Claim 0:
1. A branched anastomosis device (100), configured for minimally invasive implantation, the device (100) comprising:
a. a main channel (110) having an axis A (112), a proximal opening (114) at a proximal end (115), a distal opening (116) at a distal end (117), and a side opening (118) between the proximal and the distal ends;
b. a branch channel (120) having an axis B (122), a proximal opening (124) at a proximal end (125), and a distal opening (126) at a distal end (127), the proximal opening (124) of the branch channel (120) fluidly connected to the side opening (118) of the main channel (110);
c. a first collapsible ring (130), the first collapsible ring (130) coaxially disposed along axis A (112), inside the proximal opening (114) of the main channel (110);
d. a second collapsible ring (140), the second collapsible ring (140) coaxially disposed along axis A (112), inside the distal opening (116) of the main channel (110); and
e. a third collapsible ring (150), the third collapsible ring (150) coaxially disposed along axis B (122), inside the proximal opening (124) of the branch channel (120), wherein the third collapsible ring (150) comprises an angled barb (152) which interfaces with the main channel (110) and aligns with axis A (112) to set the angle (154) between the main channel (110) and the branch channel (120);
wherein axis A and axis B intersect to form an angle (154).
