Devices and methods for performing vascular anastomosis
First Claim
1. A device for delivering a member adapted to be secured to a patients'"'"' body tissue, the device comprising:
- a first component;
a second component mounted to the first component, the first and second components being relatively movable;
the first component being configured to removably support a member adapted to be secured to a patient'"'"'s body tissue;
the second component being configured to hold at least one needle carrying suture for securing the member to the body tissue;
wherein the first component is relatively movable with respect to the second component to move the member along the suture into contact with the body tissue.

Abstract
Devices and methods for performing vascular anastomosis. A needle passer is used to pass one or more needles through tissue to thread one or more lengths of suture through the tissue. The needle passer is operable using one hand and includes a handle supporting a shaft assembly carrying first and second sets of needles connected by lengths of suture. An actuator assembly uncovers the first set of needles, moves them into a radially extended position, and then passes them through tissue, for example, the wall of a patient'"'"'s aorta. The needle passer may be pistol-shaped with a trigger that is moved in one direction to sequentially uncover, radially extend, and move the first set of needles through the aorta around an aortotomy. The needles may then be pulled away from the patient to thread the suture through the tissue. A delivery device is used to deliver a member adapted to be secure to body tissue, such as a vascular conduit. The delivery device includes a shaft and a collar mounted for relative movement. The shaft supports a vascular conduit so that an end of the conduit is disposed against the collar. A sealing element may be positioned on the collar beneath the end of the conduit. The needles in the second set are removed from the needle passer and are placed through the conduit and sealing element and into the collar. The shaft is then moved through the collar to move the vascular conduit along the suture into contact with the aorta. The delivery device is then removed and the respective ends of each suture length secured to fix the end of the vascular conduit to the aorta.

4. A device for delivering a vascular conduit to body tissue located at an anastomosis site within a patient'"'"'s body, the device comprising:
-
a shaft having a proximal end and a distal end, a portion of the shaft being configured to support a vascular conduit adapted to be anastomosed to body tissue;
a collar disposed on the shaft, the shaft and collar being slidably movable with respect to one another, the collar having an area configured to hold at least one needle adapted to be passed through a vascular conduit supported by the shaft. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 19)

18. A method for delivering a member adapted to be secured to body tissue to a location adjacent the body tissue, the method comprising steps of:
-
placing suture through body tissue so that the suture extends away from the body tissue, the suture having an end which carries a needle;
providing a delivery device comprising first and second components mounted so as to be relatively movable;
positioning a member adapted to be secured to the body tissue on the first component;
placing the needle carried by the end of the suture into the second component; and
imparting relative movement to the first and second components to move the first component and the member along the suture to a location adjacent the body tissue. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)

27. An anastomosis system for securing a vascular conduit to a hollow body structure, the system comprising:
-
a needle passer comprising a shaft assembly supporting at least one length of suture secured to first and second needles, and an actuator for moving at least one of the needles through tissue of a hollow body structure to thread the length of suture through the tissue to permit an end of a vascular conduit to be attached to the tissue in fluid communication with the hollow body structure; and
a sealing element configured to be positioned against the end of the vascular conduit, the sealing element being formed of a material that is able to receive one of the first and second needles. - View Dependent Claims (28)

29. A method for anastomosing a vascular conduit to a hollow body structure so that the vascular conduit is in fluid communication with the interior of the hollow body structure, the method comprising steps of:
-
forming an opening in tissue of a hollow body structure so that the opening passes into an interior of the body structure;
positioning an end of a vascular conduit against the tissue; and
attaching the vascular conduit to the tissue so that the vascular conduit is in fluid communication with the interior of the hollow body structure, wherein a sealing element is used to enhance the attachment between the end of the vascular conduit and the tissue. - View Dependent Claims (30, 31)
