Devices and methods for assisting valve function, replacing venous valves, and predicting valve treatment success

An endograft valve device, comprising:

• an endograft body configured for expansion within a luminal organ, the endograft body comprising:
• a first portion having a proximal end defining a proximal end aperture and a distal end defining a distal end aperture, the first portion internally tapered inward from the proximal end to the distal end when the endograft body is expanded and configured to increase a velocity of fluid flowing therethrough;
• a second portion having a second portion proximal end defining a second portion proximal end aperture and a second portion distal end defining a second portion distal end aperture, wherein the distal end of the first portion is adjacent to the second portion proximal end and wherein the second portion is internally tapered inward from the second portion proximal end to the second portion distal end;
• and
• a valve portion positioned at or near the second portion proximal end or the distal end of the first portion, the valve portion configured to receive the fluid flowing through the distal end aperture of the first portion;
• wherein the endograft valve device is configured based upon a digital model of a luminal organ of a patient;
• wherein the digital model incorporates a vessel geometry input indicative of data obtained relative to a patient's venous geometry at a first location;
• and
• wherein the digital model further incorporates a flow velocity input indicative of data obtained relative to a flow velocity of blood within the vein of the patient.

• and
• a valve portion positioned at or near the second portion proximal end or the distal end of the first portion, the valve portion configured to receive the fluid flowing through the distal end aperture of the first portion;
• wherein the endograft valve device comprises a component of a valve system, the valve system further comprising a cuff configured to fit around a blood vessel and further configured to periodically compress the blood vessel;
• wherein the endograft valve device is sized and shaped to fit within the luminal organ, the size and shape based upon data obtained relative to a flow velocity of blood within a vein of a patient;
• wherein the valve system further comprises a processor operably coupled to the cuff, the processor configured to control a compression rate and a relaxation rate;
• wherein when the cuff is positioned around the blood vessel at a second location, operation of the processor causes the cuff to compress the blood vessel and relax compression of the blood vessel, whereby relaxation at the relaxation rate increases a rate of blood flow through the blood vessel at the second location;
• and
• wherein when the endograft valve device is positioned within the blood vessel at a first location and wherein when the cuff is positioned around the blood vessel at the second location, operation of the cuff increases the rate of blood flow through the blood vessel at the first location and the second location.
