Abstract: A dental implant for anchoring in a jawbone to support an abutment for mounting a dental prosthesis is described. The dental implant comprises a collar portion located at an open proximal distal end, a mid portion integrally connected to the collar portion and a base hollow portion integrally connected to a mid portion and located at an open distal end of said implant. The collar portion has an axial opening that extends into a blind hole proceeding from the proximal end into the interior of the implant and is configured to secure the abutment to the dental implant. The mid portion includes external helical treads turning around an external wall of the mid portion. The base hollow portion comprises a wall defining an internal storage volume for an osseous tissue of the jawbone. The base hollow portion comprises a plurality of openings arranged in the wall and entering the internal storage volume. The base hollow portion is unthreaded and tapered with contraction towards the distal end.

Abstract: A vascular access device having a rotatable inner core positioned within a device body between first and second positions for diverting blood flow to an extracorporeal blood circuit. The previous version had two spouts under the skin while the improved device of the present invention uses four, since it connects to both artery and vein. The valve sits below and above the skin of the patient. When the valve is turned to treatment position, it sends the blood up to and from the dialysis machine. Another position of the valve allows for an antiseptic to clean the device. When not in use, blood continues to flow as usual.

Abstract: The present invention generally relates to the design and use of implantable medical devices, and in particular to the design and use of an implantable device for establishing long-term access to a patient's blood circulation for extra corporeal treatment of blood, such as hemodialysis, hemofiltration, oxygenation of blood and other. A vascular access device is provided having a rotatable inner core positioned within a device body between first and second positions for diverting blood flow to an extra corporeal blood circuit.
