area. A second electrode is positioned within the area. Electrodes with rounded (e.g., convex) surfaces may be arranged in an array, and a fibrous structure created using such electrodes may include an array of wells at positions corresponding to the positions of the electrodes.

CONNECTIVE TISSUE BODY FORMATION SUBSTRATE AND SUBSTRATE REMOVAL TOOL
The present invention provides a connective tissue body formation substrate which can form a film-like connective tissue having a desired thickness and both surfaces in a desired surface condition without prolonging the time required for formation of the connective tissue. Specifically, two tissue formation surfaces 2a and 2b are faced with each other with a tissue formation space 3 being interposed therebetween. A slit 9 is formed in the tissue formation surface 2b so that the tissue formation space 3 communicates with an outside of the substrate. A connective tissue body formation substrate 1 is installed in an environment where a biological tissue material is present. A connective tissue intrudes into the tissue formation space 3 from the slit 9. Both surfaces of the film-like connective tissue are formed so as to match the substrate surface.

Polymer nanofiber scaffolds and uses thereof
A polymer nanofiber scaffold includes a plurality of melt extruded nanofibers that are chemically modified to append surface functionality to the nanofibers.
