Abstract
Disclosed herein are embodiments of devices and methods for forming a seal covering an incision in tissue. In some embodiments, a deformable member can be loaded into a catheter and inserted into the tissue incision. The deformable member can unfold into a cup-shape which can form a seal around the incision during a procedure. Once the procedure is finished, the deformable member can be drawn back into the tube.

-13. (canceled)
A method for creating an anastomosis site along a wall of a blood vessel without interrupting the flow of blood through the blood vessel, the method comprising:
- inserting a hollow elongated member through an opening in the wall of the blood vessel;
- advancing a deformable sealing member located within the hollow elongated member into the blood vessel, wherein after advancing, the deformable sealing member is located distal to the hollow elongate member and expands from a compressed configuration to an enlarged configuration having a cup shape with a sealing ring located at a rim of the cup shape;
- and
- creating a seal between the deformable sealing member and the wall of the blood vessel by moving the deformable sealing member proximally, the seal surrounding the opening in the wall of the blood vessel, the cup shape forming a cavity that defines the anastomosis site.
(canceled)
A method for creating an anastomosis site along a wall of a blood vessel without interrupting the flow of blood through the blood vessel, the method comprising:
- inserting a hollow elongated member through an opening in the wall of the blood vessel, a distal end of the hollow elongated member configured to extend through the opening;
- advancing a deformable sealing member located within the hollow elongated member into the blood vessel, wherein after advancing, the deformable sealing member is located distal to the hollow elongate member and expands from a compressed configuration to an enlarged configuration, the deformable sealing member comprising a flexible cover;
- creating a seal between the deformable sealing member and the wall of the blood vessel by moving the deformable sealing member proximally to engage a magnetic ring of the deformable sealing member with a first side of body tissue surrounding the opening;
- applying a magnetic portion on a second side of body tissue opposite the first side to magnetically attract the magnetic ring;
- detaching the magnetic portion from the magnetic ring;
- and
- removing the deformable sealing member from the blood vessel by moving the deformable sealing member into the hollow elongated member, wherein the deformable sealing member is inverted when moved into the hollow elongated member.
