  • Patent number: 9492279
    Abstract: A bioabsorbable plug implant, suitable for bone tissue regeneration, includes a first portion, and a second portion extending outwardly from the first portion, the first and second portions formed from expandable material. A method for bone tissue regeneration includes providing a bioabsorbable plug implant, wherein the implant has a first portion and a second portion extending outwardly from the first portion. The first and second portions are formed from expandable material. The second portion is inserted into a defect or gap of a bone. The first surface engages the outside contour of the defect or gap. The plug implant is allowed to contact body fluids, thereby expanding the size of the plug implant so that the plug fits into the defect or gap.

  • Patent number: 9067017
    Abstract: There is provided a flow system of a dialysis device including a dialysate conduit which is capable of being in fluid communication with the peritoneal cavity of a patient's body and of being in fluid communication with a flow path, the flow path allowing dialysate to flow from a patient's body to a sorbent capable of removing contaminants within the dialysate in an outflow mode and in an inflow mode returning the dialysate substantially free of contaminants to the patient's body. The device also includes a pump for moving the dialysate along the flow path in both the outflow mode and inflow mode and a plurality of valves disposed along the flow path. There is also provided a portable dialysis device.

  • Patent number: 8071007
    Abstract: The invention relates to the use of Fused Deposition Modeling to construct three-dimensional (3D) bioresorbable scaffolds from bioresorbable polymers such as polycaprolactone (PCL), or from composites of bioresorbable polymers and ceramics, such as polycaprolactone/hydroxyapatite (PCL/HA). Incorporation of a bioresorbable ceramic to produce a hybrid/composite material support provides the desired degradation and resorption kinetics. Such a composite material improves the biocompatibility and hard tissue integration and allows for increased initial flash spread of serum proteins. The basic resorption products of the composite also avoids the formation of an unfavorable environment for hard tissue cells due to a decreased pH. The scaffolds have applications in tissue engineering, e.g., in tissue engineering bone and cartilage.
