Resorbable, macro-porous, non-collapsing and flexible membrane barrier for skeletal repair and regeneration

A resorbable, flexible implant in the form of a continuous macro-porous sheet is disclosed. The implant is adapted to protect biological tissue defects, especially bone defects in the mammalian skeletal system, from the interposition of adjacent soft tissues during in vivo repair. The membrane has pores with diameters from 20 microns to 3000 microns. This porosity is such that vasculature and connective tissue cells derived from the adjacent soft tissues including the periosteum can proliferate through the membrane into the bone defect. The thickness of the sheet is such that the sheet has both sufficient flexibility to allow the sheet to be shaped to conform to the configuration of a skeletal region to be repaired, and sufficient tensile strength to allow the sheet to be so shaped without damage to the sheet. The sheet provides enough inherent mechanical strength to withstand pressure from adjacent musculature and does not collapse.

Hardware for high strength fastening of bone

A high strength fastener for bone fractures. This fastener consists of two members, a male and female. The male member has external machine screw threads that screw into matching internal threads in the female member at a predictable torque so that the force of fixation exerted upon the bone can be approximated by the installer. Because of the effective length of the threads, this fastener is easily adjusted to the proper length without cutting. Both members have a smooth shoulder region proximal to the heads and this shoulder region presents a low-stress bearing surface to each cortical wall. Each member has a head that fits rigidly into an installation tool providing for ease of insertion and fastening in the patient with minimal invasion and little periosteal stripping. Each head has a semi-spherical face that articulates with matching washers and plates, thus allowing the washer to assume the plane of the surrounding bone therefore distributing the load over a greater area.

Self-anchoring slings and deployment mechanisms for use therewith in selectively positioning a sling into position within the body. According to a preferred embodiment, the sling comprises an elongate sling portion having opposed ends. Formed upon each respective opposed end is an anchor member operative to be advanced through soft tissue at a selected target site in a first direction but resist movement in an opposed direction. Such anchor members are operative to extend in opposed directions to thus enable a sling to be securely affixed into position and resist sag or otherwise lose its ability to support a given structure. The deployment system is operative to selectively anchor the respective anchor members into position within a tissue mass. Although suitable for a wide variety of applications, it is believed that the system and sling of the present invention are particularly well suited for the deployment of suburethral slings via a trans-obturator route.

Osseo-integrated sub-periosteal implant

A sub-periosteally implantable prosthesis support structure for a fixed or detachable dental prosthesis includes a framework fitted to and generally conforming to the inner and outer contours of the bony ridge structures of a person. The framework is configured to provide a space extending generally normal to the bony ridge structure to an apex to provide space for subsequent bone growth. A plurality of denture support posts are distributed about the framework and depend outwardly from the apex in substantial alignment with the bony ridge structure. During the fabrication of the prosthesis support structure, a bio-compatible fine mesh screen is fixed to and spans, tent-like, the framework to substantially overlay the bone structure and the space provided for subsequent bone growth. After the support structure has been implanted, the growth of bone into the space and around the support structure is promoted to osseo-integrate the support structure with the person's bony ridge, thus providing a secure foundation for a denture or fixed dental prosthesis configured for detachable or fixed coupling with the denture support posts. The support structure may be made, partly or wholly, from either non-resorbable material, such as titanium stock and mesh, or from a resorbable material such as Vicryl TM .

Adjustable implantable male incontinence device

An implantable, adjustable male incontinence device. The device has an inflatable balloon affixed to a central portion of a reinforced nonextensible elastomeric strip. The balloon includes a first length of elastomeric tubing extending therefrom that provides fluid communication with the interior chamber of the balloon. The uninflated balloon is implanted to overlie the male urethra with the nonextensible strip oriented horizontally and facing away from the urethra. The lateral opposing ends of the nonextensible strip are sutured to the periosteum of respective left and right iliac bones and the inflation port is implanted beneath the skin in an accessible portion of the body, preferably in the scrotum or, less preferably, in the perineum. The inflation port, which also includes a second length of tubing in fluid communication therewith, is implanted beneath the skin and the first and second lengths of tubing are connected to one another. A fluid is injected into the inflation port and conducted to the interior chamber of the balloon causing it to inflate and force periurethral tissue against the urethra to partially constrict the urethra and reduce the pressure of urine on the external meatus. The urethral constriction can be adjusted by increasing or decreasing the amount of fluid in the balloon via the inflation port.

Biosynthetic composite for osteochondral defect repair

ActiveUS20060195188A1Easy to integrateBone implantLigamentsOsseointegrationOsteochondral grafting
A composite for osteochondral defect repair includes a porous scaffold and a periosteal graft secured to a surface of the scaffold. The composite provides cartilage growth from autologous periosteum chondrogenesis. Biological resurfacing of large osteochondral defects, or a complete joint is feasible using the porous scaffold / autologous periosteal composite. The use of this composite eliminates the necessity of using normal cartilage surface as a donor site and its respective associated morbidity. In one form, the strong bone integration capacity of a porous metal (e.g., tantalum) scaffold and the high grade of integration observed from periosteal chondrogenesis into the normal cartilage eliminates the lack of chondral-chondral integration observed in the autologous osteochondral graft technique.

Resilient interpositional hip arthroplasty device

This disclosure is directed to a resilient interpositional arthroplasty implant for application into joints to pad cartilage defects, cushion joints, and replace or restore the articular surface, which may preserve joint integrity, reduce pain and improve function. The implant may endure variable joint compressive and shear forces and cyclic loads. The implant may repair, reconstruct, and regenerate joint anatomy, and thereby improve upon joint replacement alternatives. Rather than using periosteal harvesting for cell containment in joint resurfacing, the walls of this invention may capture, distribute and hold living cells until aggregation and hyaline cartilage regrowth occurs. The implant may be deployed into debrided joint spaces, molding and conforming to surrounding structures with sufficient stability to avoid extrusion or dislocation. Appendages of the implant may repair or reconstruct tendons or ligaments, and an interior of the implant that is inflatable may accommodate motions which mimic or approximate normal joint motion.
