Abstract

An implantable support apparatus includes a sheet of a flexible biocompatible material having apertures formed through end portions thereof to provide suture holes. A plurality of relatively larger apertures are formed through an intermediate portion of the sheet located between the end portions of the sheet to promote adhesion and improve integration of the apparatus into a patient'"'"'s body.

Claims

1. An implantable support apparatus comprising:

a sheet of a flexible biocompatible material having first and second end portions, said first and second end portions of said sheet being spaced apart by a length of said material, a first plurality of first apertures extending through said sheet near said first end portion and a second plurality of said first apertures formed through said sheet near said second end portion, a plurality of second apertures formed through an intermediate portion of said sheet spaced from and located intermediate said first and second pairs of first apertures wherein said plurality of second apertures being different from said plurality of first apertures.

2. An apparatus as set forth in claim 1 wherein said biocompatible material is a biological tissue material.

3. An apparatus as set forth in claim 2 wherein said biological tissue material is pericardium.

4. An apparatus as set forth in claim 2 further including a third pair of said first apertures extending through a part of said sheet located between said plurality of second apertures and said first pair of said first apertures, a fourth pair of said first apertures extending through a part of said sheet located between said plurality of second apertures and said second pair of said first apertures, each of said first and second pairs of first apertures being arranged for alignment with the respective third and fourth pairs of said first apertures so that, upon folding a part of each of said first and second end portions toward the opposite end portion, a folded end portion is formed at each end of said sheet with aligned ones of said first apertures providing reinforced suture holes that extend through each of said folded end portions.

5. An apparatus as set forth in claim 2 wherein each of said second apertures has a cylindrical sidewall extending between first and second surfaces of said sheet, said cylindrical sidewall of said second apertures having a diameter that is greater than the diameter of each of said first apertures so that, when implanted, surrounding tissue embeds into said second apertures to facilitate integration of said apparatus into the surrounding tissue.

6. An apparatus as set forth in claim 5 wherein said sheet of biological material is a first sheet and said apparatus further includes a second sheet of biocompatible material connected over a surface of said first sheet intermediate said first and second end portions of said first sheet, said second apertures extending through both said first sheet and said second sheet.

7. An implantable tissue support apparatus comprising:

a sheet of flexible, biocompatible biological tissue material having first and second end portions, said first and second end portions of said sheet being spaced apart by a length of said tissue material; and

a plurality of apertures formed through said sheet at locations spaced from and intermediate said end portions of said sheet.

8. An apparatus as set forth in claim 7 wherein said sheet of tissue material is a first sheet and said support further includes a second sheet of biocompatible tissue material connected over at least part of a surface of said first sheet intermediate said first and second end portions of said first sheet, said plurality of apertures being formed through both said first sheet and said second sheet.

9. An apparatus as set forth in claim 8 further including suture holes formed through said first sheet of tissue material near each of said end portions, each of said suture holes having a diameter that is less than the diameter of each of said plurality of apertures.

10. An implantable support apparatus comprising:

a sheet of a flexible biocompatible material having first and second end portions, said first and second end portions of said sheet being spaced apart by a length of said material, a first pair of first apertures extending through said sheet near said first end portion and a second set of said first apertures extending through said sheet near said second end portion, a plurality of second apertures extending through an intermediate portion of said sheet spaced from and located intermediate said first and second sets of first apertures, a third set of said first apertures extending through a part of said sheet located between said plurality of second apertures and said first set of said first apertures, a fourth set of said first apertures extending through a part of said sheet located between said plurality of second apertures and said second set of said first apertures, each of said first and second sets of first apertures being arranged for alignment with the respective third and fourth sets of said first apertures so that, upon folding a part of each of said first and second end portions toward the opposite end portion, a folded end portion is formed at each end of said sheet with aligned ones of said first apertures providing reinforced suture holes that extend through each of said folded end portions.

11. An implantable support apparatus comprising:

a sheet of a flexible biocompatible material having first and second end portions, said first and second end portions of said sheet being spaced apart by a length of said material, a first set of first apertures extending through said sheet near said first end portion and a second set of said first apertures extending through said sheet near said second end portion, a plurality of second apertures extending through an intermediate portion of said sheet spaced from and located intermediate said first and second sets of first apertures, each of said second apertures having a cylindrical sidewall extending between first and second surfaces of said sheet, said cylindrical sidewall of said second apertures having a diameter that is greater than the diameter of each of said first apertures so that, when implanted, surrounding tissue embeds into said second apertures to facilitate integration of said apparatus into the surrounding tissue.

12. An implantable support apparatus comprising:

a first sheet of a flexible biocompatible material having first and second end portions, said first and second end portions of said sheet being spaced apart by a length of said material, a first set of first apertures extending through said sheet near said first end portion and a second set of said first apertures extending through said sheet near said second end portion, a plurality of second apertures extending through an intermediate portion of said sheet spaced from and located intermediate said first and second sets of first apertures; and

a second sheet of biocompatible material connected over a surface of said first sheet intermediate said first and second end portions of said first sheet, said second apertures extending through both said first sheet and said second sheet.
