  • Patent number: 7914438
    Abstract: A ventricular patch to restore the ventricular architecture of the heart includes a sheet of biocompatible material having a generally oval configuration, and a continuous ring fixed to the sheet. The ring has a generally oval configuration similar to the generally oval configuration of the sheet of biocompatible material. The ring defines a central generally oval region of the patch inside the ring and a circumferential region of the patch outside of the ring. The central generally oval region has a major axis and a minor axis. The ratio of the major axis to the minor axis is about 4:1.
    Type: Grant

  • Patent number: 7275546
    Abstract: The symptoms of congenital heart failure are addressed in this surgical procedure for mounting a patch in the ventricle of the heart to reduce ventricular volume. Placement of the patch is facilitated by palpating a beating heart to identify akinetic, although normal appearing, tissue. An apical patch having an oval configuration facilitates return of the heart to a normal apical shape which enhances muscle fiber efficiency and a normal writhing pumping action. An inferior patch having a triangular configuration can also be used. The patches include a semi-rigid ring, and a circumferential rim to address bleeding. Patch placement is further enhanced by creating a Fontan-type neck and use of pledged sutures. Intraoperative vascularization and valve replacement is easily accommodated. Increased injection fraction, reduced muscle stress, improved myocardial protection, and ease of accurate patch placement are all achieved with this procedure.
