A method for deploying a device in a tortuous vessel, comprising:

Anatomical visualization and measurement system

A method for determining the risk of rupture of a blood vessel using an appropriate set of 2-D slice images obtained by scanning the blood vessel, the method comprising: generating a mesh model of the blood vessel using the set of 2-D slice images; conducting finite element stress analysis on the mesh model to calculate the level of stress on different locations on the mesh model; and determining the risk of rupture of the blood vessel based on the calculated levels of stress on different locations on the mesh model.

Method and apparatus for determining the risk of rupture of a blood vessel using the contiguous element defined area

There is provided a method and apparatus for determining the risk of rupture of a blood vessel using a set of 2-D slice images obtained by scanning the blood vessel. The invention includes elements and steps for generating a mesh model of the blood vessel using the set of 2-D slice images, conducting finite element stress analysis on the mesh model to calculate the level of stress on different locations on the mesh model and determining the risk of rupture of the blood vessel based on the calculated levels of stress on different locations on the mesh model.

Method for determining the risk of rupture of a blood vessel

Apparatus and method for producing a virtual road map of a patient's vascular anatomy comprising a virtual 3D model of the patient's vascular and bony structure in proper registration with one another, a fluoroscope for providing real-time images of the bony structure of the patient, registration apparatus for placing the virtual 3D model in proper registration with the patient space of the fluoroscope, bone mask subtraction apparatus for generating a bone mask of the bony structure, and subtracting the same from the real-time images, whereby to create modified fluoroscope images omitting bony structure, and image generating apparatus for generating the virtual road map comprising a composite image combining (i) images of the virtual 3D structure representing the vascular structure, and (ii) modified fluoroscope images omitting bony structure, wherein the images of the virtual 3D structure representing vascular structure are in proper registration with the modified fluoroscope images omitting bony structure.

Method and apparatus for visualizing anatomical structures

A method for determining the degree of twist to be manually introduced into an implant which is to be positioned in the aorta and adjacent iliac branches so as to achieve an effective degree of twist when the implant is positioned in the anatomy, the method comprising:

A method and apparatus for generating a computer model from scan data from a patient, comprising:

Using statistical process control (SPC) to demonstrate solution convergence in a technician guided segmentation system

A computer-based visualization system for visualizing an anatomical structure and a graft implant which is to be deployed adjacent the anatomical structure, comprising: a 3-D computer model of the anatomical structure to be visualized, the 3-D computer model comprising at least one first software object which corresponds to the anatomical structure to be visualized; a database of second software objects, wherein at least one of the second software objects corresponds to a graft implant which is to be deployed adjacent the anatomical structure; selection apparatus for permitting a user to select at least one of the second software objects; registration apparatus for positioning the selected at least one of the second software objects into the 3-D computer model so as to create an augmented 3-D computer model; and processing apparatus for generating an image of the augmented 3-D computer model.
