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. A method for securing a surgical mesh to a target tissue site, the method comprising:

positioning the surgical mesh adjacent to the target tissue site;

supporting the surgical mesh against the target tissue site with a crenellated distal tip of an elongate endoscopic distal portion of a fastener applier before the fastener applier is fired; and

rotating a fastener driver within the elongate endoscopic distal portion of the fastener applier to dispense at least one fastener from the crenellated distal tip of the elongate endoscopic distal portion to secure the surgical mesh to the target tissue site.

2. The method claim 1, further comprising advancing the at least one fastener along a pilot of the fastener driver, the pilot extending through the at least one fastener.

3. The method of claim 2, further comprising simultaneously advancing the at least one fastener and a second fastener along the pilot and through an outer tube of the elongate endoscopic distal portion.

4. The method of claim 3, further comprising dispensing the at least one fastener and a second fastener from the crenellated distal tip and into the surgical mesh.

5. The method of claim 1, further comprising actuating a trigger mechanism of the fastener applier to advance the at least one fastener through the elongate endoscopic distal portion.

6. The method of claim 1, further comprising resiliently flexing a distal end portion of the fastener driver to retain the at least one fastener at the distal end portion of the fastener driver prior to releasing the at least one fastener from the distal end portion of the fastener driver.

7. A method for performing a surgical procedure, the method comprising:

positioning a surgical mesh over a target tissue site;

engaging the surgical mesh against the target tissue site with a crenellated distal tip of an elongate endoscopic distal portion of a fastener applier before the fastener applier is fired;

rotating a fastener driver within the elongate endoscopic distal portion of the fastener applier to advance at least one fastener along the crenellated distal tip of the elongate endoscopic distal portion; and

securing the at least one fastener to the surgical mesh and the target tissue site.

8. The method of claim 7, further comprising advancing the at least one fastener along a pilot of the fastener driver, the pilot extending through the at least one fastener.

9. The method of claim 8, further comprising simultaneously advancing the at least one fastener and a second fastener along the pilot and through an outer tube of the elongate endoscopic distal portion.

10. The method of claim 9, further comprising dispensing the at least one fastener and a second fastener from the crenellated distal tip and into the surgical mesh.

11. The method of claim 7, further comprising actuating a trigger mechanism of the fastener applier to advance the at least one fastener through the elongate endoscopic distal portion.
