  • Patent number: 8170307
    Abstract: A computer implemented method of processing MRI images to determine one or more characteristics of an anatomical feature that includes obtaining one or more first MRI images of the anatomical feature; identifying a boundary of an anatomical feature in the MRI images; and using the identified boundary to mask one or more corresponding second MRI images of the anatomical feature to isolate the anatomical feature within the second MRI images.

  • Patent number: 7060022
    Abstract: The present invention relates to decellularized vascular prostheses that are resistant to thrombus occlusion and have a low level of immunogenicity. The vascular prostheses are denuded of cells, and coated with an anti-thrombogenic agent and a growth factor that promotes recellularization and further reduces the immunogenicity. The prostheses have high mechanical strength, resist aneurysm rupture, and allow for secure surgical sutures while maintaining structural integrity. The present invention provides vascular prostheses that are blood vessels, valves or portions of vessels containing valves. The present invention is also useful for coating synthetic vascular stents.

  • Patent number: 5928135
    Abstract: A method for removing a vessel from a patient's body comprises the steps of identifying the vessel to be removing and providing an incision in the patient's body near the identified vessel. An optical dissector is inserted through the incision and tissue is optically dissected away from the surface of the vessel with the optical dissector. The optical dissector is then withdrawn from the body through the incision. An optical retractor is inserted into the body through the incision and is used to retract the dissected tissue away from the surface of the vessel thereby providing space between the dissected vessel and the retracted tissue. The vessel and its side branches are then dissected, ligated and transected and the vessel is then removed from the body through the incision.
