Abstract
Embodiments of the invention may be directed to apparatuses for securing and sealing tissue and related methods of use.
Claims49
An apparatus, comprising:
- an outer housing defining a first lumen;
- an elongate member defining a second lumen, the elongate member being configured to be disposed in the first lumen;
- and
- a securing mechanism configured to secure tissue around a distal portion of the elongate member,
- wherein the elongate member and the outer housing are longitudinally moveable relative to each other.

(canceled)
An apparatus, comprising:
- an elongate member defining a lumen;
- an elongate assembly configured to be disposed in the lumen, the elongate assembly and the elongate member longitudinally moveable relative to each other;
- and
- a securing mechanism configured to secure tissue around a distal portion of the elongate member.

(canceled)
A method, comprising:
- advancing an outer housing defining a first lumen through a body lumen;
- advancing an elongate member defining a second lumen through the first lumen;
- forming a perforation in a wall of the body lumen;
- advancing a distal portion of the elongate member through the perforation;
- and
- securing body tissue surrounding the perforation to the distal portion of the elongate member with a securing mechanism.
3 more elements
30-36. (canceled)
A method, comprising:
- advancing an elongate assembly into a body lumen, the elongate assembly including a distal portion and a dilation portion;
- forming a perforation in a wall of the body lumen by piercing the wall with the distal portion;
- advancing the dilation portion into the perforation;
- expanding the perforation by activating the dilation portion;
- after the step of expanding the perforation, advancing a distal portion of an elongate member defining a lumen into the perforation;
- and
- securing body tissue surrounding the perforation to the distal portion of the elongate member with a securing mechanism.

46-47. (canceled)
An apparatus, comprising:
- an outer housing defining a lumen;
- a lip disposed on a distal end of the outer housing and configured to accommodate tissue thereon, the lip having a cross-sectional area smaller than a cross-sectional area of the outer housing adjacent to the lip;
- and
- a securing mechanism configured to secure tissue around the lip.
1 more element
(canceled)
An apparatus comprising:
- an elongate assembly having a distal portion configured to form a perforation in tissue, and a dilation portion configured to expand the perforation.
A method comprising:
- providing a first elongate member proximate an aperture in a wall of tissue, wherein the first elongate member includes a lumen and a securing mechanism;
- providing a second elongate member disposed within the lumen of the first elongate member and extending through the aperture;
- pulling tissue surrounding the aperture toward the first elongate member;
- and
- deploying the securing mechanism about the tissue surrounding the aperture to secure the tissue surrounding the aperture to the second elongate member.
