Abstract

An absorbable screw fastener and a method of firing with an applicator capable of applying a surgical fastener to tissue in order to form tissue connection to secure objects to tissue, the fastener including a body portion having a helical thread, a head portion disposed at the proximal end of the body portion. The head portion includes a driver receiving configuration on its outer surface. The screw fastener further includes a cannulated center lumen with an opening extending from the head portion through the longitudinal length of the body portion.

Claims

1. An instrument for firing a plurality of fasteners loaded therein into a surgical mesh overlying a target tissue site, the instrument comprising:

a handle assembly;

an elongate endoscopic distal portion supported on and extending from the handle assembly, the elongate endoscopic distal portion configured to retain the plurality of fasteners therein, the endoscopic distal portion defining a distal tip through which each fastener of the plurality of fasteners is dispensed; and

a crenellated tip projecting distally from the distal tip of the elongate endoscopic distal portion.

2. The instrument according to claim 1, wherein the instrument includes a driver subassembly disposed within the elongate endoscopic distal portion and movable relative to the endoscopic distal portion.

3. The instrument according to claim 1, wherein the elongate endoscopic distal portion includes an outer tube that is positioned to be urged to a distally advanced position.

4. The instrument according to claim 3, further including a pilot disposed within the outer tube, the pilot having a tapered surface on a distal end of the pilot.

5. The instrument according to claim 4, further including a plurality of fasteners loaded in the elongate endoscopic distal portion, wherein each fastener of the plurality of fasteners is cannulated, defining a lumen therethrough, and wherein the pilot extends through the lumen of each fastener.

6. The instrument according to claim 1, wherein the elongate endoscopic distal portion includes a fastener retainer dimensioned to receive at least one fastener of the plurality of fasteners.

7. An instrument for securing a surgical mesh overlying a target tissue site, the instrument comprising:

a handle assembly having a trigger mechanism;

an elongate endoscopic distal portion supported on and extending from the handle assembly, the elongate endoscopic distal portion defining a distal tip and including a crenellated tip projecting distally from the distal tip thereof; and

a plurality of fasteners loaded in the endoscopic distal portion, each fastener of the plurality of fasteners adapted to be dispensed through the distal tip of the elongate endoscopic distal portion and into the surgical mesh upon actuation of the trigger mechanism of the handle assembly.

8. The instrument according to claim 7, wherein the instrument includes a driver subassembly disposed within the endoscopic distal portion and being relative to the endoscopic distal portion.

9. The instrument according to claim 7, wherein the elongate endoscopic distal portion includes an outer tube positioned to be urged to a distally advanced position.

10. The instrument according to claim 9, further including a pilot disposed within the outer tube, the pilot having a tapered surface on a distal end of the pilot.

11. The instrument according to claim 10, wherein each fastener of the plurality of fasteners is cannulated defining a lumen therethrough, and wherein the pilot extends through the lumen of each fastener.

12. The instrument according to claim 7, wherein the endoscopic distal portion includes a fastener retainer dimensioned to receive at least one fastener of the plurality of fasteners.

13. An instrument for securing a surgical mesh overlying a target tissue site, the instrument comprising:

an elongate endoscopic distal portion configured to retain a plurality of fasteners therein, the elongate endoscopic distal portion defining a distal tip through which each fastener of the plurality of fasteners is dispensed; and

a crenellated tip projecting distally from the distal tip of the endoscopic distal portion.

14. The instrument according to claim 13, wherein the instrument includes a driver subassembly disposed within the elongate endoscopic distal portion and movable relative to the endoscopic distal portion.

15. The instrument according to claim 14, wherein the elongate endoscopic distal portion includes an outer tube that is positioned to be urged to a distally advanced position.

16. The instrument according to claim 15, further including a pilot disposed within the outer tube, the pilot having a tapered surface on a distal end of the pilot.

17. The instrument according to claim 16, wherein each fastener of the plurality of fasteners is cannulated defining a lumen therethrough, and wherein the pilot extends through the lumen of each fastener.

18. The instrument according to claim 13, wherein the elongate endoscopic distal portion includes a fastener retainer dimensioned to receive at least one fastener of the plurality of fasteners.

19. The instrument according to claim 13, wherein the elongate endoscopic distal portion is securable to a handle assembly.
