1. A transluminal system comprising:
- an elongate guide tube extending between a proximal portion and a distal portion and including at least one channel for the passage of a tool, the guide tube including an articulation section driven by a proximal control mechanism; and
a port movably mated with the guide tube and including at least one mating element for mating with an anatomic wall to maintain an opening in the anatomic wall, wherein the port permits movement of the guide tube with respect to the port after mating the port with the anatomic wall;
wherein the elongate guide tube includes a surface feature having a diameter greater than the opening, the surface feature being moveable through the opening with the elongate guide tube such that the surface feature directly contacts the anatomic wall; and
wherein the elongate guide tube includes a side portal proximal to the port, the side portal having an angled configuration to permit viewing the port as it mates with the anatomic wall.

Abstract
Disclosed herein are various systems and methods for traversing an anatomic wall. A system can include a port that mates with an anatomic wall and provides a lumen for the passage of a guide tube of a transluminal device. The port can inhibit the passage of biological materials through the anatomic wall. Further described herein are methods for implanting the port and/or for inserting the transluminal device into a body cavity.

23. A transluminal system comprising:
-
an elongate guide tube extending between a proximal portion and a distal portion and including at least one channel for the passage of a tool, the distal portion of the guide tube having at least one distal opening; a port including a proximal mating element and a distal mating element for mating with an anatomic wall to maintain an opening in the anatomic wall, the port further including a lumen for receiving at least a portion of the elongate guide tube, and an elongate body extending proximally from the port and defining a passageway for receiving the guide tube, wherein the guide tube is insertable through the passageway and through the port, and wherein the guide tube includes a surface feature having a diameter greater than the opening in the anatomic wall, the surface feature being moveable through the opening in the anatomic wall with the elongate guide tube such that the surface feature directly contacts the anatomic wall; wherein the proximal mating element includes a pivoting flange configured to pivot away from the lumen and toward the distal mating element at substantially the same time; and wherein the elongate guide tube includes a side portal proximal to the port, the side portal having an angled configuration to permit viewing the port as it mates with the anatomic wall. - View Dependent Claims (24, 25, 26)

27. A method of traversing an anatomic wall, comprising:
-
creating an opening in an anatomic wall; passing at least a portion of an elongate guide tube through the opening, the elongate guide tube movably mated with a port having a proximal-most end and a distal-most end, wherein the proximal-most end of the port includes a first mating element comprising a flange and the distal-most end of the port includes a second mating element, wherein the elongate guide tube includes a side portal proximal to the port, the side portal having an angled configuration to permit viewing the port as it mates with the anatomic wall, and wherein the portion of the elongate guide tube that passes through the opening includes a distal tip and a surface feature having a diameter greater than the opening to contact the anatomic wall; contacting the anatomic wall with the surface feature; after contacting the anatomic wall with the surface feature, passing the distal-most end of the port through the opening such that the second mating element is distal to the anatomic wall and the flange is proximal to the anatomic wall; rotating the flange outward from the port; and mating the port with the anatomic wall via the rotated flange. - View Dependent Claims (28, 29, 30, 31, 32, 33)

34. A transluminal system comprising:
-
an elongate guide tube extending between a proximal portion and a distal portion and having at least one channel, wherein the guide tube includes a distally-located articulation section driven by a proximally-located control mechanism; and a port having a lumen configured to slidingly receive the guide tube and a first mating element configured to mate a proximal-most end of the port to an anatomic wall to maintain an opening in the anatomic wall, wherein the first mating element includes a flange moveable radially to couple to the anatomic wall; wherein the elongate guide tube includes a surface feature distal to the first mating element and having a diameter greater than the opening, the surface feature being movable through the opening with the elongate guide tube such that the surface feature contacts the anatomic wall to determine a location of the first mating element relative to the opening; and wherein the elongate guide tube includes a side portal proximal to the port, the side portal having an angled configuration to permit viewing the port as it mates with the anatomic wall. - View Dependent Claims (35, 36, 37, 38)
