A system and method of use for effecting the bypass or other anastomosis, connection, or port in a portion of a native blood vessel, duct, lumen or other tubular organ within the body of a living being. The system includes a connector assembly and a deployment instrument for carrying the device to the desired position within the vessel, duct, lumen or tubular organ. The system includes a piercer-dilator instrument to form an opening in the wall of the vessel, duct, lumen or tubular organ into which a connector assembly may be deployed by the deployment instrument. The connector assembly may be at least partially formed of a resorbable material and includes movable members for securing it to the tissue of the vessel, duct, lumen or tubular organ contiguous with the opening. Other components may be included in the device for expediting the procedure, with or without the use of sutures.

We claim: 1. A system to effect a port, connection, or anastomosis of a portion of blood vessel, duct, lumen or other tubular organ in the body of a living being by use of a connector assembly, said system comprising a piercer-dilator instrument, an introducer sheath, and a deployment instrument, w
We claim: 1. A system to effect a port, connection, or anastomosis of a portion of blood vessel, duct, lumen or other tubular organ in the body of a living being by use of a connector assembly, said system comprising a piercer-dilator instrument, an introducer sheath, and a deployment instrument, wherein said piercer-dilator instrument comprises a proximal end and a distal end, and said piercer-dilator instrument is arranged to form a small opening in said blood vessel, duct, lumen or other tubular organ to allow for the introduction of said introducer sheath, wherein said introducer sheath comprises a proximal end and a distal end, with said introducer sheath being arranged to facilitate introduction of said deployment instrument, wherein said deployment instrument comprises said connector assembly, wherein said connector assembly comprises at least a first connector member and an anchor member, with said members being separate and arranged to be fixedly attached to each other, and said first connector member comprising a tubular flanged member having a free end portion, and wherein at least a portion of said connector assembly is arranged to be deployed internal to said blood vessel, duct, lumen or other tubular organ, and wherein said anchor member is arranged to be engaged with an interior surface of said blood vessel, duct, lumen or other tubular organ, and wherein said free end portion is arranged to extend through said small opening in said blood vessel, duct, lumen or other tubular organ, the system further comprising a positioning member arranged to move a portion of the first connector member into cooperative engagement with the anchor member, and whereby said system is capable of establishing a port, connection or anastomosis of said blood vessel, duct, lumen or other tubular organ. 2. The system of claim 1, wherein at least a portion of said connector assembly comprises a resorbable material. 3. The system of claim 1, wherein said introducer sheath further comprises a hemostasis valve to stop fluid flow. 4. The system of claim 3, wherein said hemostasis valve is arranged to accept said deployment instrument therethrough. 5. The system of claim 1, wherein said piercer-dilator instrument further comprises an axial passageway in communication with said proximal and said distal ends of said piercer-dilator instrument, with said communication serving to allow fluid to visibly exit said piercer-dilator instrument. 6. The system of claim 5 wherein said visibly exiting fluid gives an indication of location within said blood vessel, duct, lumen or other tubular organ. 7. The system of claim 1, wherein said introducer sheath further comprises an axial passageway in communication with said proximal and said distal ends of said deployment instrument, with said communication serving to allow fluid to visibly exit said deployment instrument. 8. The system of claim 7 wherein said visibly exiting fluid gives an indication of location within said blood vessel, duct, lumen or other tubular organ. 9. The system of claim 1, wherein said distal end of said introducer sheath is open and said proximal end of said sheath is closeable by means of a hemostatic valve. 10. The system of claim 1 wherein said deployment instrument comprises a carrier tube having a proximal end and a distal end, with at least the distal end being open. 11. The system of claim 10 wherein said first connector member and said anchor are disposed longitudinally in said carrier tube, prior to their deployment. 12. The system of claim 11 wherein said anchor is disposed proximally to said first connector member. 13. The system of claim 11 further comprising a pusher-guide assembly located proximal to said anchor and said first connector member. 14. The system of claim 13, wherein said pusher-guide assembly has a proximal end and a distal end, and wherein said distal end is generally conical. 15. The system of claim 13, wherein said pusher-guide assembly comprises a pusher-guide member and an actuation assembly. 16. The system of claim 15 wherein said pusher-guide member comprises a central passageway. 17. The system of claim 16, wherein said actuation assembly comprises a cylindrical mandrel rod having a central passageway extending along its length between open distal and open proximal ends of said rod, and wherein further said central passageway of said rod communicates with said central passageway of said pusher-guide member. 18. The system of claim 1 wherein said connector assembly further comprises a washer arranged to prevent bleeding at said port, connection, or anastomosis. 19. The system of claim 18 wherein said washer comprises a hemostatic material. 20. The system of claim 19 wherein said hemostatic material is collagen. 21. The system of claim 1 wherein said positioning member is arranged to move said anchor member into engagement with tissue adjacent the small opening in the wall of the blood vessel, duct, lumen or tubular organ. 22. The system of claim 1, wherein said positioning member is arranged to move said free end portion of said first connector member out through the small opening in the blood vessel, duct, lumen or tubular organ. 23. The system of claim 1 wherein said positioning member comprises a filament. 24. The system of claim 1 wherein said first connector member, anchor member and positioning member are coupled together.
