1. A prosthetic implant, comprising:
- a circumferentially adjustable sealing collar having a central longitudinal axis;
a rotatable sealer gear coupled to and disposed within the sealing collar and configured to adjust the circumference of the sealing collar, wherein the sealer gear is radially offset relative to the central longitudinal axis of the sealing collar, wherein rotating the sealer gear in a first direction relative to the sealing collar circumferentially expands the sealing collar, and wherein rotating the sealer gear in a second direction relative to the sealing collar circumferentially contracts the sealing collar; and
a locking member comprising a bar, wherein the bar of the locking member is selectively movable between a released state and an engaged state relative to the sealer gear.

Abstract
A prosthetic implant includes a circumferentially adjustable sealing collar and a rotatable sealer gear. The sealing collar has a central longitudinal axis. The rotatable sealer gear is coupled to and disposed within the sealing collar and configured to adjust the circumference of the sealing collar. The sealer gear is radially offset relative to the central longitudinal axis of the sealing collar. Rotating the sealer gear in a first direction relative to the sealing collar circumferentially expands the sealing collar. Rotating the sealer gear in a second direction relative to the sealing collar circumferentially contracts the sealing collar.
