Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
119 words
A method of using a ventricular patch to restore the ventricular architecture of the heart, comprising: providing a ventricular patch including a sheet of biocompatible material having a longitudinally elongated configuration; a continuous ring fixed to the sheet and having a generally longitudinally elongated configuration similar to the longitudinally elongated configuration of the sheet of biocompatible material, the ring defining a central longitudinally elongated region of the patch inside the ring and a circumferential region of the patch outside of the ring, the central longitudinally elongated region having a length and a width, the ratio of the length to the width being greater than 2:1; restoring the conical apex of the heart using the ventricular patch within the ventricle.
Claim 2
Independent Claim
119 words
A method of using a ventricular patch to restore the ventricular architecture of the heart, comprising: providing a ventricular patch including a sheet of biocompatible material having a longitudinally elongated configuration; a continuous ring fixed to the sheet and having a generally longitudinally elongated configuration similar to the longitudinally elongated configuration of the sheet of biocompatible material, the ring defining a central longitudinally elongated region of the patch inside the ring and a circumferential region of the patch outside of the ring, the central longitudinally elongated region having a length and a width, the ratio of the length to the width being greater than 2:1; restoring the conical apex of the heart using the ventricular patch within the ventricle.
