ABSTRACT:
A prosthetic heart valve includes a hydrogel material in its sewing cuff. The hydrogel material may be accompanied by an anticoagulant. If the hydrogel (and/or any included anticoagulant) might react with a packaging solution in which the valve is stored after inclusion of the hydrogel (and any anticoagulant), the hydrogel (and any anticoagulant) may be included in a protective but deliberately frangible pouch in the sewing cuff. After the valve is out of the packaging solution, the pouch can be broken to render the hydrogel (and any coagulant) effective following implantation of the valve in a patient.
