Publication number: 20140236063Abstract: In accordance with certain aspects of the present disclosure, a subcutaneous arteriovenous graft system is described. The system includes an arteriovenous graft having an arterial end and an opposite venous end, at least one of the arterial end and venous end including a support frame. The system further includes a first valve device positioned at the arterial end of the arteriovenous graft and a second valve device positioned at the venous end of the arteriovenous graft and an actuator in communication with both the first valve device and the second valve device, the actuator being configured to cause each valve device to open or close simultaneously.Type: ApplicationFiled: September 21, 2012Publication date: August 21, 2014Applicant: CREATIVASC MEDICAL, LLCInventor: David L.

Patent number: 8764698Abstract: An arteriovenous graft system is described. The arteriovenous graft system includes an arteriovenous graft that is well suited for use during hemodialysis. In order to minimize or prevent arterial steal, at least one valve device is positioned at the arterial end of the arteriovenous graft. In one embodiment, a subcutaneous arteriovenous graft system is described. The system includes an arteriovenous graft having an arterial end and an opposite venous end with a first valve device positioned at the arterial end of the arteriovenous graft and a second valve device positioned at the venous end of the arteriovenous graft. The system also includes an actuator having an accumulator. The actuator is in communication with both the first valve device and the second valve device and is configured to cause each valve device to open or close simultaneously. The accumulator assists in maintaining a generally constant pressure when the actuator causes each valve device to close.Type: GrantFiled: December 21, 2012Date of Patent: July 1, 2014Assignee: CreatiVasc Medical, LLCInventor: David L.

Patent number: 8578589Abstract: In general, the present disclosure is directed to a tubing attachment tool. The tubing attachment tool includes first and second frames pivotally joined to one another such that the first and second frames can pivot to an open position and a closed position. Each of the first and second frames have a first handle end and a second end distal to the first handle end with each second end including a tubing grasping element. Each tubing grasping element includes a first curved surface and a second curved surface. When the first and second frames are in a closed position the first curved surfaces of the tubing grasping elements are aligned adjacent to one another and the second curved surfaces of the tubing grasping elements are aligned adjacent to one another such that the first curved surfaces define a first opening capable of housing an open end of tubing for attachment and the second curved surfaces define a second opening capable of grasping a portion of tubing inserted therebetween.Type: GrantFiled: October 16, 2009Date of Patent: November 12, 2013Assignee: CreatiVasc Medical, LLCInventor: Frank V.

Patent number: 8211056Abstract: The present disclosure is directed to a device for locating a fistula. The device can include a first tine and a second tine each having a distal end and a proximal end with the first tine spaced a distance from the second tine sufficient for allowing a section of a fistula to fit therebetween. A compression member can be placed adjacent to the first tine and the second tine such that the compression member externally compresses and temporarily occludes a fistula thereby increasing blood pressure in a section of a fistula located between the first tine and the second tine.Type: GrantFiled: August 22, 2006Date of Patent: July 3, 2012Assignee: CreatiVasc Medical, LLCInventor: David L.

Patent number: 8114044Abstract: An arteriovenous graft system is described. The arteriovenous graft system includes an arteriovenous graft that is well suited for use during hemodialysis. In order to minimize or prevent arterial steal, at least one valve device is positioned at the arterial end of the arteriovenous graft. In one embodiment, for instance, the arteriovenous graft system includes a first valve device positioned at the arterial end and a second valve device positioned at the venous end. In one embodiment, the valve devices may include an inflatable balloon that, when inflated, constricts and closes off the arteriovenous graft. By minimizing or preventing arterial steal, other complications associated with arteriovenous grafts are also avoided. For instance, the present invention is also well suited to preventing arteriovenous graft thrombosis, eliminating dialysis needle hole bleeding, and eliminating or minimizing arteriovenous graft pseudoaneurism formation.Type: GrantFiled: February 27, 2006Date of Patent: February 14, 2012Assignee: CreatiVasc Medical, LLCInventor: David L.
