  • Surgical heart valves adapted for post-implant expansion
    Patent number: 9375310
    Abstract: A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander.
    Type: Grant
    Filed: December 20, 2013
    Date of Patent: June 28, 2016

  • High pressure vascular balloon catheter
    Patent number: 6629952
    Abstract: The present invention relates to a high pressure vascular balloon catheter wherein the walls of the tube attached to the balloon-forming segment are reinforced with a braided ribbon member. The walls of the inner tube that provides the lumen for a guidewire may also be reinforced in the same way. The reinforcement has the dual effect of providing strength against rupture under pressure and prevention of ovalizing or kinking during insertion into tortuous vessels of a vascular system.
