C11589: Implantable Three-way Diaphragm ValveNovelty:
Biocompatible three-way valve features three points of access where only two of the three conduits are open at any given time. The invention facilitates permanent vascular access and allows cleaning of the device without exposure of the bloodstream.
Value Proposition:
About 300,000 patients undergo hemodialysis each year in the United States. The current options for permanent hemodialysis access (grafts and fistulas) require multiple surgeries and can lead to the loss of access site, stenosis development, or death. The invention has a novel three-way diaphragm valve designed to regulate fluid communication between a device and the bloodstream for patients requiring hemodialysis procedures. The design of the valve allows for external tubing to be flushed while the device is closed, thereby blocking access to the bloodstream. Advantages of this technology include:
• Valve is made of biocompatible materials
• Easy activation of diaphragm valve using positive and negative pressure
• Possible applications for modulation of other bodily fluids, such as cerebrospinal fluid
Technical Details:
Johns Hopkins researchers have created an implantable three-way diaphragm valve. By adjusting between positive and negative pressure, at any one time, only two of the three conduits are open. In the open state, the three-way valve allows for blood flow during dialysis procedure. When closed, the valve allows cleaning of the tubing with saline or another fluid, while protecting the bloodstream and preventing thrombus formation in the tubing.
Looking for Partners:
To develop and commercialize the technology as an implantable three-way valve for use with blood applications, such as hemodialysis vascular access.
