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.

1. A system to effect a port, connection, or anastomosis of a portion of a blood vessel, duct, lumen or other tubular organ in the body of a living being by use of a connector assembly, said system comprising (i) a piercer-dilator instrument, (ii) an introducer sheath, and (iii) a deployment instrum
1. A system to effect a port, connection, or anastomosis of a portion of a blood vessel, duct, lumen or other tubular organ in the body of a living being by use of a connector assembly, said system comprising (i) a piercer-dilator instrument, (ii) an introducer sheath, and (iii) a deployment instrument, (a) wherein said piercer-dilator instrument comprises a proximal end and a distal end, and said piercer-dilator instrument is configured to form a small opening in the blood vessel, duct, lumen or other tubular organ to allow for the introduction of said introducer sheath,(b) wherein said introducer sheath comprises a proximal end, a distal end, and a hemostasis valve to atop flow of a fluid comprising blood, with said introducer sheath being arranged to facilitate introduction of said deployment instrument,(c) wherein said deployment instrument comprises said connector assembly, wherein said connector assembly comprises at least a first connecting member and an anchor member, with said members being arranged to be fixedly attached to each other, and said first connecting member comprises a tubular body having a central passageway therethrough, 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, thereby completing said port, connector, or anastomosis. 2. The system of claim 1, wherein said introducer sheath has a generally tubular body. 3. The system of claim 1, wherein said tubular body comprises a flange. 4. The system of claim 3, wherein said flange is annular. 5. The system of claim 4, wherein a small aperture extends radially outward from said central passageway of said first connecting member through said annular flange. 6. The system of claim 3, wherein said anchor member defines a hole therethrough. 7. The system of claim 6, wherein an outer diameter of said flange is just slightly larger than an inside diameter of said hole in said anchor member. 8. The system of claim 3, wherein said flange comprises a tab. 9. The system of claim 1, wherein an end of said tubular body opposite said flange comprises an undercut annular lip. 10. The system of claim 9, wherein an exterior surface of said undercut annular lip is chamfered. 11. The system of claim 1, wherein an outer surface of said tubular body is conical. 12. A system to effect a port, connection, or anastomosis of a portion of a blood vessel, duct, lumen or other tubular organ in the body of a living being by use of a connector assembly, said system comprising (i) a piercer-dilator instrument, (ii) an introducer sheath, and (iii) a deployment instrument, (a) wherein said piercer-dilator instrument comprises a proximal end and a distal end, and said piercer-dilator instrument is configured to form a small opening in the blood vessel, duct, lumen or other tubular organ to allow for the introduction of said introducer sheath,(b) 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 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, wherein the visibly exiting fluid gives an indication of location within said blood vessel, duct, lumen or other tubular organ, and wherein said passageway in said introducer sheath further comprises a cap or plug to stop the flow of said fluid,(c) wherein said deployment instrument comprises said connector assembly, wherein said connector assembly comprises at least a first connecting member and an anchor member, with said members being arranged to be fixedly attached to each other, and said first connecting member comprises a central passageway arranged for flow of the fluid therethrough, 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, thereby completing said port, connector, or anastomosis. 13. The system of claim 12, wherein said system further comprises an annular stop located near said distal end of said introducer sheath. 14. A system to effect a port, connection, or anastomosis of a portion of a blood vessel, duct, lumen or other tubular organ in the body of a living being by use of a connector assembly, said system comprising (i) a piercer-dilator instrument, (ii) an introducer sheath, and (iii) a deployment instrument, (a) wherein said piercer-dilator instrument comprises a proximal end and a distal end, and said piercer-dilator instrument is configured to form a small opening in the blood vessel, duct, lumen or other tubular organ to allow for the introduction of said introducer sheath,(b) 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,(c) wherein said deployment instrument comprises said connector assembly, wherein said deployment instrument further comprises a carrier tube having a proximal end and a distal end, with at least the distal end being open,wherein said deployment instrument further comprises a positioning member, with said first connector member and said anchor being disposed longitudinally in said carrier tube, prior to their deployment, wherein said connector assembly comprises at least a first connecting member and an anchor member, with said members being arranged to be fixedly attached to each other, and said first connecting member comprising a tubular body having a central passageway therethrough, 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, thereby completing said port, connector, or anastomosis,(d) said system further comprising a pusher-guide assembly located proximal to said anchor and said first connector member, wherein said pusher-guide assembly comprises a pusher-guide member and an actuation assembly, wherein said pusher-guide member comprises a central passageway, wherein said central passageway of said pusher-guide member is arranged to receive at least a portion of said actuation assembly. 15. The system of claim 14, 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, and wherein said actuation assembly further comprises an actuation cap mounted on the proximal end of said mandrel rod. 16. The system of claim 15, wherein said actuation cap comprises a proximal end and a distal end, and wherein a stop surface forms said distal end. 17. The system of claim 16, wherein said actuation assembly further comprises a helical compression spring extending around the outer periphery of at least a portion of said cylindrical mandrel rod, said spring being interposed between the proximal end of said pusher-guide member and said stop surface of said actuation cap.
