Hybrid prosthesis and delivery system

1 . A method for implanting a hybrid endoprosthetic device in an aorta of a patient, comprising the steps of:

a) anastomizing a branch of a branched tubular body of a hybrid endoprosthetic device of an endoprosthetic delivery device system to a side of a first iliac artery distal to an aneurysm site or a dissection site in the aorta of the patient to thereby admit blood into and displace air from a first tubular limb of the hybrid endoprosthetic device, wherein the branched tubular body has a first tubular body portion defining a longitudinal axis and a bifurcated branch tubular body portion extending along the longitudinal axis from the first tubular body portion;

b) closing the branch from the hybrid endoprosthetic device;

c) forming a purse-string suture in the aorta of the patient;

d) directing a stented tubular part of the hybrid endoprosthetic device of the hybrid endoprosthetic delivery device system through the purse-string suture and proximally into the aorta;

e) retracting a removable sheath through a hub at an access branch of the hybrid endoprosthetic device that is in communication with the stented tubular part, thereby releasing the stented tubular part from compact restraint by the removable sheath;

f) retracting a delivery shaft extending through the hub at the access branch;

g) clamping the access branch proximal to a distal tip of the shaft to thereby isolate the shaft from a main lumen of the branched tubular body;

h) removing the delivery shaft and the hub from the access branch;

i) de-airing the hybrid endoprosthetic device through one of a plurality of tubular branches;

j) attaching distal ends of each of the plurality of tubular branches extending laterally from the branched tubular body to respective branch arteries extending from the aorta;

k) anastomizing a second tubular limb of the branched tubular body to a second iliac artery;

l) severing the first tubular limb from a side of the first iliac artery;

m) anastomizing the first tubular limb to an end of the first iliac artery;

n) opening the aorta at the aneurysm site or the dissection site of the patient and securing the hybrid endoprosthetic device within the patient;

o) transecting the aorta; and

p) anastomizing the transected aorta to a collar of the endoprosthetic device.

2 . The method of claim 1 , wherein the hub includes a splitter mechanism, and wherein retracting the removable sheath from the compactly restrained stented tubular part further comprises directing the removable sheath across the splitter mechanism to split the sheath longitudinally.

3 . The method of claim 1 , wherein removing the delivery shaft comprises cutting the access branch to remove the access branch and the delivery shaft.

4 . The method of claim 1 , wherein the stented tubular part comprises at least one hook and further comprising, after releasing the stented tubular part, using the at least one hook for retention of the stented tubular part in a selected position.

5 . The method of claim 1 , wherein the sheath is splittable and a strand is retrievable, passes within the splittable sheath, and is attached at a distal end of the splittable sheath, and wherein retracting the removable sheath comprises pulling the strand externally from a proximal end of the strand to split the sheath from the distal end to the proximal end of the sheath.

6 . The method of claim 1 , wherein the delivery device system comprises a stopper member and further comprising, after clamping the access branch, sliding the stopper member on the shaft toward the distal tip of the shaft to form a hemostatic seal within the access branch.

7 . The method of claim 1 , wherein one or more of the tubular branches comprise a distal closed end and wherein attaching distal ends of each of the plurality of tubular branches comprises selectively opening one or more of the tubular branches.

8 . The method of claim 7 , wherein the distal closed end of at least one of the tubular branches comprises removable sutures.

9 . The method of claim 1 , further comprising, after attaching distal ends of each of the plurality of tubular branches, closing the access branch.

10 . The method of claim 1 , wherein the hub includes a housing with separable parts, the separable parts fastened together about the delivery shaft.

11 . The method of claim 10 , wherein the hub housing separable parts include a fastener.

12 . The method of claim 11 , further comprising, releasing the fastener and separating the separable parts.

13 . The method of claim 1 , wherein de-airing the hybrid endoprosthetic device through one of the plurality of tubular branches comprises de-airing through the access branch.

14 . The method of claim 1 , wherein the stented tubular part further comprises at least one radiopaque marker.

15 . The method of claim 14 , further comprising, after releasing the stented tubular part, repositioning the stented tubular part guided by the at least one radiopaque marker.

16 . The method of claim 1 , wherein the collar is attached to the endoprosthetic device at a location where the stented tubular part extends from the branched tubular body.

17 . The method of claim 1 , wherein the access branch has a greater lumen dimension than each of the plurality of tubular branches.

18 . The method of claim 1 , further comprising maneuvering a control handle attached to one end of the delivery shaft remote from the distal tip.

19 . The method of claim 1 , wherein the delivery shaft is configured to receive a guide wire through wire guides positioned on the surface of the shaft.

20 . The method of claim 1 , wherein the stented tubular part has a sleeve defining a lumen, and ring stents at the sleeve.
