Expanding seal anchor for single incision surgery
First Claim
1. A surgical anchoring apparatus configured and dimensioned for positioning within tissue, which comprises:
- a body member having proximal and distal ends, and defining a longitudinal body passage extending along a longitudinal axis of the body member, the body member including an expandable section adapted to transition between a first initial condition and a second expanded condition, wherein the body member includes a grip segment adapted for manual engagement by a user depending radially outwardly relative to the longitudinal axis of the body member, the grip segment being adapted to transition between a normal state and an at least partially inverted state, the grip segment being secured to the proximal end of the body member such that the grip segment extends proximally from the body member;
a dilator element at least partially positionable within the longitudinal passage of the body member, and being dimensioned to cause the expandable section to transition to the second expanded condition during insertion of the dilator element in the longitudinal passage, to thereby facilitate securement of the body member relative to tissue, the dilator element defining a longitudinal dilator passage for reception and passage of a surgical object; and
a seal secured to the dilator element, the seal adapted to establish a substantial sealing relation with the surgical object received within the dilator element.

Abstract
The present disclosure relates to a surgical anchoring apparatus for use during a minimally invasive surgical procedure. The surgical anchoring apparatus includes a body member and a dilator element at least partially positionable therein. The body member includes a grip segment adapted for manual engagement by a user and an expandable section having a plurality of expandable segments and a plurality of cam surfaces. The grip segment resiliently transitions between a first or normal state and a second state in which the grip segment is at least partially inverted. The expandable section'"'"'s cam surfaces are configured to engage a distal end of the dilator element upon its insertion such that the expandable section may transition from an initial condition to an expanded condition in which the body member is secured or anchored within an incision in tissue.

14. A surgical anchoring apparatus configured and dimensioned for positioning within tissue, which comprises:
-
a grip segment configured and dimensioned for engagement with an outer surface of the tissue, the grip segment being adapted to transition between a normal state, wherein a peripheral portion of the grip segment is oriented towards the tissue, and an at least partially inverted state, wherein the peripheral portion of the grip segment is oriented away from the tissue; an expandable section having a proximal end secured to the grip segment such that the expandable section extends distally from the grip segment, and a distal end opposite the proximal end, the expandable section defining a longitudinal axis, and being configured and dimensioned for movement between an initial condition and an expanded condition; and a dilator element configured and dimensioned for insertion into the expandable section to cause the expandable section to transition to the second expanded condition during advancement of the dilator element through the expandable section to thereby facilitate securement of the expandable section relative to the tissue. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 29)
