A fastening device for clamping and fastening tissue together with fasteners formed from an adhesive is disclosed. An embodiment of the adhesive fastening device can clamp a first and a second portion of tissue together between a first and a second jaw, and can place a fluid polymer adhesive into tissue and form it into a polymerized surgical fastener within the tissue. The adhesive fastener can be formed as a polymerized shank or shaft extending through the tissue, and can have one or more heads formed on the shank. The shank can be formed solely from the polymerizable adhesive, or can be formed from another material such as nitinol, titanium, stainless steel, suture, or a plastic. Shanks of other material can be combined with the adhesive. Alternately, an adhesive fastener can be formed extending distally from a distal end of the surgical device. And, an adhesive fastener can be formed around a luminal tissue or within luminal tissue.

What is claimed is: 1. A surgical device for forming adhesive fasteners in one or more portions of tissue comprising: a) a shaft; b) a first jaw extending from a distal end of the shaft and a second jaw at the distal end of the shaft, the second jaw movable from a first position spaced away from the first jaw to a second position adjacent to the first jaw to clamp tissue therebetween, wherein the first jaw has a first head forming pocket, wherein the second jaw has a second head forming pocket; c) a fluid polymer adhesive contained within the surgical device, the fluid polymer adhesive polymerizable by exposure to an adhesive initiator; and d) a fastener forming end effector configured to form an adhesive pin fastener in tissue with the fluid polymer adhesive, wherein the fastener forming end effector is operable to form the adhesive pin by dispensing part of the fluid polymer adhesive in the first head forming pocket and part of the fluid polymer adhesive in the second head forming pocket, such that the adhesive pin fastener has two heads adjacent to opposite surfaces of the clamped tissue, wherein at least a part of the adhesive pin fastener is formed by shaping the fluid polymer adhesive while the end effector is in contact with the one or more portions of tissue, and polymerizing the fluid polymer adhesive by exposing the shaped fluid polymer adhesive to the adhesive initiator. 2. The surgical device of claim 1 wherein the fastener forming end effector is connected to a pump comprising a piston in a bore for dispensing the fluid polymer adhesive from within the surgical device and into contact with the one or more portions of tissue. 3. The surgical device of claim 2 wherein the adhesive initiator is one selected from the group consisting of tissue contact, visible light, ultraviolet radiation, heat, moisture, and polymerization initiating compounds. 4. The surgical device of claim 3 wherein the adhesive initiator is a polymerization initiating compound on at least a portion of the first jaw and the second jaw. 5. The surgical device of claim 1 further including a hollow needle filled with the adhesive reciprocatably mounted within the shaft and operably coupled to the fastener forming end effector to penetrate the one or more portions of tissue clamped between the first jaw and the second jaw, wherein when the hollow needle penetrates the one or more portions of tissue, wherein the fastener forming end effector is operable to place the fluid polymer adhesive within the one or more portions of tissue to form the adhesive pin fastener therein. 6. The surgical device of claim 1 wherein the fastener forming end effector includes one or more hollow needles reciprocatably mounted within the first jaw to penetrate into and retract from the one or more portions of tissue clamped within the first jaw and the second jaws. 7. The surgical device of claim 6 wherein each of the one or more hollow needles have a sharp edge for coring a passage through the one or more portions of tissue and a hollow for storing the tissue remnants therein. 8. The surgical device of claim 7 wherein the one or more hollow needles have a reciprocating plunger within the hollow for ejecting the tissue remnants from each of one or more hollow needles the hollow needle and into one of the first head forming pocket and the second head forming pocket, the tissue remnants becoming encapsulated in the adhesive pin fastener when the fluid polymer adhesive is formed. 9. The surgical device of claim 8 wherein the one or more hollow needles and the plunger mounted within the hollow bends within the first jaw towards the second jaw to penetrate tissue clamped therebetween. 10. The surgical device of claim 6 wherein the one or more hollow needles have a distal point for penetrating tissue and the hollow is filled with the fluid polymer adhesive, wherein when the one or more hollow needles reciprocates to penetrate tissue, the fastener forming end effector dispenses the polymer adhesive from the one or more hollow needles to form a double headed adhesive pin fastener from each of the one or more hollow needles by forming the first fastener head within the first head forming pocket and forming an adhesive shank within the tissue and forming the second fastener head within the second head forming pocket. 11. The surgical device of claim 10 further comprising a knife operatively attached to the one or more hollow needles to penetrate into and cut tissue when the one or more hollow needles penetrate into and retract from the one or more portions of tissue clamped within the first jaw and the second jaws. 12. The surgical device of claim 11 wherein the knife is circular and the one or more hollow needles are in a circular array about the knife. 13. A surgical device for forming fasteners within one or more portions of tissue comprising: a) a shaft having a proximal and a distal end; b) fluid polymer adhesive contained within the shaft wherein the polymer adhesive is polymerized by exposure to an adhesive initiator; and c) a fastener forming end effector at a distal end of the shaft configured to form an adhesive pin fastener in the one or more portions of tissue with the fluid polymer adhesive, wherein the fluid polymer adhesive is shaped into the adhesive pin fastener from at least a portion of the distal end of the shaft and polymerized by exposing the shaped fluid polymer adhesive to the adhesive initiator, wherein the fastener forming end effector comprises two head forming features positionable on opposite sides of the one or more portions of tissue, wherein the fastener forming end effector is operable to dispense the fluid polymer adhesive into each of the two head forming features such that the adhesive pin fastener formed by the fastener forming end effector has two heads, each head being positioned on opposite sides of the one or more portions of tissue. 14. The surgical device of claim 13 wherein the adhesive initiator is one selected from the group consisting of tissue contact, heat, moisture, and polymerization initiating compounds. 15. A surgical device of claim 13 wherein the fastener forming end effector comprises at least one hollow needle reciprocatably reciprocally mounted within the shaft and filled with the fluid polymer adhesive, wherein reciprocation of the at least one hollow needle drives the hollow needle into tissue and retraction of the needle dispenses the fluid polymer adhesive into the one or more portions of tissue as the needle retracts. 16. A surgical device of claim 14 including a plunger within the at least one hollow needle for dispensing the fluid polymer adhesive from the at least one hollow needle during reciprocation of the hollow needle.
