Adjustable vascular graft for custom inner diameter reduction and related methods

A prosthetic medical device having an adjustable configuration from a first diameter to a second diameter smaller than the first diameter along an adjustable length, wherein the second diameter is maintained in vivo following implantation in a body to create a flow restricted passage in the prosthetic medical device, the prosthetic medical device comprising:

• a tubular graft having open ends and a continuous outer wall circumscribing a lumen along a longitudinal axis, the outer wall having the first diameter at each of a proximal portion, a distal portion, and a middle portion, the middle portion having the adjustable length, the outer wall including at least two rows of receivers spaced apart in a circumferential direction along the adjustable length;
• and
• a suture passing through the rows of receivers to form a crossing pattern or a zig-zag pattern, the suture having a first free end and a second free end, wherein movement of the first free end and the second free end away from the rows of receivers transitions the adjustable length from a first configuration with the first diameter to a second configuration with the second diameter.
