Publication number: 20200093593Abstract: 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: ApplicationFiled: November 25, 2019Publication date: March 26, 2020Inventors: Visith Chung, Da-Yu Chang, Brian S. Conklin, Grace Myong Kim, Louis A. Campbell, Donald E. Bobo, JR., Myron Howanec, David S. Lin, Peng Norasing, Francis M. Tran, Mark Van Nest, Thomas Chien, Harvey H. Chen, Isidro L.

Publication number: 20200060816Abstract: A valved conduit including a bioprosthetic valve, such as a heart valve, and a tubular conduit sealed with a bioresorbable material. The bioprosthetic heart valve includes prosthetic tissue that has been treated such that the tissue may be stored dry for extended periods without degradation of functionality of the valve. The bioprosthetic heart valve may have separate bovine pericardial leaflets or a whole porcine valve. The sealed conduit includes a tubular matrix impregnated with a bioresorbable medium such as gelatin or collagen. The valved conduit is stored dry in packaging in which a desiccant pouch is supplied having a capacity for absorbing moisture within the packaging limited to avoid drying the bioprosthetic tissue out beyond a point where its ability to function in the bioprosthetic heart valve is compromised. The heart valve may be sewn within the sealed conduit or coupled thereto with a snap-fit connection.Type: ApplicationFiled: October 28, 2019Publication date: February 27, 2020Inventors: Louis A. Campbell, Donald E. Bobo, JR., Gregory A. Wright, Tak G. Cheung

Publication number: 20180221016Abstract: Suture locking clamps for securing prostheses such as heart valves or annuloplasty rings with sutures and without using knots improve the ease of implantation. The clamps have opposed clamp halves separated by a slot opening to one side and surrounded by a biasing member such as one or more C-clip springs. Sutures pass laterally into the slot which is held open by a retention member positioned between the clamp halves. The locking clamp slides along the sutures into position, the tension of the sutures is adjusted, and the retention member removed to allow the biasing member to clamp the sutures between the clamp halves. A delivery tool used to deliver and deploy the locking clamps contains a number of clamps within a delivery tube in a stack and bonded together for safety and a common retention member. The tool has a longitudinal channel on one side for entry of sutures.Type: ApplicationFiled: April 3, 2018Publication date: August 9, 2018Inventors: Brian S. Conklin, Louis A. Campbell, Salvador Marquez, Donald E. Bobo, Jr.
