Abstract

Disclosed are fenestration coverings, procedural drapes, and methods thereof. For example, a fenestration covering is configured to cover a fenestration in a procedural drape for a medical procedure. The fenestration covering includes a transparent sheet of polymeric material and a non-adhesive central portion of the fenestration covering. The transparent sheet has a length and width sufficient to cover the fenestration and allow a clinician to manipulate the patient, one or more pieces of procedural equipment or supplies, or a combination thereof under the fenestration covering. The central portion of the fenestration covering is greater than or coextensive with the fenestration. An example method includes forming a fenestration in one or more procedural drapes for a medical procedure and covering the fenestration with the fenestration covering.

First claim

What is claimed is:

1 . A procedural drape for a medical procedure, comprising:
a first opaque sheet of one or more nonwoven materials, the first opaque sheet having a length and width sufficient to establish a procedural field about a patient for the medical procedure; a transparent sheet of polymeric material on a side of the first opaque sheet forming a laminate with the first opaque sheet, the transparent sheet coextensive with the length and the width of the first opaque sheet; a second opaque sheet of one or more nonwoven materials on a side of the transparent sheet, thereby further forming the laminate; and one or more removable pieces of the first opaque sheet configured for respectively forming one or more fenestrations in the first opaque sheet upon removal of the one or more removable pieces, one or more fenestrations in the second opaque sheet matching the one or more fenestrations in the first opaque sheet when formed, and one or more fenestration coverings of the transparent sheet covering the one or more fenestrations of the first opaque sheet when formed, wherein the one or more fenestration coverings are breachable by a piece of procedural equipment.

2 . The procedural drape of claim 1 , wherein the one or more removable pieces have perforated or precut perimeters configured to facilitate removal of the one or more removable pieces.

3 . The procedural drape of claim 1 , wherein the one or more removable pieces include a reusable adhesive configured for adhering the one or more removable pieces to the transparent sheet.

4 . The procedural drape of claim 1 , further comprising margins around a central portion of the procedural drape, the margins including a pair of opposing longitudinal margins and a pair of transverse margins in which at least one pair of margins of the pairs of opposing longitudinal and transverse margins includes a same or different reusable adhesive configured for adhering one or more procedural drape surfaces.

5 . The procedural drape of claim 1 , further comprising margins around a central portion of the procedural drape, the margins including a pair of opposing longitudinal margins and a pair of transverse margins in which at least one pair of margins of the pairs of opposing longitudinal and transverse margins includes a single-use adhesive configured for adhering one or more procedural drape surfaces.

6 . The procedural drape of claim 1 , wherein the first opaque sheet includes one or more plies, each ply of the one or more plies of the one or more nonwoven materials selected from a polypropylene or a wood pulp.

7 . The procedural drape of claim 6 , wherein the first opaque sheet includes a single ply of spunbond polypropylene.

8 . The procedural drape of claim 6 , wherein the first opaque sheet includes a single ply of spunlace wood pulp.

9 . The procedural drape of claim 6 , wherein the first opaque sheet includes one ply of meltblown polypropylene between two plies of spunbond polypropylene.

10 . The procedural drape of claim 1 , wherein the polymeric material is a breathable polyethylene, a polypropylene, or a polyurethane.

11 . The procedural drape of claim 1 , wherein the polymeric material is impregnated with a broad-spectrum antimicrobial.

12 . The procedural drape of claim 1 , wherein the procedural drape is a sterile procedural drape.

13 . A procedural drape for a medical procedure, comprising:
a first opaque sheet of one or more nonwoven materials, the first opaque sheet having a length and a width adapted to establish a procedural field about a patient for the medical procedure; a transparent sheet of polymeric material on a side of the first opaque sheet forming a laminate with the first opaque sheet, the transparent sheet coextensive with the length and the width of the first opaque sheet; a second opaque sheet of one or more nonwoven materials on a side of the transparent sheet, thereby further forming the laminate; and one or more fenestrations in the first opaque sheet, one or more fenestrations in the second opaque sheet matching the one or more fenestrations in the first opaque sheet, and one or more fenestration coverings of the transparent sheet covering the one or more fenestrations of the first opaque sheet, wherein the one or more fenestration coverings are breachable by a piece of procedural equipment.

14 . The procedural drape of claim 13 , wherein the polymeric material is impregnated with a broad-spectrum antimicrobial.

15 . The procedural drape of claim 14 , wherein the broad-spectrum antimicrobial is an iodophor.

16 . The procedural drape of claim 13 , further comprising margins around a central portion of the procedural drape, the margins including a pair of opposing longitudinal margins and a pair of transverse margins in which at least one pair of margins of the pairs of opposing longitudinal and transverse margins includes a reusable adhesive configured for adhering one or more procedural drape surfaces.

17 . The procedural drape of claim 13 , further comprising margins around a central portion of the procedural drape, the margins including a pair of opposing longitudinal margins and a pair of transverse margins in which at least one pair of margins of the pairs of opposing longitudinal and transverse margins includes a single-use adhesive configured for adhering one or more procedural drape surfaces.

18 . The procedural drape of claim 13 , wherein the first opaque sheet includes one or more plies, each ply of the one or more plies of the one or more nonwoven materials selected from a polypropylene and a wood pulp.

19 . The procedural drape of claim 18 , wherein the first opaque sheet includes a single ply of spunbond polypropylene.

20 . The procedural drape of claim 18 , wherein the first opaque sheet includes a single ply of spunlace wood pulp.

21 . The procedural drape of claim 18 , wherein the first opaque sheet includes one ply of meltblown polypropylene between two plies of spunbond polypropylene.

22 . The procedural drape of claim 13 , wherein the polymeric material is a breathable polyethylene, a polypropylene, or a polyurethane.

23 . The procedural drape of claim 13 , wherein the procedural drape is a sterile procedural drape.
