Abstract
A method of reinforcing or repairing a bioprosthetic tissue for use as a prosthetic valve leaflet. The method includes evaluating a bioprosthetic tissue, identifying a defect in the bioprosthetic tissue, and selectively applying an adhesive to a surface of the bioprosthetic tissue at the defect prior to implantation in a patient.
Claims18
A method of reinforcing a bioprosthetic tissue for use as a prosthetic valve leaflet, comprising:
- evaluating a bioprosthetic tissue, the bioprosthetic tissue comprised of harvested naturally occurring tissue or synthetic material;
- identifying at least one defect in the bioprosthetic tissue;
- and
- selectively applying an adhesive to a surface of the bioprosthetic tissue at the at least one defect to locally reinforce or repair the bioprosthetic tissue prior to assembling the tissue into a prosthetic valve.
1 more element
A valve assembly, comprising:
- a valve frame;
- and
- prosthetic valve leaflets formed of bioprosthetic tissue assembled to the valve frame with mounting members, the bioprosthetic tissue comprised of harvested naturally occurring tissue or synthetic material, at least one of the prosthetic valve leaflets including a defect and including an adhesive applied at a select area including the defect to locally reinforce or repair the bioprosthetic tissue at the defect, wherein the defect comprises a fenestration or a separation of tissue layers, and wherein the defect is reinforced or repair prior to the prosthetic valve leaflets being assembled to the valve frame.
