IN-SITU GRAFT FENESTRATION
First Claim
1. A robotic system for deploying a medical lumen graft, comprising:
- A. a remotely steerable flexible instrument having proximal and distal ends and a graft fenestration element coupled to its distal end, the graft fenestration element configured to controllably create a fenestration through a wall of a deployed graft;
B. a controller in communication with a master input device; and
C. an instrument driver operatively coupled to the controller and the proximal end of the flexible instrument, the instrument driver configured to cause controlled steering movement of the flexible instrument in accordance with input signals received by the controller from the master input device.

Abstract
Assemblies, systems, and methods related to in-situ graft fenestration are described. Subsequent to placement of a graft or stent graft into a lumen, such as a blood vessel, a steerable catheter platform is utilized to create fenestrations, or holes, into the material comprising the graft to facilitate flow of fluids, such as blood, out of the holes and into other structures, such as side branch vessels. The catheter platform preferably comprises one or more fenestration elements located distally and configured to controllably create the fenestrations through common graft materials, such as Dacron®. The catheter also may be utilized to size and/or locate side branching structures, confirm fenestration sizes and/or locations, and deploy additional grafts through the fenestrations into other branching structures.

19. A method for deploying a lumen graft, comprising:
-
a. deploying a parent lumen graft in a parent lumen; b. determining one or more locations to create fenestrations in the deployed parent lumen graft by utilizing a electromechanically-controlled catheter system configured to determine position information pertinent a distal tip of a steerable catheter comprising the catheter system; and c. creating one or more fenestrations in the parent lumen graft by utilizing a fenestration element coupled to the distal tip of the steerable catheter. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
