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.
Claims14
An implantable vascular device comprising:
- a hollow cylindrical device body having two pairs of hollow nipples, extending from the exterior of the valve body and in fluid communication with the interior space of the device body, the device body further having a passageway between the exterior of the inner core and the interior of the device body;
- and
- a rotatable cylindrical inner core positioned within the device body between a first position and a second position, said inner core further including:
- a single channel passing through the inner core that positions the opposed pairs of nipples in fluid communication with each other, when the inner core is in the first position;
- a pair of openings;
- a first pair of conduits within the inner core are each in fluid communication with the pair of first openings in the inner core, when the inner core is in the first position, the first pair of conduits being further defined as being in fluid communication between said pair of first openings and hollow nipples when the inner core is in the first position;
- and
- a second pair of conduits within the inner core, each in communication with a second pair of openings within the inner core, the second pair of conduits also being joined in fluid communication by the passageway of the device body when the inner core is in the second position.
