Abstract
A surgical fastener is disclosed, and includes a head section and a tissue snaring section. The head section includes an engagement member pivotably disposed on an outer surface of the head section. The tissue snaring section defines a longitudinal axis and extends away from the head section. At least one helical thread defined along an outer surface of the tissue snaring section. The tissue snaring section is configured to rotate about the longitudinal axis in a first radial direction, and the engagement member is configured pivot outwardly from the head section in the first radial direction.
Claims16
A surgical fastener comprising:
- a head section including an engagement member pivotably disposed on an outer surface of the head section;
- and
- a tissue snaring section defining a longitudinal axis and extending away from the head section, at least one helical thread defined along an outer surface of the tissue snaring section;
- wherein the tissue snaring section is configured to rotate about the longitudinal axis in a first radial direction, and the engagement member is configured pivot outwardly from the head section in the first radial direction.
A surgical fastener comprising:
- a head section including an engagement member pivotably disposed on an outer surface of the head section;
- and
- a tissue snaring section defining a longitudinal axis and extending away from the head section, at least one helical thread defined along an outer surface of the tissue snaring section;
- wherein the engagement member is configured such that, in a first condition of the surgical fastener, the engagement member is disposed radially inward with respect to the outer surface of the head section such that a first transverse head section diameter is defined, and in a second condition of the surgical fastener, the engagement member is disposed radially outward with respect to the outer surface of the head section such that a different, second transverse head section diameter is defined.
A method of deploying a surgical fastener including a head section including an engagement member pivotably disposed thereon and a tissue snaring section extending away from the head section, comprising:
- loading the surgical fastener in a delivery device such that the engagement member of the head section is disposed in a first, radially constrained configuration;
- and
- advancing the surgical fastener out of the delivery device such that the engagement member pivots radially outward with respect to the outer surface of the head section in a second, deployed configuration.
