  • GATE WIRE FOR CONTRALATERAL LEG ACCESS
    Publication number: 20140194970
    Abstract: An endovascular delivery system includes a pre-loaded, small guide wire for snaring via the contralateral side of a bifurcated prosthesis for deployment of a graft extension to the contralateral side of the bifurcated prosthesis. The pre-loaded guidewire avoids a cannulation step in the deployment of typical bifurcated stent grafts. Deployment methods using the pre-loaded guidewire and endovascular grafts having a pre-routed lumen for a secondary contralateral access guidewire are also described.

  • Virtual prototyping and testing for medical device development
    Patent number: 8666714
    Abstract: A system and method of developing better-designed medical devices, particularly cardiovascular stents and endovascular grafts. The system comprises a geometry generator, a mesh generator, a stress/strain/deformation analyzer, and a visualization tool.
