Abstract
An endograft (102) includes a stent structure. An optical shape sensing (OSS) system (104) is associated with the endograft and is configured to measure shape, position and/or orientation of the stent structure. The OSS system (104) is connected to the stent structure and removable in a plurality of ways. Methods for deployment and removal of the OSS system are also provided.
Claims26
An endograft, comprising:
- a stent structure;
- at least one attachment mechanism configured to releasably attach to the stent structure;
- and
- at least one optical shape sensing (OSS) system having one or more optical fibers, wherein said optical shape sensing system is coupled to the at least one attachment mechanism and is configured to measure at least one of shape, position or orientation of the stent structure.
An endograft, comprising:
- a stent structure;
- at least one deployable instrument pre-cannulated through a fenestration in the stent structure;
- and
- the at least one deployable instrument including an optical shape sensing (OSS) system having one or more optical fibers, wherein said optical shape sensing system is configured to measure at least one of shape, position or orientation of the stent structure and align the fenestration with a branch of a blood vessel for placement of the endograft.

An endograft, comprising:
- a stent structure having a wall;
- a lumen formed within the wall of the stent structure;
- and
- an optical shape sensing (OSS) system having one or more optical fibers, wherein said optical shape sensing system is configured to pass into the lumen, to be releasably secured to the stent structure and to be configured to measure at least one of shape, position or orientation of the stent structure.
An endograft, comprising:
- a stent structure having a lumen with concentric supporting members;
- an eye formed with at least one of the concentric supporting members;
- and
- an optical shape sensing (OSS) system having one or more optical fibers, wherein said optical shape sensing system is configured to pass through the eye, to be releasably secured to the stent structure and to be configured to measure at least one of shape, position or orientation of the stent structure.

A method for endograft deployment, comprising:
- deploying at least one optical shape sensing (OSS) system associated with an endograft, said optical shape sensing system having One or more optical fibers;
- measuring at least one of shape, position or orientation of the endograft during deployment using the at least one OSS system;
- registering OSS data with image data on a blood vessel where the endograft is placed;
- anchoring the endograft in the blood vessel;
- and
- removing at least a portion of the OSS system from the endograft.
